Sensys FLEX-RP-B-LL-2 Repeater
Sensys Networks repeaters can be used to provide a two-way relay between the out-of-range sensors and the access point.
- To/from wireless sensors
- To/from access point
- To/from another repeater (FLEX or RP240)
- Supports operating in two directions with one repeater; its supported sensors communicate with the access point
- Maximum single-hop range of ~2000 feet (610 meters) from supporting access point or repeater
- Maximum single-hop range of ~300 feet (91 meters) from sensors with Long Range External Antenna
- Receive Signal Strength Indicator (RSSI, in dBm)
- Link Quality Index (LQI, figure of merit 40-99)
Description
The Sensys Networks Repeater. In cases where 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-ofrange sensors and the access point. A repeater is mounted by the roadside on a pole or other structure. The repeater is positioned so that both the sensors and the tandem repeater or access point are within view and within range.
FLEX Repeaters are second generation repeaters from Sensys Networks that provide antenna options that extends the range of the repeaters and eliminates the need for additional repeaters operating in tandem. The FLEX-RP-BLL- 2 Repeater does not have a replaceable battery. The FLEX Repeater utilizes an enhanced RF chipset and circuitry that improves RF robustness and reduces energy consumption. The FLEX Repeater has an internal antenna and connects with the external antenna.
Antenna Options. The external antenna connects to FLEX Repeaters via a coaxial cable. The antenna, which works in conjunction with a repeater, allows the repeater to be aimed in two directions simultaneously utilizing a pole located between the sensor and access point.
Three types of external antennas are supported: (i) the FLEXANT- 1 with the same RF coverage as the internal antenna, (ii) the FLEX-ANT-2 with Long-Range RF coverage and (iii) the FLEX-ANT-OMNI with omni-directional coverage.
