Cisco Systems is apparently working with Intel, Nokia and Research In Motion to improve the performance of VoIP-over-wireless networks.
Nokia plans to build new voice-ready features into wireless devices such as dual-mode cellular/Wi-Fi phones, RIM is looking at ways to push the technology into its BlackBerry devices and Intel plans to build the new technology into its mobile chipsets.
The three vendors are among the first to use the newest version of Cisco Compatible Extensions (CCX), a toolset that Cisco offers to device vendors to ensure compatibility with its WLAN infrastructure. The latest version of CCX, which launched last month and also is available to other vendors, includes new features that Cisco says should be built into client devices to optimize the performance of VoWLANs by improving communications between clients and access points.
