Radio Wave Transmission

We are quite familiar with Radios and their working. Each radio signal uses a different frequency and this differentiates it from others. The transmitter takes some message, encodes it, and then transmit it with the radio wave. The receiver on the other end receives the radio waves and decodes it. Both the transmitter and receiver use antennas to radiate and capture the radio signal. Radio transmission is widely used by delivery services, policemen, security personals, etc.

Advantages of Radio Wave

1. It is easy to communicate through radio waves in difficult terrains since there is no need for any type of cable.
2. It can travel long distances in all directions. Also they can easily pass through obstacles like buildings so it can be used anywhere.

 Disadvantages of Radio Wave

1. Data Transmission is not secure.
2. The radio wave is susceptible to weather effects like rains, thunderstorms, etc.
