Portable Radios Integrated with RFID Function

Portable radios integrated with RFID function


As two way radios become more and more popular, the tractability of them grows more and more important. RFID can perfectly solve this problem and make radio communications most efficient and controllable.

What is a RFID


Radio Frequency Identification (RFID) is the technology to use radio waves to read and capture information stored on a tag attached to an object.  A RFID system is made up of two parts: a tag or label and a reader.



How does a RFID system work?


RFID tags or labels are embedded with a transmitter and a receiver. The RFID component on the tags has two parts: a microchip that stores and processes information, and an antenna to receive and transmit a signal. The tag contains the specific serial number for one specific object.

To read the information encoded on a tag, a two-way radio emits a signal to the tag using an antenna. The tag responds with the information written in its memory bank. The radio will then transmit the read results to an RFID computer program.

There are two types of RFID tags: passive and battery powered.  A passive RFID tag will use the radio wave energy to relay its stored information back to the RFID computer program.  A battery powered RFID tag is embedded with a small battery that powers the relay of information.



RFID Advantages


A significant advantage of RFID devices over other tracking devices is that the RFID device does not need to be positioned precisely relative to the scanner. We're all familiar with the difficulty that store checkout clerks sometimes have in making sure that a barcode can be read. And obviously, credit cards and ATM cards must be swiped through a special reader.

In contrast, RFID devices will work within a few feet (up to 20 feet for high-frequency devices) of the scanner. For example, you could just put all of your groceries or purchases in a bag, and set the bag on the scanner. It would be able to query all of the RFID devices and total your purchase immediately.

RFID technology has been available for more than fifty years. It has only been recently that the ability to manufacture the RFID devices has fallen to the point where they can be used as a "throwaway" inventory or control device. Alien Technologies recently sold 500 million RFID tags to Gillette at a cost of about ten cents per tag.

One reason that it has taken so long for RFID to come into common use is the lack of standards in the industry. Most companies invested in RFID technology only use the tags to track items within their control; many of the benefits of RFID come when items are tracked from company to company or from country to country.
