802.11n
VoWiFi Reference Design
Redpine’s
RS9110-N-11-41 is a complete IEEE 802.11bgn
VoWiFi phone reference design based
on its RS9110-N-11-02 - industry’s
leading ultra low power 802.11n module,
and SiTel Semiconductor's SC14450 system-
on-chip. The RS9110-N-11-02 is a complete
IEEE 802.11bgn device, which is designed
for mobile and handheld consumer applications,
and it comes with an integrated MAC,
baseband processor, RF transceiver and
power amplifier. The SC14450 is a fully
integrated DECT and VoIP device, featuring
a compact RISC microcontroller for general
processing, including power management
and MMI functionality, and it is supplemented
by two user-programmable Gen2DSPs for
voice CODECs and audio processing, enabling
color LCD Man Machine Interfaces (MMIs),
text-to-speech, voice enhancement, animated
JPEGs, Hi-Fi audio and advanced ring
tones.
The RS9110-N-11-41 uClinux based VoWiFi
reference design conforms to 802.11n
draft 2.0, and it supports advanced
power saving techniques including WMM-PS,
packet classification and voice prioritization
through 802.11e and WMM, advanced security
through standard based WEP 64/128, WPA,
and WPA2.
