Information technology. Real-time locating systems (RTLS) -- Direct Sequence Spread Spectrum (DSSS) 2,4 GHz air interface protocol: Transmitters operating with multiple spread codes and employing a QPSK data encoding and Walsh offset QPSK (WOQPSK) spreading scheme
ISO/IECÂ 24730-2 is comprised of a main document and two additional parts, ISO/IECÂ 24730-21 and ISO/IECÂ 24730-22, and defines a networked location system that provides X-Y coordinates and data telemetry. The system utilizes real-time locating systems (RTLS) transmitters that autonomously generate a direct sequence spread spectrum radio frequency beacon. These devices can be field programmable and support an optional exciter mode that allows modification of the rate of location update and location of the RTLS device. ISO/IECÂ 24730-2 defines these modes, but does not define the means by which they are accomplished.
This part of ISO/IECÂ 24730 is the mode of ISO/IECÂ 24730-2 transmitters operating with multiple spread codes and employing a quadrature phase shift keying (QPSK) data encoding and Walsh offset QPSK(WQPSK) spreading scheme.
