Celona, a private 5G networks company, has expanded its neutral host solution to support AT&T subscribers, improving in-building cellular coverage for millions of users. Previously certified with T-Mobile, Celona Neutral Host now enables seamless connectivity for AT&T customers when they enter a building covered by a Celona 5G LAN network.

The solution, powered by Celona’s cloud-based Multi Operator Exchange (MOXN), securely connects devices to public mobile operator networks. Any smartphone or tablet with AT&T or T-Mobile SIM/eSIM can automatically authenticate and connect over the Citizens Broadband Radio Service (CBRS) spectrum, with voice and data sessions routed transparently to the respective carrier’s network.

“Celona Neutral Host represents a significant advancement in enterprise connectivity and is an even more compelling solution now that AT&T has joined,” said Mehmet Yavuz, Co-founder and CTO at Celona. “Due to their rigorous test and certification process, AT&T can ensure that their customers receive the superior cellular service they expect. And enterprises simply sign one contract with Celona. It’s fast, simple and cost effective.”

Available immediately in the U.S., Celona Neutral Host can support up to five mobile network operators (MNOs) simultaneously, as well as dedicated private wireless networks for enterprise use. The MOXN platform simplifies network operations by eliminating costly hardware and securely tunneling mobile traffic to MNO core networks.

Compared to traditional Distributed Antenna Systems (DAS), Celona’s solution is faster to deploy, more cost-effective, and provides enterprises with greater control over in-building cellular services. It can be integrated with existing Celona private wireless networks or deployed as a standalone neutral host solution.

Private wireless neutral host solutions are particularly suited for healthcare facilities, large retailers, offices, hotels, and universities. Stanford Health Care plans to expand its private 5G neutral host network across multiple buildings in the San Francisco Bay Area.
