What Should 5G Be About?
 5G should not be only about mobile technology – it is more than just “Cellular”
 5G ― ubiquitous access to high data services / applications from any device, anywhere, anytime. “ALWAYS
CONNECTED”
 To create such an environment, one needs to integrate various services applications, emerging from
various services and access via a mix of access to different fixed and wireless networks.
– It should also lower the net cost of service access (£ / month / Mbit) for consumers.
– 5G should be a multi-layered, multi-RAT heterogeneous network including 2G, 3G, 4G and RLAN.
– 5G terrestrial wireless should integrate / inter-work with other radio access technologies like Fixed
Satellite Service (FSS), Broadcast Satellite Service (BSS) & Mobile Satellite Service (MSS) Systems.
 This is also mentioned in the current ITU-R WP5D - 5G Vision

Satellite Play A Role in 5G Service Delivery
 Satellites can today deliver very high data rate services (> 100 Mbits/s – 1 Gbit/s) in ‘broadcast /
multi-cast’ mode to small radio access points.
 Satellite can today also deliver high capacity two-way ‘broadband’ services for complementary
coverage to fixed or terrestrial wireless networks outside major urban / suburban areas.
 Novel satellite transmission technologies, spectrum utilisation technologies, and receiver /
modem, network structures will rapidly mature and develop in coming years.

Level of Satellite Investment and Deployment Worldwide
 The Fixed Satellite Services market is expected to grow from $13.46 billion in 2014 to
$17.21 billion by 2019*

 UK-based satellite operators filing through OFCOM, for Ka-band systems within the 27.5 –
30.0 /17.3 – 20.2 GHz include:
 The current level of investment by ‘UK filing satellite operators’ in procured Ka-band satellite
systems alone is VERY HIGH:
 Without considering the huge investment in ground infrastructure and customer equipment,
each of which are projected to increase radically in the coming years.
 The Space sector contributes £11.3 billion a year to the UK economy and has been growing
at about 7% each year throughout the recession.* Much of that growth will be in Ka-band.

Debate - IMT/5G v Satellite
Satellite Advocates
• No adequate justification for 5G spectrum.
• Many of the frequency bands currently identified for
IMT are not used or not used efficiently.
• No ITU approved IMT terrestrial radio interfaces for
bands above 6 GHz (5Gis still undefined).
• Many space and terrestrial services operate using
bands above 6 GHz.
• Implementation of IMT terrestrial invariably leads to
displacement of incumbent terrestrial services and
space services.
• Sharing satellite services with high density mobile
networks is not realistic/ not feasible.
IMT/5G Terrestrial Advocates
It is necessary to consider a new agenda item for WRC-
19 related to IMT terrestrial above 6 GHz.
• IMT / 5G is the future technology beyond 3G / 4G.
• IMT / 5G will provide high data rate video while users
are on move
• IMT terrestrial is on research stage and will issue the
radio interfaces for bands above 6 GHz in future.
• Much more spectrum (e.g. > 1 GHz) required to
deliver much higher data rates for future 5G services.
Is a repeat of C-band
WRC saga over 10
years positive for the
ITU ?

9. Avanti - Confidential - Commercial in Confidence | 13 February, 2015 | 9
There is a proposal to consider additional spectrum allocation above 6 GHz to IMT terrestrial
OK, Well ??? But what about incumbent services ??!
WRC-15 Future Agenda Item 10
 Some terrestrial entities have proposed to consider between 6 GHz up to 100GHz!!!
 The mobile community is asking a future Agenda Item at the upcoming WRC-15 to be
considered into the next cycle of WRC-18
 However the Mobile community say it is too early to identify spectrum and further
studies are need
 This poses a number of difficulties:
This MAYBE (??) fair enough
But why not specify certain frequency ranges now?
Will there be enough time from Nov 2015 until WRC-18 to conduct studies?
Is it possible to identify a harmonised global approach between 6 GHz and 31 GHz with so many existing
allocated services and existing / planned radio systems ?
Can one find realistically find contiguous bandwidth (e.g. 1 GHz) for 5G between 6 GHz and 31 GHz which can
be shared on a sustainable basis with other terrestrial services or space services?

10. Avanti - Confidential - Commercial in Confidence | 13 February, 2015 | 10
• Technology solutions for 5G / IMT mobile services are being developed in various
frequency bands above 31 GHz.
• Samsung has already tested 5G systems at circa 39 GHz. Field trials conducted “at
New York University and the University of Texas with funding from the US Army and
Samsung… found that 39 GHz mobile base stations can sustain 100 percent coverage
in cells with a 200-meter radius in high-density urban areas,” the FCC said. (from:
http://arstechnica.com/information-technology/2014/10/gigabit-cellular-networks-
could-happen-with-24ghz-spectrum-fcc-says/)
• Samsung has already tested 5G RLAN systems at circa 61 GHz. Samsung develops
60GHz WiFi capable of 4.6Gbps, will be in devices next year (from:
http://www.extremetech.com/computing/191872-samsung-develops-60ghz-wifi-
capable-of-4-6gbps-will-be-in-devices-next-year)
• Samsung developed 5G technology at 28 GHz can be modified to be viably used above
31 GHz for 5G.
What is the Reality - Technology Trials Show That 5G
Above 31 GHz Is Feasible

11. Avanti - Confidential - Commercial in Confidence | 13 February, 2015 | 11
 In Q3 2014 Ofcom asked what frequency bands, > 6 GHz, should be considered for 5G?
18 stakeholders responded. 9 mentioned no identification above 6GHz. 13 should be consider at WRC-15 but to protect the
FSS and existing services if above 6 GHz is considered.
Interestingly the Mobile operators did not have a strong opinion on this, but only equipment manufactures such as (Alcatel
Lucent and Samsung) supported the bands between 20-50GHz. Samsung mentioned their studies in 28 GHz
One UK MNO proposed to concentrate on blocks of free spectrum not used with FSS Services and identified 43.5- 47 GHz
Ofcom Consultation IMT Spectrum
Based on industry responses, likely block of free spectrum (not used by FSS Services) re as below.
37-39 GHz
42-47 GHz
57-64 GHz
70-80 GHz
Samsung is
already
looking at
38 GHz

12. Avanti - Confidential - Commercial in Confidence | 13 February, 2015 | 12
The study results
show that the High
priority bands
(i.e. > 31 GHz) are
more favourable for
5G from a regulatory
and technical view
point.

Why
Proposed Approach on 5G
:
Lose-Lose Win- Win
Spectrum to be identified for 5G
in relevant frequency bands
above 31 GHz
Spectrum to be identified for 5G in
frequency bands above 6 GHz
If a future WRC-2019 Agenda Item is agreed at WRC_2015, it should ensure any proposed 5G
terrestrial use is only in frequency bands above 31 GHz and not allocated on a co-primary
basis to satellite / space services.
More opportunities to accommodate 5G terrestrial
exist in higher mmWave frequencies above 31.0 GHz
Avoids detrimental effect to current and future
investments in satellite / space systems in bands
below 31 GHz worldwide.
