4.5 WLAN and Bluetooth
4.5.1 General information about WLAN and Bluetooth
The device supports Bluetooth to standard 4.0.
The device is equipped with a network card for Wireless LAN (WLAN), i.e. you are not
assigned to a cable network.
Depending on the infrastructure and the access rights set by the network administrator, you
have exactly the same access to files, the printer and to the Internet with WLAN as with
cable network.
Support is provided for the WLAN frequency ranges 2.4 GHz and 5 GHz.
Depending on the surrounding conditions, you can create connections through walls or at
distances in the open air of up to 100 m.
The on-board network adapter operates based on the following standards:
● IEEE 802.11 a
● IEEE 802.11 b
● IEEE 802.11 g
● IEEE 802.11 n
● IEEE 802.11 ac
The IEEE standard offers two modes of operation, the ad hoc mode (Peer to Peer) and the
infrastructure mode.
Ad hoc mode
The ad hoc network refers to a wireless network that is established directly between several
computers, whereby all computers must have a WLAN facility. No additional devices are
necessary.
Infrastructure mode
The infrastructure network uses access points to connect computers to wired networks with
the aid of WLAN. These can be a local network (e.g. company networks) or a global network
(e.g. Internet).
More detailed information on configuring and operating the WLAN can be found in the online
help of the WLAN network adapter.
