Description / Abstract:
ISO/IEC 24730-2 is comprised of a 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 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/IEC 24730-2 defines these modes, but does not
define the means by which they are accomplished.
This part of ISO/IEC 24730 specifies transmitters operating with
a single spread code and employing a differential binary phase
shift keying (DBPSK) data encoding and binary phase shift keying
(BPSK) spreading scheme.
