20090070468 | COMMUNICATION SYSTEM AND COMMUNICATION METHOD - In a case where a first relay device | 03-12-2009 |
20090161600 | Wireless slave unit - In a network area of a wireless network managed by a wireless master device, a wireless slave device performs wireless network communication with another wireless slave device connected by wire to a terminal, and wired network communication with a terminal connected by wire to the wireless slave device. The wireless slave device includes a wireless reception unit ( | 06-25-2009 |
20090168707 | RADIO COMMUNICATION DEVICE, BAND SETTING SYSTEM - An object of the present invention is to provide a wireless communication device that can receive a content by securing a band as much as possible, if a predetermined band is required to be secured when the content is received by wire. The wireless communication device judges whether or not the predetermined band necessary for receiving the content can be secured with a wireless master device. When it is judged that the predetermined band cannot be secured in the judgment, the wireless communication device switches a connection destination from the wireless master device to which the wireless communication device has been connected to a different wireless master device that can secure a predetermined receiving electric field strength. | 07-02-2009 |
20090238108 | RELAY DEVICE - A relay device receives transfer data from a transfer-source terminal and transfers the received transfer data to a transfer-destination terminal via relaying performed by another relay device. When the transfer data is received, the relay device establishes direct communication with the other relay device if information regarding the other relay device is attached to the received transfer data. If information regarding the other relay device is not attached, the relay device attaches information regarding itself to the transfer data and transfers the resulting transfer data to a wireless control station. | 09-24-2009 |
20090238196 | NETWORK SYSTEM AND RELAY DEVICE - when a network system of the present invention performs a bandwidth-guaranteed communication, a terminal device collects information on one or more relay devices on a path to another terminal device via a bandwidth request packet transmitted to the another terminal. When the bandwidth cannot be allocated, a detour path is searched according to the collected relay device information so as to perform the bandwidth-guaranteed communication via the detour path. | 09-24-2009 |
20100232415 | CONTROL DEVICE, TERMINAL DEVICE, AND COMMUNICATION SYSTEM AND COMMUNICATION METHOD, USING THE SAME - A terminal device ( | 09-16-2010 |
20110093593 | WIRELESS COMMUNICATION SYSTEM, COMMUNICATION TERMINAL, MANAGEMENT TERMINAL, COMMUNICATION METHOD, AND INTEGRATED CIRCUIT - A beacon is transmitted and received among a plurality of terminals STA. A terminal STA which transmits the beacon is assigned as a representative terminal MSTA which manages a group, and a terminal STA which receives the beacon is assigned as a belonging terminal SSTA of the group. The representative terminal MSTA obtains identification information from the belonging terminal SSTA and stores the identification information. Then, when receiving an AP beacon from a management terminal AP, the representative terminal MSTA collectively transmits, to the management terminal AP, the identification information of the representative terminal MSTA and the belonging terminal SSTA. The management terminal AP performs an authentication procedure, by using the collectively transmitted identification information, for each of all of the communication terminals which form the group. | 04-21-2011 |
20110096679 | CONTROL DEVICE, TERMINAL DEVICE, AND COMMUNICATION SYSTEM - Provided is, a wireless network that conducts wireless communications having superior latency and power-saving performance, while avoiding interference wave influences by using multiple channels. Besides conducting communications with wireless communication terminals | 04-28-2011 |
20110294429 | COMMUNICATION DEVICE AND COMMUNICATION METHOD - The communication device ( | 12-01-2011 |
