The two devices that communicate simulate full duplex communication by quickly turning the link around. 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. The typical sweet spot for IrDA communications is from 5 to 60 cm (2.0 to 24 in) away from a transceiver, in the center of the cone. There are also devices that do not tolerate extreme closeness. In practice, there are some devices on the market that do not reach one meter, while other devices may reach up to several meters. Similarly, the specifications require that a maximum irradiance not be exceeded so that a receiver is not overwhelmed with brightness when a device comes close. The IrDA physical specifications require that a minimum irradiance be maintained so that a signal is visible up to a meter away. IrDA transceivers communicate with infrared pulses (samples) in a cone that extends minimum 15 degrees half angle off center. Combined with a low bit error rate of generally <10E-9, that communication could be very efficient compared to other wireless solutions. Finally data blocks up to 8 MByte can be sent at once. This can be adjusted with a parameter called Window Size (1-127). Additionally bigger blocks of data can be transferred by sending multiple frames consecutively. The frame size depends on the data rate mostly and varies between 64 Byte and 64 kByte. Range: standard: 1 m low power to low power: 0.2 m standard to low power: 0.3 m, The 10 GigaIR also define new usage models that supports higher link distances up to several meters.5/10GigaIR: seems to be a new IrPHY coming soon.Different data rates uses different modulation/coding schemes: It comprises optical link definitions, modulation, coding, cyclic redundancy check (CRC) and the framer.
