Ad-hoc network
In an ad-hoc network, PCs communicate with each other via wireless peer-to-peer con-
nections. An ad-hoc network is set up by participants as and when required. All the PCs
must have a wireless network adapter installed, e. g. a Gigaset PC Card 54, a
Gigaset USB Adapter or USB Stick 54 or a Gigaset PCI Card 54. Ad-hoc networks are used
wherever communication networks have to be set up quickly without any existing net-
work infrastructure and the participants are mobile.
Infrastructure network
In an infrastructure network, connections between network participants are set up via
an Access Point (or several Access Points). The Access Point provides the basis for the
wireless network. It controls the connections between the participants and can also
establish the connection from the mobile stations of a wireless network to a wired LAN
(Ethernet) or the Internet.
Roaming
Several Access Points can be installed to extend the range of a wireless network. Partic-
ipants in the wireless network can move freely between the various Access Points with-
out losing contact to the network. As soon as there is a risk of losing contact, the PC
automatically looks for another Access Point with a stronger signal. All Access Points and
wireless network adapters must have the same SSID. All Access Points must be con-
nected to the same Ethernet network.
