Worldwide regulations for 60GHz – Outdoor Fixed Links

European Regulations (60 GHz) • The 60GHz band is typically licence-exempt in Europe due to the

high oxygen absorption in this band. The 60GHz band in Europe refers to frequencies from 57 – 64GHz

• Spectrum was ‘allocated’ by recommendations by ECC*– V Band ECC/REC (09)01

• USE OF THE 57 - 64 GHz FREQUENCY BAND FOR POINT-TO-POINT FIXED WIRELESS SYSTEMs

• Local Regulators are thereby assured by the ECC/RECs that – ECC has considered interference issues with Pan European

services– Allowing FS operation is low risk unless there are specific,

existing, in-country frequency allocations that need to be considered

– The channel allocation scheme is suggested for use only if a regulator wishes to coordinate links in the band, and is not mandatory

*Electronic Communications Committee (ECC) within the European Conference of Postal and Telecommunications Administrations (CEPT)

Ofcom Executive Summary - Release of the 59 – 64 GHz band, December 2009

– This statement (document IR2078) presents Ofcom’s decision to go ahead with opening the spectrum in the 59 – 64 GHz band for Fixed Wireless Systems (FWS) and to combine this with the existing 57 – 59 GHz band under one overall licence exempt authorisation approach for FWS

• Ofcom (UK regulator) does not require any minimum coordination dist @ 60GHz• Even at max 316W EIRP, boresight interference distance = 2.5km for @ 60GHz• Radios in 18GHz – 38GHz bands would need to reduce EIRP to 16mW to achieve

the same 2.5km interference distance

• Effective interference power: 316W @ 60GHz equiv. to only 11mW @ 18GHz• Interference Minimal in 60GHz band

Ao

V-band deployments without interference

• Minimum distance for zero measurable signal = 50cm (co-polar).• Narrow antenna beamwidth allows to mix Tx Hi and Tx Lo for parallel links• (4+0) possible on same channel• Interference Minimal in 60GHz band

60 GHz Applications

Why Licence-free V-Band

• Band suffers from high Oxygen absorption– Severely limits link range to 1km or less– Difficult to Intercept– Massive benefits in low interference and frequency reuse:

• Ideal for small cell backhaul and no need to coordinate
