We meet again.

Omnitracks uses a European partner. e-Qcom is just Qualcomm.

Snaptrack has a revolutionary way of getting a GPS fix on a handset in less than a minute, even indoors without more upgrades to base stations trying to triangulate and get a wrong answer due to terrain. (impossible to triangulate with contact to less than three base station transceivers in contact with the handset.)

SnapTrack can be added to any kind of phone or subscriber box regardless of air interface.

HDR is a (base-station to subscriber) link able to be added to GSM infastructure to use isolated channels in their spectrum(where the real investment is). You can use TDMA or GPRS to send data back to the base station switch. Right now, Q is demonstrating HDR using 1XRTT as about 300kb/sec reverse link back from the subscriber.

1XRTT is an air-interface that can use GSM-MAP and coexist on the same GSM provider switch. But a new phone must be developed having a sim card and the right software. The advantage is improved spectral efficiency of CDMAOne. But, CDMA traffic must be kept in isolated channels from TDMA.

HDR, 1XRTT, GPRS, EDGE and WCDMA are air2air interfaces that can be deployed anywhere PROVIDED they are properly added to the incumbent switch-management language. IS95, AMPS, and IS136/TDMA uses IS41 as the language. GSM uses MAP.

You have to be specific when discussing GSM. You must differentiate between the TDMA-based air-air interface and the GSM-MAP control protocol used to manage the voice traffic.

Qualcomm and Vodaphone demonstrated the ability to drop in a CDMAOne-speaking base station transceiver on an existing Base station manager about two years ago. They converted a second-generation Q-handset to use the GSM-MAP protocol by adding a sim card reader and licensing GSM handset software off the shelf.
