Hello – our interest in Mimosa wireless products was already high based on field reports from fellow WISP operators. Thus far, we are pleased with the test results, which compare very favorably to our existing wireless outside plant – UBNT.
Your support for the extended spectrum in 5.9GHz and above made us VERY interested. We have a STA from FCC authorizing us to use 5855 to 5925 - a 70MHz chunk.
Frequency selection in the AP must assume that we’d be using 80MHz channel, because the highest freq we can select is 5885 - effectively locking us out of 30MHz of usable frequency space, because we ONLY use 20MHz channels. We find that if we keep our path lengths AP - CPE reasonable, RSSI and SNR high (thank you RF Elements Asym Horns!) in a 20MHz channel we can support 100Mb/10Mb plans all day long, and re-use is great. With 40MHz or larger channels, not so much…downlink is robust - 170Mb or better, uplink falls apart due to RFI / noise issues. So 20MHz is an easy choice to live with.
Is it possible that your devs could build a little more intelligence into the frequency select function on the AP, and gate the selected frequency based on channel size selected, not simply ASSUME that 80MHz operation is going to fly? In our market, with 4 or so competitive WISPs, I can assure you that 80MHz channels are very ineffective. A waste of spectrum, and a blight on the RF landscape.
Any feedback greatly appreciated.
