Real-Time Two Way Communication More than DoubleSpeak

I had to read the press release more than once to make sense of ABI Research’s latest prognostications about the growth of the LBS market and its use of "real-time two-way" (RTTW) communication for navigation systems. Boiled down to simple terms, RTTW means having two communication system on one device. The first might be the GPS receiver to support navigation; the second a celluar radio to receive traffic information. Regardless of the form, the result is predicted to be explosive growth. From the release, "Handset-based navigation, where the navigation processing is conducted off-board (not on the handset) is one form of RTTW connected navigation, and it will experience explosive growth. Off-board navigation will go from under half a million users worldwide at the end of 2006 to more than 70 million at the end of 2012."
