Wireless Sensor Networks: Perceiving the World

Wireless Sensor Networks: Perceiving the World

Humans are now in the information age, and sensor technology, as the most important and fundamental technology for information acquisition, has also seen significant development. The development of sensor networks can be divided into three stages: sensors → wireless sensors → wireless sensor networks. The first stage can be traced back to the traditional sensor … Read more

Overview of BLE Rate Adaptive Algorithm Based on RSSI Threshold

Overview of BLE Rate Adaptive Algorithm Based on RSSI Threshold

Sun Zhongjie (Nanjing Silan Microelectronics Technology Co., Ltd.,Jiangsu Nanjing 210042) Abstract:In recent years,how to reasonably use multiple rates for communication in BLE has received wide attention, but most studies focus on performance optimization at a single communication rate, which has a certain impact on the throughput of BLE device systems。To address these issues, a RSSI … Read more

Understanding 5G Measurements: RSRP, RSSI, RSRQ, and SINR

Understanding 5G Measurements: RSRP, RSSI, RSRQ, and SINR

The terminal (UE) performs wireless measurements of CRS signal RSRP, RSRQ, and SNR for the serving cell in 4G (LTE). Since the 5G (NR) network uses SS (Synchronous) and CSI (Channel State Information) signals, 3GPP has redefined the measurements for the terminal (UE), which include RSRP, RSSI, RSRQ, and SINR. Where: For FR-1, the measurement … Read more
