Re: [WISPA] Using DECT phones to avoid interference issues.
Our panasonic system in the office does that. Seems to be the only one that does though. And trying to find a new handset to replace the one I left on top of the car has proven to be a bit of an issue There is clearly a good market for phones like this! I can't believe that no one is selling them. Heck, the USED panasonic phones for the 4000 series system go for almost as much as the brand new ones on ebay.

Re: [WISPA] Using DECT phones to avoid interference issues.
Marlon, What is the frequency of the phone system you speak of? Since this is a thread on DECT phones and you have never heard of DECT phones I am not sure your phone system would work to avoid the interference issues of the most common frequencies used for wireless networks. Some geographic areas are not as spectrally clean as your office seems to be if you are not running into any issues with interference. Please correct me if I am wrong. :-) The DECT phones are using licensed frequencies and are being used in the US legally. Regards, Dawn DiPietro On 3/24/07, Marlon K.

Re: [WISPA] Using DECT phones to avoid interference issues.
Understood Mine's 2.4. No problems with microwaves or to my wifi lan from it though. I like the idea of these new phones. I'd love to see something from them with the 4 line (better yet, 6) capabilities of my panasonic system. Before we bought the panasonic we tried to create the functional equivalent with * but without the ability to put people on hold and push a line button it was too cumbersome for us. (yes I know we could park a call, but that mechanism just didn't work for us.) marlon - Original Message - From: Dawn DiPietro [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Saturday, March 24, 2007 9:17 AM Subject: Re: [WISPA] Using DECT phones to avoid interference issues.

RE: [WISPA] Using DECT phones to avoid interference issues.
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!

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.

$50K up front and 50 cents a device to control an entire band in the US sounds like a pretty cheap deal to me. I am surprised nobody jumped on that.

Re: [WISPA] Using DECT phones to avoid interference issues.
Did you look at the UTAM URL? The fee until recently was $20 per device A market killer if I've ever seen one, especially when the manufacturing cost of a simple home phone is in that range! We'll see if this changes now that the UTAM prices have gone down. My thoughts is that the window of opportunity has long passed (there's no up front fee to continue making products only for the 900, 2.4, 5GHz UL bands that we wished they'd stop using). What exactly is a manufacturer's incentive to switch to 1.9GHz where there's a stiff UTAM fee? I used to work for a very, very, very large US manufacturer, and all UL business phone development in 1.9GHz have long ago (years ago) been permenantly cancelled to my best knowledge.

Do you have a link to the rules governing how this spectrum can be used, how it is licensed, who you have to pay what to use it, etc.? I would like to research this in more detail.

Re: [WISPA] Using DECT phones to avoid interference issues.
Check out www.utam.org. They really do a fairly good job of describing why they were created, what they did, and what companies desiring to use the cleared spectrum must do (pay). Whenever the topic of trying to understand the 1.9GHz spectrum that the FCC allocated for UL use, this is an important piece of the puzzle. It's simply not as simple as the FCC allocated spectrum for UL at 1.9GHz but nobody wanted to use it. I don't have a link for UPCS usage rules. I asked sources I trust (that worked on, but later abandoned UPCS product development). They tell me the usage rules are a minimal must listen before talking play-nice. That doesn't seem overly restrictive to me. - Original Message - From: John Scrivner To: WISPA General List Sent: Thursday, March 22, 2007 1:35 PM Subject: Re: [WISPA] Using DECT phones to avoid interference issues.
