  2. What is RFID?

  3. RFID stands for radio frequency identification. It is one of automated systems which used to collect data • The beginning of innovating RFID is when scientists started to study radio waves specifications in the 1940s

  4. -RFID systems -Sensors network -Architectures and Network Programming - RFID Systems and In-network Processing

  5. Usage • RFID been used in multiple applications most popular are: • In hospital Patient/ medical equipment tracking • In marketing and supply chain replacing the barcode. • In security monitoring and tracking devices GPS • In computer and wireless network as in the antenna

  6. RFID System:

  7. Frequencies • low frequency (blow 1 MHZ), universal frequency required worldwide for scientific instrumentation • 13.56 MHZ • and ultra high frequency which is over 800 MHZ

  8. The Transmission Differences • Omnidirectional Antennas: • which radiate signal could be more or less in all directions. • These are used when the relative position of the other station is unknown or random. • also used at lower frequencies where a directional antenna would be too large, or basically to cut costs in applications where no need for a directional antenna .

  9. Directional or Laser-beam Antennas: • which are intended to specially radiate on a precise focus direction or directional shape. • With directional antenna we can expect an effective beam width • however! The beam width decreases as distance increases

  10. The Integration of RFID & Wireless Network sensors

  11. The RFID or Radio Frequency Identification, has been recognized as a key element to the Network, globally. • As the information can be accessed at any time any where via the network. although its a fantastic innovation it dose have its drawback • Privacy Issue is the main concern, as the technology have the capability to pinpoint the locations a privacy will always be a an issue

  12. Thank you. Any question or comment?
