Write An Essay On Wireless Communication Advantages And Disadvantages

1. Introduction
Wireless communication involves the transmission of data over a distance without the need for electrical conductors such as wires or cables. The transmitted distance can be anywhere between a few meters and thousands of kilometres. While radio control is the most common form of wireless communication and most unmanned vehicles use it for operation, other wireless alternatives and alternative radio control methods also exist which possess certain advantages and disadvantages over it. Some of these alternatives are elaborated upon as follows: 2. Alternatives to Radio Communication Systems
2.1. Free-space Optical Communication (FSO):
This method involves propagating light in free space (such as air, vacuum etc.)

iv) Radio telemetry for a UMV is of low cost when deployed on water bodies such as rivers and is easier to deploy.
v) Turbulence detection is also good for such water bodies. vi) Line-of-sight (LOS) based restrictions in transmission do not present themselves.
3.2. Disadvantages
i) One of the biggest disadvantages to radio communication technology is the limited range of a radio signal. Even a powerful radio signal is only capable of reaching receivers within a specific geographic region, requiring that a vast network of radio stations be set up to communicate effectively to a large or spread-out group of receivers (Hartman, n.d). ii) Radio signals are susceptible to interference from atmospheric conditions and other broadcasts. iii) it can be hard to receive a clear signal from certain locations, such as areas shielded by mountains. iv) Many radio waves do not have high frequencies so they cannot transmit a lot of data, in contrast to other means such as microwaves.
v) Radio communication relies on a very limited spectrum of bandwidth frequencies so different radio signals can overlap or
