IrPhy l.3 extended the Low Power Option to MIR and FIR and VFIR was added with lrPhy 1 .4.A new version of the standard in any case obsoletes the former version. With introducing the updated versions the old versions are obso- lete. Therefore the only valid lrDA standard is the actual version lrPhy l.4 (in Oct. 2002).
