MP3.com is expanding its business with a move into the digital-device arena.

The company is to work with wireless-technology developer Qualcomm to develop an application for the delivery of digital music.

Current technology for portable MP3 players requires that users upload digital music-files from a computer, or from a device connected to the Internet.

MP3.com intends to use Qualcomm's Binary Runtime Environment for Wireless (BREW) applications to produce software enabling a portable device to download music from a cellular connection.

A device capable of a wireless music-download would be more like a radio than a CD player, and may rid portable players of some of their more expensive components. MP3 players tend to need large quantities of Flash memory or a hard drive to hold a suitable number of songs.
