Abstract
A hardware-centric medium access control (MAC) device comprises a control plane module and a hardware media access planed module. The control plane module is for providing control functions of the hardware-centric MAC device. The hardware media access plane module communicatively coupled to the control plane module is for performing real-time data communication functions without requiring a microprocessor.

A voice communication device comprising:
- a microprocessor;
- a memory communicatively coupled to said microprocessor;
- a wireless communication module communicatively coupled to said microprocessor, said wireless communication module for receiving and transmitting voice traffic over a wireless connection and comprising:
- a physical layer (PHY) device;
- and
- a hardware-centric medium access control (MAC) device implemented as a portion of a system on a chip (SOC) communicatively coupled to said PHY device and conditionally activated from a shutdown state by said PHY device, wherein said MAC device is configured to perform real-time voice communication functions using the SOC, said hardware-centric MAC comprising:
- a control plane module for providing control functions of said hardware-centric MAC device;
- and
- a hardware media access plane module communicatively coupled to said control plane module and for performing real-time data and voice communication functions without requiring a microprocessor, said hardware media access plane module comprising:
- a beacon process module to receive and to filter out unwanted voice traffic packets in hardware without use of other portions of said hardware-centric MAC or using said microprocessor, such that said microprocessor remains in a sleep mode during beacon processing by said beacon process module;
- a de-fragmentation engine communicatively coupled with said beacon process module and for providing real-time de-fragmentation, in gate logic, of received voice traffic packets that are not filtered out by said beacon process module;
- an encryption/decryption engine coupled with said de-fragmentation engine to provide on-the-fly encryption/decryption of voice traffic packets with real-time logic based key retrieval merged with on-the-fly fragmentation and defragmentation;
- and
- a fragmentation engine communicatively coupled with said encryption/decryption engine and for providing real-time fragmentation, in gate logic, of transmit voice traffic packets.
