2.5 General information on the 5GHz version (802.11 A /
802.11 H) ETSI
The device is certified for the use of channels of the 5 GHz band according to ETSI EN 301 893 V1.3.1.
In this case, the user is to observe the following:
Access Point as well as Access Client devices use DFS and TPC by default on all 5 GHz channels, both
for indoor as well as outdoor configurations. The devices can therefore always be operated with 23 dBm
or 30 dBm maximum transmission power.
Information:
Access Points must not shut down the DFS outdoors. An Access Client may
shut down the DFS. This setting is switched off by default.
802.11a channels cannot be set permanently.
Information:
The lower four channels (non-DFS) can be set permanently if the DFS is
switched off. Switching off the DFS also results in the 60s Scan and Radar
Detection functions being switched off, however.
Upon activation of the Access Point, the Access Point performs a one-time radar detection scan and
then waits for a period of time on an arbitrarily selected channel for a radar pulse before operation on
this channel is started. The waiting time depends on the channel and the regulatory domain.
If a radar pulse is detected by an Access Client during operation, this is reported to the Access Point
according to 8011.h. As a result of this or on account of a detection made on its own, the Access Point
changes the channel with a channel switch according to 802.11h.
The maximum permissible transmission power varies by channel. It is therefore necessary that the user
correctly set the antenna gain if the standard antenna is replaced!
2.6 WLAN information
Caution:
This information must be observed when operating the devices:
•The device does not offer a "secure" transmission medium
•The devices do not have a deterministic system behaviour
•No MIN/MAX roaming time can be guaranteed
The setting of the applicable regulatory authority and the antenna gain is the
responsibility of the operating company.
