It supports Windows Mobile, according to the company.
The company's earlier WLAN CSM, the
VWLAN7100, which does not include the SV1000 VoIP Engine, is pictured above.
The SV1000 VoIP Engine, which is included in the upcoming WLAN7101, has been optimized for efficient execution of VoIP functions such as advanced speech codecs, jitter buffering, encryption, and acoustic echo cancellation, according to SyChip. This results in reduced processor bandwidth and memory accesses, and, in turn, lower power consumption. SyChip claims that VoIP operations on the SV1000 typically require a third to a fifth of the power required on general purpose processors. The company estimates that the phones SV1000 draws around 14 mA during a VoIP call, and can support more than eight hours of talk time using a typical cell phone battery.

- G.711, G.729A/B, G.723, G.726 VoCoders
- SIP 2.0 stack
- jitter buffer
- call control functions
- IPSEC
- WMM Quality of Service (QoS)
- WPA2 security
- Bluetooth co-existence
"System cost and power efficiency are playing a large role in the growth of VoIP in handheld markets," said Will Strauss, president of Forward Concepts. "SyChip, by developing their own DSP-based VoIP engine, has taken true strides to deliver a solution that will enable mobile VoIP phones with competitive talk times and price points."
The VWLAN7101 (including the SV1000) will be available for OEM sampling early in the second quarter, according to SyChip. It will be packaged in a near Quad Flat No-Lead package (QFN) that allows for direct attachment to the main printed circuit board using standard surface-mount technology. The module will be priced at $15 in volumes of 100,000.
