Introduction to RF DC
Automatic RF DC is Radio Frequency Data capture which is Auto Matic data capture using RF technology or network i.e. either Spread Spectrum or Narrow Band frequency, wherein the data capture is done on real time and online data transfer system takes place. It has a wireless terminal and a base receiving station, depending upon the application and the connectivity required.

What is Spread Spectrum?
A frequency which works on 2.4 GHZ or 2.5 GHZ, with limited coverage not meant for long area coverage. Explaining it further, it is a wireless communication method that spreads transmissions across a spectrum instead of transmitting over a fixed radio frequency.

What's a Narrow Band?
A frequency, which works on 433 MHz with long coverage, meant for transmitting data over a radio frequency, widely used in foreign countries for Supply Chain Management and Logistics.
