Microwave radio signals are electromagnetic waves short wavelengths and high high frequencies between 500 MHz to 300 GHz. About 35 percent of all terrestrial communication is maintained by microwave radio relay systems. There are various types of microwave radio communication systems, operating anywhere between 15 miles to 4,000 miles, including feeder service or intrastate microwave systems and long-haul microwave systems.
Disadvantages of Microwave Communication
As we know microwave is used for microwave communication. Following are the disadvantages of Microwaves:
➨For the frequencies which are below 30MHz standard circuit analysis can be applied. For the frequencies in the microwave range, E-H wave analysis need to be applied.
➨As we know lumped components such as resistors, inductors and capacitors do not have same characteristics at microwave frequencies as they have at lower frequencies. Hence it is difficult to implement these components at microwave frequencies.
➨At microwave frequencies, transit time of current carrier i.e. electron is higher which takes large percentage of actual signal. Due to this fact, conventional transistors do not function properly at microwave frequency compare to lower frequency.
➨As microwave communication is limited to line of sight mode only, Other modes of communication are not possible.
