Bed.

1.1.1 Communications Test Bench

The communications test bench (CTB) is a collection of equipment and accessories used to stage tests of various radio and PLC types. The purpose of the CTB is to measure physical aspects of communication systems as well as to observe how higher protocol layers operate under changing physical conditions. (e.g., how does a mesh radio network reconfigure when communications to one of the member nodes fades.)

This setup can be used to compare performance of radios operating in VHF, UHF, 856-868 MHz, 915 -935 MHz, WiFi bands, in mesh or point-to-multipoint configurations. A spectrum analyzer is used to monitor radio performance and verify RF operating parameters. Bench-type adjustable power supplies should be available to power radio equipment that normally utilizes low-voltage DC power inputs.

PLC systems are similar to wireless systems in terms of testing since they are essentially the same

type of technology except they utilize couplers to transmit their signals on power cables instead of

using antennas to send RF energy through free space. For this reason, much of the equipment

specified for wireless testing will find use on PLC testing. The main addition to the CTB for PLC will

be a set of couplers used for safely measuring the signals coupled to an active power line.

of testing is centered around lab testing using test and development type modules to allow a wide

access to configuration and performance tools.
