hi all
dear peter, thanks alot for your answer,
I configure my bridges as turbocell base station and another turbocell
satellite station, can I ask,
1- in turbocell mode, that bridges send super frames, what is timing for ack
packets ?
2- my bridge has 2 slots, and in "wireless lans" by walterR. bruce. in page 256
said that in AP's that have 2 card bus, we can insert 802.11a and 802.11b cards
! .... our bridges has 2 card bus, do you think my bridges support 802.11a
cards ?
yours

I do not know, if You have Turbocell loaded in 2 AP1000 devices, or You
are using only one device in AP mode and second point of link is Linux
client in managed mode.
ACK packets are not used for retransmissions in Turbocell. I know
nothing about distance limits in Turbocell.

802.11g cards are 32bit only (cardbus), while AP1000 has only 1 16bit
slots. So it is not possible.

No firmware update will help

Cisco bridges BR350-AK9 has configurable ACK timing via distance
setting. I think, that maximum distance is 40km or 40 miles. You need 2
bridges for point to point link.
May be in Your case, interference will not be big problem. But I think, that
802.11g will not be usable.
I heard something about point to point link in adhoc mode with disabled
ACK. May be it is solution for You, if You need very cheap and relative fast
solution.
