GSS Debuts Integrated FM Radio and Cell Phones

Las Vegas - Apr 20, 2009 - Global Security Systems (GSS) has debuted FM radio data chips plus RBDS-based protocol for cell phones and consumer electronics. GSS partnered with mixed-signal developer Silicon Laboratories for more than three years to develop government and commercial FM-based message distribution systems and receiver chip designs supporting the Radio Broadcast Data Service (RBDS) aspects of FM broadcasting. The integrated technologies provide cell phone users with FM listening, and add state and federal emergency messaging via the FM broadcast infrastructure.
Silicon Labs' embedded FM antenna technology further enhances the system by allowing the FM receiver to use internal antennas inside the mobile device instead of requiring plugged-in headphone wires. This allows mobile devices to remain constantly connected to the FM alerting system, while capitalizing on power-saving mechanisms to consume very little current. In addition to the power-saving features in the GSS technology, the RBDS-based signaling supports targeted messaging to micro geographies, over-the-air programming and activation, scanning algorithm to allow receivers to roam uninterrupted nationwide and addressable down to the chip level much like an ESN in a cellular devices.
Silicon Labs has introduced a family of FM receiver ICs that support integrated antennas, digital audio out, worldwide FM band support and Radio Data System (RDS) technology, all on a single chip measuring 3mm on a side. Silicon Labs ICs use a patented tuned-resonance technology that allows integrated FM antennas constructed of printed circuit board (PCB) traces, loops, stubs or other devices to perform as well or better than the headset-cord wired antennas they replace.
The partnership integrates message distribution systems, and enables emergency managers to warn the public through mobile and consumer electronics devices. ...
