techUK UK Spectrum Policy Forum: Cluster 2 ‘mmWave’

2. 1
Areas Covered
• mmWave Spectrum
• FWS Use
• mmWave (>50GHz) FWS Bands available in the UK
• 60 GHz (‘V-Band’) – UK
• 70 / 80 GHz (‘E-Band’) – UK
• Activities in CEPT / ITU-R on mmWave for FWS
• New Work Items for WRC-19
• National discussions on FWS

3. mmWave Spectrum
2
Within the wireless backhaul / infrastructure communities ‘mmWave’ is generally referred
to as meaning the bands above 50GHz.
Frequency ~Wavelength
10 GHz 30 mm
30 GHz 10 mm
50 GHz 6 mm
300 GHz 1 mm

4. 3
Fixed Wireless Systems Use
• Used for a wide range of different applications across a range of bands from 1.4 GHz to
86GHz:
– Trunking and long haul connections (lower traditional ‘microwave’ bands)
– Wireless backhaul for mobile broadband
– Wireless infrastructure for a range of services including the Utilities, emergency
services, broadcasters, CCTV for local authorities and more recently for the financial
sector which leverage the low latency benefits of wireless fixed links.
Majority of links in UK are used to
provide wireless backhaul for mobile
networks.

• Licence Exempt – Fixed Links (IR 2078)
• Full ‘V band’ 57.1 – 63.9 GHz available in UK since 2010
• Main technical parameters align with CEPT ECC Rec (09)01

the 59 – 63.9GHz band.

7. 70 / 80GHz (‘E-Band’) - UK
6
Band first made available in the UK in 2007; Reviewed and restructured in 2013. Now available as:
• Ofcom coordinated approach: 2 x 2 GHz
• Self coordinated approach: 2 x 2.5 GHz

Technical Conditions IR 2000*
Frequency Band(s) As above
Max Tx Power 0dBW
Max EIRP 55dBW
Min Antenna Gain (see ETSI EN 302-217) 38dBi
* See IR 2000 and Ofcom OFW 446 for full details of the technical assignment criteria / conditions.

8. 70 / 80GHz (‘E-Band’) – UK Use
7
• Now seeing significant increasing use of ‘E Band’
• In less than 3 years the number of registrations in the Self Co-ordinated part of the
band has quadrupled from around just fewer than 500 links to now over 2,000 links.
E-Band ‘Self Co-ordinated’ Links
Due to the short hop, high capacity
nature of these links the majority of
deployments are concentrated
around cities and urban areas as
shown in the figure opposite.

9. Activities in CEPT / ITU-R on mmWave for FWS
8
• Revision of CEPT ECC Report 173 (Fixed Service in Europe Report) to include new
information on bands above 50 GHz.
• New study items now underway in CEPT for the ‘W’ and ‘D’ bands:
‘W Band’ Studies ‘D Band’ Studies
92 – 94 GHz 130 – 134 GHz
94.1 – 95 GHz 141 – 148.5 GHz
95 – 100 GHz 151.5 – 164 GHz
102 – 109.5 GHz 167 – 174.7 GHz
111.8 – 114.5 GHz
• New ITU-R Report being developed on the use of the FS for IMT backhaul

10. New Work Items for WRC-19
9
• WRC-19 agenda item 1.15
Identification of frequency bands for use by land mobile and fixed services applications
in the frequency range 275 - 450 GHz.
• Current international regulations allocations table covers up to 275GHz
– A number of bands within the range 275 – 1000GHz are identified for use for passive
services
– This agenda item aims to study identification of bands within the range 275 –
450GHz for fixed and land mobile services and associated sharing and compatibility
issues

11. New Work Items for WRC-19 Continued…
10
• WRC-19 Agenda Item 1.13
The following bands to be studied for IMT identification:
 24.25-27.5 GHz
 37-40.5 GHz
 42.5-43.5 GHz
 45.5-47 GHz
 47.2-50.2 GHz
 50.4-52.6 GHz
 66-76 GHz
 81-86 GHz
The following bands to be studied for new mobile service allocations and IMT
identifications:
 31.8-33.4 GHz, 40.5-42.5 GHz and 47-47.2 GHz.

UK National Discussions – Matters related to FWS
• Ofcom holds Fixed Wireless Industry Liaison Forum meetings (FWILF) usually held
twice a year.
• FWILF meeting is designed to aid direct communication with Industry, provide updates
on Ofcom policy and discuss new ideas / concepts.
