Nokia Commits to Push To Talk With New Phone
By Eric Lin, Wed Nov 12 20:15:00 GMT 2003

Today Nokia announced a new ruggedized GSM handset with walkie talkie (push to talk) technology built in. Because the handset is ruggedized, it seems to designed to compete with so many of the iDen phones found on today's construction sites. However Nokia has included a host of extras for the outdoor sports enthusiast, either missing the mark, or combining two rugged use markets for one handset.

The 5140 is host to a number of modern features like EDGE and a VGA camera, plus it adds interesting features for the active user (Mobile Burn has full specs and pictures.), but it's the inclusion of PTT technology that has people talking. Nokia's Push to Talk technology is half-duplex, just as Motorola's iDen and other current candidates. They claim that thanks to the use of GPRS and EDGE that the latency is competitive with other leading systems. No mention is made of what technology is being used, nor if the feature is carrier dependent.

One walkie talkie phone isn't much, but included in the press release is an announcement that Nokia intends to release a number of phones, including smartphones with push to talk throughout 2004, and that all of their GSM handsets will include it by 2005. PTT has generated quite a buzz this year, but until now it just seemed like hype. A commitment lends credence to all the claims that this is the next big thing, or at least one of the next big things.
