Man, it sounds like you need a business plan to get out of that town. Your
network, I mean. You'll most likely need to either sell out, buy out the
other WISP, or branch out either with your wireless network or establish a
POP in another town. Do one of these things before you get burned out.
900MHz won't be like 2.4GHz. You won't have the distances which means more
APs and backhauls and your CPE will be more expensive for those shorter hops
as well. This I'm sure you've heard. Use the omnis for your area...seems
appropriate. No geek war needed there. ;)

Subject: Re: [WISPA] 900MHz Omni and gain
Let me add a little about what I have to work with. There are 4036 people
in the township which is my main coverage area (I fork out a little, but
the number are inline with these). 2,288 have access to DSL and Cable.
This leaves 1748 people to go after. How many of those want broadband? I
just did a quick google and the only number I saw said 30% of rural
Americans have broadband. So I'll go with that for my number of who wants
it. 30% is about 500 people. I guess this means my township that is 36
square miles has almost 15 subscribers per square mile that are ripe for
the picking. And then add the fact that there are 2 total WISPs in this
area. Cut the subs in half. I have 7 subs per square mile to go hook up.
Wait, it seems like 50% of my site surveys fail due to the darn trees, at
least I can still get those 3.5 subs per square mile. :)
Now that I have given a little more info, do you guys still recommend
sectors?

Problem is I might only get 10-15 subs at these sites in the next year.
Lets say I can buy 10 APs. I'd rather have 10 sites with omni's than 5
sites with 180* sectors.
At 15 subs a site I'd have 150 subs on 10 omni's at $35 a month. That is
$5250 a month.
If I sectorize 5 sites with 15 subs that is 75 subs and only $2625 added
to the monthly income.
Back to reality. I can't afford 10 APs.....but still, I don't see
sectors as being such a great thing. What is the point of doubling the
cost of a pop for no gain of subscribers?
Back to my question. If a guy wanted to use omni's for 900. What is a
good choice?

We have a legacy 900 omni at 750' AGL. It really reaches out and touches
remote customers, but it is visible to every other cell in the region
and
affects channel planning. Stick to sectors, they might be more
expensive up
front but long term you will have more options.

Due to the eirp limits at 900 (36dB total) your antenna choice really
should
take into account the radio gain first.....
Having said that, a lot of people put in the high gain 900 omni antennas
and
don't seem to have much trouble with them.
I agree with the sector idea though.
The 900 that I'm using now is trango. They have almost got the full
eirp
built right in to the radio/antenna system as it comes from the factory.
The down side is that it takes 6 ap's to cover 360*. That can get
spendy.
Especially if you pay rent per antenna.
As a rule, we are sectorizing more and more sites these days. Even the
ones
out in the sticks. There are too many other users out there showing up
all
of the time.

Hello Brian,
No more then 8db in my playbook anymore. And horz. if at all possible.
Sectors on 900 is the best way to go too.
I got an Antel 11db with downtilt that I would sell if you really want
a
vertical omni. Heavy duty antenna.
