There is a Procera category for "Malware" which you can use to filter traffic 
which has a malware signature.

Havn't shaped any traffic yet with this procera box. But here is a graph of 
what kind of traffic the clients are using as a whole in one days time. Of 
course Netflix is at top. But i am surprised at how close behind that youtube 
is (shows up as http media stream) Usually at any given time the 
Netflix/Youtube accounts for 50-75% of all traffic running through this box.

[AFMUG] PMP450 in 3.55?

[Jeremy Grip via Af]

I notice looking at PMP450 specs that there are two separate units in 3GHz, one 
for 3300-3600 and one for 3550-3800. Does that mean we’re liable to be able to 
utilize the lower 100 when (if?) we get shared 3550-3650 on that platform?  
They’d be able to implement robust compliant DFS on it—it’s an SDR, right?

Sriram, that brings up my next question. The channel planning model for reuse 
is great for Idealtown, located on a flat plain where one can permit and build 
POPs on a tidy rectilinear grid. (This may be just west of Rolling Meadows).  I 
wonder about the utility of channel reuse in say, Realtown, where the topology 
is quite bumpy, forestation is patchy, and the operator takes what he can get 
in the way of locations for POPs. This is pretty much my situation, and 
probably plenty of other folks’ too.

 

I’m trying to think of a broad rule set for channel planning in those 
conditions. For instance, I’m planning to expand into an area with existing 
structures (silos). In the attached image I’ve modeled coverage in Radio Mobile 
with an RSSI of –66dBm or better at the SM, assuming an ePMP AP/90°sector at 
power limit for max modulation and Force (25dBi) SMs (antenna pattern is just 
an omni for planning purposes). Max cell radius is 6km. This is over actual 
topology, of course, and using a publicly available ground cover (clutter) 
database, so it should be a pretty good prediction of which POP gets best 
signal to a given location. Each POP has its own color, with some reuse where 
it wouldn’t be confusing. (This is RM’s “combined cartesian” coverage, so there 
are plenty of locations where more than one POP can provide better than -66, 
but the POP with the strongest SS gets to put its color on the pixel.)

 

Some of the POPs won’t want a full 4-sector deployment, but many, probably 
most, will. Am I better off, generally speaking, with the recommended 4-channel 
model, with two of the four channels on each POP (and the other two channels on 
the adjacent POP) than I am with the two channel model? And if so, would I just 
maintain the same azimuths for all of the POPs—e.g. channel A always at 0° and 
180° and C at 90°

and 270 ° on POPs 1,3, 5…, then channel B always at 0° and 180° and D at 90° 
and 270 ° on POPs 2,4,6…? Then maybe we could just leave out unnecessary AP 
quadrants on POPs where they weren’t going to do any good.

 

Is there any reason to try the ABAB reuse model if four channels are available? 
Does the necessity of setting Frequency Reuse “Front” and “Back” go away in the 
ABCD model—and can anyone explain just what that’s doing?

 

Whew.

 

Oh, yeah—can you just software switch between the GPS timing signal on the

Hi, 

 

Yes, the GPS chip comes with an internal patch antenna. The internal patch 
antenna is automatically disabled once you connect the external GPS antenna 
(and auto enables when you disconnect the external antenna). If you think the 
radio itself doesn't have clear LOS to the sky, then you can use the external 
antenna and place it elsewhere on the installation to get better LOS to the 
sky. 

 

There are a couple of documents on our support site 
(https://support.cambiumnetworks.com/files/epmp​ ) you can read through that 
will help answer questions about ABAB deployment using ePMP.

 

Thanks,
Sriram

Re: [AFMUG] Cambium Newbie Question

[Jeremy Grip via Af]

Actually, you can select multiple APs (“Fixed Units”) and one target SM 
(“Mobile unit”) and select the “Backcolor” independently for each AP, then do a 
single run (which is pretty processor intensive depending on the pixel 
resolution-I’ve had these things run up to an hour on an 2.5 GHz i5 with 8G of 
RAM ). The cool thing is that the resultant image will color a given unit (1 
pixel, 2x2 pixel, etc. depending on setting) only the color of the AP with the 
strongest signal. If you save the resultant image as a “picture” it will also 
save a .kml file (among other files) in the same location. Now if you have 
generated the image over a pure white background (works best if you just set 
the background ‘picture properties’ to contrast=0%, brightness=100%, even 
using, say, grayscale terrain as background), and then saved the image as a 
picture checking the “white is transparent” checkbox, you have a .kml you can 
open in GE, and adjust the overlay transparency in the image properties. Very 
useful.

Hi, 

 

Yes, the GPS chip comes with an internal patch antenna. The internal patch 
antenna is automatically disabled once you connect the external GPS antenna 
(and auto enables when you disconnect the external antenna). If you think the 
radio itself doesn't have clear LOS to the sky, then you can use the external 
antenna and place it elsewhere on the installation to get better LOS to the 
sky. 

 

There are a couple of documents on our support site 
(https://support.cambiumnetworks.com/files/epmp​) you can read through that 
will help answer questions about ABAB deployment using ePMP.

 

Thanks,
Sriram

the APs come with an antenna for GPS, but its never been clear to me whether 
there is also an internal patch

So would you be able to switch over to the onboard sync remotely? Do you need 
an antenna for each AP for using it? Do you think it’s as precise as using an 
CMM4 (or SyncPipe Deluxe w/Gig Injector) if not as robust? If all POPs are 
sync’d with same Up/Dn ratio and max cell distance and they’re talking to the 
same birds, is it pretty much the same?

.also the PMP100 SyncInjector from Packetflux ought to work with ePMP.  You 
might want the gigE version, but in the real world with a mix of subscribers at 
different MCS levels I'm not sure how likely you are to exceed 100x100.

The CMM4 is a much more rugged beast.  It is expensive, but you are not likely 
to go back and wish you'd bought the cheap one.  

My plan is to hook up the internal GPS and have it available, but also to 
provide sync over power.  Once you are using GPS sync to re-use channels it 
becomes critical that it's always working, so better to have two timing sources 
available IMO.

They have built in GPS if youre on a budget, not sure why alot of people are so
