Question

state unguided media efficiency and reliability

Answer 1

It consists of transmission tower responsible for transmitting or repeating the signal for each hop (the distance is around 30 Kilometers to 50 Kilometers). The microwave in Figure uses the line of sight (the received tower can be visual by the transmitted tower) transmission. The transmission rate can be up to 250M bps. The transmission quality however is subject to weather changes. The use of microwave is ideal for short-haul and high bandwidth applications due to no cabling cost once the transmission tower is built. In Hong Kong, a lot of large public utilities such as China Light and Power and Hong Kong Electric use microwave in transmitting signal for power protection.

Answer 2

the transmission quality of weather changes
