Date: Mon, 31 Jan 2011 16:13:07 +0000 MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Message-Id: <201101311613.07381.david.goodenough@btconnect.com> Sender: linux-wireless-owner@vger.kernel.org List-ID: In the UK Ofcom (our regulator) has designated a portion of spectrum at 5.8GHz for use outdoors, with 4W EIRP and requiring DFS, on payment of an annual fee of GBP 1.00 per client/access-point (to a minimum of GBP 50.00). With the standard GB regulatory db entry this is excluded. How do I add this (had anyone already done this) and how to I restrict the DFS code to remain within this range rather than using any of the other channels that require DFS? The GB regulatory domain database entry normally reads:- country GB: (2402 - 2482 @ 40), (N/A, 20) (5170 - 5250 @ 40), (N/A, 20) (5250 - 5330 @ 40), (N/A, 20), DFS (5490 - 5710 @ 40), (N/A, 27), DFS BTW I notice that in some countries some frequencies are marked NO_OUTDOOR but the 5.1, 5.2 and 5.4 bands are not marked NO_OUTDOOR for GB. Is there a reason for this? >>From the relevant Ofcom document for the 5.8 GHz band (http://stakeholders.ofcom.org.uk/binaries/spectrum/spectrum-policy- area/spectrum-management/research-guidelines-tech-info/interface- requirements/uk_interface_2007.pdf page 6) we find:- Table 3.1: Minimum requirements for the use of: - Fixed Broadband Radio Systems operating in the 5725 - 5850 MHz band (Band C) Mandatory (1-9) 1 Frequency band 5725 MHz to 5850 MHz 2 Radio service Fixed 3 Application Fixed Wireless Access 4 Channelling modulation N/A 5 Maximum transmit power Maximum mean e.i.r.p. of 4W limit Maximum mean e.i.r.p. density of 23dBm/MHz 6 Channel occupation rules N/A 7 Duplex type/separation TDD 8 Licensing Regime A licence is required 9 Additional essential N/A requirements Informative (10-13) 10 Frequency planning DFS and TPC is assumed to be implemented as assumptions specified in ETSI harmonised European standard EN 302 502 11 Reference EN 302 502 12 Remarks N/A 13 EU Notification Number 2006/422/UK NOTE The frequency range 5795-5815 MHz shall not be used and should be notched out to protect RTTT devices So that would appear to require two extra lines:- (5725 - 5795 @ 40), (N/A, 27), DFS (5815 - 5850 @ 40), (N/A, 27), DFS But these two lines have to be available for DFS hopping, and the two indoor bands in the regular GB spec have to be excluded. How is this achieved? Or do I have to have a David
