Windows 7’s Mobile Broadband enhancements give people a more reliable way to connect to the Internet using a wireless modem. Taking advantage of this feature is just like connecting to any other wireless network, and is done using the View Available Networks feature.
A consistent experience for customers on top of a common infrastructure for partners to build off of enables several benefits including lower support, maintenance, deployment and management costs. It also allows partners to focus on higher-end services instead of having to focus on basic connectivity development.
