Definition
1. Omni Directional(Omni, Point to Multipoint) The Sgnal is dispersedmin all directions.
2. Directional (Yagi or Point to Point) Yagi have range than Omni because they focus all their power in a single direction. The drwaback is that more care is taken to align the communication points. |
