Introduction of IrDAIntroduction of IrDA

• IrDA 裝置是使用紅外線的 LED. 其波長大多是介於 875 nm +- 30 nm 之間 .

• IrDA 裝置其距離約工作在 1.0m .

• 依傳輸速度可分為：• SIR115.2Kbps• MIR1.152Mbps• FIR4.0Mbps• VFIR16Mbps

Protocol StackProtocol Stack

IrPHY

IrPHYIrPHY

• 實體訊號層 (physical signal)

• 為實際的紅外線裝置，資料便是透過它來傳送

• 其發射頻率介於 33kHz-40kHz 之間• 其傳送資料封包是使用 CRC 的錯誤檢查碼格式

• 連結存取協定 (link access protocol)

• 用來提供和維護 IrDA 裝置間的可靠連結• IrLAP 提供兩種一般形式的服務

• Connectionless Services• Connection-oriented Services

IrLMPIrLMP

• 連結管理協定 (link management protocol)

• Provides multiplexing of the IrLAP layer

• Support for multiple application to operate

independently and concurrently

IR Remote ControlIR Remote Control

• Low cost solution of remote control

• No specific stack

• Control signal defined by manufactory
