Time Warner Cable customers who do a lot of travel – especially by way of General Mitchell airport here in the city – may want to check out the new roaming Internet access service.

Time Warner Cable (TWC) teamed up with Boingo Wireless to launch Passpoint roaming access, allowing secure wifi network connections in thousands of locations throughout the U.S.

The service, in use now at 25 of the busiest airports, is available for TWC Internet customers whe also subscribe to Boingo. The new web surfing option was announced this week.

"Passpoint technology provides significant value to our customers. Our Passpoint roaming integration with Boingo will keep our users connected to this advanced technology during their travels, helping us provide maximum wireless security to our TWC Internet consumers when they’re surfing the Internet out of home," Rob Cerbone, VP of Wireless Product Management for Time Warner Cable, said in a statement.

Boingo subscribers can access thousands of TWC Passpoint-enabled hotspots in cities such as New York, Austin and Kansas City. The service will expand to additional cities including Los Angeles and Charlotte in early 2015. Boingo customers currently have access to TWC’s more than 60,000 hotspots in major cities across the U.S.

"The launch of reciprocal Passpoint roaming in the U.S. marks a significant milestone for the wireless industry, but more importantly it makes the best possible WiFi connectivity experience available to even more customers in key locations throughout the U.S.," said Dr. Derek Peterson, Boingo Wireless chief technology officer. "Our partnership with TWC gives our customers truly widespread access to simple, seamless and secure WiFi in key markets nationwide."

Boingo’s Passpoint-enabled hotspots and TWC wifi connections use WPA2 enterprise-grade encryption technology. The roaming experience is similar to how cell phone networks roam now.

To get access, TWC customers should download the TWC wifi Finder app from the Apple App Store, which will then allow them to provision a Passpoint profile on their iOS (Apple-based) device. Their device will then be able to connect to TWCWiFi-Passpoint and Boingo "Passpoint Secure" networks.
