1.1 Scope
This standard 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. This standard also defines
these modes, but does not define the means by which they are accomplished. These are left as
vendor-optional features. These beacons shall transmit at a power level that can facilitate reception at
ranges of at least 300 meters open field separation between the transmitter and receiver. Each receiver
shall be capable of receiving and processing data from a minimum of 120 tag beacons per second. Such
RTLS transmitters shall be fully compliant with US radio frequency regulatory requirements and shall
have the broadest possible international frequency compliance. RTLS enables the user to locate, track
and manage assets within the infrastructure of the system on a real-time basis. The nominal location data
provided by the RTLS shall be within a 3-meter radius of the actual location of the transmitting RTLS
transmitter. The RF transmissions are low power, compatible with, and shall not interfere with existing
standardized IEEE 802.11 wireless communication networks, as per artifact test document, and systems
compliant with ANSI INCITS 256.
