Micro Waves

Micro-waves have a wave length between the 30 cm and 1 mm.
This means that micro-waves have a frequency from 1 GHz to 300 GHz.
Micro-waves are similar to light beams concerning reflection and reverberation. They travel at the speed of light.
satellite signals are used by the European satellite operators much used ku-band and are subdivided as follows: 10.7 GHz-11,7 GHz FFS link (Fixed Satellite service): these up links are in use for analogue and digital satellite retransmissions: 11.7 GHz-12,5 GHz BSS link (Broadcast Satellite service): initially intended for direct retransmissions on high capacity, nowadays mainly uses for digital retransmissions. 12.5 GHz-12,75 GHz FSS link (Fixed Satellite service); uses for telecommunication and services specific to the consumer.
Above ku-band frequencies is for reception of satellite signals.
The satellite operator transmits from its ground station to the satellite.
These signals are themselves between 14 and 18 GHz. Micro-waves reproduce themselves in a straight line and experience no change in the troposphere (at an altitude of approximately 10 KM).
In contrast to radio waves they are not reflected in the ionosphere (between 100 and 300 KM) as a result of which ku-band signals the can reach the geo-stationary satellites.
