Connections and structures

Requirements in a mobile network

Types of connections

Point-to-point networks

Communication points need to be in line of sight (LoS) (e.g. sattelite).

Diffusion networks

There is no specific physical relationship between the two communication points (e.g. 802.11).

Semi-diffusion networks

Require some limitations in the relative positioning of the communication points (e.g. Infrared).
