What is Microwave Communication A communication system that utilizes the radio frequency band spanning 2 to 60 GHz. As per IEEE, electromagnetic waves between 30 and 300 GHz are called millimeter waves (MMW) instead of microwaves as their wavelengths are about 1 to 10mm
Microwaves are very short waves in the upper range of the radio spectrum used mostly for point-to-point communications systems. Much of the technology was derived from radar developed during World War II. Initially, these systems carried multiplexed speech signals over common carrier and military communications networks; but today they can. Systems which use microwave frequencies are radar, mobile radio, satellite communications, terrestrial line of sight and troposphere links. An essential property of microwaves is that they travel in straight lines through the atmosphere, are not affected by the ionized layers Microwave communications are ideal for television and radio broadcasts, while satellite communications are used for communicating to ships and aircrafts, relaying telephone calls and providing communications to remote areas. Microwaves can be focused and received via aerial antennas
Microwave signals are electromagnetic (EM) waves that propagate at a velocity of 3 x 10 8 m/s in free space. Polarization of an EM wave is the direction of the electric field vector. The magnetic field vector is always orthogonal to (90° from) the electric field vector As you know that the radio wave can be classified by frequency and wavelength. When frequency is higher than 3 GHz, then it is named microwave. Satellite communication is a special case of microwave relay system. Satellite communication use the synchronous satellite to relay the radio signal transmitted from the ground station

As per IEEE, electromagnetic waves between 30 and 300 GHz are called millimeter waves (MMW) instead of microwaves as their wavelengths are about 1 to 10mm
Terrestrial microwave transmission is when microwaves are used to transmit data. Because of the curve of the Earth's surface, the repeaters must be constructed every 30 miles. This type of transmission is used for both television and radio. In both cases the signal will originate from a large parabolic dish set as high up as possible Radar system, aircraft navigation and microwave oven.

The SICN takes advantage of FDOT Districts' installed fiber optic facilities, where available, along with the SMS in other areas, to effectively complete interconnections
Polarization in communication systems. Polarization requirements depend on how the system is used. For example, if you wanted to create a comm-on-the-move system that points to a satellite, the system would likely have to use circular polarization so that the antenna (and the vehicle it is mounted on) could rotate with respect to the transmitter Wireless and microwave point to point links are widely used as a quick-to-deploy and cost effective alternative to fiber optic cabling for interconnecting the network of two sites with distances of few hundred meters and up to 50 km or more

Microwave frequencies are widely used for communication and interaction between objects (Body area network, Internet of things), leading to the development of various embedded sensors for the monitoring of vital signs (temperature, heartbeat, respiration, arterial pressure) or the follow-up of some kinds of pathologies (glucose level, water in the lungs, cancer tissues, ) [2-5] The cause of their shared plight was a total mystery to Beck until 2012 when he saw US intelligence communications about a microwave weapon with potentially debilitating neurological effects. These were called flyswatter antenna systems, and they were phased out when satellite communications became widely used. SCE still has microwave links in some parts of the system, but the MW network is a shadow of its former self; fiber optic systems can carry a lot more data and don't require trips to mountaintop repeaters Microwave dishes come in many sizes and several frequencies, but they all have similarities. They are a point-to-point communication system. Whereas an average macro-cell tower has sectors of antennas that area aimed towards the ground to cover any wireless customer who is in that blanket of coverage, microwave dish links can span a very great distance by sending data from dish to dish to dish.

Definition: Noise in a communication system is basically undesirable or unwanted signals that get randomly added to the actual information carrying signal.Resultantly, causes disturbances in the original signal being transmitted from an end to another. The presence of noise in the system causes interference in the signal being transmitted and this ultimately causes errors in the communication. antenna system for wireless communications IEEE MTT-S Int.
