Tom/Charles The whole objective is to increase the effective use of spectrum under the existing rules. NO WAIVERS, NO RULE CHANGES and NO INCREASED INTERFERENCE.
To maintain the existing frequency coordination efficiencies "the path" antennas must meet CAT A (or B) and their size will be large. It is the "wasted" side lobe radiation that can be put to productive use with subordinated paths where the radiation from the Distributed Radiating Elements (DREs) at the input to any victim receiver is always below the coordinated interference or 6dB below the victim receiver's thermal noise. The size shape etc of the DRE can be any size or shape (small) providing all the network criteria is satisfied.

I HIGHLY support NOT lowering the antenna size requirement for 11Ghz, as anything smaller than its at today, just compromises long haul backhaul applications, in which WISPs do not have many option for long haul. At 8-10 miles, a couple extra Degrees of beamwidth is capable of interfering with a much wide length of area in the city effected. Although, I'd like to see 6Ghz lowered to 4 ft dishes. There isn't a landlord in their right mind that would allow a 6 ft antenna installed on their roof. Or maybe a nicely designed 3 ft model, possibly acceptable. Not that I'm not for concurrent coordination.

The SIA is all over Fibertower's 2' request in 11 GHz...imagine 4 GHz, which could knock out a lot of C-band downlinks (now, not being a satellite expert, I'm not sure of the current usage of this channel, but being that the SIA has tons of $$$$, I'm sure they'll raise up a storm) That said, I think you need to get the antenna beamwidth requirements waives / relaxed first...even if concurrent coordination passes, I don't think anyone will want to be installing 6' dishes on people's houses... -Charles ------------------------------------------- WiNOG Wireless Roadshows Coming to a City Near You http://www.winog.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of michael mulcay Sent: Saturday, June 30, 2007 11:09 AM To: 'WISPA General List' Subject: RE: [WISPA] FCC Public Notice Charles, The request for a declaratory ruling applies to all frequency bands. The bands of immediate interest are 3.7 to 4.2GHz and 5.9 to 6.4GHz (an easy freq change for WiMax, 3.5GHz to 4GHz band and 5.8GHz to 6GHz band)where the subordinated link antenna sizes drop from 8ft and 6ft to as low as 1ft flat panel.

The amount of microwave spectrum is finite and it is in everyone's interest to seek ways to increase the effective use the existing spectrum. Unfortunately, there may be those who have a vested interest in maintaining the status quo and who will attempt to stifle innovation. Innovation is one of the few ways that small companies can compete with large established companies and that is why we believe this is a one time opportunity for WISPs to join the big league as regards the ability to obtain licensed spectrum which can support low cost 802.16-based (WiMax) equipment with small antenna elements to provide licensed backhaul and broadband services to hundreds of additional subscribers, through frequency reuse without causing any additional harmful interference. It would be a great help if WISPA as a group and individual WISPs file comments in support of the request for a declaratory ruling, especially as there is everything to gain and nothing to lose. The Comment deadline is July 19, 2007. Comments can be filed via the FCC's ECFS or by regular mail. Details are on the FCC's web site. Thanks in advance, Mike 1.
