RE: [EXTERNAL] Re: [WIRELESS-LAN] Antenna mounting suggestions

[Letts, Richard J]

I'm wondering if any campus has had success in designing wireless into the 
architectural specification?

Just as crime prevention through architectural design and landscape design 
strives to reduce crime by providing subliminal or overt cues that affect 
movement throughout a building isn't external wireless something that ought to 
be taken into consideration for modern buildings where Wireless and 5g antenna 
should be considered as ubiquitous and essential as power outlets and lighting 
fixtures.

Retro-fitting these design elements into completed buildings is always a hack 
and been the source of more battles with university architects on any campus 
I've worked on than anything else. (which reminds me, I need to go look at the 
stealth sample 4G antenna installed on the top of a building completed recently 
- that project has been going on so long half the architectural team has left.)

As we move through Covid-19, we've seen a huge uptick in the need for outdoor 
wireless - from zero support to 'how quickly can you get it working in these 20 
locations'. Once C19 is on the wane we're probably going to be asked to remove 
the steel poles and other temporary structures we've lashed to railings and the 
suchlike around campus. Frankly google has not been much help searching for 
stealth/camouflage solutions we might deploy in the long term.

Thank you

I need to re-visit the Building 1 situation.  We have put wall-mounts as a 
quick-fix.  The problem is the initial install.  We're trying to do as much of 
this in-house as possible.  The antenna would need to be between on the 3rd 
floor (toward the top of that) to clear the treeline, so we're looking at 35' 
above ground.  That's why we started looking at the roof again.  It's much 
easier to access.  Given our winters, I just want to keep anything that may 
need maintenance out of the snow and away from the edge of the building.

By the way, as far as the Library - there's no chance to put anything on the 
side of the building.  You know construction these days - form over function.  
100% glass curtain walls.  There's only a 1" gasket between panels.

The library is an excellent candidate for a non-penetrating roof mount.  If you 
google it you'll find many options.  Don't get crazy with the size or you'll 
have to have a structure engineer make sure the roof can handle the spot 
loading.  I did the wind load calculations and I think a 100MPH wind could 
result in 23lb of lateral load on an AP-375, so there's no need for tons of 
ballast.  Also, put a pad of some sort (usually available where you order your 
mount) between the mount and the antenna to project the roof membrane.

For Building 2, if you're trying to cover that smallish space between the 
buildings I'd definitely recommend wall-mounted panel antennas.  Put the AP 
above the ceiling inside, drill a ¾" hole in the wall, and mount an ant-35 (or 
something similar) flat to the wall outside.  If you paint it to blend in with 
the brick it will almost disappear.

of those buildings has a flat roof with no knee wall or parapet.  The other has 
a parapet that has glass on the outside.  Both are rubber-membrane roofs, so

Building 2:
Library
Flat roof
Rubber membrane
~40" knee wall/parapet
Rubber membrane goes almost to top of knee wall, then is capped with lead and a 
lightning ground
Outside of wall is glass

Our basic philosophy here is to separate the access points and antennas (ie use 
external antennas).  We can't attach anything to the face of the Library 
(Building 2) because of the glass and I don't really want to have to maintain 
electronics over the edge of a building anyway.  So, how are people installing 
antennas on roofs pointed down to cover quads 60+' below?  I'll figure out 
where to  put the AP's and dress in the cables.

Mounting at ground-level isn't going to work.  There is too much sidewalk and 
landscaping that would have to be disrupted.  It'd be a budget-buster.

Again, physically attaching anything isn't going to be acceptable and in 
Building 2's (Library) case, a large weighted sled will encroach on the service 
area for the solar panels.  There will be several antennae on each roof.

Here are photos.  The photo of Building 1 is a few years old.  The angle with 
the rocks isn't the side of the building I'm putting the antennae.  You can see 
that in the 2nd photo.  I just included the 1st photo because it's a better 
view of the roof:



VENDORS:  I'm already working with Aruba and an integrator.  If you have 
mounting suggestions, please let me know, but there is no sales opportunity 
here.

Thanks,

We went with outdoor APs but wall-mounted at about 10'-12' high. Depending on 
locations, we used either AP-365 with short arm mount brackets that extend out 
(AP hangs horizontally), or AP-367 mounted flat against the wall or with a 
slight incline down (we had to get the adjustable brackets cause the regular 
ones were out of stock).

These are smaller than the buckets 27x or 37x series. We are still not at 8x so 
can't use the 37x. And we did take advantage of the buy 3 get 2 free promotion 
- Since they all have to be the same type, we got 5 of each.

Since these tents get temporary power, another option was to run data to them 
and mount the APs inside the tents or on temporary poles - like it's done at 
conventions. But this way, the installation is permanent and the outdoor area 
will get coverage in the future regardless.

spaces is a quad flanked by 2 relatively tall buildings (about 6 stories).  One 
of those buildings has a flat roof with no knee wall or parapet.  The other has 
a parapet that has glass on the outside.  Both are rubber-membrane roofs, so 
mechanical attachment isn’t going to fly.  The building with the parapet only 
has about a 6’ clearance between the wall and solar panels, so I only have 
about 2’ to work with.

Building 1:
Flat roof
Rubber membrane
Roof has a minimal lip before you drop 6 stories
Has a penthouse that is recessed from the side of the building that I can put 
electronics on/in

Building 2:
Library
Flat roof
Rubber membrane
~40” knee wall/parapet
Rubber membrane goes almost to top of knee wall, then is capped with lead and a 
lightning ground
Outside of wall is glass

Our basic philosophy here is to separate the access points and antennas (ie use 
external antennas).  We can’t attach anything to the face of the Library 
(Building 2) because of the glass and I don’t really want to have to maintain 
electronics over the edge of a building anyway.  So, how are people installing 
antennas on roofs pointed down to cover quads 60+’ below?  I’ll figure out 
where to  put the AP’s and dress in the cables.

Mounting at ground-level isn’t going to work.  There is too much sidewalk and 
landscaping that would have to be disrupted.  It’d be a budget-buster.

Again, physically attaching anything isn’t going to be acceptable and in 
Building 2’s (Library) case, a large weighted sled will encroach on the service 
area for the solar panels.  There will be several antennae on each roof.

Here are photos.  The photo of Building 1 is a few years old.  The angle with 
the rocks isn’t the side of the building I’m putting the antennae.  You can see 
that in the 2nd photo.  I just included the 1st photo because it’s a better 
view of the roof:



VENDORS:  I’m already working with Aruba and an integrator.  If you have 
mounting suggestions, please let me know, but there is no sales opportunity 
here.

Thanks,
Brian

Re: [WIRELESS-LAN] Antenna mounting suggestions

[Ricardo Stella]

We went with outdoor APs but wall-mounted at about 10'-12' high. Depending
on locations, we used either AP-365 with short arm mount brackets that
extend out (AP hangs horizontally), or AP-367 mounted flat against the wall
or with a slight incline down (we had to get the adjustable brackets cause
the regular ones were out of stock).

These are smaller than the buckets 27x or 37x series. We are still not at
8x so can't use the 37x. And we did take advantage of the buy 3 get 2 free
promotion - Since they all have to be the same type, we got 5 of each.

Since these tents get temporary power, another option was to run data to
them and mount the APs inside the tents or on temporary poles - like it's
done at conventions. But this way, the installation is permanent and the
outdoor area will get coverage in the future regardless.
