I would appreciate some help understanding what I have done wrong here. I am
attempting to extend access out to a gazebo about 500-600 feet from my main
location.
My set-up consists of
DLink MI-514 Wireless Router
about 20' of LMR 400 antenna cable
A 8.5 dB Omnidirectional Antenna (no downtilt to the radiation pattern)
A Dell Laptop with a built-in True Mobile card.
Assorted pigtails, adapters, and lighting arrestor.
I mounted the antenna outside the main location about 3' from the ground,
and I have unobstructed LOS to the gazebo.
I thought that this would be a slam-dunk, as the advertised range of the
DI-514 is 300 feet indoors and 1300 feet outdoors (yes, I realize under
"ideal" conditions). I thought putting the antenna outside in direct LOS of
the gazebo would pretty much make the conditions as ideal as possible, as
well as increase the gain in the system.
I estimated the signal strength close to the antenna (accounting for cable
loss, antenna gain, and free space loss) at about
-13dBm.
OK, I ignored any losses in the assorted pigtails, etc..
Using the utilities shipped with my laptop, the received signal levels I
experience are as follows:
at 5 to 10 feet -27 dBm
at 50 feet -50 dBm
at 100 feet -61 dBm
at 150 feet -73 dBm
At each location, I am in full view of the antenna. Beyond 150 feet I can't
hold the signal long enough to get a good reading.
The annoying aspect is that for some reason I can also pick up another
wireless network at all locations, although not reliably. When I can get a
signal from the other network, it appears to be in the -60 dBm to -70 dBm
range. The signal strength is pretty independent of where I am along the
path to the gazebo. In other words, the signal strength from the other
network is stronger in some locations in others, but not clearly stronger at
one end or the other of the path to the gazebo. (I haven't determined which
neighbors signal I have yet, but suspect that a line to their location is
perpendicular to the path to the gazebo.)
Any thoughts??
