Write some advantages and disadvantages of micro waves.

Some advantages of micro waves are:

1. It proves cheaper than cables.
2. It offers freedom from land acquisition rights.
3. It offers ease of communication over difficult terrain.
4. Microwaves have the ability to communicate over oceans.

Some disadvantages of micro waves are:

1. It is an insecure communication.
2. Signals from a single antenna may split up and propagate by slightly different paths to the receiving antenna. When these out-of-phase signals recombine, they interfere, reducing the signal strength.
3. Its propagation is susceptable to weather effects like rains, thunder storm, etc.
4. Bandwidth allocation is extremely limited in case of microwaves.
5. The cost of design, implementation, and maintenance of microwave links is high.
