IRELESS NETWORK BOARD
(
WITHOUT CABLES
)
This is a board connected directly to the
CPU Board
, which enables the VISIO device to connect to
a
WLAN
(wireless local area network) as an alternative to a wired network.
The VISIO device has been constructed to be compatible with
technology (and in particular
with the IEEE 802.11b/g standard), which offers a theoretical bandwidth capacity of up to 54Mbps
over distances dependent on the characteristics of the setting where it is installed.
The typical indoor range is 30 m (open space):
Standard: IEEE 802. 11b/g
Frequency band: 2.4GHz
Security protocol: WPA/WPA2 or also less recent ones (e.g. WEP).
The WLAN connection may not guarantee the same performance as a wired network.
The advantage of Wi-Fi is the absence of cables, but this is also a limitation in terms of
protection against interference/disturbance, performance (the stability of service and
bandwidth may be intermittent) and security (vulnerability to attacks by hackers). Where
possible, it is in any case preferable to use the wired network. The possibility of using
Wi-Fi also depends greatly on the type of service/application that is to be used in
VISIO.
In particular:
•
Technogym Communicator: usable with suitable Wi-Fi network
•
IPTV: NOT usable with Wi-Fi network; for this application, use of a wired network is
essential.
There are 2 different models of Wi-Fi network board used by Technogym, one produced by
VIA
and
the other by
Billionton
. The 2 boards, as you can see in the picture below, are physically different
and can be identified one from the other.

Billionton model
Whenever you replace the board with another that is not the same model, you always
have to carry out the “System recovery” procedure using the Recovery USB sticks.
