Microwave Radio Based System
The term Microwave radio Based System refers to the electromagnetic energy having a frequency higher than 1 GHz, corresponding to wavelength shorter than 30cm. Microwave signals propagate in straight lines and are effected very little by the troposphere. they are not the refracted or reflected by ionized regions in the upper atmosphere. Microwave beams not really diffract around the barriers such as hills and large human made structures. some attenuation occurs when microwave energy through trees and frame bases.

Advantages and Disadvantages of Microwave Radio Based System
Advantages:
1. Able to transmit Large Quantities of Data
Microwave radio system have the capacity to broadcast great quantities of information because of their higher frequencies. They use repeaters a device that receives the transmitting signal through one antenna, converts it into an electrical signal and re transmits to large volumes of data over great distance. Microwave radio communication systems propagate signals through the earth's atmosphere. these signals are sent between transmitters and receivers that lie on top of towers. This allows microwave radio systems to transmit thousands of data channels between two points without relying on a physical transmitting medium.
2. Relatively Low Costs
Microwave communication systems have relatively low construction costs compared with other forms of data transmission, such as wire-line technologies. A microwave communication system does not require physical cables or expensive attenuation equipment.
Disadvantages:
1. Line of Sight Technology
Microwave Radio System are line of sight technology, meaning the signals will not pass through objects like mountains, buildings and airplanes. The drawback limits microwave communication system to line of sight operating distances. Signals flow between one fixed point to another, provided no solid obstacles disrupts the flow.
2. Subject to Electromagnetic and Other Interference
Microwave radio system are affected by electromagnetic interference(EMI). EMI is any disturbance that dis grades, obstructs or interrupts the performances of a microwave signals. Microwave signal disruption EMI is caused by electric motors, electric power transmission lines, wind turbines, TV/radio Stations and Cellphone transmission tower. Microwave radio communication is also affected by heavy moisture, snow and others.
Although Microwave Radio Based System can offer a good level of quality, convenience, resilience and security to integrator's and end users. This systems support safe, secure and speedy flow in traffic and people. The nature of the underpinning technologies leads to a different industries.
Microwave Proposed systems e.g. for connecting solar power collecting satellites to terrestrial power grids.
TumugonBurahini see so The term Microwave radio Based System refers to the electromagnetic energy having a frequency higher than 1 GHz, corresponding to wavelength shorter than 30cm. thx for your info
TumugonBurahinMicrowave systems are more reliable than telephone landlines because it cannot be flooded away or no wires can be damage by animals or other means of nature.
TumugonBurahinMicrowave system propagates in a line of sight so it is not good to use microwave system in mountain areas unless you use a repeater.
TumugonBurahinsir, how are microwaves and mobiles linked? it is possible?
TumugonBurahinThank your questioning Jonah..
BurahinAhm. The only similarity between a microwave and mobile is that both uses a electromagnetic radiation but of different frequency for its operation. Microwaves uses micro waves to heat up food molecules where as mobile phone uses radio wave frequency.
I hope that I've answered your question Jonah..
Microwave technology is basically used in cellular systems..It uses line of sight propagation with a range of 1km to 50km or depending on its specification....
TumugonBurahinas for today many users use the Microwave radio system because of features and also some country uses this as their as their emergency services , because of her characteristics Point-to-point digital microwave radio systems are deployed in these networks to inter-connect mobile radio base stations and backhaul the vital communications to the central or regional switches.
