RFID Frequencies and Why There are So Many of Them
(Presented: April 21, 2004) |
|
|
| This presentation covers: |
|
|
|
|
* Overview of radio frequencies
* Relevance to RFID * Competitive frequencies: 13.56 Mhz, 900 Mhz, and 125 KHz
* Pros and cons of alternate frequencies
Speaker: Scott Balzer
Scott Balzer is an electronic design engineer with 18 plus years of design experience.
At NASA’s Jet Propulsion Laboratory in a Radar Research and Development group, Scott provided digital, analog and high level RF design on three different projects:
SIR-C
NSCAT
Cassini
At Precision Dynamics Corporation, Scott led the RFID development group. He designed an RFID wristband for hospital, outdoor events and jail inmate identification. He also provided custom gate antenna design for RFID readers, allowing the RFID wristband to be read while people are entering or exiting through a doorway.
At Escort Memory Systems as R&D Engineering Manager, he designed industrial tags and readers for RFID manufacturing automation. He led the development of an HF reader that reads RFID tags 8 feet across using a gate antenna system. The, then, state-of-the-art HF reader was about 4 feet. This accomplishment was made possible by developing a completely new and innovative antenna system and improved DSP RF algorithms. |
