Microcells normally have good SNR. Add 802.11AC into the mix and you
have very good performance without the crappy latency hit.

Entirely not true spoken by a WISP that has up until this

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...

Give me TDMA Atheros with sectors over omnis on

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?
