IRELESS NETWORK BOARD
(
WITHOUT CABLES
)
This is a board connected directly to the CPU, 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 Wi-Fi 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, are physically different as shown below:
VIA model 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.
