Aug 30, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive — views

TapRoot Systems is demonstrating its telephony middleware for Linux/Qtopia-based mobile phones at the Linux Mobile Communications Conference this week in Beijing. The company says its TapRoot telephony middleware provides a “comprehensive” set of APIs (application programming interfaces) for communication with 2G-3G networks.

The Beijing conference was organized by the China Academy of Telecommunications Research (CATR), and co-hosted by the Chinese Ministry of Information Industry (MII) and Trolltech, a TapRoot partner specializing in application frameworks for Linux-based phones and mobile devices. Other event sponsors included Wind River, MontaVista software, Sun Microsystems, Arphic, Flander, Freescale, Fujitsu BSC, Jataayu, Staikos Computing Services, Sophia Systems, STMicroelectronics, UDTech, VirtualLogix, and WSI.

TapRoot offers telephony interface products for all major smartphone OSes, including Microsoft Windows Mobile, Symbian, and Linux. It says its telephony middleware abstracts hardware and telephony services, to increase phone developer productivity. Its LinuxTel middleware supports Trolltech's Qtopia Greensuite initiative, it said.

Rick Phung, TapRoot's director of product management, stated, “Development of Linux mobile phones is on the rise and is changing the landscape of the mobile phone industry. Our LinuxTel telephony software is a critical piece.”

Mr. Zhang Xinsheng, deputy director of science and technology at the MII, added, “Due to its open-source characteristics and exemplary technological achievements, Linux continues to develop rapidly and present new opportunities. Mobile Linux will spur the development of China's mobile communications industry.”

In addition to telephony middleware, TapRoot sells mobile phone reference designs, and WLAN/WiMAX stacks for all popular smartphone OSes. A whitepaper on cellular modem abstraction interfaces writte by TapRoot co-founder Blane E. Rockafellow can be found here.
