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...
1. 简介 由于多径衰落 (multipath fading) 和 时间动态(temporal dynamics) 的原因, RSSI在复杂环境中性能急剧下降。与 RSSI 不同,PHY 层的功率特征(power feature)即信道响应(channel response)能够区分多径特征,因此具有实现精确普适(pervasive)室内定位的潜力。从概念上讲,对RSSI来说信道响应类似于阳光下的彩虹,...
After some early struggles, I've found the Si4355 pretty easy to work with using the demo code. Except for RSSI - I can't get that to work despite many suggestions here. Can you confirm that the programming of the chip is successful? result = si4455_configuration_init(pRadioConfiguration...
CONFIG_BT_CTLR_CONN_RSSI=y CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=y # This seems to fix the following assertion: # ASSERTION FAIL [!radio_is_ready()] @ WEST_TOPDIR/zephyr/subsys/bluetooth/controller/ll_sw/nordic/lll/lll_conn.c:317 # See https://github.com/zephyrproject-rtos/zephyr/...

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 concerned access points into a database. ...
1.A method of wireless communication performed by a user equipment (UE), comprising:receiving a paging message from a base station associated with a first radio access network (RAN) while operating in an inactive or idle mode on the first RAN and while operating in a connected mode on a se...
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...
