I want to link two wired networks. The principal uses for the link
will be remotely monitoring security cameras at one location and
sharing a high-speed internet link that is only available at one site.
I need to have fairly decent security, but it doesn't have to pass DOD
standards.
I'm looking at the D-Link DWL-2100AP for use at both sites, mainly
because of the features it claims to offer.
The distance will be around 2 miles, and I will need about 40 foot
masts at both ends to clear some obstructions.
I plan on using 24 dB gain parabolic antennas, both for their gain, as
well as for the narrow beam-width (which I assume should help limit
"outside" contact with the link). I also plan on placing the AP's in
a weatherproof box on the antenna mast adjacent to the antenna and
using POE to get power to the units, and just a short pigtail between
the AP and antenna.
Does anyone know if there is a hack for the D-Link 2100 AP (for
increasing the power)?
According to the formulas I've been pointed to, the D-link units at
32mw should handle the link, even including consideration of fresnel
zones, but I want the links to be solid (even in rain if possible),
and I'd like enough signal strength to get better than "b" throughput
speeds since real-time monitoring of multiple cameras will take a bit
of bandwidth. I'd prefer to avoid the extra expense, complexity, and
likely illegality of adding amplifiers to these units.
One of the main reasons I'm looking at the DWL-21000 is the fact that
it handles WPA (or so they say), as well as the link type I want to
use. There is a remote possibility that I will eventually want to use
one of the sites as point-to-multipoint (with a different antenna),
although the other site will never be used for anything other than
point-to-point. I've never used D-link wireless equipment, but have
always had good luck with their wired products.
Are their any other units I should be considering before the D-link
units? Any brands/models anyone would recommend?
I figure if I eventually want to use vpn tunneling between the 2 sites
I will still need routers at each end that support this? The networks
at each end are a mish-mash of different versions of Windows,
including ME, W2K, and XP, and due to certain software requirements,
need to remain in their current bastardized configurations.
Any info is appreciated, and thanks for reading this tome.
