I ran a carrier’s in-building wireless business. The notice on your desk is not a technical update. It is the end of a subsidy, and the math behind it tells you exactly how much leverage you have left.
By Darlene Braunschweig, Founder, Resolution Wireless
In the mid-2000s I ran the in-building distributed antenna business for a national carrier. We put base stations in office towers, hospitals, and arenas at our own expense, and we did it for one reason: the people inside those buildings were our subscribers, and when their phones did not work indoors, they churned. Indoor coverage was a retention cost. We funded it the way we funded billboards.
That is the deal that is ending. Understand why, and the notice on your desk stops being a mystery.
Why the subsidy made sense, and why it stopped
Three things changed. First, the carriers’ indoor problem got solved for them. Wi-Fi calling, better handsets, and denser outdoor networks meant that a mid-rise office in 2026 gets tolerable coverage from the street in a way it did not in 2010. The carrier’s churn risk went down, and so did its willingness to pay.
Second, the equipment aged out. Most carrier-funded DAS installed between 2008 and 2018 was designed for low and mid bands under 2.7 GHz. The spectrum that carries 5G today sits at 2.5, 3.45, and 3.7 to 3.98 GHz. Much of that installed base cannot pass it. From the carrier’s chair, the building has a coverage system for the network of 2015 and the carrier is being asked to keep paying for it.
Third, the carriers moved the cost. They pushed indoor funding toward neutral-host operators, who charge the building instead, and toward the property owner directly. What used to be a carrier line item is now a building line item. The notice is how that transfer is delivered.
The carrier is not walking away from your tenants. It is walking away from paying for them.
What the notice actually does
Strip the language and a carrier DAS notice does one of three things. 1.) It says the carrier will remove its base station on a date. 2.) It says the carrier will stop maintaining the base station but leave it running until it fails. Or 3.) It says the carrier will stop paying a neutral host or vendor that has been running the system on its behalf. Each one leaves the cabling and antennas in your ceilings untouched and leaves your building with a signal source problem.
None of them is a shutdown, but all of them are a deadline.
How much leverage you have
More than the notice implies, and it depends on three facts you can establish this week.
1. How valuable is your building to the carrier? A trophy tower with 4,000 daytime occupants, a hospital, or a venue still justifies carrier investment, and a notice to that building is often an opening position rather than a final one. A 150,000-square-foot suburban office does not, and no negotiation changes that.
2. What else does the carrier want from you? If the same carrier has a rooftop macro site on your building, or wants one, or has fiber in your riser, you are in a two-sided conversation and should treat the DAS notice as one term in it.
3. What does the agreement say? Most carrier DAS was installed under a license, not a lease. The license usually gives the carrier the right to leave and says nothing about what it owes you on the way out. Some do require removal at the carrier’s cost or transfer of equipment to the owner. Read it before you respond to anything.
The mistake owners make in the first thirty days
They take the first meeting with whoever calls. The first call after a carrier notice comes from a vendor offering to manage the problem for a monthly fee. That vendor did not create the notice, but it has been waiting for it. The question you should be asking in the first thirty days is not who will run your system, but what is your building worth to the carriers now, and what does that let you demand.
