With just the push of a button, Nokia 5140 phone owners can connect by using the push-to-talk feature for quick voice communications. The push-to-talk feature can be used to connect the user to one person, or to a group of people.
The Nokia 5140 is the first GSM push-to-talk handset. Along with its ability to quickly connect users at the push of a button, the Nokia 5140 phone also includes a number of unique features designed for the active-minded consumer such as a digital compass, Fitness Coach application and a built-in VGA camera. The GSM/GPRS/EDGE Nokia 5140 phone 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.
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 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. This "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 on average is comparable to that of existing dedicated push-to-talk cellular networks.
The Nokia 5140 phone features a durable dust, bump and splash-resistant housing that allows it to keep up with demanding users, but its active nature is more than just skin deep. To keep users oriented on the trail, an integrated digital compass displays the direction both graphically and numerically. After dark, a built-in flashlight helps to guide the way. For the fitness enthusiast, 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 to help make that time go by even faster. An optional Active Headset enhancement is available to provide easier 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.
