Cambium event last Monday.

455 is likely to be what they use for the new 900 variant.

the 450AP will be phased out, however.

    At some point (soon?) the 450 SM needs a processor boost.  Is that what the 
PMP455 is all about?

      On the existing hardware?  At one time there were hints about 256QAM and 
40MHz channels, hence the GigE interface on the AP.  They delivered on 256QAM, 
I haven’t heard about 40 MHz in awhile, I doubt 80 MHz is under consideration.  
Also they needed a lot of firmware optimization to get throughput to a single 
SM up to what the RF can do now.  So I’d guess even 100 Mbps to a single SM 
would take new hardware.

      Well the Mimosa will deliver 620 megabits or so to two clients at the 
same time, so 1,200+ total from one AP.

      How much room is there for growth in 450? *shrugs* How long has it been 
out and how much growth have you seen thus far?

      Is the 450 still only 20mhz and under?   If they even can or do up it to 
like 80mhz like mimosa is going to do, how close could the 450 get to 600meg

        For us, the biggest issue is the replacement cost of the 450.  NOT the 
initial cost, that is what it is, but we are in the lightning capital of the 
world.  Sometimes we can repair everything that gets hit and sometimes on a 
direct strike, we can’t repair any of it.  On most towers, we deploy 5 Ghz and 
2.4 Ghz, so 8 APs each.  Some are only one frequency band, so then there are 
only 4.  Say those 4 APs are supporting 50 customers at $ 45 each… $ 2250 / 
month. (most towers are a less than that and some are more).  So, if I lose $ 
8K in APs ($ 2000 x 4) in one evening, I am looking at least 4 months of lost 
revenue just to replace those APs (not counting labor, etc.)  We have had 
commercial, well-grounded towers that get hit twice in a season, so that’s 8 
months (probably more like 10 months loss in real business terms) per year.  
That makes NO sense to play that game.  



        And, again, a lot of towers have two frequency bands, thus 8 APs.  We 
have had 4 commercial towers out of 18 with total losses this year on the APs.  
Thankfully, the used market on 100 series APs is very low cost, so not nearly 
as big of an impact.  



        So, with ePMP APs (while maybe not as good as 450APs) I can at least 
cut my losses by 80%.  That’s a big deal !



        Unfortunately, that reality forces my hands.

            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.

                  TJ, 



                  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.

                  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.
