Communication radio

The FDAP Gen3 has wireless compliant radios that operate in the 2.4 GHz ISM band. It

uses spatial antenna diversity with sophisticated error correction schemes to improve

communication and increase coverage in a typical industrial complex where multi-path

propagation is prevalent.

The FDAP Gen3 Anchor has wireless compliant radios that operate in the 2.4 GHz ISM

band. Communication Radio 1 used for process instrumentation communication with

ISA100.11a and WirelessHart devices. Communication Radio 2 used for RTLS application

to measure or find the distance between FDAP Gen3 Anchor and RTLS tags location.

Antennas

The FDAP Gen3 uses dual antenna diversity to improve communication reliability in severe

multi-path environment. This helps in improving radio coverage and provides robust

communication links thereby reducing infrastructure cost and cost per wireless field

device.

The FDAP Gen3 and FDAP Gen3 Anchor have an integral omni-directional antenna and it

also supports a variety of high- and low-gain omni-directional antennas to provide

flexibility in installation and to maximize performance of the wireless system. See the FDAP

Gen3 Regulatory Compliance Guide for details about certified antennas and the allowable

maximum RF output power.

The FDAP Gen3 and FDAP Gen3 Anchor have an option to integrate lightning Surge

arrestors on the antenna ports. Lighting Surge arrestors are required for all outdoor

installations or indoor installations where FDAP Gen3 may be subjected to lightning surge.

Optional remote mounted lightning Surge arrestors are available for use in application

where the remote antenna cable is exposed to lightning surge.

LED indicators

The FDAP Gen3 and FDAP Gen3 Anchor have six LEDs for indicating the status and health

of the device. For more information about LEDs, see
