- The document summarizes key points from the LTE World Summit, including that carrier aggregation allows more effective spectrum utilization and helps level the playing field between operators with different amounts of spectrum. It allows dynamic load balancing between non-contiguous LTE bands.
- The availability of LTE-Advanced and carrier aggregation increases theoretical peak data rates for most LTE subscribers from ~75Mbps to ~150Mbps. Higher throughput will particularly benefit users at the cell edge or in challenging RF conditions and when networks are congested.
- While higher speeds sound exciting, typical mobile users may not notice major differences except when downloading large files, as web pages and most transactions don't require more than a few megabits per second
LTE & Wi-Fi: Options for Uniting Them for a Better User ExperienceAricent
Most national governments consider the radio spectrum a valuable national resource and heavily regulate its commercial use. Governments typically auction off licenses for the right to transmit over a portion of the spectrum, which can be very expensive. The traditional business model for cellular
carriers is based on access to this licensed business has coalesced worldwide around a single 4th generation (4G) radio technology standard called Long Term Evolution, commonly referred to as LTE.
LTE is a common standard covering both FDD and TDD flavors, enableing the industry to build common FDD/TDD infrastructure, common devices, and a large common ecosystem. LTE and its evolution LTE Advanced play a critical role in addressing the 1000x increase in mobile data.
Qualcomm has been leading LTE proliferation from the very beginning— from the industry-first Gobi LTE/3G multimode, common FDD/TDD modems to the current third-generation solutions that powered the world’s first LTE Advanced carrier-aggregation launch in June 2013.

The final piece to solving the 1000x puzzle is squeezing higher efficiency out of all the resources. More small cells and more spectrum are key to 1000x, but we also need enhancements that increase the network efficiency and squeeze more capacity and value out of spectrum. Apart from interference management that brings more out of small cells, we need to 1) Improving the efficiency of the apps and services 2) Make the data pipe more efficient by evolving 3G/4G/Wi-Fi and 3) Introduce a smarter pipe.

Qualcomm: Making the best use of unlicensed spectrumQualcomm Research
In solving the 1000x challenge, licensed spectrum is the foundation. Equally important is utilizing available unlicensed spectrum. The best way to achieve this is to combine both of them through aggregation. Aggregation brings seamless user experience, better coverage and capacity, as well as the efficiencies of a common unified network. Operators have a choice on how to aggregate, and the decision depends on their current assets and future network plans.
Explore our this presentation and other resources to find out when, and how to choose? How can LTE-U coexist fairly with Wi-Fi in 5GHz unlicensed spectrum? What roles existing/new Wi-Fi, and LTE-U play? And whether it really is a "either or" decision.

3GPP LTE-A Standardisation in Release 12 and Beyond - Jan 2013 Eiko Seidel, C...Eiko Seidel
Quite some time ago major improvements have been made to LTE with LTE-Advanced as part of 3GPP Release 10. Unquestionably, LTE-A will be the leading global 4G standard fulfilling the defined ITU-R requirements [1] on IMT-Advanced such as peak data rates beyond 1Gbps. While further enhancements to LTE-Advanced have just been completed in 3GPP Release 11, the new technology trends become visible to serve the continuously growing traffic demand. This White Paper, based on Nomor’s attendance of 3GPP, provides an outlook on 3GPP standardisation for the forthcoming years. Besides a summary of general trends and a projected release schedule, it includes an overview of the work and study items of Release 12 in the Radio Working Groups. New key technologies that Release 12 will address are: Small Cell Enhancements, a New Carrier Type, 3D-MIMO Beamforming, Machine-Type-Communication, LTE-WiFi Integration at radio level and Public Safety incl. Device-to-Device communication. While the completion of Release 12 is expected mid of 2014, deployments might be seen around the end of 2015 and later. NoMoR is active in different related research projects and offers consultancy services for related research, standardisation, simulation, early prototyping and technology training.

Memorandum Of Association Constitution of Company.pptseri bangash
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder

SETTING THE STAGE FOR
LTE-ADVANCED AND CARRIER
AGGREGATION
(plus updates following the LTE World Summit)
2. 2 | SignalsFlash February 21, 2013
EXECUTIVE SUMMARY
Last week we attended the LTE World Summit in Amsterdam. In this special issue of Signals Flash! we provide
some highlights and key takeaways from the event. Apologies for being late on our next Signals Ahead report,
but we’ve got numerous things in the works – just nothing ready to print. A pending trip to the East where we
plan to dine on Bee-Bim Bop along with doing other activities that should be of more interest to our readers
won’t help matters any…
Key Highlights
➤➤ The availability of LTE-Advanced, specifically carrier aggregation, will result in more effective spectrum utiliza-
tion and help level the playing field between the 20 MHz Have’s and Have Not’s.
➤➤ VoLTE was a hot topic with more commercial launches likely last this year and into 2014.
➤➤ Roaming via LTE is looming, or at least the technical barriers are coming down.
➤➤ Network innovation driven by virtualization (Cloud RAN, SDN, etc.) and technology enablers like 4x4 MIMO
are occurring concurrently with the move to LTE-Advanced.
➤➤ Small cells are big.
➤➤ The business case for LTE looms large with most operators.

worthy events, Signals Flash! provides readers with a summary of past and planned research
reports that we offer through our subscription-based Signals Ahead research product. We have
also taken the opportunity to promote a couple of our most recent reports for readers of this

SETTING THE STAGE FOR LTE-ADVANCED AND CARRIER
AGGREGATION
1) The availability of LTE-Advanced, specifically carrier aggregation, will
result in more effective spectrum utilization and help level the playing field
between the 20 MHz Haves and Have Nots. Last week, SK Telecom announced that it had
launched commercial LTE-Advanced services, specifically carrier aggregation, throughout much
of greater Seoul and other important regions in South Korea with plans for even greater coverage
later in the year. We believe that the LGU+ carrier aggregation launch is imminent followed by
Korea Telecom (KT).
All operators are using the Samsung Galaxy S4 with the Qualcomm Snapdragon 800 chipset,
which suggests that Samsung reverted, at least temporarily, back to Qualcomm for its in-country
chipset requirements. Previously, we were of the understanding that Samsung was using an inter-
nally-developed chipset in the S4 for the domestic market, just as it used its own chipset for the
Galaxy S3. We know all credible LTE chipset suppliers have near-term CA aspirations and Samsung
and LG (thanks to government financial backing) should support the feature in their commercial
chipsets, perhaps by the end of the year. Intel could surprise with an earlier than anticipated
market entry and Broadcom is heavily focused on the feature. We’ve yet to test Broadcom’s
Release 8 LTE solution so we will withhold judgment on their LTE capabilities for the moment.
Many chipset suppliers are initially targeting 10 MHz + 10 MHz implementations of carrier aggre-
gation, and this is evident in the Galaxy S4. Sequans is one chipset supplier that is initially focused
on 20 MHz + 20 MHz – it demonstrated the capability earlier this year at MWC. This means that
the peak end user throughput is “limited” to 150 Mbps with a Category 4 device. Worth noting, in
addition to being the industry’s first LTE-Advanced smartphone/device, the Galaxy S4 is also the
industry’s first commercially-available Category 4 device. With a 20 MHz + 20 MHz implementa-
tion, peak speeds of 300 Mbps are possible, just as peak speeds of 300 Mbps are possible with 4
x 4 MIMO in a 20 MHz channel.
Although chipset support for a 20 MHz + 20 MHz implementation sounds great on paper, there
isn’t a major pull from the market forces. By and large, the operators with the largest LTE deploy-
ments only have channel bandwidths of 10 MHz while in some cases the channel bandwidths are
limited to 5 MHz. Something like 90% of all LTE subscribers belong to operators that fall into this
category. The 5 MHz limitation is true for AT&T in certain markets, including Chicago, and we
believe it is also true for one of the bands that NTT DoCoMo currently supports with LTE. In the
case of the South Korean operators, SK Telecom has deployed LTE at 800 MHz and 1800 MHz, KT
The LTE networks with the
largest number of subscribers
are generally limited to
no more than 10 MHz of
contiguous spectrum.
4. 4 | Signals Flash July 1, 2013
has deployed LTE at 900 MHz and 1800 MHz, and LGU+ has deployed LTE at 800 MHz and 2100
MHz. All deployments are limited to no more than 10 MHz of contiguous spectrum.
For these operators, carrier aggregation allows them to compete on a more level playing field
with their peers. In the case of AT&T, for example, it must compete with Verizon Wireless, despite
the latter operator having 10 MHz channel bandwidths in all of its markets. In many parts of the
country, AT&T also lacks the virgin 1700 MHz spectrum that it relinquished to T-Mobile following
its failed merger attempt. If it had retained the spectrum, it might have been able to deploy a 10
MHz LTE carrier. AT&T had between 5 MHz and 15 MHz of paired spectrum at 1700 MHz across
the entire country prior to giving a lot of the spectrum to T-Mobile. We haven’t done the analysis
to determine what it currently has and where it has it, but we surmise that its ability to deploy LTE
in 2 x 10 MHz of contiguous spectrum has been greatly diminished, barring any pending spectrum
deals that may be in the works.
In addition to leveling the playing field, carrier aggregation provides an operator with the ability
to do fairly dynamic load balancing between its noncontiguous bands of LTE. In effect, the mobile
device is simultaneously connected to both radio channels and receiving as much resources as
the network will schedule it, albeit on two independent radio carriers, versus a single radio carrier.
It is up to the operator to determine how much bandwidth to assign to each mobile device, but
presumably it is in the operator’s best interest to allocate as many resources as possible on both
radio carriers in order to get the mobile device off the network.
Load balancing could still be done via SON or using a solution, such as Huawei’s Single Radio
Controller (SRC), but it wouldn’t be as dynamic and it would require inter-frequency handovers.
To a large degree, this capability is the most compelling advantage of carrier aggregation. The
operator receives a direct benefit while the end user receives an indirect benefit. We demon-
strated as much in our initial drive testing of DC-HSDPA versus HSPA+ and we’ll be demonstrating
the same thing when we publish our drive test report on carrier aggregation in the not-too-
distant future.
The possibility for higher peak data rates sound exciting, and it is, but depending on the use case
the typical mobile data consumer may not notice the difference. Worth noting, with the simulta-
neous introduction of CA and Cat 4 devices the theoretical peak data rates for nearly all existing
LTE subscribers increases from ~75 Mbps to ~150 Mbps. In our user experience drive test report
that we published back in 2011 (SA 10/19/11, “Quantifying the User Experience”) we demonstrated
that higher data rates didn’t necessarily lead to a better user experience. For example, web pages
won’t load any faster once the throughput is higher than a few Megabits-per-second, and users
probably won’t discern the fractional second savings with other transactions that involve the
amount of transferred data in a typical transaction. With the current implementation of carrier
aggregation the aggregation only occurs in the downlink so uploading a video to YouTube will
take just as long as it previously did. Obviously, the impact will be evident when using Speedtest.
net, and this outcome is great for marketing purposes.
In other cases, higher throughput will matter and it will have a material impact on the user experi-
ence. This situation could occur at the cell edge or when challenging RF conditions exist. When
network congestion is present, the benefits of the second radio carrier should also be evident to
the end user when dealing with applications that require somewhat higher bandwidth. In all cases,
carrier aggregation will definitely benefit the end user when downloading large files and other
multimedia content, such as movies from iTunes, but very few consumers find themselves in this

situation due to operator tariff plans that limit them to only a few GB per month. Nothing beats
blowing a monthly allotment due to downloading a high definition version of Despicable Me 2.
Work in the standards bodies and commentary from operators at the LTE World Summit indicate
that carrier aggregation is moving in other directions as well. From a standards perspective, there
are efforts underway to logically combine 3 noncontiguous bands, for example 700 MHz, 1700
MHz and 1900 MHz (North America) or 800 MHz, 1800 MHz and 2600 MHz (Europe and Asia).
This is all fine and good, but our suspicion is that most operators would rather have RF front end
complexity applied to supporting more discrete bands for roaming with a single device.
Although also defined in the standard, the ability to support carrier aggregation from two
geographically separated cells – for example, involving a macro cell and a small cell – is closer to
reality. One of the vendors (we believe it was Huawei or Samsung) highlighted that it had already
demonstrated the capability and we know that other vendors have also invested effort in this
area. In theory, the concept sounds compelling and it is very comparable to HSPA+ Multiflow,
which NSN and Qualcomm demonstrated earlier in the year at MWC. However, we believe the
practicalities of deploying the capability will somewhat limit its adoption in the near-term. Close
coordinated scheduling is important to make the feature work well, and this requirement implies
the need for dark fiber and a centralized scheduler (a.k.a. cloud RAN). The most likely deploy-
ment scenarios are, therefore, markets in Asia or dense network deployments in other parts of
the world where there is ample dark fiber. Large stadiums come to mind.
At the show there was a lot of talk about carrier aggregation and it is evident that many operators,
including Verizon Wireless and EE are trialing the technology with commercial launches planned
for the coming year. Some operators, however, need to wait until chipsets support channel
bandwidths that are greater than 10 MHz. TeliaSonera, for example, indicated that it has at least
15-20 MHz radio channels in all of its markets so if it deployed carrier aggregation based on the
capabilities of existing solutions, it would have to reduce the channel bandwidth for all legacy
devices. In other words, not only would it not gain anything by deploying carrier aggregation it
would also have to sacrifice performance for most of its installed base of devices.
2) VoLTE was a hot topic with more commercial launches likely late this year
and into 2014. Not surprisingly, VoLTE was a hot topic at this year’s event. ALU started things
off with its pre-event analyst dinner where the focus was entirely on VoLTE (and eating). First off,
it was interesting and encouraging to witness ALU have such a strong presence at the event – an
event where we believe Ericsson was 100% absent and NSN only had a modest showing in a
nonofficial capacity. ALU, like its peers, highlighted many of the benefits of VoLTE and that while
implementing the new service won’t be easy, the benefits will outweigh the challenges. We also
agree with ALU that the last two years it spent working with AT&T and Verizon Wireless with
their VoLTE deployments will give them an advantage over many of their peers. This advantage,
however, is only in the near-term and it will need to capitalize on its early frontrunner status.
The benefits of VoLTE, according to ALU and others, include the following:
➤➤ Higher capacity (~6x GSM and ~3x UMTS)
➤➤ Better voice quality with AMR-WB

MetroPCS claims to have launched “VoLTE,” but from what we understand the launch is limited
to the Dallas market and devices aren’t widely available, if at all. LGU+ and SKT have launched
VoLTE, although some vendors have questioned whether or not it is fully standards compliant,
without fully explaining why they think it isn’t true VoLTE. Nonetheless, SKT and Samsung were
able to demonstrate a much faster call setup time – a couple of seconds at most versus nearly 10
seconds with CSFB. Looking ahead to later this year, AT&T will likely lead the charge with VoLTE
launches in at least a couple of regions later in 2013, followed by Verizon Wireless in 2014.
In order for VoLTE to become a reality most operators will need SRVCC to enable relatively
seamless handovers during a voice call when the mobile device moves outside of LTE coverage.
Orange, for example, reiterated the importance of SRVCC and after having spent the weekend
“drive testing” in the Loire Valley we can confirm that LTE doesn’t exist. We were lucky to find 3G
and in many cases we had to rely on EDGE to download Google Map navigation directions. For
this reason, it is a bit surprising that AT&T plans to launch in advance of Verizon Wireless given
that the latter operator has better coverage.
The consensus opinion is that operators will not be able to charge for VoLTE services and that
voice will be bundled with their data services. In the US, operators are already beginning to
bundle voice with their data services, or at least allow free mobile to mobile calls, so this outcome
wouldn’t be as dire as it sounds. However, in other markets operators are still charging for their
voice services.
We are not completely convinced that operators won’t be able to get something incremental for
delivering voice services versus OTT, but it will all depend on how they market their services and
the data bundles that they offer. For example, the operator’s self-branded voice service might
only be offered with certain data packages – data packages that were more expensive and which
included other features and capabilities. Consumers could still go with OTT applications, like
Skype, but the call quality wouldn’t necessarily be as compelling and there would be a greater
impact on battery life since the OTT application would run on the application processor while
the VoLTE client would remain on the baseband modem. Then again, the operator doesn’t want
its churn to increase so if one operator gives away VoLTE the other operators will have to follow.
One interesting observation that one vendor made is that when it comes to international roaming
voice calls, VoLTE will be inherently less expensive than an OTT application, such as Skype. This
result is because the data traffic must be routed back to the home operator’s network (also
higher latency) while the VoLTE traffic would remain in-country unless the call was placed to an
international number. This phenomenon could allow operators to introduce a pricing plan that

can be used to maximize performance when these challenging
conditions exist. For purposes of this report, we used AT&T’s
HSPA+ network in San Francisco and the surrounding vicinity. This
report was done in collaboration with Accuver who provided us
with its XCAL and XCAP drive test solutions.
➤ 4/25/13 “Everything under the SON” We discuss the
background of SON, including discussions of work within NGMN,
3GPP and the SOCRATES/SEMAFOUR projects. We also cover
the basics of SON including the laundry list of SON-like features,
explain how they work, and what they mean for operators and
vendors. We then move on to discuss the present and future
requirements of SON, including what may be in store with Release
12 and beyond. Finally, we discuss the motivations and challenges
of SON, including multi-vendor integration, vaguely-defined use

M2M services make it natural fit for cloud services so there will
need to be new cloud platforms in both the operator networks

the radio and core networks will require enhancements to support
the deluge of new M2M connections. We discuss some of the

makes VoLTE more attractive to consumers than Skype yet the operator still comes out ahead
because its network delivery cost is lower.
3) Roaming via LTE is looming, or at least the technical barriers are coming
down. Operator business cases and roaming agreements still need to be reached while the
need for multi-band devices is paramount.
By and large, LTE data roaming doesn’t exist. For most operators there are two primary reasons
– mobile devices don’t exist which support the hodge-podge of frequency bands where LTE has
been deployed and operators have yet to establish the business relationships.
TeliaSonera is an example of an operator that currently supports data roaming via LTE, although
the roaming is limited to a couple of different combinations involving only three of its properties
(Norway, Denmark and Sweden). On the bright side, the operator doesn’t charge data roaming
fees with some of its plans. If, for example, a subscriber in Sweden has a 5 GB plan and he uses 5
GB in Norway there wouldn’t be any additional data charges. This policy is consistent with what
the European Union is attempting to do throughout the 27-bloc European Union. Personally, we
are not convinced that data roaming charges should be abolished, but conversely we hate paying
the exorbitant rates that we are currently charged when we only use a token amount of data.
TeliaSonera International Carrier also signed a deal with iBasis (KPN), which, among other things,
will tie together the two carriers’ signaling infrastructure and data centers. This arrangement
will make it technically possible to cross-connect LTE voice calls that go across both carriers’
networks. Given that iBasis has agreements with Verizon, Vodafone, China Mobile, Telefonica and
TIM, to name a few, the agreement is pretty far reaching.
Even after the operators sign roaming agreements they will still need compatible handsets to
support true global roaming via LTE. Subscribers with an LTE handset that supports Band 3 (1800
MHz) should fair the best when traveling abroad given that the band probably has, or will soon
have, been deployed in the most countries, but anyone traveling to and from the US and Asia/
Europe will struggle for the foreseeable future. To some extent it is in the interest of operators
to drive the industry to support more bands in mobile devices and innovations in the RF front
end are helping in that regard. But from our perspective, we can’t afford more than 20-50 MB
of international data roaming at today’s rates, which equates to no more than 4 seconds of data
usage with an optimal data connection – realistically we might get as much as 16 seconds.
In all seriousness, HSPA+ and DC-HSDPA, along with Wi-Fi, should more than suffice for most
international data usage. We’ll get interested and excited about LTE data roaming when the tariffs
are reasonable and/or we win the lottery.
4) Network innovation driven by virtualization (Cloud RAN, SDN, etc) and
technology enablers like 4x4 MIMO are occurring concurrently with the
move to LTE-Advanced.
Separate from the evolution of the standard, operators and vendors were actively discussing
various innovations within the standard that can allow them to achieve additional efficiency.
These incremental efficiencies are critical since data usage continues to escalate while the mix of
data traffic is constantly changing. Figure 1 shows the distribution of data traffic on SK Telecom’s

network and how it varies between LTE and 3G devices. Not surprisingly, the percentage of multi-
media traffic increases with LTE (from 39.0% to 42.8%) and the percentage of Web browsing traffic
decreases with LTE (from 39.4% to 33.0%). More importantly, the average mobile data traffic per
user increases from 1.1 GB to 2.1 GB per month with LTE.
To address this issue, SKT is adopting an innovative traffic management system that dynami-
cally allocates resources based on the requirements of the application. For example, voice traffic
is very sensitive to delay than data traffic. Within the mix of data traffic, multimedia content
is more susceptible to delay than non-real time applications, like email. The operator is using
unspecified network intelligence to schedule network resources accordingly.
South Korea is unique in that the operators have adopted a “Cloud RAN” approach to their
network, although this network architecture isn’t universally deployed throughout all of the
country. Even in South Korea, dark fiber doesn’t exist everywhere. With a Cloud RAN, the base-
band units are centrally located and connected via dark fiber to remote radio units. When this
type of network architecture is possible it creates a tremendous amount of scheduling synergy
since all of the network scheduling occurs at a single location. This capability provides greater
coordination across and between individual network elements that may not be possible with a
decentralized approach. Samsung and Huawei both claimed a 30% gain in overall cell capacity
and more than a 100% gain in edge-of-cell capacity. A cynic might claim that the comparison is
done against an inferior decentralized scheduler, and to be fair it isn’t clear to us what exactly is
being compared.
Nonetheless, at least some of the South Korean operators are planning to launch early imple-
mentations of Uplink CoMP (Coordinated Multipoint) and eICIC later this year. Both features are
readily doable since the stringent X2 interface requirements, including ultralow latency and high
bandwidth, are easily addressed, and not even relevant, when the scheduling is done within a rack
of equipment.
KT’s network evolution strategy is called WARP+. It began with a centralized approach and
then incorporated “virtualization” in which the centralized baseband units are not specifically

dedicated to individual RRUs. As the next step, the operator is bringing in small cells and Wi-Fi
into the cloud-based approach. KT also discussed its ABC (always best connected) philosophy
which makes more intelligent use of Wi-Fi. With this approach, which intelligently shifts certain
traffic onto its Wi-Fi network, the operator as seen a 25% increase in mobile data traffic with the
Wi-Fi network carrying 41% of its data traffic – up from 16% without ABC turned on.
The message from Tekelec (now Oracle) was also about load balancing and virtualization, but in
its case the concept was applied to the core network, specifically diameter signaling traffic. With
the DSR (Diameter Signaling Router), operators are able to manage and redirect IP and signaling
traffic, which is critical for networks that must scale from token deployments to nationwide
network in a cost efficient manner while also retaining high reliability. We plan to cover the topic
of SDN in a dedicated piece sometime this fall.
Given that multiple events and presentations were going on at the same time and that we had
various obligations to fulfill, we missed out on some of the presentations that we wanted to
attend. Honorable mentions go to T-Mobile, who presented results from their 4x4 MIMO trials
(peak throughput = 250 Mbps in the field, 60-70% capacity gain over 2x2 closed loop MIMO and
80% edge of cell gains); Quintel, who is implementing an innovative approach to doing beam-
forming; and InToTally, who is offering a form of power control in 3G and LTE networks that can
meaningfully increase network capacity. We wish we could say more on all three companies/
presentations but we didn’t have the opportunity to sit throughout all of their presentations. We
will, however, revisit the topic of MIMO performance in the not-too-distant future.
5) Small cells are big. Most operators are strongly on board with the concept of small cells
and shifting traffic away from the macro layer – using cellular small cells, Wi-Fi, or a combination
of the two. HetNet and SON are paramount with the best opportunity for third party small cell
deployments occurring indoors.
Given the interest and attention being paid to small cells, it would be heresy for an operator
to discount the importance of small cells. However, the timing of when small cells will become
mainstream and the exact role that they will have in the network is still up for debate. At least a
couple of operators, including Vodafone, indicated that they are very open to using third-party
small cells in their network. However, they also felt that the best opportunity in the near-term
for third party suppliers was indoors since there is a natural interference barrier / demarcation
point that exists. Thick walls made of space age material that is designed to keep the heat/cold
in and the cold/heat out also do a great job of blocking RF energy.
Vodafone went on to debunk the moderator’s claim that small cells won’t happen because DAS
deployments are so large today. In the words of the operator, there are small cell solutions out
there that it likes which can dramatically scale to support dense deployments and large amounts
of traffic. Cost was also cited as a consideration point since DAS can be prohibitively expensive
in certain situations. We would add that DAS doesn’t necessarily scale for capacity but it is great
when it comes to providing a thin layer of coverage over a large geographic region.
Some operators, including TELUS (Canada) and KT have deployed small cells in the outdoor macro
network. From what we heard in the presentation, KT currently has 10,000 femto access points,
growing to 18,000 femto access points, which are publicly accessible (e.g., open to all subscribers).
KT is using its centralized scheduler and eventually eICIC to coordinate resources between the
small cells and the macro layer.

TELUS has deployed small cells in Vancouver. For 3G, the operator used dedicated spectrum but
with LTE the operator has experimented with co-channel deployments. In its commercial deploy-
ment the operator reserved certain resource blocks for the small cells while the macro cells used
frequency selective scheduling to assign resource blocks that would generate the least amount
of interference. With lighter traffic volumes, the two sets of cells would remain isolated in the
frequency domain but as traffic levels increased there would be some overlap.
From its tests, the operator saw meaningful performance gains, including an 80-100% increase in
uplink throughput. However, longer term the operator acknowledged that features, such as SON
and HetNet, will be critical. One other challenge that the operator cited pertains to cost. In this
particular case, the presented information pertained to HSPA+ so it isn’t clear to us whether or
not this issue extends to LTE. Specifically, the operator indicated that a 3G small cell site costs
1/5th the cost of a macro site, but the operator also requires 5-10 small cells per macro cell site
(recall, the operator was also using different spectrum for its small cell network so it probably
wanted to achieve fairly ubiquitous coverage). The distribution of cost for the small cell was also
interesting with 67% of the cost due to civil work and labor.
6) The business case for LTE looms large with most operators. Last year with the
economic situation in Europe the mood at the LTE World Summit was downright depressing. This
year it wasn’t necessarily upbeat but there also wasn’t any evidence of Prozac-popping senior
executives. Operators still felt compelled to justify their rationale to deploy LTE even if investors
weren’t in the room.
Orange presented its view on the network delivery cost for LTE versus HSPA+. According to its
analysis, LTE doesn’t become less expensive for the operator than HSPA+ until 2015. And when
it does become less expensive, the advantage isn’t huge, in particular to some of the marketing
claims that we’ve seen from some vendors. Although the operator didn’t provide absolute
numbers or discuss all of its underlying assumptions, Orange’s analysis is pretty similar to the
results that we’ve derived through various network economic modeling exercises that we have
done over the years. Without network traffic, the network delivery costs are infinite on a per
MB basis on any network. It is only with sufficient data traffic that a more efficient technology

becomes less expensive. Further, since a lot of the network delivery costs are technology agnostic
(e.g., site acquisition and leasing, as well as backhaul), it stands to reason that the costs are similar.
The South Korean operators are the envy of the land and whatever they are doing, they are doing
something right. Figure 3 shows the smartphone adoption by technology (3G versus LTE) and

Figure 5 provides the monthly data usage for the average LTE data subscriber and the total LTE

Fortunately, the LTE ARPU is meaningfully higher than the 3G ARPU (reference Figure 6), and
this is resulting in an upward swing in ARPU for all three operators, in particular LGU+ (reference
