NEWS These devices could dominate the broadcast media that existing mobile phone carriers hope will draw users to UMTS services. Many of the leading handset suppliers are hedging their bets by developing both technologies. Access to the growing number of digital radio stations is currently restricted to internet, digital TV or PC devices such as Psion's Wavefinder, which has prompted criticism that the medium lacks mass-market appeal. However, silicon.com has learned that mobile handset manufacturers such as Sony and Nokia are set to develop the next generation of portable radio devices that will combine GSM messaging and data functions. One source told silicon.com that Sony's product could be out as early as September. It is expected to combine a digital radio broadcasting receiver with colour LCD screen to display animation and other kinds of data content and GSM connectivity through which a user would be able to request programmes or information. But Sony is not alone, another source revealed: "All the big players are racing to get their products out and Nokia is among them." Other functionality being developed includes having a memory chip in the device that would enable users to store encrypted programmes. The potential failings of such a device rest on battery life and cost. However, silicon.com has learned that Sony is to install digital signal processor technology from UK software company RadioScape, which it claims will reduce the cost and power consumption of receiving digital audio and data. This means Sony could offer the product at a price low enough to entice the consumer market. If successful, the devices and the available content could provide an alternative to the services anticipated on third generation mobile phones according to Matthew Honey, managing director of Unique Interactive, part of the UBC Media group that owns digital radio channels Digizone and Oneword. He said: "These devices will be vital to the mass take up of digital radio. People consume radio on the move more naturally than TV."
