How is your experience with the ePMP 2.4GHz? Are you using the Cambium sectors for example? Bandwidth, throughput as expected or better? What's your typical speed?
We've had excellent results with ePMP 2.4... similar performance to ePMP on 5GHz... although typically there's more noise. We almost always have to use a 10MHz channel, and we use GPS sync at every site to we can squeeze more out of the spectrum by using back to back frequency reuse and smaller 5MHz guard bands between channels.
To give an example... we have a 2.4GHz AP using a 20MHz channel with 35 clients on it, hitting peaks as high as 75mbps download, and 6mbps upload during busy hours.
We really like Cambium's OEM ePMP 2.4GHz Sector... it's very high quality, and has an excellent front to back ratio, making it good for frequency reuse situations... I think the antenna is made by MTI. We've also used some of KP's dual band antennas (5+2.4GHz) with mixed results. I think if you're just wanting to deploy 2.4 or have the tower space, then the OEM antenna *feels* like it works better. If tower space is at a premium, then the dual band KP's can save you some serious money in terms of tower rent.
With the new 4.4.1 firmware we're seeing about 10% performance increase over 3.5.6 firmware, due to short GI and LDPC optimizations. Some other people are reporting up to 15% performance increase. We now run 4.4.1 on 100% of our ePMP network... for both AC and N based radios.
