A SHORT RANGE, LOW POWER COMMUNICATIONS SYSTEM AND A METHOD OF OPERATING THE SYSTEM |
摘要 |
A short range, low power communications system comprises a plurality of transceiving stations (RCM 1 TO RCM 4) capable of communicating in the ISM band, wherein a station wishing to transmit a data packet, transmits the data packet as a low bit rate, direct sequence spread spectrum (DSSS) signal in a spectrum allocation which is common to at least one geographical region and/or a plurality of countries. A carrier sense multiple access (CSMA) protocol may be used to enable the stations to access said spectrum allocation. |
