2. What are the signal propagation characteristics??
ANSWER
There are three signal propagation characteristics
- Path loss: power falloff relative to distance
- Shadowing: random fluctuation due to obstruction
- Flat and frequency selective fading: caused by multipath
3. What are the different mode of radio wave propagation??
ANSWER
Ground Wave, Sky Wave, Space Wave
