Description
Defines the communication mode. The communication
mode defines the network structure in which the UTN
server will be installed. Two modes are available:
- In the 'Ad-Hoc' mode, the UTN server communicates
directly with another WLAN client (peer-to-peer).
- The 'infrastructure' mode is suitable for setting up large
wireless networks with several devices in different
rooms. Communication between the devices is done via
an access point which is connected to the network. The
access point can be protected by encryption or authenti-
cation.
Defines the SSID. The ID of a wireless network is
referred to as SSID (Service Set Identifier) or network
name. Each wireless LAN has a configurable SSID in
order to clearly identify the wireless network. The SSID is
configured in the access point of a Wireless LAN. Each
device (PC, UTN server, etc.) that is intended to have
access to the wireless network must be configured using
the same SSID.
Enables/disables the use of roaming. Roaming refers to
the 'moving' of one radio cell to the next. The UTN server
will use the access point that has the strongest signal. If
the UTN server moves towards the sphere of another
access point, the UTN server switches automatically and
without loss of connection to the next radio cell. The
parameter 'Roaming' can only be configured in the 'Infra-
structure' mode.
Defines the transmission power (in -dBm) of the UTN
server. The value 65 -dbm is preset. The parameter
'Roaming Level' can only be configured in the 'Infrastruc-
ture' mode.
Defines the channel (frequency range) on which the
entire data communication will be transmitted. The prod-
uct uses the 2.4 GHz ISM band. A channel has a band-
width of 22 MHz. The distance between two neighboring
channels is 5 MHz. Channel 3 is preset. The parameter
'Channel' can only be configured in the 'Ad-Hoc' mode.
Neighboring channels overlap, which can lead to interfer-
ences. If several WLANs are operated in a small radius,
a distance of at least five channels should exist between
two channels.
Keep yourself informed about national provisions
regarding the use of WLAN products and only use
authorized channels.
