The time the radio will be in RX state when RX termination based on Carrier Sense (CS) is enabled, is the CS response time. The AGC module returns an estimate on the signal strength received at the antenna called RSSI (Received Signal Strength Indicator). CS is asserted when the RSSI is...
we fingerprinted each and every grid cell on the floor map and stored the Wi-Fi RSSI (Radio Signal Strength Indicator) strength range from all the concerned access points into a database. These values would help us in uniquely identifying the node as shown in Fig.2. In ...
Do you use some software or just a manual one .I would say try to use some real time softaware that give you RSSI and Link quality values so that we can align the antenna as per link quality parameters. Pinging with some bytes not always give's you correct quality of link that is e...
The radio signal strength indication (RSSI) is used to determine distance between two nodes, and triangulation is used to determine position. A localization process can be used to improve the position determination. In one embodiment, the mobile node periodically sends out packets containing RSSI and...
(conventionally available) RSSI of the reception is in a signal strength range that could trip the WB JD thresholds in the hysteresis pinch-off region. If not, normal mode switching is permitted at233. If at235the RSSI of the reception is in a signal strength range that could trip the WB...

Location tracking is used to determine the location of a device in a wireless network. Location tracking techniques include, for example, distance based techniques such as Time of Arrival (ToA), Time Difference of Arrival (TDoA), and Received Signal Strength Indication (RSSI), and angle based ...
相对于 RSSI, CSI 是更加细粒度(finer-grained)的测量。 2. 无线室内定位综述(WIRELESS INDOOR LOCALIZATION OVERVIEW) 无线室内定位方案可分为将(1)将无线信号测量结果映射为相对于参考点的距离和方向的几何参数(geometric parameters)或者(2)预设地标(prelabeled landmarks)即指纹算法。

1. 2.1 Localization and Path Planning We developed a reference coordinate system by dividing the entire floor plan into a grid. Subsequently, we fingerprinted each and every grid cell on the floor map and stored the Wi-Fi RSSI (Radio Signal Strength Indicator) strength range from all the ...
