Abstract

Methods and/or apparatus for communicating and/or using device capability information are described. Device capability information may be broadcast by a device using a first protocol. The protocol may be a beacon signal based protocol. The device information is used to select a second protocol and/or a device configuration to be used to communicate user data.
