802.11b Access Point (PC Card interface)
If your Versa features 802.11b Wireless LAN
capabilities, you may want to purchase an
access point in order to benefit from the
services provided by your usual wired network,
such as printers, file servers, internet access...
Please note that the 802.11b standard defines
two modes:
In infrastructure mode, the wireless
network consists of at least one access
point connected to the wired network
infrastructure and a set of wireless end
stations. Since most corporate WLANs
require access to the wired LAN for services, they will operate in infrastructure mode.
In Ad hoc mode (also called peer-to-peer mode or an Independent Basic Service Set), a set of
802.11 wireless stations communicate directly with one another without using an access point or any
connection to a wired network. This mode is useful for quickly and easily setting up a wireless
network anywhere that a wireless infrastructure does not exist or is not required for services, such as
a hotel room, convention centre, or airport, or where access to the wired network is barred (such as
for consultants at a client site).
Note: the actual accessories may differ from the pictures shown above.
