Figure 3.1. ADHOC Mode
In ADHOC (simple mode), all wireless devices are paired, and can
use wireless communication with the other device in the pair.
Lines can be duplicated using a spanning tree if bridges are
constructed using AP connections.
･ Advantages
(1) Requires virtually no setup work to start.
(2) Can bridge multiple wired LAN's, allows duplication of lines.
･ Disadvantages
(1) When the AP is a relay point the available communication
range is narrower than in infrastructure mode.
(2) Not suited to construction of large wireless LAN environments.
Note!
When configuring a wireless LAN in simple (ADHOC) mode, be
sure to place all wireless terminals within effective communication
range. If units are too far apart, communications can be hindered
by partitions or other obstacles causing some terminals to be
unreachable and reducing system throughput.
