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 wehave 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 UBNTor
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 densityor 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...

I've noticed a lot of PMP operators are deploying omnis (presumably
because they can't afford 4 APs. Give me TDMA Atheros with sectors
over omnis on anything any day.

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.

Kurt,
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
Thanks

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.

I haven't been keeping real up to date on current
generation ptmp offerings but we have a new site going
up and I need to decide pretty quickly on some
equipment. For the guys who have been using both 450 and
epmp do you have any pros and cons ? Any reason to spend
the extra money when epmp seems to have the same if not
better performance , sync, etc?
My gut says 450 is going to be my best long term
solution but with all of the positive epmp feedback it's
hard to justify the extra money?
