I haven’t heard of 5200 until recently. Most devices I’ve heard of are 900MHz, 2.4GHz, and 5.8GHz. So would 5.2GHz have less interference?
we use 5.2ghz
the big disadvantage is you are not supposed to use reflectors on the receiving end, which means to follow the book you can not have a customer more then 2-3 miles away.
I have only had self interference problems on the 5.2ghz (resolved)
i had some out side interference on the 900mhz
the 2.4ghz was to noisy in my area.
i only have one 5.8 site with no problems.
