Near-Field Wireless Technology – Video Available

Near-field wireless technology is an emerging area of great importance in Radio Frequency Identification (RFID). Specific applications include low frequency (LF) and high frequency (HF) RFID, Near-Field Communications (NFC), Near-Field Electromagnetic Ranging (NFER), and wireless power transfer. This talk discusses the origins of near-field wireless, surveys applications, presents near-field links laws, and reviews the properties and performance of electrically-small antennas. This March 31, 2014 presentation to the Huntsville, AL section of the IEEE previews the full three hour workshop presented April 8, 2014 at the 8th Annual IEEE International Conference on RFID held in conjunction with 2014 RFID Journal Live.

 A couple of misstatements I caught in reviewing this: first, Preece transmitted near field wireless signals across the Bristol Channel not the “British” Channel; and second, “unlike” links go as 40dB/decade, not 20dB/decade in the near-field. Prezi slides are available here: http://bit.ly/1x0FY7W if you’d like to take a closer look. In some of the views, you can’t see all the details.
