RE: [WIRELESS-LAN] Current state of DAS in Higher Ed?

John,

Outside of my University duties, I’m fortunate to have a fairly busy 2nd career 
as a freelance writer/consultant. This gets me into a lot of NDA, early look 
situations. I’d encourage everyone pondering in-building cell concerns to get 
up to speed on CBRS https://www.fcc.gov/rulemaking/12-354 and to watch for 
coming announcements from WLAN vendors in this regard. It really could be a 
game changer, far beyond anything that’s ever been tried in the spirit of 
leveraging WLAN deployments to assist with bad cell coverage. By week’s end, 
there will be at least one major announcement on CBRS.

Just one more spice for the soup, but a potentially important one.

Hiya -

What is the current state of DAS in Higher Ed?

Are you using DAS systems on your campus?

For coverage or capacity or both?

Glad you did?

I'm interested to hear stories.  We have a few LEEDS buildings that are quite 
Faraday cage-like.  Wonder if we should explore DAS, wait for wifi-calling, or

I think the time for new indoor DAS deployments in most buildings has 
passed.  If you’ve already invested in a head-end, it may be worthwhile to 
expand it.  If you haven’t done it yet, now is not the time to start.  Avoid 
anything you can possibly avoid until Wi-Fi calling and SMS makes indoor 
cellular coverage moot (could be a 3 to 5 years to 90% penetration in some 
markets).  Keep spending low by addressing anything you can’t avoid with OTA 
systems (no head-end) or femtocells.  Improve your Wi-Fi network with what 
you would have spent on DAS.



I don’t anticipate in-building public safety network requirements to drive 
installation of multi-provider systems.  Ignoring any specific or implied 
code requirements that the two systems be separate, supporting multiple 
service providers, technologies, and bands will drive up the installation 
cost and short the system life-cycle substantially over what would be 
required to support public safety alone. On a large scale, the price 
difference will likely continue to discourage DAS for cellular coverage.

Our local laws are now that public safety radios must have the same signal 
inside new buildings as outside, so life safety radio DAS is mandatory for our 
last 3 buildings, as well as anything new in the future.


As far as cellular DAS, we looked into it with a few vendors and were told 7 
figures per building, and since the carriers are pushing everyone to move to 
wifi calling, they won’t work with an institution our size even if we did have 
the money.  Policy makers on campus decided the college does not have an 
obligation to provide cell service so the project died.

We have indoor DAS (iDAS) installed in a few buildings.  It's horrendously 
expensive, and there's pretty much no chance anymore of getting carriers to 
help fund it.  

The ACUTA group just did a series of webinars on cellular technologies and 
forecasting for the future, if you're a member of that organization.  Wi-Fi 
calling is definitely going to play a key role.  

You might also want to look at what local regulations you have for public 
safety radios (police/fire/etc walkie-talkies) - there may be requirements for 
your institution to make sure that those signals can get into these new 
buildings too.

We did an initial investigation of DAS but the costs were described to me as 
“sickenly”expensive so we dropped it.
