We just made this decision in regards to two new res halls.  We opted for 
cables only where we need them now.  The logic is that the pathways and 
telecom rooms are sized in such a way that these cables can easily be added 
later if needed.  Had the new buildings been like most of our res halls, 
where new cabling can only be added with major construction work or surface 
mounted conduit installed onto ceilings (Can you say ugly?), we would have 
gone with a cable in every room.



FWIW, I expect to put an AP in every room eventually, even though I don’t 
know exactly what will drive it or when it will happen.  My two leading 
scenarios are: 1) chip advances and the need for spectrum push WLANs into to 
60Ghz and an AP at that frequency can’t cover more than one room, or 2) the 
ever-increasing need for bandwidth requires us to get all connection using 
256QAM, which is unlikely to work reliably through walls.

Depending on how you are running the cable, you could run it to each room, 
but with the possibility of pulling it back to put APs in hallways instead, 
or to reposition. If you have drop ceilings you can leave like 10ft service 
loop to allow freedom of moving them within the rooms. Etc, etc. These might 
allow you to defer the decision, or to change your mind later based on real 
life results.

I tend in this direction because two of our Resnet buildings have proven to 
be "interesting" with regards to wireless penetration and performance. I 
wish we had left some flexibility in those cases.

Since cabling tends to have a 15-20 year life cycle, and can be expensive 
and disruptive to install, why not just run a cable to each room while you 
have the opportunity? Then you can use your survey tools to decide where to 
place the AP's. This gives you the option of reconfiguring down the road if 
that doesn't work out. It also gives you the option of adding more density 
if necessary. There will be multiple generations of wireless technology 
during the lifetime of the cable and the agility added by the additional 
cable could come in handy.

All,

Last year we cabled our campus classrooms and administrative offices with 
CAT6a preparing for the deployment of Wav 2 802.11ac. We are about to begin 
Phase II of the cabling project in our residence halls and we are looking 
for input from others on whether to plan for one AP per room or trust our 
survey tools. I expect most of you will say "it depends" and we understand 
the complexities of building construction. We have deployed 70 Wav 1 APs as 
a Proof of Concept (POC) testing them in different types of building 
construction but would like to hear other's experiences in particular to 
residence halls. Thank you for your help.
