Can MOCN Move the Needle for Enterprise Connectivity? - Inside Towers

After years of encouraging enterprises to invest in their own connectivity solutions, the wireless industry may have finally hit upon a winning formula. Instead of distributed antenna systems (DAS), some […]

New phones have the CBRS (citizen broadband radio service) freqs in them and can use this system, I wonder if the portable mfgs will start doing this.

We've talked a bit with Federal Wireless about this. Several Universities and large industrial/government campuses are doing it. Makes a whole lot of sense.

We've got a large DAS system and recently Sprint has been grumbling about pulling out their macro site, which also feeds the DAS. We think there's some movement in this direction amongst the carriers as it makes a lot of financial sense.

I'd love to see this take off for LMR. I've moved our PD to Harris radios so we have WiFi and LTE capability but no CBRS. Hopefully that gets added down the road.

Technology needs to move on, and this seems to be in the right direction.

All of this in building solution is great for blue sky days, but the biggest flaw in anything is that during an disaster, it can and will become compromised. The entire IFC510/NFPA requirement is nothing more than "cover your arse" building code enhancement that turned up a high profit industry overnight. One structure fire that melts cable and system is offline. Power failure and batteries die. Water ingress from firefighting activities and your EF Johnson is in the dirt. The only real solution for public safety is an on-site repeater on a fire truck or comms vehicle tactically positioned, then hope you don't have a 9/11 where a building collapses and smashes it.

I agree. I feel the whole NFPA in building thing is a waste.

I'm fighting it right now. Fire moving to a fire ground isn't as big of an issue for me. The larger issue is MED and LE calls where they are going into a perfectly good structure and begin having coverages issues because it's not something where an IC would be setup. That's why we've been playing a lot with SmartConnect and getting with the school districts and learning their common SSIDs for tying back in.

Long term, I think I would like to see the DAS systems remain for larger buildings but instead of a BDA go to a micro-site feeding the DAS. What EFJ is doing with the City of Irving on NTIRN (a Motorola system) right now is a real eye opener as to what can be done with ISSI interfaces between the manufacturers so if it gives us the ability to stand up low power DAS sites for larger buildings then it may be the thing to do in the long run.

The problem is RF subsites cost real money. A FutureComm Digital VRS costs around $6000. The FutureComm solves the coverage problem and is much easier to maintain than another RF subsite, ISSI licenses, etc.
Like anything else, when the building is on fire, planes flying into them, flood waters rise, infrastructure burns, floods and crumbles. Ask anyone in Buncombe county, NC.

What does work is deployables and that is what is keeping them alive. This is what we SHOULD be investing in.

What fire dept IC would have his folks in a burning building for 2 hours? I think the IC at the Walmart fire in Indiana pulled everyone out within 20 min of being on scene.
