UK Flooded With Illegal Wireless
Posted: 08th Apr, 2004 By: MarkJ
Paul Munnery, managing director of Wireless CNP (read - has his own vested interests), has warned that many of the UKs 5.8GHz broadband wireless networks don't comply with Ofcoms spectrum restrictions:
When Ofcom made the 5.8GHz band available to use under a "light-licensing" regime in December 2003, it ruled that network equipment had to include dynamic frequency selection (DFS) technology to minimise interference with military radar, because the Ministry of Defence already used the band, and transmit power control (TPC) to ensure that a network transmitted at the lowest power level possible.
Munnery told the Wireless LAN Event in London on Tuesday that the companies using such networks without DFS and TPC could soon feel Ofcom's wrath. "Ofcom may be about to take to task some high-profile installations that haven't complied with these two features," Munnery said.
As other governments haven't insisted that 5.8GHz networks in their regions must use DFS and TPC, a lot of equipment is available that doesn't support it. This kit is available over the Internet and from some wireless vendors in the UK, and is often significantly cheaper than authorised devices that comply with British regulations.
In short, many networks could be running while being unaware of their error. However, Ofcom has previously expressed a desire to see the industry regulate itself (read - too lazy to do the job itself) on such matters. More @ ZDNet.
