Abstract: A method comprises a control device encodes a control command in a first management packet, wherein the encoding of the control command the first management packet is identifier by a predetermined identifier; transmits the encoded first management packet to a plurality of target devices. A target device determines whether a first management packet received from a control device includes a predetermined identifier; decodes the first management packet based on a predetermined decoding scheme if the first management packet received from the control device includes the predetermined identifier to obtain a control command; encodes a response to the control command in a second management packet; and transmits the encoded second management packet to the control device. The control device decodes the second management packets received from at least one of the plurality of target device, wherein the second management packets include dedicatedly encoded response in response to the control command.

Abstract: An intelligent mobile phone module is described. The intelligent mobile phone includes a main antenna, an assistant antenna, a switch, an RTR6275 chipset, a triplexer, and an RFR6500 chipset. The main antenna can receive and transmit quad-band GSM signals, CELL850 signals and PCS1900 signals. The assistant antenna can assist to receive the CELL850 signals, PCS1900 signals and GPS1500 signals. The switch is coupled to the main antenna for selecting a desired input or output signal for the main antenna. The triplexer is coupled to an assistant antenna for selecting a desired input signal for the assistant antenna.
