Abstract: A wireless station has a media access controller (MAC) and a concurrent association manager. The concurrent association manager concurrently associates the wireless station with two or more wireless coordinators. Each wireless coordinator forms its respective wireless network. The concurrent association manager sets the wireless station in a sleep mode operation with respect each wireless network and detects a selection for operation with respect to one of the wireless coordinator.

Abstract: A radio frequency (RF) transmitter is coupled to and controlled by a processor to transmit data. A physical layer circuit is coupled to the RF transmitter to encode and decode between a digital signal and a modulated analog signal. The physical layer circuit comprises a high rate physical layer circuit (HRP) and a low rate physical layer circuit (LRP). The low rate channels generated by the low rate physical layer circuit (LRP) share a same frequency band as a corresponding high rate channel generated by the high rate physical layer circuit (HRP).

Abstract: A radio frequency (RF) transmitter has a plurality of digitally controlled phased array antennas coupled to and controlled by the processor to transmit data. The processor is to enable one or more antennas to be turned off during a use of the apparatus to reduce a power consumption of the apparatus.

Abstract: A multiple-input multiple-output (MIMO) system can transmit on multiple antennas simultaneously and receive on multiple antennas simultaneously. Unfortunately, because a legacy 802.11a/g device is not able to decode multiple data streams, such a legacy device may "stomp" on a MIMO packet by transmitting before the transmission of the MIMO packet is complete. Therefore, MIMO systems and methods are provided herein to allow legacy devices to decode the length of a MIMO packet and to restrain from transmitting during that period. These MIMO systems and methods are optimized for efficient transmission of MIMO packets.
