EFR encoding decoder
function
The J6
（
GSM/DCS
）
is equipped with the
latest encoding decoder and audio
frequency technology, to achieve superior
audio quality.
At present, there are 3 types of encoding
decoder compatible with GSM/DCS:
yEnhance full rate （EFR）
yFull rate （FR）
yHalf rate （HR）
The J6 (GSM/DCS) mobile phone supports
the normally-used EFR and FR encoding
decoder.
All GSM and DCS cellular networks and
phones support FR encoding decoder.
If supported by the network operator, the
network operator will automatically select
the relevant encoding decoder, which will
be either EFR or FR.
The J6 model is programmed to
automatically select the EFR where this is
supported by the network, allowing you to
enjoy the superior audio quality provided by
EFR. Otherwise the phone will select FR.
At present, only some networks support
both the FR and EFR encoding decoder.
If the network operator cannot support EFR,
the J6 (GSM/DCS) mobile phone will
automatically adopt the FR encoding
decoder.
