Important information on WLAN and
Bluetooth
WLAN (Wireless Local Area Network) is the
term used to describe a wireless local net-
work. Bluetooth and WLAN provide a radio
link on the free 2.4 GHz ISM band (ISM:
Industrial, Scientific, Medical). This fre-
quency range is subject to state legislation,
can however be used without a license in
most countries. Consequently a large num-
ber of applications and devices employ this
frequency band for transmission. This can
result in frequency interference and faults.
Depending on ambient conditions, the
radio link may deteriorate, e.g. in the case
of Bluetooth links, cordless telephones,
radio-controlled thermometers, radio-con-
trolled garage door openers, radio-con-
trolled light switches or radio-controlled
alarm systems.
i
Bluetooth can cause bandwidth collapse
in the WLAN network. The antennas of
Bluetooth and WLAN devices should be
at least 30 centimeters apart. Use the
USB extension cable (special accesso-
ry) to maintain a distance between the
Bluetooth USB adapter on the computer
and the WLAN antenna.

Extreme caution is to be taken if wearing
pacemakers or other vital electronic
devices when using wireless systems, as
proper functioning of these items could
be impaired.
Pay attention to the following to ensure the
best possible connection:
¶
The radio signal always tries to find the
most direct path. When setting up the
computer and access point, make sure
there are as few obstacles as possible
(e.g. steel doors and concrete walls)
which could interfere with the signal
from and to the Mastertech II VCI.
¶
Inside buildings, the range of the WLAN
/ Bluetooth is also greatly influenced by
the construction materials used. Con-
ventional masonry, wooden walls and
various types of dry construction wall
scarcely impair the propagation of radio
waves. Thin gypsum walls are however
problematic, as considerable amounts of
moisture may accumulate in the gypsum
and result in the absorption of radio
signals. Metal walls and concrete (in par-
ticular reinforced concrete) largely block
out radio waves. Cellar ceilings are often
impenetrable. Generally speaking, walls
with a lot of installed metal (e.g. pipes,
cables) obstruct radio waves.
¶
Radio reception is also impeded by large
metal objects such as radiators and
window frames as well as active sources
of interference such as radio telephones,
motion detectors and microwave ovens.
¶
Human beings are also an obstacle to
wireless transmission. It must therefore
always be ensured that no-one stands
between the transmitter and receiver.
¶
We advise having the network infra-
structure installed and maintained by a
network specialist.

the SSID and the codes for the wireless
