DataTAC

DataTAC is a wireless data network technology originally developed by Mobile Data International which was later acquired by

), where public end-to-end data services are provided for enterprises, FedEx, and consumer mobile information services were also offered called MobileQuotes with financial information, news, telebetting and stock data.

DataTAC is an open standard for point to point wireless data communications, similar to

850 and 857 also used the DataTAC network.

In North America, DataTAC is typically deployed in the 800 MHz band. DataTAC was also deployed in the same band by Telecom Australia (now Telstra).

The DataTAC network runs at speeds up to 19.2 kbit/s, which is not sufficient to handle most of the wireless data applications available today. The network runs 25 kHz channels in the 800 MHz frequency bands. Due to the lower frequency bands that DataTAC uses, in-building coverage is typically better than with newer, higher frequency networks.

In the 1990s a DataTAC network operators group was put together by Motorola called Worldwide Wireless Data Networks Operators Group (WWDNOG) chaired by Shahram Mehraban, Motorola's DataTAC system product manager.
