radar communication isfaster and has less attenuation(loss of signals).it is wireless so more preferred over other modes of communication
You don't need to connect wire between the wireless device it is easy to set than cable devices.use anywhere with Wi-fi availabilityuse in any room in your house
No cables to trip over
see www.soe.ucsc.edu/classes/cmpe150/Fall05/lecture6.ppt for the answerAnswerThe biggest is less attenuation (degradation) of signal, so that a message can travel significantly further over an optical fibre than over a copper (twisted pair of coax) cable before it becomes too garbled to understand. In addition, fibre optic cables are generally immune to electromagnetic interference (such as strong electrical or magnetic fields) nearby, while copper cables can have such interference reduce or completely destroy their ability to carry signals. Finally, it is much easier to transmit on multiple channels (frequencies) over fibre than over copper, so a fibre optic cable can handle many more simultaneous message streams than twisted pair or coax. In short: fibre allows hugely greater distances between endpoints, is practically immune to outside interference, and can handle hundreds or thousands of times more signal channels than twisted pair or coaxial cable.

Infrared transmission is advantageous because it is less prone to interference from other wireless signals, has low power consumption, and can be used for communication over short distances securely.
A wireless network is used with out wiers but your internet ill be slower
Optical fiber offers several advantages over traditional copper wiring, including faster data transfer rates, greater bandwidth capacity, increased resistance to electromagnetic interference, enhanced security, and less signal degradation over long distances. Optical fibers have numerous advantages over traditional copper wires. Read on to learn how optical fibers offer faster speeds, better signal quality, higher bandwidth, and greater durability, making them a preferred choice in many industries.

Wireless internet radio has many advantages over regular radio. Wireless internet allows access to a larger number of channels and is generally available in more areas.
# Optical fibres can carry more information as opposed to conventional cables. # Optical fibres are not affected by radio frequency interferrence # Information carried in an optical fibre can only be tapped physically (to steal information, the thief has to work on the optical fibre so that the light will travel to the thief)
