Design and Implementation of Indoor Positioning System using Bluetooth Low Energy

Most of the positioning systems nowadays require GPS. In indoor environments, however, GPS signals cannot be received properly due to the obstructions of the walls in the building. Therefore, other techniques such as RFID, Zigbee, WIFI or Bluetooth, are used based on the power loss, cost, or transmission range considerations. Our study, conducted at the AI+ Experience Center of Chung Hua University, adopts Bluetooth 5.0-based equipment and uses the received signal strength indication (RSSI) and triangulation method to perform indoor positioning. Our results show that Bluetooth positioning is more accurate in the sense that when the distance is within 1∼3 meters, the error with the actual position is about 1 meter, which is more accurate than the RFID or WIFI positioning with the error of 2∼3 meters.

Design and Implementation of Indoor Positioning System Based on Bluetooth in Computer Room

In recent years, college public opinion has gradually become a hot spot of social concern. However, there are still many problems in colleges and universities in dealing with public opinion. It is of great significance to actively explore the characteristics and laws of public opinion communication in colleges and universities. In the perspective of social network analysis, this paper compares and analyzes two types of college public opinion communication networks: positive and negative. Finally summed up the internal law of public opinion communication in colleges and universities. It provides a new theoretical perspective for the study of college public opinion in the perspective of social network analysis, and can effectively improve the efficiency of colleges and universities in dealing with online public opinion.
