Included in these links are Serial Infrared (SIR) supporting speeds up to Kbps, Medium Infrared (MIR) supporting Mbps and Mbps data rates, Fast Infrared (FIR) supporting a 4.0 Mbps data rate, and Very Fast Infrared (VFIR) supporting 14.0 Mbps.ġ4 In addition to the base standards, IrDA has specified several optional layers such as: Tiny TP (Tiny Transport Protocol) provide independently flow controlled transport connections segmentation and reassembly. IrLMP is multipoint-capable.ġ3 IrDA defined four kinds of infrared links to support different data rates. IrLAP (Infrared Link Access Protocol) is a protocol, based on the HDLC, designed to control an infrared link IrLMP (Infrared Link Management Protocol) is a multiplexing protocol designed to run on top of IrLAP.

These devices include cell phones, pagers, laptops, PDAs, digital cameras, handheld scanners, and laser printers.ġ0 The IrDA standard has both support and user applications in all major operating systems including all recent versions of Windows, Windows CE, Linux, as well as the Palm operating systemsġ2 IrDA has defined an interface for infrared communications that consists of base three layers: IrPHY (Infrared Physical Layer), is implemented by hardware vendors and defines four types of infrared hardware implementation.

IrDA-Control has its own set of mandatory protocols: PHY (Physical), MAC (Media Access Control), and LLC (Logical Link Control).Ĩ IrDA technology has emerged as one of the most promising wireless solutions because it offers several compelling advantages over other types of wireless communication interfaces Although infrared is only applicable between two devices at a time and cannot transmit through walls, the positive aspects of this technology are manyĩ Because infrared can only communicate from one device to another and because this communication must be line-of-sight, there is no risk that someone may intentionally or unintentionally obtain your information as it is being transferred IrDA infrared port module is the most mature of the wireless communications standards.

Two common types of IR technologies: TV Remote (TVR) and IrDA (Infrared Data Association) standard protocol.Ĥ IrDA standard -> wireless communication link between two devices in which the information is transmitted using infrared light A set of specifications for providing a universal twoway wireless infrared data communications, based on a practical cost, short-range point-to-point user model The standard defines the physical characteristics of the interface, the communications protocols that provide for different needs, and the transmission speeds at which the infrared device communicates.ĥ Two basics of the infrared communication standards are: IrDA-Data and IrDA-ControlĦ IrDA-Data IrDA-Data defines the standard for the wireless, two-way infrared data transmission between two devices and consists of a set of mandatory protocols: IrPHY (Physical), IrLAP (Link Access), and IrLMP (Link Management)ħ IrDA-Control Infrared standard that allows wireless peripherals such as keyboards, mouse, game pads, joysticks, and other pointing devices to interact with many types of host devices Host devices include PCs, home appliances, game consoles, and TV/ audio devices/ Web set top boxes Not the same as the standard TV Remote Control. 1 InfraRed(IR) Communication Prof Prabhat Ranjan DA-IICT, GandhinagarĢ Reference %20Automation/Communication-house/infraredcommunication.phpģ IR Standards The two most popular mediums in the wireless arena are Infrared (IR) and Radio Frequency (RF) IR technologies are better suited for short distance, low-to-medium data throughput, and wireless communication channels.
