Microwave Radio Parameters

Loss , Reflection , Refraction , Diffraction , Polaraziation , Scattering , Absorption , Fading , Intereference , Attenuation are the parameters of microwave radio communication system which will be discussed here by.

Loss : loss means decrease in siganl amplitude , which can caused because of many reasons like : resistance of cable , connectors , loss because of heat impedance mismatch.

Microwave Frequency Allocation range.

WPC and SACFA has declared the microwave frequency range as.

6 and 7 GHz frequency range for Distance 5-50 Kms also called as Long Haul.

15,18 and 23 GHz Frequency Band are used for Access Networks distance 1-15 Km also called as Short Haul.

Who does the Microwave Frequency Allocation.?

WPC : Wireless Planning committee , it is a government wing which take charges from operator for use of microwave frequency pair.charges they take are based on bandwidth used and annual gross revenue of the company.

SACFA : Standard Advisory Committee for frequency Allocation , it is government wing which allocates frequency and also gives tower height clearance to the telecom operators.

SACFA,ensures this thing that their is no inter fence between existing users before allocations of frequency.

SACFA, Checks before giving tower height clearance that , it should not cause obstruction to existing microwave links of other operators and should not be in a funnel zone of aircraft.

Appliction of Microwave Radio.

As a back haul radio For Mobile Coverage.
Long Haul for STM1 connectivity.
Point of interconnect Connectivity.
Microwave Equipment for Customer Connectivity.

What is Microwave Radio.?

Basically microwaves are electromagnetic waves with wavelength shorter then one meter and longer then one millimeter or can say frequency ranging betweeen 300mhz to 300ghz combining UHF,SHF,EHF.
