Jack,
It appears that I am a lousy estimator of distance. I paced it off the other
day and the gap is roughly 90 feet between buildings. I also took a close
look at their antennas from across the street, and the main building's Yagi
appears to be pointing about six feet over the top of the receiving Yagi. I
think the person who initially installed it used the wrong antennas for this
distance. Since a Yagi has a very narrow beam, I would expect them to have
to be pointing down each other's throats to work well.
This theory also fits what is seen at the site. The remote antenna points
directly at the main one, while the main one shoots over the remote's head.
The data transfer from remote to main is 20Mbps and the transfer from main
to remote is 3Mbps. The current bridge is done using two year old Netgear
WG102 units with PoE. The client does not have the password to get into them
to see the settings, and I cannot down the link to reset the units to
default for access unless I go there on a Sunday.
Out of curiosity, I asked Netgear which unit would be best and they
recommended the WAG302, partly because you can use 802.11a to eliminate a
lot of interference. Since they tout this unit as 108Mbps-capable, I asked
about the maximum theoretical bridge speed, which they said would be 54Mbps.
I wonder if that is correct. I tried D-Link's DWL-2100AP set to use 108 and
it only bridged at 23Mbps, according to QCheck.
Do you know what the theoretical maximum would be for 54G and 108G
equipment?
