I'm using a UC520 right now with 2 x AP521 access points. The building is 16,000 sq ft. I have 2 x Cisco 7925G cordless phones, however I have quite a few dropped calls and I think that could be caused by them handing off between networks. I would like to fix this, and also setup a guest WIFI network for the following.
It looks like my options are the following:
1) Buy a WLC526 used for about $150. My understanding is that this supports both Zero-Handoff and guest networks.
2) Buy 2 x Ubiquiti UAP-PRO for about $200 each.
What would you recommend, or would you recommend something else.
