Solutions for 4. In-building public connectivity / The gap you don’t see ## Everyone in your building has a phone. Not everyone has signal. Every person who walks in carries a phone on AT&T, Verizon, or T-Mobile, but steel-and-glass construction can block the macro network. When coverage disappears, users step outside to finish a call, switch to Wi-Fi, or simply accept it. The result: an invisible population of users struggling to stay connected. **The usual fixes each cover only a slice:** ![Icon connectivity wi fi ink 512](https://celona.io/volumes/images/Icons/Connectivity/Standard/512/icon_connectivity_wi_fi_ink_512.png)Wi-Fi CallingOnly if users enable it ![Icon security 2 factor authentication ink 512](https://celona.io/volumes/images/Icons/Security-and-Policy/Standard/512/icon_security_2_factor_authentication_ink_512.png)PasspointOnly on compatible devices ![Icon connectivity ethernet wired ink 512](https://celona.io/volumes/images/Icons/Connectivity/Standard/512/icon_connectivity_ethernet_wired_ink_512.png)DAS18 months, millions of dollars **Celona offers all three on one platform, deployed together - so everyone has connectivity the moment they walk in.** / How it works ## Three layers, zero gaps Each layer extends coverage to more users. Together, they reach everyone. **Layer 1** ### Wi-Fi Calling *Your widest net, with no user setup required.* **Reaches most users automatically** - Supported by most phones and enabled by most carriers by default - Calls, texts, and data route over Wi-Fi when cellular coverage is unavailable - Celona Wi-Fi provides a managed, visible infrastructure optimized for voice - Automatically serves users connected to Wi-Fi with Wi-Fi Calling enabled [ Learn more about Celona Wi-Fi ](/wi-fi) **Layer 2** ### Passpoint *Seamless and automatic - no login, no password.* **Extends coverage beyond Wi-Fi calling** - Devices authenticate to your Wi-Fi using carrier credentials (Hotspot 2.0) - No SSID to select, no portal, no password to enter - Seamless outdoor-to-indoor connectivity where carrier Passpoint agreements are in place - Native Passpoint support extends automatic connectivity to more users [ Learn more about Passpoint support ](https://celona.io/contact-us) **Layer 3** ### Neutral Host (CBRS) *For everyone else - including users you’d never know you were losing.* **Catches everyone else - any handset, no opt-in** - Reaches users who keep Wi-Fi off for security, policy, or bad past experience - Covers carriers and devices without Passpoint, or users who haven't enabled Wi-Fi Calling - CBRS + MOXN delivers native cellular for AT&T, Verizon, and T-Mobile from one infrastructure - No app, settings, or opt-in - any handset gets full signal when it enters the building [ Learn more about Neutral Host ](/moxn) / Why Celona Celona is the only vendor that delivers all three coverage layers on a single managed platform. No more juggling separate vendors for Wi-Fi, Passpoint, and Neutral Host. Celona Orchestrator gives you one cloud-based operating model across every layer, access point, and device. ![Icon engagement one transparent price ink 512](https://celona.io/volumes/images/Icons/Engagement/Standard/512/icon_engagement_one_transparent_price_ink_512.png) ### One contract, every operator Sign once with Celona.

Beyond ensuring reliable public cellular connectivity within our facilities, we envision utilizing this platform to establish a secure private wireless network dedicated to essential medical technologies, including clinical communication, patient monitoring, and clinical video streaming. **Christian Lindmark, VP/CTO · Stanford Health Care** [ Read the Stanford Health Care case study ](https://pages.celona.io/hubfs/Asset/Stanford-Health-Care-Case-Study.pdf) > When I looked at the cost/benefit, it was a no brainer. We implemented the Celona private 5G network because it solved AGV connectivity downtime issues that we were having with Wi-Fi. Adding the Celona Neutral Host feature on top of the same infrastructure without adding additional technology or devices was perfect, and we find our employees taking advantage of the neutral host network for both their personal and corporate devices. **Luca Chichiarelli, Head of IT · Del Conca** / Key resources [ ![Resource default product documentation](https://celona.io/volumes/images/Resource-Defaults/_800x450_crop_center-center_75_none/47333/resource-default-product-documentation.webp) Product Documentation NEW ### Solution Brief: AerLoc One identity, one security model across every radio, security built into the converged wireless fabric.
