Country-specific roaming
This device has the International Roaming function (IEEE802.11d) which ensures that the
device is used on the channels prescribed for the respective country.
Ad-hoc operation
The ad-hoc operation is restricted to the channels 36–48 (5150–5250 MHz). The use of
this bandwidth is restricted to indoor areas; use outdoors is not permitted.
6.4
Operating frequency - FCC and IC
5 GHz only
Use in the UNII-Band 1 (Unlicensed National Information Infrastructure) in the range of
5150-5250 MHz is restricted to indoor rooms. The failure to heed this rule leads to the
illegal operation of the device.
Industrial standard declaration for Canada
ATTENTION
Devices can be damaged by inappropriate handling!
The device for the frequency range 5150-5250 MHz is exclusively intended for
operation in indoor rooms in order to restrict possible co-channel interference for
satellite mobile radio systems to a minimum. The frequency ranges 5250-5350
MHz and 5650-5850 MHz are primarily intended for the high power radar devices
(i.e. these radar devices take priority). These radar devices may cause
interference and/or damage WLAN devices.
2.4 GHz only
In the USA the channels 1 to 11 are available for the 802.11 b/g operation. The range of
channels is restricted by the firmware.
FCC requirements to protect against high-frequency interference
This device has been tested and satisfies the limit
values for a digital device of Class B according to Part
15 of the FCC Guideline. These limit values were
stipulated to guarantee appropriate protection against
disturbances if the device is used in residential areas.
The device generates and uses radio frequency energy and may emit this energy. This
can have a disturbing effect on other radio frequencies if the device is not connected and
used in accordance with the operating instructions. A guarantee that no interference will
arise for a certain installation cannot be given.
If the device causes interference to the radio or TV reception which can be recognised by
switching the device on and off, the interference should be eliminated by one or several of
the following measures:
-
Re-alignment or moving of the receiving aerial.
-
Enlarging the distance between device and receiver.
