The typical sweet spot for IrDA communications is from 5 cm to 60 cm away from a transceiver, in the center of the cone.
IrDA data communications operate in half-duplex mode because while transmitting, a device’s receiver is blinded by the light of its own transmitter, and thus, full-duplex communication is not feasible.

 IrDA: Background and Overview   (Site not responding. Last check: )
IrDA is a protocol suite designed to support transmission of data between two devices over short-range point-to-point infrared at speeds between 9.6 kilobits per second (Kb/s) and 4Mb/s.
This is especially confusing when the SIR IrDA hardware itself may need to be configured on a real serial port, and then the customer must further configure their application to use a virtual serial port.
No other IrDA application or driver will be able to run on that system, even though the underlying IrDA protocols provide support allowing multiple applications to wait for incoming connections and clients to select a target application at connect time through established protocol mechanisms.

However, there was a time not long ago, when the only way to wirelessly connect two devices, was via infrared (aka IrDA).
While IrDA isn't dead by any means, we just don't seem to think of it that often.
I would think that not having USB 2.0 would rate as a con or is it that the speed of the IrDa itself is the limiting factor and having a faster would not improve the overall speed at all?

With the simple implementation of the infrared connection it is enough to know the following: each IrDA server application that maintains the infrared connection, enables such an LSAP selector and a service name (as in our example); each Client application uses this kind of the addressing to build up a connection to the server application.

 IrDA with the BASIC Stamp and MAX3100
The IrDA specification for low speed (115 kbaud and under!) communications allows the length of the transmitted pulse to be much shorter than 3/16 of the bit period.
The IrDA receive circuitry must be able to detect the short pulses of light and "stretch" them to fill the standard bit width at the current baud rate for input to standard RS232 serial ports.
A third and probably the best alternative for the longest distance of operation is one of the dedicated IrDA modules, that have an IR LED with a driver circuit and also a PIN photodiode with a high gain high speed amplifier all integrated onto one chip.

 Bluetooth™ and Other Wireless Technologies > IrDA and Bluetooth Wireless Communication Compared
IrDA is a specific use of infrared light as a communications medium; Bluetooth technology is a specific use of radio waves as a communications medium.
IrDA range is about 1 meter and, as noted already, generally requires a line of sight to establish a connection.
IrDA hardware also already is less expensive than Bluetooth radio modules, owing largely to the maturity and wide deployment of IrDA.

IrDA publishes reference documents covering various aspects ranging from the physical aspects of the infrared beam, wavelength, power, beam angle etc, to definitions of the layered protocol structure required to perform its software functions.
IrDA is not the same, and has nothing to do with the infrared systems used in TV or video recorder remote controls now in common use.
Remember that IrDA is essentially a half duplex protocol, and the host must be constrained from sending data when the channel is not ready to receive it.

 Linux.com - Beyond IrDA
If it is desired to communicate with a standard IrDA device that may have minimum transmitter intensity, the receiver intensity must be increased.
Basic physics has the inverse square law: the intensity drops with the SQUARE of the distance, so going from 1 to 5 meters requires 25x the power (and battery drain on a portable device), or 25x the sensitivity (and dynamic range - it still has to be able to work at 3 inches).
IrDA is still unbeatable in price/performance and with the new additions to the standards family like AIR and VFIR, it's really good to see that IrDA is moving in the right direction."

 Networking over IrDA in Windows XP   (Site not responding. Last check: )
Although the IrDA protocol implementation in Windows 2000 was stable and the architecture was clean, this implementation lacked the broad legacy application support provided in Windows 98 and Windows Millennium Edition (Windows Me).
The IrDA stack in Windows 98/Me supported networking profiles strictly over the IrCOMM kernel-mode driver, to serve as a straightforward cable replacement; however, the IrDA stack in Windows 2000 provided no support for IrCOMM and based its networking on newly-designed IrNET and IrDial protocols.
