A fully integrated low-power high-coexistence 2.4-GHz ZigBee transceiver implemented in 90-nm CMOS technology is demonstrated. The two-point direct-modulation with a fractional-N synthesizer is adopted in the transmitter architecture. The transmitter can provide high output power of + 9 dBm and excellent error vector magnitude of 5.1%. The direct conversion is used in receiver for simplicity and-97-dBm minimum receiver sensitivity is achieved. Current consumptions for a TX at + 9-dBm output power and for an RX are 28.4 and 15.4 mA, respectively. Excellent coexistence is presented through wireless local area network interferer rejection performance. © 2014 IEEE.


Patent
RadioPulse and Intellectual Discovery Co. | Date: 2014-04-29

According to an aspect of the present invention, a smart home appliance device comprises: a controller for controlling an operation of a smart home appliance; and at least one communication module for transmitting/receiving data on the basis of a command of the controller, wherein the controller transmits an access request message to a consolidated authentication center, receives an access response message corresponding to an access request, transmits a pairing request message including device information of the smart home appliance device to the consolidated authentication center, and receives a pairing response message corresponding to the pairing request message.


Patent
RadioPulse and Intellectual Discovery Co. | Date: 2014-04-29

According to an aspect of the present invention, a data communication method between a battery-operation device and a smart home appliance (HA) in a home area network may be provided. The data communication method comprises: acquiring information of a battery-operation device from data mirroring device by smart HA; transmitting first message with the battery-operation device as final recipient to data mirroring device by smart HA; storing first message and first message identifier corresponding to first message according to type of first message by data mirroring device; initiating operation according to predetermined cycle and transmitting second message to data mirroring device by battery-operation device; inserting first message identifier into response message corresponding to second message and transmitting response message by data mirroring device; and first determination step of analyzing first message identifier and determining whether to make a request for the original first message by battery-operation device.
