2. Microwave Communication is the
method of wirelessly sending data. It is
very similar to radio technology

3.  Modern microwave systems are used in
Telephone networks and ISPS(International
Ship and Port Facility Security)
 It is used by power utilities to remotely
manage the power-grid.
 These are used by public safety agencies
{Police,Fire} for remote monitoring and
management.
 Many industries are used microwave and they
do it for one important reason.
