| 20110164522 | Estimation of Position Using WLAN Access Point Radio Propagation Characteristics in a WLAN Positioning System - A method for estimating position using WLAN access point radio propagation characteristics in a WLAN location based service is provided. A location-based services system has a plurality of Wi-Fi access points in a target area. The Wi-Fi access points are positioned at geographic locations and have signal coverage areas. A method of characterizing at least one of the Wi-Fi access points comprises determining the geographic location of the Wi-Fi access point, dividing the signal coverage area of the Wi-Fi access point into at least one section, and determining radio propagation characteristics for each section. The radio propagation characteristics of each section characterize a radio channel of the Wi-Fi access point, and the characterization can be used in a location algorithm. | 2011-07-07 |
| 20110164523 | METHOD AND APPARATUS FOR IMPROVING NOISE POWER ESTIMATE IN A WCDMA NETWORK - A method for adjusting power in a mobile terminal is disclosed and may include determining a total transmit power control (TPC) command for a downlink channel based on a plurality of TPC commands. The plurality of TPC commands may be calculated based on a plurality of control channels. The transmit power may be adjusted based on the determined total TPC command. The plurality of control channels may include a dedicated physical channel and a common pilot channel. Noise power may be determined for each of the plurality of control channels. A TPC command may be determined based on the plurality of control channels. A reliability weight value may be determined for each of the plurality of TPC commands, based on the determined noise power for each of the plurality of control channels. | 2011-07-07 |
| 20110164524 | RADIO ACCESS POINT TESTING APPARATUS - In a case where reception power in a radio access point is high by external noise, the normalcy of the radio access point is tested. In order to judge the normalcy of the radio characteristic of the radio access point, a test is performed through the calling connection between a testing access terminal in the radio access point and a predetermined device. An RSSI is measured before and after the transmission of a test signal. When the RSSI exceeds a threshold value, the path loss of a reverse link connected from the radio access point to the testing access terminal is increased by an attenuator. Then, reception power in the testing access terminal decreases. Thus, initial transmission power in accordance with the reception power from the testing access terminal is raised and the calling connection of the testing access terminal can be performed even under the external noise. | 2011-07-07 |
