off for the other. for instance, in a 2x2 system, if two unique data streams are transmitted then the handler er can use MIMO to decode the two streams (no diversity gain ). if only one stream is transmitted then transmitter cocould use transmit Beamforming and the specified er cocould use MIMO to combine the copies of the signal from both chains and improve the range (no multiplexing gain ). Q. Can 802.11n APS deliver the promised multi-hundred megabits throughput with a mix of 802.11n and leg

other network devices are physically damaged, the damaged network adapter will continuously send a large number of packets to the switch, many of which are invalid, A large number of useless data packets may cause information transmission delay and network congestion, resulting in broadcast storms and slow lan network speeds.
