The macro station is a cellular base station, covering a large area, generally above 1 km, up to 30 km, so the distance between base stations is large, which is suitable for rural areas. Microwave stations are divided into digital microwave terminal stations, relay stations and branch stations. The terminal station is mainly responsible for receiving and sending signals, using relay stations to strengthen amplification and monitoring, and transmitting microwaves wirelessly, which is very suitable for poor road conditions and remote places.
