Carrier WiFi

Carrier WiFi is operator-grade WiFi that a service provider offers its subscribers as an extension of the mobile service. Unlike basic guest WiFi, it connects devices automatically and securely with Passpoint — no login — for a cellular-like experience, and supports carrier use cases like WiFi calling and data offload. It's designed to extend coverage and capacity at scale, seamlessly.

Carrier WiFi gives subscribers fast, reliable connectivity where cellular struggles — especially indoors and in dense areas — with automatic, secure connection and no manual login. A consistently good experience across more places increases satisfaction and makes the service stickier, which reduces churn. Adding WiFi calling and offload further improves everyday reliability, reinforcing the subscriber's reasons to stay.

WiFi calling lets subscribers make voice calls and send texts over a WiFi connection instead of the cellular network — useful where cellular signal is weak, such as indoors. Carrier WiFi provides the seamless, secure WiFi connectivity that WiFi calling relies on, so subscribers stay reachable and connected in more locations without dropped calls or dead zones.

Passpoint lets devices discover and authenticate to trusted WiFi automatically and securely, with no captive portal or manual login — a cellular-like handoff. OpenRoaming, from the Wireless Broadband Alliance, extends that automatic, secure connection across a global federation of networks with one trusted identity. Together they let carriers deliver seamless WiFi far beyond their own footprint.

Cellular signals weaken indoors and in dense areas, exactly where demand is high. Carrier WiFi fills those gaps by connecting subscribers automatically to WiFi, improving indoor coverage and adding capacity where the cellular network is under strain. This offloads traffic, boosts the everyday experience, and lets operators serve more users well in the places people actually spend time.

Yes. Carrier WiFi uses Passpoint-based authentication with encryption rather than open networks, so connections are secure and automatic. Cloud4Wi's platform is SOC 2 certified and built for GDPR and global compliance, with a data-compliance framework governing how data is handled. Subscribers get a protected, seamless experience, and providers meet the security and regulatory standards their networks require.
