Wireless LAN – WLAN
Larger Wireless LANs, connection to LANs with one or more base stations
(infrastructure network)
Connecting two LANs via a direct radio link (point-to-point mode)
Connecting of devices with Ethernet interface via base stations (client
mode)
Extending an existing Ethernet network with WLAN (bridge mode)
Multiple radia cells with one access point (Multi-SSID)
Application examples:
Setting-up of an Internet access for WLAN clients
Passing-through of VPN-encrypted connections with VPN pass-through
The ad-hoc mode
When two terminals are equipped with compatible wireless interfaces, they
both can communicate directly via radio. This simplest use is the so-called ad-
hoc mode.
Only in IEEE
802.11b or IEEE
802.11g standard
In ad-hoc networks you connect two or more PCs with own wireless interfaces
directly together for building a Wireless LAN.
This operation mode is generally called peer-to-peer network (spontaneous
network). PCs can immediately get in touch and exchange data.
The infrastructure network
By use of one or more base stations (also called access point), a Wireless LAN
becomes more comfortable and more efficient. A Wireless LAN with one or
more base stati ons is referred t o as an infrastructure network in Wireless LAN
terminology.
Interesting applications arise for the Wireless LAN from the LAN connection
of base stations:
