I'm not using Canopy at the moment - I had bought a trial kit, ended up selling it. I'm using Mikrotik right now. How are you doing with concurrent calls per sector? I'm talking about rolling out a network _mostly_ dedicated to VOIP, even some customers without data at all. Some customers would have as many as 8 to 10 voice lines. For customers who want more I would simply use a PtP link for them. With all VOIP the real bandwidth cuts to 4.5Mbps on Advantage according to Motorola's white papers.
I'm also concerned with scalability, if I have 6 x 5.7 Canopy APs on a tower, I need 100' of vertical space to co-locate a 5.2 set. Most of my towers aren't even 100' tall. Trango is not only dual polarity, but dual band as well. Nothing suggests you can't put them all in close proximity as long as they are in different polarizations / bands when close by. I wonder if IAX2 trunking would allow more VOIP calls over the same data bandwidth due to packet size / aggregation? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Eric Muehleisen Sent: Monday, July 02, 2007 3:05 PM To: WISPA General List Subject: Re: [WISPA] Trango & VOIP Doug, I will second Forrest's comments. We have been running VOIP on Canopy for several years now will great success. The key is setting the high priority queues and DiffServ settings. We also tagged VOIP traffic in a high priority DHCP VLAN. We've found that PPPoE encapsulation really struggles with VOIP.
