Yea, I covered that in one of my articles.  I just didn’t see everyone sitting 
around the campfire singing Kumbya.  Another reason I don’t worry about GPS.   
My next article covers my main reason.

        Entirely not true spoken by a WISP that has up until this point used 
Mikrotik and Ubiquiti in rural and suburban markets with 12 WISP competitors.

        And now your completely out of spectrum and can't deploy anything new.  
I suppose the good part for you is nobody else can do anything given the amount 
of noise your making.

                You just hit the nail on the head why we have never considered 
deploying 450 (and similar) in the past:
                
                By the time "you" (relative term) have the cashflow to pay for 
those sectors, "we" (another relative term, for people deploying UBNT or 
similar) have already thrown up 4-6 shielded sectors and at least 10 clients 
per. If we don't think we can hit a decent sub density or at least make the 
site a valuable repeater, then we don't go there.

                        I prefer sectors too but math doesnt always work out. 
I'll put the omni in to get the site up and once the customers are there change 
it to sectors. The 450 platform is very easy to drop sectors in and have the 
existing clients link right up. I have a couple sites with existing customers i 
am dropping a two sector 450 system in with 120 segree KP antennas. cant afford 
any more sectors than that per site right now...

                                No difference between the 3 different 
frequencies bands (other than NLOS range) as far as the product itself they are 
all the same animal. 2.4ghz NLOS is slightly better than 3.65ghhz. They all 
function the same and have the same expected throughputs per channel width. 
They all use the same firmware and i love the interface being the same across 
all 3. The only major difference is the 5ghz is V/H versus slant on the other 
two. That just translates to the 5ghz omni being ALOT smaller and lighter. 
There are some places that i wish the 2.4ghz woulda been V/H because of the 
omni size but overall I am still very happy with the 2.4ghz 450.

                                Any pros and cons on 450 between 2ghz, 3.65 and 
5?  Any differences at all? Range vs throughput? Obviously 2ghz penetrates 
better, 3 is licensed and 5 has more spectrum but anything else? All bands are 
open for me

                                I started the spring deploying 450 in 2.4ghz, 
5ghz, and 3.65ghz and then middle of the summer deciding i had to"try" some 
ePMP because the cost was so low I couldn't resist.... I can say now that I am 
fairly certain I will probably stick with the 450. There are many small reasons 
that when I considered them all i came to this conclusion. Here are my reasons: 

                                 

                                1. ePMP latency starts to go up quickly once 
you have more than 10 clients on an AP. Once you get over 20 clients the 
latency is pretty much 25-30 ms. Cambium was honest about this at the road tour 
and they noted if you want the best latency to stick with the 450.

                                2. Sync between the two platforms is not there 
yet. If you have adjacent towers on the different platforms that can see each 
other you won't have sync.

                                3. No remote spectrum analyzer for clients. 
This is HUGE for when the clients fire up their wireless camera and baby 
monitors and trash the whole spectrum.

                                4.No burst bucket on CPE's 

                                5.EPMP Interface is SLOWWW. Cambium explained 
at the tour they were offloading alot of processing power to the PC you are 
viewing the interface with and i can't be taking a quad core machine up a tower 
to work on these radios and do site surveys. I am working with a Panasonic 
Toughbook and takes FOREVER to log into the EPMP radios.

                                6. Fore some reason site surveys are a PITA 
with ePMP. Think its a combination of many factors here... slow interface one 
of them...

                                7. EPMP in 5ghz DFS band has really low power 
output. Something like 13-14db. When using an omni antenna you can't get 
maximum legal EIRP out of the ePMP.

                                8. 450 link tests and SM modulation is pretty 
stable and predictable. EPMP seems like its all over the place. I don't think I 
have yet seen EPMP linktest get full up or down outside of a lab environment.

                                 

                                There might be other reasons but I'm pretty 
tired and was heading for bed.
