Turn Any WiFi Into Your Network
Complete carrier WiFi offload without building infrastructure. Passpoint, OpenRoaming, WiFi Calling, and RADIUS-as-a-Service - everything you need to extend your network reach through WiFi.
Carrier WiFi offload uses Passpoint and OpenRoaming to automatically route subscriber traffic from cellular to WiFi networks, reducing infrastructure costs while improving coverage. IronWiFi provides the complete authentication backend - RADIUS, Passpoint profiles, SIM-based auth, Online Sign-Up, and multi-tenant management - so carriers, MVNOs, and WISPs can launch WiFi services in days without deploying hardware.
The Complete Carrier WiFi Stack
Everything you need to offload, authenticate, and manage subscriber WiFi
Passpoint / Hotspot 2.0
Subscribers connect automatically to any Passpoint-enabled hotspot. No captive portals, no passwords - just seamless, secure roaming like cellular.
OpenRoaming Federation
Join the WBA OpenRoaming ecosystem and give subscribers access to 3M+ hotspots globally. No bilateral agreements needed - federation handles it.
WiFi Calling Integration
Enable VoWiFi for subscribers in buildings, basements, and anywhere cell signal falters. Seamless handoff between WiFi and cellular keeps calls connected.
Online Sign-Up (OSU) Server
One of the few hosted OSU providers. Subscribers auto-provision Passpoint profiles through a simple web flow - no app install required.
RADIUS-as-a-Service
Cloud-hosted RADIUS with EAP-SIM, EAP-AKA, EAP-TLS, and TTLS support. No on-premise servers to maintain. Scales automatically with your subscriber base.
Real-Time Analytics
Session data, roaming patterns, device types, and traffic volumes. Full visibility into how subscribers use your WiFi network.
Who Uses Carrier WiFi Offload?
From mobile operators to fixed wireless providers - WiFi extends every network
Mobile Carriers
Offload cellular data traffic to WiFi at peak times. Reduce congestion, lower infrastructure costs, and improve subscriber experience in high-density areas.
MVNOs
Add WiFi to your mobile offering without building infrastructure. Differentiate from other virtual operators with seamless WiFi roaming for subscribers.
WISPs
Professional cloud RADIUS for fixed wireless networks. Centralized authentication, subscriber management, and bandwidth controls without running your own servers.
ISPs
Offer managed WiFi as a value-add for business customers. Branded portals, usage analytics, and tiered service plans - all from the cloud.
Venue Owners
Monetize your WiFi through carrier partnerships. Let carriers offload through your access points and create a new revenue stream from your existing infrastructure.
The Economics of WiFi Offload
Why every major carrier is investing in WiFi offload strategy
Lower Infrastructure Costs
WiFi offload costs a fraction of adding cellular capacity. Leverage existing venue WiFi instead of building new towers.
Improved Coverage
Extend your network reach into buildings, basements, and dead zones where cellular struggles to penetrate.
Reduced Churn
Subscribers who get consistent connectivity - indoors and out - are less likely to switch providers.
Capacity Relief
Move data-heavy sessions to WiFi and free up cellular spectrum for voice and signaling where it matters most.
OpenRoaming: Global WiFi Without the Agreements
Join the WBA federation and give subscribers worldwide WiFi access instantly

Carrier FAQ
Common questions from carriers evaluating WiFi offload
How do Passpoint profiles work for subscribers?
Profiles are installed via your app, MDM, or our OSU server. Once installed, devices automatically connect to matching Passpoint hotspots - no user action needed.
Do you support SIM-based authentication?
Yes. We support EAP-SIM, EAP-AKA, and EAP-AKA' for seamless SIM-based auth. Subscribers connect automatically using their existing SIM credentials.
How do roaming agreements work?
Through the WBA OpenRoaming federation, subscribers roam across 3M+ hotspots without bilateral agreements. We handle the RADIUS proxy and settlement.
Can we white-label the portal?
Absolutely. Each carrier tenant gets a fully branded portal with your logo, colors, and domain. Your team sees your brand, not ours.
What APIs are available?
Our REST API covers subscriber provisioning, session management, analytics, and billing. Plus webhooks for event-driven automation and Terraform support.
How quickly can we go live?
Most carriers are live within days. Point your access points to our RADIUS servers, configure Passpoint profiles, and you are operational. No hardware to deploy.
Enterprise-grade security and compliance
Launch Carrier WiFi in Days
