Yep, looks like you're hitting the wall. We aren't lucky enough to push 3 meg here, the most is usually 1 so again, all depends on your customer base.
I'd say if you already have 35 on that one AP, just splitting it into 2 180 degree sectors will just cost you cash as soon as you gain a few more customers. You already have 35 pulling it down, sounds like if you just do 2 180's, if split evenly (and it never will be) that would put you to where you probably want to be for smooth delivery but not much room for more growth. I'd go with 3 120's and a 433AH with 3 cards on it, one per sector. I have a few like that and it works fine for what I do but again, I only dole out 1mb per sub typically. I've also been upgrading some of my remote AP's to one 433AH with only one radio installed and an Omni. The anticipated upgrade path is to just add a sector or 2 and radio card as needed to the point where I have 3 sectors. Keeping the Omni of course until the third sector is needed. That's something someone already suggested doing and I like the economics of it.

Most are still able to get that, but we're seeing a decline on how many can pull 3meg. At peak times, we've seen it to where users aren't able to get much over 1meg, but that's not happening very often right now. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Robert West Sent: Wednesday, December 02, 2009 8:23 AM To: 'WISPA General List' Subject: Re: [WISPA] Sectors Yeah, how much bandwidth are you passing to those 35 customers, Jason?
