Nextel is launching Wi-Fi service aimed at business travelers in partnership with Boingo Wireless and Wayport. The service with all three partners will let customers access the Internet from hotspots at airports, hotels, convention centers, retail stores and other locations. The arrangement also gives Nextel customers Internet access in 150,000 hotel rooms where Wayport’s wired-Ethernet connections are available. A related service, Nextel’s Wireless PC Access, will provide coverage beyond current hotspots. This service is available with the company’s im240 PC card. Connection software creates single-click access to both services, the company said.
