SyChip recently introduced the VWLAN7100 Voice-over-Internet Protocol (VoIP) CSM, a part of its SyVoice family of products for smart phones, feature phones,  and PDA Phones. The VWLAN7100 CSM is a complete end-to-end Voice over Wireless LAN solution that can be quickly integrated into mobile phones to support the emerging dual-mode cellular and local area networks.

"SyVoice is our family of highly integrated and programmable modules that is targeted to the VoIP market.We are excited to release this product as the convergence of cellular and WLAN is rapidly taking hold in the wireless market space" said Moses Asom, co-founder and senior vice president of marketing and business development at SyChip. "We have one of the first products that is specifically targeted to the dual-mode
cellular phone market".
The VWLAN7100 CSM offers plug-n-play solution and includes all the hardware and software necessary to add VoIP and data functions to a standard cell phone. The module allows a mobile phone to roam between a cellular network and a WLAN network, giving the user the flexibility to maintain the most
cost effective voice connection. The module also allows a high-data-rate data connection over a WLAN network for standard data functions like Web browsing and email access.
"Market interest for dual-mode phones combining cellular and Mobile VoIP technology has seen an upward growth this year and will explode with adoption over the next few years," said J. Gerry Purdy, Ph.D., principal analyst of MobileTrax. "SyChip's SyVoice product offers an elegant combination of voice and Wi-
Fi in a single module. The implementation of multiple filtering technologies and a VoIP engine deliver a solution that addresses both quality of voice and service, as well as an efficient use of battery power." Long battery life is a critical requirement for mobile phone manufacturers.

The SyVoice VoIP engine is optimized to reduce power dissipation by offloading all the functions necessary to maintain a VoIP call from the host processor. The VoIP engine allows phones to have talk times of five plus hours and standby times of 100+ hours.
VWLAN7100 combines a VoIP processor and an 802.11b/802.11g WLAN modem. The module is designed to easily interface with most baseband and application processors on the market. The module also incorporates software features such as a SIP 2.0 stack; VoCoders G.711,  G.723, G.726, G.729AB, jitter buffer; call
control functions including origination/termination, forwarding, hold, waiting, transfer and 3-way; audio control; and IPSEC. SyChip will provide the driver to support operating systems such as Rex®, Windows Mobile®, Linux®, Symbian® and  Nucleus® Operating Systems.
The WLAN section of the CSM supports features including WMM, Quality of Service (QoS) traffic prioritization critical for VoIP and multimedia applications, WPA2 (IEEE802.11i) security and Bluetooth co-existence.
