What is RFID?

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

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

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 Usage

RFID System:

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

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. The Transmission Differences

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

The Integration of RFID & Wireless Network sensors

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

Thank you. Any question or comment?
