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 providing > 1 Gbit/s speeds using: -‐ 4.5G / LTE standard
with carrier aggregation with IMT bands below 3.4 GHz and at 3.5 GHz.
-‐ also LAA
3G / 4G / 4.5G devices already have 2.4 GHz / 5 GHz WIFI radios for
enabling low cost data off-‐load service delivery.
Circa 70 – 90 % of mobile data traffic is carried by WIFI networks today.
MNOs top priority seems to be to: -‐ monetise their huge 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 basisin cm wave bands below 3.8 GHz in Europe supported by WIFI and WIGIG.

Vodafone Germany launches 4.5G services at up to 375 MbpsSunday 18 September 2016 | 20:59 CET | News Vodafone Germany has announced the launch of 4.5G mobile technology, supporting speeds of up to 375 Mbps. The new technology will be rolled out in 30 cities across the country by end-‐2016, with new 4.5G base stations now live in 22 of these cities. These include the centres of Berlin, Dresden, Duesseldorf, Cologne, Frankfurt, Hamburg and Hanover. Vodafone deploys triple carrier aggregation in 800, 1800 and 2600 MHz bands. https://www.telecompaper.com/news/vodafone-‐germany-‐launches-‐45g-‐services-‐at-‐up-‐to-‐375-‐mbps-‐-‐1162788
TIM launches 500 Mbps 4.5G service in 3 Italian citiesThursday 15 December 2016 | 15:00 CET | News Telecom Italia (TIM) has claimed a European first with the launch of a commercial service offering download speeds of up to 500 Mbps using 4.5G technology. The service is already active in Rome, Palermo and Sanremo and can be accessed with the new Sony Xperia XZ smartphone, available to TIM's business and retail customers as an exclusive. The higher speeds are achieved via carrier aggregation, with TIM bundling spectrum from the 800 MHz, 1800 MHz and 2600 MHz bands, as well as the so-‐called L band (1500 MHz),and increasing spectral efficiency by evolving antenna transmission systems.https://www.telecompaper.com/news/tim-‐launches-‐500-‐mbps-‐45g-‐service-‐in-‐3-‐italian-‐cities-‐-‐1176363

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.
Rapidly increasing population of Fixed Service links (used usually for backhaul).
Radical increase in Ka-‐band services via GEO and Non-‐GEO satellite systems (Note: No satellite systems in 31.8 – 33.4 GHz).
Fragmentation of spectrum for possible 5G/IMT-‐2020 use due to the above.
Challenges for For 5G/IMT in ‘Low mmwave’ Bands
So why plan / implement / invest in 5G/IMT in ‘Low mmwave bands’ ?
Political reasons (‘industrial leadership’ ?) are a poor substitute for economic rationales.

-‐ 3G / 4G / 4.5G devices will in 2017 onwards have 60 GHz WIGIG radios for enabling very high data (~ 10 Gbit/sec) off-‐load service delivery.
-‐ In 2017, ~ 200 million 60 GHz WIGIG radio forecast to be shipped.
-‐ By 2020, over 1 billion 60 GHz WIGIG radios projected to be shipped.
-‐ 5G should benefit from the leverage of technology and product developments in WIGIG.
-‐ Radio / device technology used for 60 GHz WIGIG can be efficiently reused to develop ‘high mmwaveband’ (viz > 66 GHz ) 5G / IMT-‐2020 systems.
-‐ Up to 15 GHz available for 5G/IMT with minimum of 5 GHz contiguous blocks at 66 – 76 GHz & 81 – 86 GHz.
-‐ > 66 GHz 5G/IMT will also offer very high data rate (> 10 Gbit/sec) services.
Future 5G device in EU will be multi-‐band-‐radios supporting
-‐ LTE/4.5G in bands below 3.8 GHz for wide area coverage / outdoor use / indoor use.
-‐ 4.5G or 5G in bands above 31 GHz for high capacity / indoor / near-‐indoor use
-‐ 2.4 / 5 GHz WIFI, 60 GHz WIGIG and > 66 GHz 5G.
