3.
IrDA Control system uses 16PSM coding scheme over 1.5MHz sub-carrier. See IrDA Control Physical Layer Link
Specification for the details of coding scheme and pulse characteristics.
See Figure 5.1 (below) for the viewing angle definition.
An in-band optical signal is a pulse/sequence where the peak wavelength
λ
p, is defined as 850nm <
λ
p < 900nm,
and the pulse characteristics are compliant with the IrDA Control Physical Layer Link Specification.
