Impact of in-building renovation on existing DAS, and how to approach it
In recent months we did maintenance work on existing DAS at different venues - both before and after renovations (upgrading interior, adding walls, or various other activities). Depending on the extent of these renovations, if not properly coordinated, it is quite possible to fall into different kind of service impacting problems. We were asked by one of our clients to put together a generic process to address issues related to renovation at any generic site where there is currently a DAS.

Real purpose of a DAS
The real purpose of DAS is to provide joy to the customer while she is on her phone.
Well... we cannot guarantee joy of any conversation, but our goal is to make sure the phone (i.e., the network supporting the phone), does not become a source of consternation. No choppy sound! No static in the line! No long call set up time! You don't have to raise one leg and tilt 45 degree on your left side to get a good connection. We don't want you to keep uttering that famous phrase like a broken record, "Can you hear me?"
We want the phone to become invisible during your conversation - so that you can just focus on the latest Justin Bieber gossip. And if you do decide to make that fake static sound to avoid talking to your boss or mother-in-law; we just want you to know... we had nothing to do with that. When you hang up the phone, we want you to think about the conversation you just had, and not start cursing the phone.
We don't need you to worry about all those KPI parameters - RSSI, RSCP, Ec/Io, link budget, propagation plots, Uplink-Downlink mumbo jumbo! We got that!
We just want you to have a great calling experience, that's what the phone was made for anyway!

Indoor geo-tagging application for DAS: recent progress
Traditionally, drive test data is tagged with latitude and longitude data. The end result is nice visual of RF signal parameters on a heat-map on Google Earth for example.
When it comes to indoor RF data collection, technology is little primitive from the perspective geo-tagging. Regardless of the equipment you are using, whether a JDSU (Drive Test E6474A Wireless Network Optimization Software), or Commscope's Invex walk test unit, when you are indoor you will have to click on the floor plan every few seconds to show where you are so that the data can be plotted accordingly. This is not automated geo-tagging.
Indoor navigation technology, however, is evolving rapidly. I can see indoor geo-tagging coming to a RF software sooner than later. Indoor navigation technologies such as Smartsense or IndoorAtlas are not just on drawing board or conceptual phase, designers actually have working models. So it's just a matter of time when we will see these incorporated in different DAS tools.
