Abstract

A wireless multimedia handset can include one or more of wireless system support, a platform to handset features, and multiple features. The multiple features may include, by way of example but not limitation, multiple-antennae, multimedia storage with advanced search capability, a high fidelity sound system, peer-to-peer networking capability, seamless handoff capability, instant hotspot capability, and ultra low power operation such that the handset is capable of operation without recharging by operating solely on solar cells.

Claims

1. A wireless handset device comprising:

a plurality of wireless interfaces, wherein, in operation, a first one or more of the wireless interfaces are used to simultaneously operate in a first wireless system, and second one or more of the wireless interfaces are used to operate in a second wireless system;

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 network;

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.

2. The device of claim 1, wherein simultaneous operation over the first wireless system and the second wireless system is supported at same or different frequencies.

3. The device of claim 1, further comprising antennae respectively associated with the plurality of wireless interfaces, wherein simultaneous operation over the first wireless system and the second wireless system involves assigning a first one or more of the antennae to a first frequency and a second one or more of the antennae to a second frequency.

4. The device of claim 1, further comprising a multiband radio and multiband antennae, wherein simultaneous operation over different frequencies is supported by the multiband radio.

5. The device of claim 1, wherein simultaneous operation over different frequencies is supported by time-division.

6. The device of claim 1, wherein the handoff engine facilitates seamless handoff of a voice over IP (VoIP) application between the first wireless system and the second wireless system.

7. The device of claim 1, wherein the first wireless system is Wifi and the second wireless system is cellular, wherein the handset operates as an access point in the Wifi network with the cellular network serving as an access point backbone network.

8. The device of claim 1, wherein the first wireless system is Wifi and the second wireless system is Wimax, wherein the handset operates as an access point in the Wifi network with the Wimax network serving as an access point backbone network.

9. The device of claim 1, further comprising a power management engine capable of reducing power consumption by at least about 50% using advanced power management algorithms and multi-antenna power optimization.

10. The device of claim 1, further comprising a power management engine capable of reducing power consumption by at least about 70% or more using advanced power management algorithms and multi-antenna power optimization, and shutting down non-essential functions and circuits.

11. The device of claim 1, further comprising solar cells, wherein the handset supports an application indefinitely based only on recharging from solar cells.

12. A voice recognition system comprising:

a language model embodied in a computer-readable medium, wherein, in operation, the language model is trained with user input;

a DSP frontend, wherein, in operation, the DSP frontend extracts features from an acoustic signal;

a wireless interface;

a speech recognizer, embodied in a computer-readable medium, coupled to the language model, the DPS frontend, and the wireless interface, wherein, in operation, the speech recognizer uses features extracted from an acoustic signal by a DSP frontend and dictionary translation assistance received across the wireless interface to recognize a query in spoken language;

an index engine, embodied in a computer-readable medium, coupled to the speech recognizer, wherein, in operation, the index engine receives the query from the speech recognizer, and uses the query, as well as metadata, to generate search criteria;

a search engine, embodied in a computer-readable medium, coupled to the index engine, wherein, in operation, the search engine uses the search criteria to search for a content file and, if a match is found, the content file is played.
