Landfill operations require monitoring and control for leachate pumping operations and for methane gas collection.

Remote Monitoring and Telemetry for landfill applications can be difficult due to nature of the landfill.  Wireless technologies are typically used, since hardwiring within a landfill is not practical. Wireless technologies like licensed and unlicensed radio can be used but may encounter problems due to obstruction by berms and by the gradual build up of landfill over time. Similarly, cellular technology may encounter similar problems due to these obstructions.  Satellite technology can be an option as the view of the satellite relative to the satellite transceivers can provide clear line of site.

Unlicensed and Licensed Radio Systems Obstructed by Terrain

Radio modem systems can be obstructed by the terrain and may require use of repeater sites, or mesh networks.  Sometimes buildup of landfill can cause RF obstruction issues that are not present when a system is initially deployed.

Cellular Communication Obstructed by Terrain

Sites can be obstructed from reliable cellular communications as shown.

Satellite Communications Have Clear RF Path


SCADALink Satellite based terminals such as the SAT100 and SAT110 utilize geosync satellite communications with a look angle of 25 to 90 degrees above the horizon allow it to clear obstrutions.  SCADALink Dual mode Sat/Cell Modems such as the SAT120 and SAT130 dual mode Sat/Cellular operation allows equipment to rapidly deployed. Dual mode operation can allow the most cost-effective communications method to be deployed, with lowest change of RF path obstructions.
