Note for integrators:
You might know this as a cellular amplification system. The industry term for it is cellular DAS (Distributed Antenna System). Same concept, better results. This blog breaks it down.
I don’t know about you all, but I’m still recovering from the whirlwind that was CEDIA 2026. Don’t get me wrong, it was a great week. I got to talk shop with Henry Clifford, who runs Cyber Protect in his own home and shared his honest take on it… including the time he had to very briefly disconnect his network to get it onboarded while his family was home. That’s a brave move for anyone with a house full of people who notice the second the Wi-Fi blinks. His verdict? It never knocked out his Wi-Fi. I caught up with Wade Legette about adding cybersecurity to his lineup, where the conversation kept circling back to RMR and how much recurring revenue a security offering can build. And I had a genuinely lively back-and-forth with Carlos Silva and José L. Jiménez about the education gap around cybersecurity, and the simple truth that integrators can’t sell what they don’t understand yet (great points, gentlemen… I’m keeping them in mind as I plan out what’s coming next).
But, alas, when you’re in your ‘ties, fun also wipes you out. So, while I’m recovering, I’m thinking through what really stuck out for me at CEDIA as we spoke to integrators from across the globe about the things that actually matter: what you’re seeing in the field, your biggest frustrations, and what clients are really asking for. And one thing came up more than almost anything else: Wi-Fi calling that just won’t hold, and what it takes to fix it.
It’s easy for clients to assume that Wi-Fi calling issues mean a weak network. But in a lot of these homes, the Wi-Fi is super high quality. Coverage is great. The internet connection is fast. And yet, calls drop. Clients blame the integrator.
Here’s what most clients (and honestly, a lot of integrators) don’t know: Wi-Fi calling isn’t the same as VoIP, and it’s not as reliable. It was designed as a backup—not a primary solution—and it’s incredibly sensitive to handoffs, interference, and network transitions.
It’s not that Wi-Fi can’t handle voice traffic—it absolutely can. But voice over Wi-Fi was designed as a backup, not as a primary calling method.
Take handoffs. When someone walks from the kitchen to the patio, the phone needs to switch from
Wi-Fi to cellular. But most carriers don’t prioritize Wi-Fi calls during that handoff, and some don’t support it at all. The result? The call drops, the client gets frustrated, and the integrator gets blamed.
Even inside the house, carrier deprioritization can sabotage perfectly good networks. Just because
Wi-Fi is fast doesn’t mean calls will hold. Voice packets don’t get special treatment. If the carrier senses congestion or a weak signal, that call’s gone.
And worst of all? Phones often cling to Wi-Fi too long, refusing to hand off even when the cellular signal would be stronger. It’s not smart enough to switch. So the client keeps calling you, thinking something’s wrong with their “network.”
You install the network. You set up the access points. You optimize the streaming, the smart home, the work-from-home stack. You’re the one who built the system—and when something as basic as a phone call doesn’t work, you’re the one they call.
That’s a hard pill to swallow, especially when the issue isn’t your fault. But perception is reality, and for clients, indoor voice reliability is still table stakes. When they can’t use their phones in their own home, they don’t care whether it’s a carrier issue or a handoff glitch.
They care that it doesn’t work.
As one integrator told us: “We’ve done everything right. But if their call drops, none of that matters.”
That’s the real takeaway here. Even in a well-designed network, Wi-Fi calling problems are still going to surface. The structure of the home, building materials, window coatings, and even neighborhood carrier load can all tank the signal—and you can’t fix that with more access points.
So what do you do?
