TI explores a new EDGE

Texas Instruments (TI) has embraced EDGE (Enhanced Data Rates for GSM Evolution) technology as part of its plans to supply technology for 3G wireless networks.

TI's TCS3500 is its first chipset for EDGE and is intended to allow mobile phone designers to build smart phones and personal digital assistants running on EDGE networks. EDGE networks are the next step in the evolution of GSM-based digital communications and from a bridge between GPRS and true-3G telecoms networks. Such networks are intended to support wireless data rates and bandwidth that supersedes those from GPRS networks. This opens up new ranges of applications that EDGE devices could support, most notably streaming video.

TI says that devices using its chipset will support up to three times the data rate throughput of current GSM/GPRS devices. The TCS3500 is anchored by the OMAP850, a high-performance applications processor integrated with a quad-band EDGE modem. The OMAP850 processor will support multimedia and camera capabilities up to 2.0 mega pixels.

The OMAP850 processor's modem functionality is based upon TI´s established GSM/GPRS technology, with further enhancements to support the higher EDGE data rates. The OMAP850 will have design that allows scalability of a single platform to address all handset segments targeting data services encompassing mid-range feature phones, smart phones, and multimedia rich wireless PDAs and other handheld devices.
