Vodafone and Huawei conducted a successful 5G trial using 70 GHz spectrum, achieving download speeds of over 20 Gbps. This demonstrated the potential of high mmWave bands for delivering extremely high individual link performance for backhaul or in small, dense areas like stadiums. The vision is for a commercially and technically viable 5G/IMT-2020 ecosystem that utilizes a variety of spectrum bands, including low bands below 3.6 GHz for coverage, high mmWave bands above 66 GHz for very high data rates, and unlicensed bands for traffic offloading. Satellite networks can also complement terrestrial solutions by providing ubiquitous coverage.

• 36 GHz of spectrum identified as candidate
bands for further studies for 5G/IMT.
• Sufficient spectrum from which to find
additional spectrum for IMT/mobile/5G
• Important to consider ONLY these bands,
which were identified on the basis of global
consensus at WRC-2015.
• Global harmonization of spectrum is key to
the development of wireless
telecommunications

Challenges for 5G/IMT in ‘Low mmWave’ Bands
Technical Challenges For 5G/IMT:
- Severe radio-link implementation
challenges due to very high
attenuation by building walls,
window glass, etc.
- Is it practicable to reliably establish
5G/IMT with outdoor-indoor
coverage ?
- Significant cost to deploy robust
wide area 5G/IMT networks to
provide reliable 5G services for
outdoor and indoor coverage.
Spectrum Challenges For 5G/IMT:
- Constraints for 5G/IMT due to existing /
planned use by other terrestrial and
space/satellite services.
- Increasing population of Fixed Service
links (used usually for backhaul).
- Radical increase in Ka-band services via
GEO and Non-GEO satellite systems.
- Fragmentation of spectrum for possible
5G/IMT-2020 use due to the above.
So why plan / implement / invest in 5G/IMT in ‘Low mmWave’ bands ?

Opportunities for 5G/IMT in ‘High mmWave’ Bands
High mmWave Bands opportunities:
- Up to 15 GHz available for 5G/IMT
with minimum of 5 GHz contiguous
blocks at 66 – 76 GHz & 81 – 86
GHz.
- Very wide carriers and high capacity
- Not heavily used by incumbents.
- High prospects of international
harmonisation – support from all
regional groups at the WRC-15
- WIGIg technology is currently being
deployed at ~ 60 GHz.
- 4G devices will in the near future
have 60 GHz WIGIg radios for
enabling very high data (~ 10 Gbps)
off-load service delivery.
- In 2017, ~ 200 million/ ~ 1 billion,
60 GHz WIGIg radio forecast to be
shipped by 2017 / 2020.
- Radio / device technology for 60
GHz WIGIg could be reused to
develop ‘high mmWave’ band ( > 66
GHz ) 5G / IMT-2020 systems.

Vodafone, Huawei reach 20 Gbps speed in 5G trial
19 JUL 2016
Vodafone and Huawei completed a 70 GHz 5G field test in Newbury, UK,
reaching data rates of more than 20Gb/s, and supporting multiple users at 10
Gb/s each. This demonstrated the possibility of delivering an “extremely high
level” of performance for an individual link, such as backhauling data between
two locations, or supporting a large number of connections in small areas,
explained David Lister, 5G research manager, Vodafone Group. He said that
bands above 24GHz is where 5G will deliver the highest data rates and 70
GHz in particular can increase range, performance and capacity.

Satellites will Play a Role in the 5G Ecosystem
High Throughput Satellites (HTS) have reduced the
communication costs significantly
Satellite can usefully complement
terrestrial solutions for a large
number of heterogeneous use cases:
• Ubiquitous coverage
• High speed networks
• Standby and overspill
Satellite networks are better suited for specific
verticals targeted by 5G than terrestrial only solutions,
including:
• Highly secure enterprise networks
• Highly distributed small/medium size networks
• Content distribution
• Dispersed M2M networks

4G / 4.5G LTE Networks
• 4G / 4.5G LTE Networks are already demonstrating ~ 0.5 Gbit/s speed using 4.5G /
LTE standard with carrier aggregation using IMT bands up to 2.6 GHz.
• 4.5 LTE Networks will in near future provide > 1 Gbit/s speeds using 4.5G / LTE
standard with carrier aggregation with IMT bands below 3.4 GHz and at 3.4 – 3.6
GHz in ITU R1/R3.
• Current devices already have 2.4 GHz / 5 GHz Wi-Fi radios to enable low cost data
off-load service delivery. Circa 70 – 90 % of mobile data traffic is carried by Wi-Fi
networks today.
MNOs top priority seems to be to:
• Monetise their investments in 3G / 4G / 4.5 G networks.
• Achieve economically viable deployment of new ‘5G-like’ networks / services.
It is highly probable that 5G/IMT-2020 networks will be deployed on large scale basis
in cmWave bands supported by Wi-Fi and WIGIg
