Sandvine announced that ".. it has successfully deployed its Network Policy Control solutions in three North American wireless networks, BendBroadband, FRC/The Blue Zone and Main Street Broadband. All three operators became Sandvine customers in fiscal 2011 and provide fixed-wireless service using a variety of access technologies including WiMAX, satellite, 3G and 4G .. These regional service providers have deployed Sandvine's Fairshare Traffic Management product to help provide quality service. This product helps manage inherent competition for limited network resources so that the best possible quality of experience is preserved for the maximum number of subscribers for the maximum amount of time".
