Roger

technology

Roger

is a patended technology developed by Phonak,

which features adaptive, wireless transmission and runs

on the 2.4 GHz band. Roger

audio signals are digitized

and packaged into very short digital bursts of codes

packets and broadcast several times, each time using

different channels between 2.4000 and 2.4835 GHz.

Frequency-hopping between channels, in combination

with these repeated broadcasts, avoids interference

issues and ensures successful transmission.

Phonak has developed the proprietary Roger

microchip

for dedicated use with miniaturized ear-level receivers.

AES encryption The transmission is secured with an AES 128-bits

encryption where the code is exchanged at the time of

on demand synchronization. The robust Advanced

Encryption Standard (AES) is the algorithm trusted as

the standard by the U.S. Government and numerous

organizations.
