Patent ID: 8090374

Claim:
A wireless handset device comprising: a multiple-input multiple-output (MIMO) radio frequency (RF) system including a multi-band radio and a plurality of multi-band antennae, wherein simultaneous operation with a first wireless system and a second wireless system at the same frequency is supported, and further wherein simultaneous operation over different frequencies is supported by the multi-band radio; a plurality of wireless interfaces, wherein, in operation, a first one or more of the wireless interfaces are used to operate in a first wireless system and a second one or more of the wireless interfaces are used to operate in a second wireless system, and wherein operation in the first wireless system and the second wireless system is simultaneous by using a first subset of the plurality of multi-band antennae for the first wireless system and a second subset of the plurality of multi-band antennae for the second wireless system; and wherein further the plurality of wireless interfaces include a wide-area wireless interface and local-area wireless interface, enabling the device to act as an instant hotspot by serving as an access point for local-area wireless network to connect to a wide-area wireless network by using the first subset of multi-band antennae for the local-area wireless network and the second subset of multi-band antennae for the wide-area wireless network; a peer-to-peer networking engine coupled to the wireless interfaces, wherein, in operation, the peer-to peer networking engine uses neighbor discovery and routing to connect to a peer-to-peer wireless network, and wherein the peer-to-peer wireless network is established based on a list of specific devices with which a user wishes to interact; a handoff engine coupled to the wireless interfaces, wherein, in operation, the handoff engine accomplishes seamless wireless handoffs from the first wireless system to the second wireless system by maintaining connections with both the first wireless system and the second wireless system until handoff is complete, wherein the handoff engine facilitates seamless handoff of a voice over IP (VoIP) application between the first wireless system and the second wireless system; and a power management engine to reduce power consumption in the wireless handset by using a power management algorithm, and multi-antennae power optimization, and shutting down non-essential functions and circuits: and an array of microphones, wherein a weight is assigned to each of a plurality of microphone inputs, depending on one or more performance criteria; and wherein a noise cancellation operation is performed based on the weights.
