WDS é complicado acho que seja furada
WDS can be used to provide two modes of wireless AP-to-AP connectivity:
* Wireless Bridging in which WDS APs communicate only with each
other and don't allow wireless clients or Stations (STA) to access
them
* Wireless Repeating in which APs communicate with each other and
with wireless STAs
Two disadvantages to using WDS are:
* The maximum wireless effective throughput is halved after the
first retransmission (hop) that is made. For example, in the case of
two routers connected via WDS, and communication is made between a
computer that is plugged into router A and a laptop that is connected
wirelessly using router B's access point, the throughput is halved,
because router B has to retransmit the information during the
communication of the two sides. However, in the case of communications
between a computer that is plugged into router A and a computer that
is plugged into router B, the throughput is not halved since there is
no need to retransmit the information.
* Dynamically assigned and rotated encryption keys are usually not
supported in a WDS connection. This means that dynamic Wi-Fi Protected
Access (WPA) and other dynamic key assignment technology in most cases
can not be used, though WPA using pre-shared keys is possible. This is
due to the lack of standardization in this field, which may be
resolved with the upcoming 802.11s standard. As a result only static
WEP or WPA keys may be used in a WDS connection, including any STAs
that associate to a WDS repeating AP.
Recent Apple base stations allow WDS with WPA, though in some cases
firmware updates are required. Firmware for the Renasis SAP36g Super
Access Point and most third party firmwares for the Linksys
WRT54G(S)/GL support AES encryption using WPA2-PSK Mixed Mode
security, and TKIP encryption using WPA-PSK, while operating in WDS
mode. However, this mode may not be compatible with other units
running stock or alternate firmwares.
Melhor você pensar em arquitetura MESH. se este conceito de rede wifi
ja esteja em desuso.
