INFRARED DATA ASSOCIATION (IrDA)

1. INTRODUCTION

Infrared Data Association (IrDA) founded on 1993. IrDA is utilized for high speed short range, line of sight, point-to-point cordless data transfer via infrared light waves. IrDA is the radio transmission of light ray infrared measured in Terahertz or Trillions of Hertz (cycles per seconds) is modulated with information send from

In practice, there are some devices on market do not reach devices may reach up to several meter. The normal spot for IrDA communications is from 5cm to 60cm away from transceiver

Who use it ?
• Professionals scan business card from PDA to cell phone.
• Children wirelessly exchange games during break time
• Shoppers make purchases at grocery by pointing the handheld to the bar code items.
• Use on remote TV to change channel, turn on & off TV
• Teenager to share image or music.
• Cashier and buyers to scan bar code item.
• Business to transmitted document using fax
• Buyer paid using credit card.

3. DATA COMMUNICATION CONCEPTS

• Bandwidth
-the maximum projected bandwidth is 16 megabits per second.

• Security
-IrDA technology is a secure. Data being transmitted via infrared it’s very difficult to intercept or hack because it directional sent to who people you want. Data is safe because it cannot through wall or objects. Besides that data only can transmitted in short range.

4. THE TECHNOLOGY CAPABILITIES
• Error rate: Infrared radio frequencies can’t pass through the walls, this technologies cannot be used at obstacle place. Should be used in same room and maintain line of sight. The transmitter of one infrared enable device visible to receiver of another infrared enable device.
• Availability: use for longer interconnection and possibility for
