He is talking about 430 which may go a bit farther, although now with MIMO-A 
mode they are about equal.

Part of the problem is the 450 AP won’t let you set the xmt power for max 
allowable EIRP with a low gain antenna.

To maximize distance, I might use 450 instead of 430, and a 10 MHz channel in 
5.7.  450 starts out with 6 to 8 times the capacity of FSK, so even cutting the 
channel width in half, you still have a 3 to 4 times capacity increase, and you 
gain 3 dB of system margin which should get you out to 5 miles instead of 3-4 
like Sean says.  You could even go to a 5 MHz channel.

If you find the omni isn’t giving you enough capacity, maybe you have a cluster 
of high bandwidth users in one direction and you add 1 sector.  Eventually if 
you get enough subs, you can fully sectorize.

There was a rumor from AF about a Lite (10 SM) AP from Cambium, upgradable with 
a license key.  If true, this would make sectors an easier decision.  Although 
you still have to buy antennas for them.

you will only get about 3 maybe 4 miles out of a 450 with an omni

  I know I know, don't use it. But in this case, I have to. Plus, we only have 
25 Customers at this site on a FSK 5.2 AP. And I am looking for the same 
coverage area (roughly 8 mile radius).

  The FSK does surprising well on a 9 dbi L-Com antenna at 8 miles.


  1st column is uptime. I rebooted the AP yesterday.


  Yesterday I installed the AP with a UBNT 10 dbi OMNI and the Range sucked. 
-82 at 3.1 miles. It's what I had on hand.


  I am looking for twice the distance at -79 or better. This is a SUPER Rural 
area with no noise.

  thanks
