20150136470 | SELECTION METHOD FOR STRONG WIND REGION COMPOSITE INSULATOR BASED ON STRUCTURE PARAMETERS, AND COMPOSITE INSULATOR - A selection method for a strong wind region composite insulator based on structure parameters, and a composite insulator are disclosed. When a selection is made among a plurality of composite insulators according to the selection method, structure parameters of the composite insulators are measured first, and then the selection is made according to certain ranges of the parameters, a selected composite insulator is tested, and it is found that it may withstand strong wind climate environments where the highest wind speed reaches 50 m/s. The composite insulator is a composite insulator having corresponding structure parameters. The selection method is easy to operate and implement. When the composite insulator is applied to a strong wind region where the highest wind speed reaches 50 m/s, the problem of violent oscillation of umbrella skirts or tear of the umbrella skirts does not occur, and the composite insulator may still operate reliably. | 05-21-2015 |
20150255194 | SELECTION METHOD FOR STRONG WIND REGION COMPOSITE INSULATOR BASED ON INTRINSIC FREQUENCY, AND COMPOSITE INSULATOR - A selection method for a strong wind region composite insulator based on a intrinsic frequency, and a composite insulator are provided. When a selection is made among a plurality of composite insulators according to the selection method, a intrinsic frequency of a composite insulator to be selected is measured first; if the composite insulator is an unequal-diameter umbrella, the intrinsic frequency of a large umbrella skirt in the composite insulator is measured; if the composite insulator is an equal-diameter umbrella, the intrinsic frequency of any umbrella skirt in the composite insulator is measured; and then a composite insulator is selected according to the intrinsic frequency, wherein the composite insulator whose intrinsic frequency is greater than or equal to 45 Hz is selected. The composite insulator is a composite insulator having corresponding structure parameters. Study is carried out on wind-resistant performance of an insulator when applied to a strong wind region to obtain the selection method, and the method is easy to operate and implement. When the composite insulator is applied to a strong wind region where the highest wind speed reaches 50 m/s, the problem of violent oscillation of umbrella skirts or tear of the umbrella skirts does not occur, and the composite insulator may still operate reliably. | 09-10-2015 |

20130070746 | TRANSMISSION METHOD FOR SUPPORTING DATA COMPRESSION - A wireless communication network includes a network device and a terminal device. The network device sends a first message indicating a data compression algorithm supported by the network device, receives a second message identifying a data compression algorithm supported by the terminal device, and sends a third message to the terminal device upon receiving the second message, the third message identifying a negotiated data compression algorithm. | 03-21-2013 |
20140301378 | METHOD FOR IMPLEMENTING NEIGHBOR DISCOVERY PROTOCOL IN A WLAN - A method for implementing neighbor discovery protocol in a wireless local area network (WLAN) and an access point (AP). In the method, the AP prestores the logic group of each wireless client associated to the AP, determines the logic group of a neighbor discovery protocol related message when the message is received by the AP, and transmits the neighbor discovery protocol related message to at least one wireless client included in the logic group of the message via a unicast mode, respectively, according to prestored information relating to the logic group of each wireless client associated to the AP. | 10-09-2014 |
20150133099 | MIGRATION OF A VIRTUAL ACCESS POINT - A microcell wireless network includes at least one access controller (AC) and multiple physical APs in wireless communication with mobile stations. The AC configures an independent virtual AP for each mobile station in the microcell wireless network on a first physical AP associated with the mobile station. When migration of a virtual AP configured for a mobile station is required, the AC transferring the virtual AP from the first physical AP to a second physical AP according to a predetermined policy. | 05-14-2015 |
20150312830 | PROMOTING WIRELESS LOCAL AREA NETWORK (WLAN) ROAMING - The present disclosure describes promoting roaming of a wireless terminal in a wireless local area network (WLAN). The AP obtains signal quality and/or data transmission quality of the wireless terminal periodically, and determines whether the obtained signal quality and/or data transmission quality of the wireless terminal satisfies a predetermined threshold. Upon determining that the predetermined threshold is not satisfied, the AP proactively sends a probe response frame to the wireless terminal. The probe response frame notifies the wireless terminal of a wireless signal strength of the AP to promote roaming to a neighbouring AP. | 10-29-2015 |
20150334571 | ESTABLISHING WLAN ASSOCIATION - A method of establishing network connection between a network device and a WLAN is disclosed. The method includes: determining whether there is previous security association between the network device and the WLAN at the time of requesting for network association, and establishing a new security association between the client device and the WLAN using security data generated in the course of establishing said previous security association if there is said previous security association. | 11-19-2015 |
20150341789 | PREVENTING CLIENTS FROM ACCESSING A ROGUE ACCESS POINT - According to an example, a detecting AP may determine whether a rogue AP is in the wireless network. In response to a determination that a rogue AP is in the wireless network, the detecting AP may obtain a wireless channel of the rogue AP and according to the wireless channel of the rogue AP, the detecting AP may transmit on the wireless channel of the rogue AP, a channel switch instruction to a client associated with the rogue AP by simulating an identity of the rogue AP. The channel switch instruction is to instruct the client to switch to a designated new channel. | 11-26-2015 |
20160044585 | ESTABLISHING A LINK IN A MESH NETWORK - A mobile mesh point is mobile with respect to a first connecting mesh point and a second connecting mesh point. While the mobile mesh point has a mesh link with the first connecting mesh point, the mobile mesh point scans for a connecting mesh point with which it may establish a mesh link. On detecting the second connecting mesh point, the mobile mesh point may establish a virtual mesh link between the mobile mesh point and the second connecting mesh point by exchanging messages between the mobile mesh point and the second connecting mesh point via the first connecting mesh point. The messages exchanged comprise messages to establish a real mesh link. The virtual mesh link may be transformed to a real mesh link between the mobile mesh point and the second connecting mesh point. | 02-11-2016 |
