Could you steer me to the web site? I know Ameritech has a program that you have a wireless phone in your business campus and when you leave it becomes a full cellular. Isn't that correct Mr. Lurgio?

QC has had an indoor antenna system for using cabled CDMa within buildings for many years. the way that CDMA works, this is a very simple set of delay and antenna pods which go down a hallway off the single basestation antenna input. the RF thinks that each delay is just like a cell station to cell station delay and treats it like that, so each 100 foot or so is an antenna with microwatts of power and the phone hands off going down the hall. allows the Rf pattern to be adjusted real close to the shape of the building. What this does is allow a single basestation string to serve a while floor of an office building. Add another string if you have more users. since each one can be made OTHOGONAL (8^)...had to use it..) to the others, then you can stack up alot of them close to each other. with all the 3G systems coming along, then you can imagine alot of ways to use this type of thing for CDMA networks.
