Sensys: RP240-BH-LL “Long Life” Repeater
Sensys Networks repeaters can be used to provide a two-way relay between the out-of-range sensors and the access point.
- Radio Communications Relay
- Extended Range and Coverage of AP
- Fully wireless – no cabling or wiring
- Radio signal quality measurements
- Over-the-air firmware upgrades from AP
- Simple installation
- Virtually maintenance free, no calibration or adjustments needed
In cases where one or more installed Sensys Networks wireless sensors are out of range of the nearest access point, one or more Sensys Networks repeaters can be used to provide a two-way relay between the out-of-range sensors and the access point. As many as two repeaters operating in tandem can be installed between a sensor and the access point. To simplify its deployment, a repeater is battery powered and thus requires no wires or cabling.
Mounted by the roadside on a pole or other structure, the repeater must be positioned so that both the sensors to be supported by the repeater and the communicating repeater or access point are within view and within range.
The access point and repeater antennas each provide a 120° field of view, allowing considerable flexibility. For example, a repeater can be installed approximately 1000 feet (305 meters) meters from the access point, where each device can then support wireless sensors within 75 – 150 feet (23 – 46) meters. Alternatively, a repeater can be mounted on the same pole or mast as the access point, separated by 2 to 4 feet (0.6 to 1.2 meters) to ensure that they can communicate, but pointed in the opposite direction. The access point would then support the sensors and repeaters directly in front of it, while the repeater pointing in the opposite direction would support its own sensors as well as another repeater and its sensors.
