The Booster / Repeater is also available in a number of different housing styles to suite locations devoid of street furniture. This include bollard housings, a covert faux bird houses and the recently introduced solar assisted roadside unit.
All units are battery powered and uniquely feature spatial diversity (dual antenna) for enhance reception of the signals from buried assets under for example manhole covers. Booster / Repeaters are normally supplied to repeat the messages typically every 5-minutes (2-minute for EDM) which is more than adequate for most applications such as meter reading, blocked sewer or CSO overflow monitoring / alarms.
Booster Repeaters are normally supplied 100% pre-configured and pre-tested read to go! Factory configurations include up-link frequency “that is the frequency out of the hole emitted by the sensor such as a BDT Level Transducer” and back link frequency “frequency back to the base station”. Further the electronic serial number (ESN) of the sensors are also pre-configured.
The booster repeaters can be supplied to operate on either licenced or licence free radio spectrum. Typically in a urban or industrial environment the communication radius can be anything from 500m to 5km depending upon the topology. The pickup radius from assets mounted below the manholes is typically 40m to 100m depending upon the mounting position and the type of cover.
Simple to install, simply mount the booster using stainless steel banding strapping, available from our store, at a typical height of 4m above ground level and within typically 30-100m radius of the sensor. Note if mounting on highways lamp columns it is important to affix a property label and to send notice to the owner of the column. For multiple installations this can be done on bulk by just stating the post code and lamp column number.
Compared to replacing batteries of instruments located below streets that can involve costly traffic management, Booster Batteries are simple to replace in a matter of minutes and often require nothing more than a “cherry picker” or short ladder.
