There's a reason you haven't seen these products here. I began searching for why the last time a thread discussed the 1.9GHz UL band surfaced on this list. I doubt you'll ever see much product ever emerge for this band in the United States. There's a reason for this too ... I've heard some discussion on this list regarding how "the FCC gave the industry UL spectrum and they didn't use it." With such a connection, wisps must understand why this band has been underutilized here (as well as judging the chances of new products emerging). Years ago the FCC took this band away from Pt-Pt microwave users. They authorized a group called UTAM to pay what was necessary to move these microwave users to clear the band. Apparently UTAM spent "whatever it took" since it wasn't there money. Manufacturers wanting to field UL product had to pay UTAM what were known as "clearing fees". Check out http://www.utam.org/ClearingFees.html. Prior to April 1 2005 the clearing fees were enough to dissuade any manufacturer from building UL product for the United States! IMHO the UTAM fees doubled the cost of producing UL product. Since April 1 2005 the fees drop to a mere 50 cents per radio, but a manufacturer must still pay UTAM $50,000 up front. With the lack of products, UTAM has amassed a huge debt. The FCC groundrules for clearing the Pt-Pt users from the band were more than enough to insure that this UL band would never be effectively utilized in the United States.

I deployed a DECT (Digital European Cordless Telecommunications) system with 450 handsets several years ago. The phones were single line units made by Phillips. They system worked OK, but the features were very lacking. The frequency range was 1880-1900 MHz This deployment was in Paris, France and was connected behind a PBX. There were about 21 "base stations", each one capable of supporting many conversations. The DECT system is interesting because it is the standard in Europe and people's home handsets could be registered on this system. All I had to do was enter the code # into the management system. We were afraid that the handsets might begin disappearing due to the interoperability, but these handsets were so cheesy that the home models were much better. The DECT system did handoff calls as the users walked between base stations, which was pretty cool. A year or so aqo, DECT was authorized here in the US, on slightly different frequencies: 1920-1930 MHz. There was not any general hoopla at all around this introduction. DECT isn't GSM, but the two are made to be very compatible and in Europe, there are dual mode DECT/GSM phones. These systems, which are sometimes used in installations like mine, allow the user to switch over to a more cost-effective DECT connection when in range, and the GSM signaling is passed over to the DECT system, but in DECT format. I haven't seen but one DECT phone here and it was very basic, but I expect that the technology will quickly be expanded to products like the multi handset systems, etc that are getting popular from Uniden and all the others. It should eliminate all WISP interference for sure!

All, I am sure some of you have already thought of this but I would suggest a great alternative to avoid interference with the most common frequencies used to deploy wireless networks would be to use DECT cordless phones in the house. They use the 1.9Ghz frequency and are relatively inexpensive. We use a DECT phone system here with all the features we could ever ask for and we got them for a song after the rebate. Just a thought.
