The disadvantage of 5.8, is that you never know what you are gonna get until its up in the air, because you dont know the noise floor you'll see.
The advantage of millimenter wave (I consider 24Ghz millimeter wave) is that the beam width is extremely narrow, and few people use it because of the distance limit, and difficulty to mount stationary. As well, it only allows low power ptp for everyone using the band, so you never have some unexpected high power PTP link or wide beam PtMP showing up to cause you interference like in 5.8G. So its often considered inteference-free, allthough it is possible to get interference. In general you can expect to get full radio speed. Millimeter wave can go far, out in the dry desert. But in high rain zones, it does not. I never recommend over 2 miles with 24Ghz and 2ft dishes in Mid East coast rain zones. For 20km and high capacity, I'd still suggest Licensed, since licensed gear is getting more affordable every day, and there again, you get full radio speed, because you know the noise floor and link budget in advance. With UBNT MIMO (dual pol) and 20Mhz channels, 5.8G, and a noise free channel, 2ft dish, you can get as much as 80mbps HDX. But I never count on more than 40mbps HDX, until after I know the noise floor for the link, considering typical noise floors I often see in my areas.

I have a UBNT Rocket M5 on a 20.3km link signal with 10MHz channel size is about -60dBm on both ends and can only do about 30Mbps one way. Will the Exalt perform better? I need at least 50Mbps full duplex. Thanks for any suggestions. Julius Igugu Lightning Networks On 9/27/2011 7:57 PM, Me wrote: 5.4 GHz has to be open. Use an Exalt link on 5:4 and you can get up to 440 aggregate with an 80/20 traffic split.
