Wireless N Adapter RNX-N250UB User Manual
This is the simplest network configuration with several computers equipped with
the PC Cards that form a wireless network whenever they are within range of one
another. In ad-hoc mode, each client is peer-to-peer, would only have access to
the resources of the other client and does not require an access point. This is the
easiest and least expensive way for the SOHO to set up a wireless network. The
image below depicts a network in ad-hoc mode.
b) Infrastructure Mode
The infrastructure mode requires the use of an Access Point (AP). In this mode, all
wireless communication between two computers has to be via the AP. It doesn’t
matter if the AP is stand-alone or wired to an Ethernet network. If used in
stand-alone, the AP can extend the range of independent wireless LANs by acting
as a repeater, which effectively doubles the distance between wireless stations.
