Abstract: A wireless communication apparatus uses a Wi-Fi system to transmit to another wireless communication apparatus a WiGig switching request frame (F1) requesting that the communication method for communicating with another wireless communication apparatus be switched from the Wi-Fi system to a WiGig system. The wireless communication apparatus uses RSSI when the WiGig switching request frame (F1) was received to determine whether to allow the switch from the Wi-Fi system to the WiGig system, and uses the Wi-Fi system to transmit to the wireless communication apparatus a WiGig switching response frame (F2) indicating the result of the determination.

Abstract: A first connection control part of a first wireless communication terminal apparatus compares a second network identification information included in a response frame with a first network identification information stored in a first connection information managing part in response to the response frame, and executes an authentication process with a second wireless communication terminal apparatus by using an authentication information stored in the first connection information managing part when a second network identification information included in the response frame is matched with the first network identification information stored in the first connection information managing part, and this leads to establishment of wireless connection with the second wireless communication terminal apparatus by a second communication system.

Abstract: The present invention is a method and apparatus for operating a dual-mode radio (DMR) in a wireless communication system. The present invention provides “coexistence” or cooperation of Bluetooth™ and 802.11 devices operating in close proximity to each other within a DMR. The present inventive method and apparatus reduces reception errors and prevents saturation of the Bluetooth™ devices caused by 802.11 transmissions. The present inventive antenna switching method provides a means for coupling multiple antennas to Bluetooth™ and 802.11 transmit and receive devices. Saturation of the Bluetooth™ receive devices is prevented by electrically isolating the Bluetooth™ receive devices from antennas used by the 802.11 device during 802.11 transmissions. The antenna switching apparatus includes a plurality of switches capable of selectively coupling and decoupling first and second antennas to an 802.11 and a Bluetooth™ device.

The gas is divided by the inlet pipe and introduced therethrough into the dilution tunnel. A plurality of division ratio control nozzles are disposed in the dilution tunnel immediately downstream of the outlet of the inlet pipe for ejecting for ejecting a pressurized dilution gas toward a position downstream of the outlet of the inlet pipe.
