DirectBand
From Wikipedia, the free encyclopedia.
DirectBand is a new communications technology for continuously delivering time, sports, weather, news and relevant web-based information to your wristwatch.
It uses the deregulated (1983) sidebands (or subcarriers) available to broadcasters operating FM radio stations, that normally are utilised for RDS (Radio Data System).
DirectBand is a two-chip set that consists of a system-on-chip processor which includes an ARM7 CPU along with SRAM and ROM, and a radio chip that contains a tiny, sensitive 100 MHz RF receiver.
