Nokia shows first GSM push-to-talk phoneBy Jørgen Sundgot, Wednesday 12 November 2003
The world first Nokia 5140 lets users push a button to talk over data networks, features a built-in compass, a fitness coach application, integrated camera and much more.

Nokia today unveiled the world's first GSM push-to-talk handset, the sports-inspired Nokia 5140 phone. Along with its ability to connect users at the push of a button, the Nokia 5140 phone also includes a number of unique features designed for active-minded users such as a digital compass, Fitness Coach application and a built-in VGA camera.

The Nokia 5140 is the world's first GSM push-to-talk handset
A GSM/GPRS/EDGE phone, the Nokia 5140 will be available in a GSM 900/1800/1900 MHz version primarily for the Europe/Asia market and in a GSM 850/1900/1800 MHz version primarily for the Americas market. Both versions are expected to be available during the 2nd quarter of 2004.

With the push of a button, Nokia 5140 phone owners can connect to friends and family by using the push-to-talk feature for quick voice communications, or to access the built in VGA camera. The push-to-talk feature can be used to quickly connect the user to one person, or to a group of people by using a key mounted on the side of the handset.

While the Nokia 5140 phone is the first Nokia GSM handset to feature push-to-talk capability, it marks the first step as push-to-talk becomes an increasingly common function. During 2004, Nokia said it will introduce a full range of push-to-talk capable GSM phones, including Symbian OS based smartphones. From 2005 onwards push-to-talk will become available for all Nokia GPRS/WCDMA phones. The "walkie-talkie" style push-to-talk feature of the Nokia 5140 phone is a half-duplex voice over IP (VoIP) solution using the existing GPRS and EDGE data networks that are part of current GSM systems. This method results in performance that according to Nokia is on acerage comparable to that of existing dedicated push-to-talk cellular networks, common in the U.S.

The Nokia 5140 phone also features a dust, bump and splash-resistant housing, as well as an integrated digital compass which displays directions both graphically and numerically. A built-in flashlight helps guide the way, and for fitness enthusiasts, a new Fitness Coach feature uses training regimens based on professionally recommended training principles.

Additional functionality of interest to the fitness minded is an interval timer and stopwatch for keeping track of workout routines and an integrated FM radio. An optional Active Headset enhancement is available to provide wearability while on the move, and for increased resistance to bumps and splashes. The Active Headset features one button to answer and end calls and another that can be used to activate the push-to-talk capability of the Nokia 5140 phone.

The Nokia 5140 phone also supports downloadable polyphonic ring tones, custom wallpapers and J2ME applications to customize the handset. For additional personalization, optional Xpress-on shells are available in three colour combination schemes.

An additional hi-res picture of the Nokia 5140 is available on the following page.
