Abstract

Wireless access network selection is contemplated. The selection process may include arbitrating use of a plurality of wireless networks according to their performance capabilities. The performance capabilities or parameters may be identified from information broadcasted from the wireless networks. Mobile devices capable of wirelessly connecting to the networks may identify the performance capabilities prior to connecting to the wireless networks, thereby enabling the mobile devices to more efficiently identify suitable networks.
