They should have never made the LR models. Louder radios don't work with 
today's mobile clients. It's antenna or nothing. 

The pricing is old as well. It hasn't changed since it debuted. 

A platform that manages handoffs would mitigate that issue. Mobile devices 
really suck in that regard.

I have had this same behavior at my UniFi pilot site. What I discovered in my 
case was a combination of bad behaviors in both the UniFi unit and Android. 



Long story short Android really wants to hang on to a WiFi signal as long as it 
can and does not seemingly scan for other signals when connected. If it sees 
even the slightest bit of a signal from the access point it's connected to it 
doesn't give it up. I can replicate this behavior on every Android device I 
have where I can walk across a building and pass through 2-3 other "cells", 
even others on the same channel, and still see my device connected to the AP I 
started on in the UniFi control panel until it completely loses signal. 


This behavior then interacts poorly with UniFi in that it seems to be very 
willing to keep trying to get the data through to the distant client and queues 
up everything else until it either succeeds or possibly times out. 


Presumably if ZHR worked this would effectively work around the issue, but as 
already noted it has its own issues that reduce its utility in a crowded 
environment. Our solution has been to stop using the "Long Range" units and 
install more small cells to minimize the impacted area if this does occur, plus 
ensure that any Android devices are set to sleep their WiFi when the display is 
off (this is often set by default). The customer we were testing with had a few 
tablets that needed to be on most of the time, but they switched to Windows 
devices for unrelated reasons and basically eliminated the problem. 


There is apparently some way to have the APs drop clients that are below a 
certain signal threshold now, but I haven't looked in to it in a while as it 
hasn't really been an issue.

Overall my experience with UniFi is positive, if you have relatively simple 
needs they'll usually get the job done. You'll probably need a few more access 
points than you would with another solution, but they're generally a fraction 
of the price so it still often works out. If you need your wireless to get 
fancy or handle a high number of clients on a single AP look elsewhere. Needing 
to work on 5GHz also changes the value equation as those units are 
significantly more expensive than the plain 2.4GHz 802.11n units.

Did you figure out why it was dropping out? All of it dropping out? Just some

I had a bad experience with it one time at a tradeshow environment. 6 access 
points setup for public wifi. The radio levels were quite good in various areas 
of the tradeshow however traffic would keep dropping out at random intervals as 
soon as about 300 users were online. It wasn't my idea to use UBNT but it 
definitely turned me off of their product after digging into their gear... 

Again as someone pointed out, for residential and perhaps SOHO applications it 
can probably work well - and in my opinion it's priced for that market.

What problems have you had with UBNT? 

It's zero hand-off doesn't work on unsecured networks, but that's about the 
extent of the issues I've heard of other than stadium density environments.

Dear nanog community 

I was wondering if you can recommend or share your experience with APs that you 
can use in locations that have 300-500 users. I friend recommended me Ruckus 
Wireless, it would be great if you can share your experience with Ruckus or 
with a similar vendor. My experience with ubiquity for this type of requirement 
was not that good. 

Thank you and have a great day
