2. Abstract
Wireless broadband operators constantly face challenges of balancing the economics to deploy a robust and reliable
wireless broadband service in suburban-rural areas or at cell-edges. Till to date, a large portion of these areas still
remains hugely underserved or receiving unreliable coverage. Most available studies have shown that WiMAX is indeed
an ideal technology candidate not only for a suburban-rural deployment, but as a wireless broadband technology on an
overall, with most of the studies focusing on infrastructure performance.
This paper in retrospect functions to further solidify the technological advantage of WiMAX, where we explore and proof
the concept of suburban-rural deployment through the optimal pairing of a proper CPE strategy. We will show that the
best solution for suburban-rural area and cell-edge performance can be extended four times through deployment via
outdoor CPEs.
This paper explores deep into the technical and implementation advantages of an outdoor CPE solution, including the
concept of antenna gain, transmission power, integrated POE design and environment-proof enclosure; and the effective
advantage of Line of Sight performance and decreased penetration loss amongst other features of an outdoor CPE. We
will also explore the misconception behind the high incremental cost, difficulty of engineering installation and service
challenges in operations with the implementation of an outdoor CPE which has been the lead culprit towards the low
adoption of this CPE strategy. Greenpacket will share three reference cases where deployment through the OX series
outdoor CPE has shown great success in Australia, Africa and Haiti, from a performance and business implementation
perspective.

3. Introduction
One major challenge for wireless broadband operators is to successfully deploy in a suburban-rural morphology. This
challenge is inherent with disregard of the type of wireless technologies implemented, be it through WiMAX, Satellite, 3G,
CDMA and similarly in the future, with LTE. In our previous white paper “Improving Indoor Coverage: How WiMAX
Modems can Play a Major Role in the Subsystem” (WPWIC10), we have described technologies to improve user
experience when they are farther away from the base station, or in the cell-edge area. We can see that in general,
cell-edge represents the area where poor consistency in connectivity is prevalent, with typical modulation being QPSK
where cell-edge users generally experience low and in many cases, inconsistent throughput speeds.

The figure below represents a typical wireless cell that has a cell-center with radius ‘r’ and cell edge with a radius of ‘2r’.
Tabulating the coverage area, the cell-edge would give us an area of coverage equivalent to 4πr², while the cell-center is
only πr². Showing the distinct differences in coverage area achieved between the cell-edge and cell-center. This direct
difference implies that the efficiency of spectrum utilization by the base station is not able to achieve its intended
maximum coverage and capacity capability unless higher modulation scheme can be extended further into the cell-edge
coverage area; without which, a decent robust connectivity is next to impossible by just relying on the base station itself.

4. WiMAX As The Best Solution With Outdoor CPE
Challenges For Rural Broadband Deployment
Broadband penetration in rural areas across the world has lagged far behind than that in urban areas, both in developed
countries as well as in developing countries. This is mainly due to multiple reasons which make providing coverage in
these areas economically non-viable. The main reasons for this low penetration lie within the following TOP 3
roadblocks:
• As population density in rural areas is relatively low, setting up and maintaining copper or fiber lines to provide
broadband service across the “last mile” incurs high costs for Internet Service Providers (ISPs)
• Capacity on the backhaul or the “middle mile” from the ISP to the Internet backbone is often very limited and
expensive as it is provided over facilities designed for voice telephony or cable television
• The difference in per capita income between rural areas and urban regions means that broadband services need to
be offered at a lower-price point in the rural areas in order to gain customer adoption.
This combination of high CAPEX/OPEX and low Average Revenue per User (ARPU) has traditionally made the rural
broadband market less lucrative for service providers, but the advent of new high speed mobile broadband technologies
such as WiMAX has rapidly changed the situation.

5. WiMAX As The Ideal Solution For Rural Broadband Deployments
As operators around the world evaluate multiple technologies for rural broadband deployments, WiMAX is emerging as
the de-facto standard. The advantages offered by WiMAX have time and again proven its commercial viability, among
others:
• Infrastructure Effectiveness: WiMAX offers a highly cost effective solution to address the rural broadband conundrum
as physical infrastructure need not be rolled out to individual customer premises on the last mile. This significantly
reduces the overall cost and the time-to-market in deploying the network.
• Flexible Network Deployment: WiMAX allows operators to surgically choose deployment options and focus on
specific areas where there is strong demand.
• High Data Throughput: 802.16e has reached a stage of technology and standards maturity with field proven results
that shows data throughput of over 40Mbps (@10MHz channel bandwidth).
• Spectrum Concerns: WiMAX spectrum has typically been less expensive worldwide as compared to 3G licenses.
Additionally, with mobile WiMAX being on licensed band, operators can deploy rural broadband networks with no
spectrum-related concerns.
The largest challenge facing operators in deploying a suburban/rural service is to create a balanced business case that
allows them to maximize the access infrastructure capability from a coverage and capacity perspective and at the same
time to deliver a robust and reliable service with a positive revenue return. Greenpacket believes that this can be realized
effectively if ‘Line Of Sight’ (LOS) can be achieved through the pairing of Outdoor CPE to the network, where we will
investigate the technology, performance and reveal a detailed deep dive reference case study based on a suburban/rural
environment profile.

6. Advantages Of Outdoor CPE
The right CPE strategy for cell-edge and suburban/rural area is to deploy Outdoor CPE, and from our experience,
outdoor CPE have the following advantages.
i. Improved Uplink Technologies
ii. High Transmission Power And High Gain Directional Antenna
iii. Zero Penetration Loss
iv. Further Improvements Due To Line Of Sight
v. When Compared To External Antenna Option, Minimal Cable Loss
vi. Environmentally Robust
vii. Easy Installation
viii. Plug And Play
(i) Improved Uplink Technologies
We have stated a comprehensive analysis of the importance of uplink technologies in our previous white paper “A
Practical Approach to Improve WiMAX Indoor Coverage.” Here, we briefly describe the most important technology Dual
transmitter (2TX) which is implemented in our OX series Outdoor CPE.
Dual Transmitter (2Tx) (CDD)
The simplest Dual Transmitter technology employs Cyclic Delay Diversity (CDD) algorithm and signals are transmitted via
a single data stream through two antennas and two power amplifiers – hence, both antennas are switched on and used
for transmission. The combined power from two PAs provides approximately an additional perceived 3dB gain with
potentially lower power consumption (if PA’s are tuned to a lower power). This arrangement improves uplink performance
and lengthens coverage through better signal strength; however, it increases the cost of the modem as more
components are used.
Dual Transmitter (2Tx) STC Matrix (Uplink MIMO A)
The second generation Dual Transmitter technology further employs Space Time Coding signaling algorithm (Uplink
MIMO A) instead of just (CDD) algorithm as previously mentioned. However, in order to support this new algorithm, base
stations need to be upgraded to support WiMAX R1.5. The hardware implementation is the same as Dual Transmitter
(CDD) where transmission is conducted through two antennas and two power amplifiers. The combined power from two
PAs provides approximately an additional perceived 4dB gain, which is better than the Dual Transmitter (CDD).

7. (ii) High Transmission Power And High Gain Directional Antenna
Comparatively, Outdoor CPEs are designed with higher maximum transmit EIRP. Greenpacket OX series Outdoor CPE
has a 14dBi antenna, Dual transmitters (2Tx) with a combined Tx power rated at 27dBm, thus a maximum transmit EIRP
equivalent to 41dBm, making it the most powerful mobile WiMAX CPE in the market today. Directional antenna is
conventionally implemented to optimize the antenna performance specifically aligned to face towards the base station.
Different from an indoor or USB based device, operator will normally assign service engineers to the premise where
installation is based on the optimum facing direction and upon locating it, the outdoor antenna is locked into place.
Figure 3 shows a sample antenna pattern for the 2.5GHz model. The diagram shows a concentrated RF energy radiated
in a single direction (+- 10 degrees within the pink line). This specific radiation pattern plays the highest role of effectively
increasing the coverage area.

APPLICATION NOTE

8. (iii) Zero Penetration Loss
Throughout our deployment experience, depending on the depth and material of the building, Glass windows and
concrete walls induces a 6dB and 12dB penetration loss respectively where the implementation through indoor CPEs
will normally endure. An Outdoor CPE, being placed normally on the roof of a specific building has the advantage of
being subjected to zero penetration loss, even without line-of-sight (LOS).
Figure 5: Frequency Vs Depth of penetration (Pd) for representative profiles of clay soils of pune at different soil moisture
conditions (weight %)
(iv) Further Improvements With Line Of Sight (LOS)
The key advantage for Outdoor CPE is that it can easily achieve Line of Sight (LOS) with proper mounting. Having
achieved Line of Sight (LOS), there is no longer a multi-path problem and we can ensure optimal RF path between the
CPE and the base station. Figure 6 shows how Line of Sight can be achieved by moving the CPE above the roof with a
pole.

Figure 6: Improvement of LOS with o utdoor CPE
In addition, studies show that for a full featured base station. To achieve the same transmission data rate of 11Mbps,
LOS cell radius can be as far as 30km, while Non Line of Sight (NLOS) cell radius is only limited to 4km. This accounts
for five times the radius or about 25 times more coverage area for the same base station. LOS is a very critical
06
factor that affects the performance of the network, where an Outdoor CPE is proven to be the ideal solutions
to achieve LOS.

(v) Outdoor CPE VS Indoor CPE + External Antenna: Minimal Cable Loss
Another common solution to achieve LOS performance is to use outdoor external antenna to connect to an indoor CPE.
However, using external antenna introduces cable losses. For example, we can see in the below diagram, a typical cable
used for external antenna is RG316, which introduces about 1.5dB loss per meter length. Therefore, for an outdoor
extension of 10m, this contributes to 15dB loss, which has similar magnitude as the typical outdoor external Antenna
gain. This limitation is not absolute, where external antenna solutions with super high gain (greater than 15dBi) and super
low loss cable (less than 0.5dB/m) can be found, the question is however extended to economic sense of forming a
realistic solution rather than the best solution.

11. Uncover The Myth about Outdoor CPE
There exist general misconceptions about outdoor CPE implementation in terms of cost, having extreme restriction on
being heavy, performing unreliably under changing weather conditions, and extremely difficult to install and service.
New advancement on design and architecture has changed all this, Greenpacket’s OX series outdoor CPE is an example
where cost is effectively affordable, weighing in at less than 2kg, flexibly mountable on a wall or pole or roof edge and
capable of enduring temperatures between - 40°C ~ 60°C while in operations.
Most importantly, OX series enclosure is certified to be IP67 compliant which comes with a protection against the effects
of immersion in water up to depth of 1 meter. POE (Power over Ethernet) cable is also an important feature which
ensures that only a single cable (RJ45) is stretched from the outdoor unit (ODU) directly indoors to the end user, where
both the power and data is carried.
(i) Environmentally Robust
In addition, OX series outdoor CPE is equipped with a robust mounting kit which has been certified to withstand severe
windward and crosswinds. Figure 8 show the test result for OX series outdoor CPE withstanding hurricane rated winds
(windward/crosswind under 60m/s for 10 minutes, Beauford Wind Force Scale 17)

13. The Rural Leapfrog – ENDING THE WAIT FOR RURAL
CONNECTIVITY
Verifying It On The Field
Understanding the concept and technological advantage of mobile WiMAX coupled with the service offering via an
Outdoor Modem validates it as a viable solution option for rural connectivity. The bigger question remains on the
performance capability of the WiMAX outdoor modem when deployed in a commercial field that is subjected to
subscriber loading and the environmental uncertainties knowing historically the inherent limitation of implementation via
a wireless technology.
Vivid Wireless, is the first WISP to launch a mobile WiMAX network in Australia has had a successful service uptake since
its launch in April 2010 covering the urban and suburban areas in cities of Perth, Sydney and Melbourne via Indoor IADs
and USB modem. Looking to extend its service coverage to the fringing suburban and semi-rural areas within the city,
Vivid Wireless conducted a citywide evaluation to benchmark the performance of the OX outdoor modem. Vivid Wireless
wanted the performance test to be conducted on its commercially live network to ensure that the end results obtained
is strictly similar to the end user experience. Choosing to compare it against the current commercially offered Green
Packet high gain DX Indoor IAD, Vivid Wireless has the objective:-
1. To ensuring that the OX meets the technical specification as stated in its product datasheet.
2. To record the additional gain in coverage, and
3. To record the throughput speeds experienced

15. Reaching Within Remote Africa
Direct-on-PC, a the leading operator in Nigeria has been deploying mobile WiMAX under the service name of Unwired
by extending its wireless broadband voice and data services covering sub-urban and rural developing communities in
selective areas of Lagos, Abuja and Port-Harcourt as a complimentary broadband access network to their existing VSAT
and fixed wireless networks. The flexibility of mobile WiMAX has allowed the operator to grow its service coverage area
flexibly as service demand grows.
The strategy of service implementation via outdoor based CPE creates the best service advantage as it allows
maximization of coverage making the service robust and reliable, perfect to the harsh conditions of the West African
nation.
With mobile WiMAX having the capacity efficiency that is 10x higher with an upfront subscriber acquisition cost that is
1/5 of current satellite network, the business case of providing affordable voice and broadband service is achievable. This
has created confidence that the 4G network plans is set to lay the foundation for growth, both for the company and to
the development of the underserved market.
Bringing Broadband To The Remote Islands
The islands of the Caribbean are a well known holiday destination with a developing community and economy. Providing
broadband services in islands with harsh environmental terrain has always been a challenge to service providers.
Digicel International has been the champion serving over 11 million customers across 32 markets mainly on the islands
of the Caribbean and the Pacific. Having launched mobile WiMAX in Haiti, Digicel has had a great success with its
pay-as-you surf mobile WiMAX services in suburban areas of Haiti currently providing robust fast broadband services
through Greenpacket indoor and USB based devices.
Looking to extend the services offering in rural and remote areas, with the service quality having similar robustness is
something that Digicel insist to maintain, in order to achieve this while not having to incur huge incremental CAPEX
investment by deploying additional infrastructure to these subscribers located mainly in fringing cell edge of the network.
The outdoor modem was evaluated and results has proved to be the perfect solution extending the coverage within a
healthy modulation scheme to achieve broadband speeds and consistent service.
Even with a higher subscriber acquisition cost via the outdoor modem implementation, the huge CAPEX/OPEX savings
from infrastructure spending allows Digicel to scale the deployment needs with the number of subscription growth.
