Each cellular base station is allocated a group of radio channels to be used within a small geographic area called a cell. Neighboring base. . In the world of wireless communication, the choice of channels for base stations plays a critical role in ensuring reliable service, minimizing interference, and optimizing performance. Whether you're setting up a mobile network, Wi-Fi infrastructure, or IoT devices, understanding the channel. . In 1970 Bell had a mobile system in NYC with a single high power transmitter; it could only support 12 simultaneous calls! => Cellular concept was major breakthrough in solving spectral congestion and user capacity constraints. Cell Splitting is based on the cell radius reduction and minimizes the need to modify the existing cell parameters. In mobile-telephone nets these cells are usually hexagonal.
