Recent Advances in Wireless Localization Technologies

摘要

Most wireless devices manufactured today are equipped with a plurality of sensors and communication capabilities. Handheld devices can nowadays connect through multiple communication networks, such as 3G/LTE, WiFi, Bluetooth, Zigbee, WiMax, UWB, etc. They are also capable of sensing the environment, taking still images or videos, finding their location, detecting hand movements via accelerometers, and reading RFID tags. These devices have advanced operating systems capable of sophisticated signal processing and wireless communications. Much research is needed to use the sensing and communication capabilities of the newest generation of wireless devices to build new applications such as real-time youtube or wikis that collect, process, and report live data to public for security, news, or entertainment purposes. Among the applications envisioned for the new technology are vehicular networks, assistive technologies, eHoming (smart home), and the entertainment industry.
