TEE practice mock · Q6A. List different types of unguided transmission media and write any two characteristics of each. [5 mock marks]
Answer
| Type | Characteristic 1 | Characteristic 2 |
|---|---|---|
| Radio | Can provide broad-area/mobility support depending on band | Shared spectrum/interference and obstacles affect reception |
| Terrestrial microwave | Directional, usually line of sight | Needs antenna alignment; obstructions/weather can matter |
| Satellite microwave | Relay covers large or remote areas | Delay/capacity depend strongly on orbit/system |
| Infrared | Short range and generally blocked by opaque walls | Limited room-scale coverage reduces inter-room interference |
Many classifications group satellite links under microwave rather than making a separate spectral category. State that grouping consistently.
