you announcement is not in line of what cambium is used to do... you are playing the ubiquity game on this, as per my understanding
up to 200 mbit/s : I wonder on lab conditions?
up to 20 km : this is dependent of AP antenna at the 1st and based on the gain of the CPE, will it be at lowest modulation? (so useless for a wisp)
also, for the 2nd model force 200 you claim up to 40 km, double of model 180, this is 6 db more in link budget but the antenna gain is only 1 db more...
Same applies for the max output power: you claim 30 dBm output power but this is for the lowest modulation which is useless for the wisp. A wisp requires maximum modulation almost all time to exploit a successful network and it is limited to 18-23 dBm depending on band...
Said that, I have to say I'm very happy with ePMP1000, they are performing very well, I have 9 towers and growing with ePMP1000. I'm using integraded CPEs alone or with reflector dish at the moment. Depending on the cost of new models I'll move on them.
Finally, special thanks to the developers for fixing the memory leak on radius reject: no issues, no customer complains since then.
cambium has always noted a max range on documentation, they differ in the since they provide link planning tools and excel sheets to forcast what you can expect from the radios at a given distance. the big backhauls have ranges over 100 miles, but its a given you're not parking at max modulations at that distance. cambium always recommends using a link planner so you know what to expect and what products to select to fill the need, I'm sure that recommendation will never change.
max power is irrelevant from a legal stand point. in PTMP setup, the FCC (and other regulatory bodies) regulates your ERIP, as well as max TX power. 36 DB is your ERIP limit for the upper band, 33 in 5.1 and some variation in the middle which is lower, cambium is keeping you legal as they are required too. (PTP links have slightly different rules for TX powers) if you notice in PTP mode, the power does adjust some and will adjust the TX power in relation to the antenna gain. ( TX power can go up to 30db) being angry at a vendor for keeping hardware in regulatory compliance doesn't make any since.
aggregate capacity in the field does hit 200 meg, of course that requires every CPE in max modulation. not always relistic, but very possible. 20km out would be -78 db, assuming clear Fresnel, if noise isn't a problem, that will provide MCS 11 (following FCC regulatory limits in the upper band)
