Sierra Radio Systems site controllers are used to monitor and control remote radio and equipment sites. Applications include monitoring repeater systems, broadcast equipment, wireless ISP installations, paging equipment and solar power infrastructure.
These control systems are internet enabled for remote access or connected to Sierra Radio repeater control systems for control through a radio network.
These systems are used to monitor key “vital signs” at remote sites including RF power, temperature, voltage, current and switch closures. Systems can also control RF relays, small signal relays, high power relays and AC circuits.
The Sierra Repeater Controller is the worlds first commercial quality repeater control system featuring a modular and expandable open source linux computing platform.
The CommServer’s built in apps include voice telemetry, remote access and integration with radio site monitoring and control equipment. Built on the Ubuntu linux operating system, the CommServer software is provided as open source allowing users to modify and expand it’s functionality.
