Infrastructural Requirements of a Wireless Network

As mobile networks transitioned from 2G to 3G and now 4G technologies, the infrastructural requirements for connectivity have dramatically increased. Where 2G networks could provide coverage with towers spaced several miles apart, modern networks need cell sites located much closer together- in some cases only a mile or less apart- to deliver the bandwidth and speeds today's smartphones and applications demand. Meeting the infrastructural needs of a high-speed wireless network requires telecom operators to build or lease an extensive array of telecom towers.

According to industry estimates, over 500,000 towers have been installed across India to support growth in 4G use and the proliferation of smartphones. With fiber backhaul, advanced antennas and equipment supporting technologies like LTE, these towers have become the vital backbone connecting people in urban as well as far flung rural regions. However, constructing this tower infrastructure came with massive investments and overcoming hurdles related to siting approvals and power requirements in remote areas.

Addressing Challenges in Tower Installation and Maintenance

Erecting Telecom Towers required site surveys, structural analyses and foundation design suitable for each location considering variables like soil conditions and wind loads. Environmental clearances also had to be obtained as towers could impact avian life. Further, towers needed reliable power which was an issue in off-grid regions not connected to the electricity network. Initially, diesel generators were used but were costly to operate and maintain. Now green technologies like solar hybrid systems help reduce dependence on diesel.

Operational challenges remain in tower upkeep and maintenance. Remote sites are difficult to access, and harsh climate and terrain accelerate equipment wear and tear. Around-the-clock monitoring and quick response teams are crucial to minimise downtime from issues like tower tilts or power outages. Tower companies invest heavily in IT systems and advanced testing devices to remotely troubleshoot problems and schedule predictive maintenance as mandated by regulators.
