Atmospheric attenuation of microwaves in dry air with a precipitable water vapor level of 0.001 mm. The downward spikes in the graph correspond to frequencies at which microwaves are absorbed more

Microwave transmission refers to the technique of transmitting information over a microwave link. Since microwaves are highly susceptible to attenuation by the atmosphere (especially during wet weather), the use of microwave transmission is limited to a few contexts.

[edit] Properties

• It is only suitable over Line of Sight transmission links
• Provides good bandwidth
• Affected by rain, vapor, dust, snow, cloud, mist and fog, heavy moisture
• Not suitable for links where an obstacle is in between the transmitter and receiver

[edit] Uses

• Backbone carriers in cellular networks. Used to link BTS-BSC and BSC-MSC.
• Communication with satellites
• Microwave relay links for television and telephone service providers
