Computer Room and cell site monitoring
Cellular networks use distributed base stations, also called cell sites for providing radio coverage over a wide geographic area. A standard cell site has several active and passive components, requiring routine maintenance and adjustments. Today, operators are increasingly relying on remote monitoring to perform repairs and maintenance from a central office.
Off-grid cell sites are not connected to the public electrical grid. Usually the system is off-the-grid because of difficult access or lack of infrastructure. Fuel cell or other backup power systems are added to critical cell sites to provide emergency power. More sites use internal-combustion-engine-driven generator sets. In a remote cell site, power issues are one of the most fundamental items that operators will wish to monitor. Other monitoring issues include diesel fuel level, backup battery readiness, temperature and humidity, smoke and water, tower lighting, door open and motion detection, etc.
