Latest / The 5G Podcast with Fexingo: Wireless Networks, Carriers, and Mobile Infrastructure / How 5G Is Quietly Transforming the Hotel Industry
Transcript
- Lucas: Luna, have you ever checked into a hotel and the Wi-Fi just... crumbled under the weight of everyone in the lobby trying to upload vacation photos at the same time? Luna: Oh, absolutely. It's almost a rite of passage. You're standing at the front desk, juggling your phone and your ID, and the network just gives up. Lucas: Right. And the hotel usually blames 'high demand' and shrugs. But that frustration is actually a really good entry point for what 5G is quietly doing inside the hospitality industry — not just faster guest Wi-Fi, but a full re-architecture of how a hotel operates. Luna: So we're talking private 5G networks inside the building? Not just the carrier signal bleeding through the walls? Lucas: Exactly. And the poster child right now is Marriott. In 2025, they deployed a private 5G network at the JW Marriott Austin — that's a big convention hotel, over 1,000 rooms. They partnered with a company called Boingo Wireless, which has been doing distributed antenna systems in airports for years, to build out a dedicated 5G core inside the property. Luna: So instead of everyone fighting for a slice of the public cellular tower or the hotel's Wi-Fi, the hotel gets its own slice of spectrum. That sounds expensive. Lucas: It is not cheap to set up. But Marriott's bet is that the operational savings and guest experience lift make it worth it. Let's look at one specific use case: check-in. Right now, when you walk into a big hotel, the front desk staff are tethered to wired terminals. With a private 5G network, every staff member carries a tablet or a handheld that's connected at sub-10-millisecond latency. They can check you in from anywhere in the lobby, process payment wirelessly, and issue a mobile key — all without the guest ever waiting in a line. Luna: And the mobile key part — that's been around for a while with Bluetooth, but Bluetooth can be finicky. 5G should make that instant, right? Lucas: That's exactly the upgrade. With Bluetooth Low Energy, the door sometimes takes a second or two to unlock, and if your phone's in your pocket at a weird angle, it might not work. A 5G-connected lock — using the network's ultra-reliable low-latency slice — can unlock the door in under 200 milliseconds. It's not a huge difference on paper, but in practice, it eliminates that awkward pause. Luna: And for the hotel, they don't have to replace batteries in locks as often, because 5G IoT modules can be more power-efficient than constantly scanning for Bluetooth. Lucas: Exactly. But the bigger operational win is probably in staff communication. Most hotels still use two-way radios or even pagers for housekeeping and maintenance. With a private 5G network, every employee gets a push to talk app on a smartphone that works over the private network — crystal clear audio, no interference, and you can seamlessly escalate to a video call if a housekeeper needs to show a maintenance issue to someone remotely. Luna: And that replaces the old PBX phone system too? The one in every room? Lucas: That's a huge part of the ROI. A traditional hotel room phone is a surprisingly expensive piece of infrastructure to maintain — the wiring, the PBX hardware, the licensing. Marriott has been phasing them out anyway, but with a private 5G network, you don't need a separate voice system at all. Guests can use their own phones to call the front desk via a 5G VoIP app, or use a smart speaker that's on the network. One less thing to maintain. Luna: And what about the convention business? The JW Marriott Austin hosts big conferences. That's a lot of bandwidth demand all at once. Lucas: This is where private 5G really shines. In a typical convention space, you might have thousands of attendees all trying to stream video, use event apps, or live-post on social media. Wi-Fi can handle that, but it degrades as more devices connect. With a private 5G network using licensed or shared spectrum, the hotel can guarantee a certain bandwidth per attendee. Boingo's deployment at the JW Marriott uses CBRS spectrum — that's the Citizens Broadband Radio Service band in the US — which gives them dedicated capacity that doesn't compete with public cellular. Luna: So the conference organizer can tell exhibitors: 'You will have five megabits per second per device, no matter what.' That's a selling point. Lucas: Exactly. And it opens up new services. For example, the hotel can offer real-time location analytics — anonymously tracking which sessions are most crowded, where attendees are lingering, to optimize F&B staffing. That data is much more accurate with 5G than with Wi-Fi triangulation. Luna: But let's talk about the small hotel. The boutique inn with 30 rooms. They can't afford to build out a private 5G core. So does this only apply to the big chains? Lucas: That's a great question. For smaller properties, the near-term solution is network slicing from a public 5G carrier. A hotel can buy a 'slice' of a carrier's network that's prioritized for their guests — like a VIP lane. T-Mobile and Verizon have both started offering enterprise slicing products. So a boutique hotel could essentially pay a monthly fee for guaranteed throughput, without any on-premise hardware beyond a few small cells. Luna: So the technology is scalable, but the business case still depends on the hotel's willingness to invest. Let's talk about security — because a private network that handles check-in data, payment info, and room access is a juicy target. Lucas: Security is actually one of the strongest arguments for private 5G. On a public Wi-Fi network, guest devices are on the same logical network as the hotel's internal systems unless there's heavy segmentation. With private 5G, the core network is physically separate. The hotel can isolate guest traffic from staff traffic from IoT sensor traffic at the network layer. Plus, 5G has built-in encryption and authentication that's stronger than typical Wi-Fi security protocols. Luna: And because it's a private network, the hotel controls the authentication. They can revoke a mobile key instantly if a guest checks out early, or if a staff member leaves. Lucas: Right. There's no dependency on the guest remembering to delete the key from their wallet app. The network just rejects the credential. That's a big improvement for security-conscious brands. Luna: You know, this conversation has actually given me a few concrete examples I can use. If today was actually useful to you, the way these stay ad-free is listener support — buy me a coffee dot com slash fexingo. Lucas: Absolutely. It's a small way to keep the show going without ads or sponsors. And if you've ever been stuck in a hotel lobby with dead Wi-Fi, you know exactly why this matters. Luna: Alright, back to the tech. Lucas, what about the timeline? Are we seeing mass adoption, or is this still early adopter territory? Lucas: It's still early. Marriott's JW Austin deployment is one of the most ambitious, but it's a pilot. Hilton has been testing private 5G at a few properties in partnership with Verizon. I expect we'll see more announcements in 2027, especially as CBRS spectrum becomes more widely available and the hardware costs come down. Luna: And the hardware — what does it actually look like? I'm picturing big cabinets in the basement. Lucas: It's getting smaller. The 5G core can run on a server about the size of a pizza box now, and the radios are small enough to mount on ceilings or in drop ceilings. For a large hotel, you might need a few dozen small cells, but the backhaul — the connection to the internet — is the critical piece. Most hotels already have fiber from their property management system, so that's often reused. Luna: So the biggest barrier is really the upfront cost and the expertise to manage it. Hotels don't typically have network engineers on staff. Lucas: Exactly, which is why managed service providers like Boingo and Crown Castle are stepping in. They build, operate, and maintain the network, and the hotel pays a monthly fee. It's a lot like how hotels outsource their Wi-Fi today. Luna: That model makes adoption much more likely. One last thing — how does 5G affect the guest's own cellular experience? If the hotel has a private network, does my AT&T phone work better inside? Lucas: It can. Many private 5G deployments also include neutral-host capability, meaning the private network can connect to all major carriers' cores. So your phone sees the private small cell as a legitimate AT&T tower. That improves indoor coverage for everyone, even if they're not using the hotel's specific services. Luna: So it's a win-win. The hotel gets operational efficiency, the guest gets better connectivity and a smoother experience. Lucas: Exactly. And that's the quiet transformation we're seeing — not flashy, not consumer-facing, but fundamentally changing how a building's digital infrastructure works. I think in five years, we'll look back at hotel Wi-Fi the way we look at in-room phone books: a relic of a pre-5G era. Luna: I'm already looking forward to never having to squint at a Wi-Fi password card again. Lucas: That day might be closer than we think.
