local area networks (

WLAN

s), 802.11g offers wireless

transmission over relatively short distances at up to 54

megabit

s per second (Mbps) compared with the 11 megabits

per second of the

802.11b

(

Wi-Fi

) standard. Like 802.11b,

802.11g operates in the 2.4

GHz

range and is thus compatible

with it.

Question

What is WDS?

Answer

WDS (Wireless Distribution System) is a technology that allow
at a pair of Wireless Multi-Function APs operating under
Bridge mode to act as the bridge that connect two Ethernet
networks or Ethernet enabled clients together. Repeat Mode
is able to extend the effective range and coverage of the
wireless network.

Question

Why 2 AP trasmitting on different channel making
interferences?

Answer

Every channel occupies about 22Mhz; being ISM band made
of 80 Mhz, you can utilize only 3 channel without overlap.
We suggest to set AP with 5 channel interval between 2 AP
utilized. (ex. AP1-channel 1, AP2-channel6).
Interferences are making when 2 or more channels overlap
themselves.
Follow pictures explain this:

Question

Does IEEE802.11b clients works properly with AP
IEEE802.11g?

Answer

It is possible to use IEEE802.11b clients with IEEE802.11g
Access Point.
Performance will be reducing to 11Mbps to guarantee full
compatibility with IEEE802.11b.
