Frequently Asked Questions

There are interferences between other devices in the 2.4 GHz 
band and my wireless LAN. What can I do?

Change the channels used by your other devices or your BAT 
11b so that you are using different channels.

Change the location where the BAT 11b or the other devices 
are mounted.

Change the position of your antenna from vertical to horizon-
tal.

How can I increase the range of my wireless network?

You can increase the range by cascading several BAT 11bs in 
the AP and AC mode as described in Section 

Extension of the 

Range

 on 

Page 1–36

.

You can use optical antennas, which you will find in the 
Hirschmann product portfolio, to optimize the transmission 
capacity and the radiation characteristics.

Can the BAT 11b Wireless Ethernet work as DHCP server?

No. In principle, the BAT 11b Wireless Ethernet is a wireless 
hub. It cannot take over DHCP server functions.

Can I execute programs on other computers via a wireless 
network?

This depends on the fact whether your application is designed 
to work over a network. In principle, a wireless network does 
not differ from a wired network. Consult the software manu-
facturer of your application.
