I have a Telular SX5T single band wireless modem/TNC for sale. It is also GPS capable and has a GPS antenna and all hookups included. Here is what I got from the website:
The SX5T-515C (Sprint approved) Terminal is Telular Corporationís second generation solution for digital fixed cellular communications. Utilizing the CDMA 2000 1XRTT cellular network, the SX5T-515C Fixed Wireless Terminal provides exceptional voice quality, analog fax (Sprint may not support FAX on their network), packet data, circuit-switched data, and PC fax.
It can be utilized in a number of different applications including wireline replacement, portable dial tone, least cost routing, and telemetry. The Telular SX5T-515C Fixed Cellular Terminal operates on the 1900 MHz frequency band and can provide access to the Internet and email at rates as high as 144 Kbps.
This thing is brand new in the box. First $60 takes it, PayPal ok. Email me for pictures.
