Re: Wireless for RV campground

What are you basing that on?  Do you know people that have used that?

When I started researching this, I knew nothing about outdoor wireless, so I
started by Googling outdoor wireless.  And by far, the most positive
customer reviews I came found were on that AP and the D-Link DWL-2700AP.

Quite correct is that price says little. The cheapest unit often
ends up costing the most. Some expensive units can also be crap. If
price really measured value, then GM, whose products are designed
using cost controls, would not be losing money on every car.

Reviews are a good place to start. However which reviewer actually
knows why things do and did not work? Better is to start with a long
list of numeric specifications. From spec comparisons becomes obvious
some specific differences. Some hardware selling on price simply will
not provide important numbers. Then go back to those reviews. Which
reviews discuss these differences? That may weed out about half those
reviews. Useful reviews will typically discuss many items that Jeff
has listed - and with numbers. No numbers? Ignore that review.

Your system must support 802.11 B G and N. That is what future
customers will demand. Other advantages means your access point has
more channels AND can will work flexibly around interference and other
connection problems. For example 802.11 B & G really only provide
three overlapping channels AND are routinely interfered with by
portable phones, microwave ovens, and water. Even wet leaves create
problems not found indoors. 802.11 N means additional channels at
completely different frequencies, better solutions to interference
problems, less problems with loss of signal due to other problems such
as propagation (ie ghosting), and other advantages current and
future. 802.11N provides higher speed only because it is less
resistant to radio frequency problems. Problems that may be most
severe in a campground are interference, blocked, and reflected
signals. Problems that hardware can make less problematic by using N
technology - which is also what your future customers will be using.

If an experienced installer also with technical knowledge, then
maybe find a discounted AP sold by tigerdirect that has value. But
tigerdirect customers are often seeking discounts only on price. Can
you identify rare value in that discount brand name? Best is to start
with an AP from known industry benchmarks. Then buy from tigerdirect
only if they also provide it. Don't select because tigerdirect sells
something at a better price - as so many make the mistake of doing.
But I gather, only from your last post, that you plan to avoid that
mistake.

Still unknown is what your loading will be. Can one access point
support 100 users because rarely are more than 10 users on at any
time? How many actual users will be leasing IP addresses? You will
have maybe 100 such questions to answer or to eventually learn the
hard way. You don't need additional surprises from discounted
hardware.

Plan APs where best located (with cables or tubes for future
network expansion) to reduce the number of surprises that will
inevitably occur later. Also learn of important wiring considerations
posted in that other newsgroup.
