  1. Worldwide regulations for 60GHz – Outdoor Fixed Links Darko Beverin darko@tagsa.co.za 29 May 2014

  2. 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)

  3. 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

  4. Worldwide regulations for 60GHz – Outdoor Fixed Links Europe: ECC/REC/(09)01 USA: FCC Part 15.255 • No channel assignments required in 60GHz band

  5. Licencing of 60GHz (V) Band • Mostly licence-exempt

  6. Licencing of 60GHz (V) Band CDW Hutton Tessco Winncom Cernet license-exempt or light-license

  7. Coordination Distances • 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

  8. V-band deployments without interference A +45o A -45o B +45o B -45o • Minimum distance for zero measurable signal = 50cm (co-polar). • Narrow antenna beamwidthallows to mix Tx Hi and Tx Lo for parallel links • (4+0) possible on same channel • Interference Minimal in 60GHz band Ao

  9. 60 GHz Applications Operator A Operator B Small cell

  10. 60 GHz Applications

  11. 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
