scope:

ISO/IEC 24730-2 is comprised of this main document and two additional parts and defines a networked location system that provides X-Y coordinates and data telemetry. The system utilizes RTLS transmitters that autonomously generate a direct sequence spread spectrum radio frequency beacon. These devices may 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/IEC 24730-2 defines these modes, but does not define the means by which they are accomplished. The two additional parts of ISO/IEC 24730-2 are as follows: ? Information technology - Real Time Locating Systems (RTLS) - Part 21: ISO/IEC 24730-2 transmitters operating with a single spread code and employing a DBPSK data encoding and BPSK spreading scheme ? Information technology - Real Time Locating Systems (RTLS) - Part 22: ISO/IEC 24730-2 transmitters operating with multiple spread codes and employing a QPSK data encoding and Walsh offset QPSK (WOQPSK) spreading scheme
