ASTRI

Wi-Fi is the dominant wireless data access technology at home, at work and in public areas. In the latter case, there has been an on-going massive growth in worldwide Wi-Fi hot spot deployment, either by municipalities or by commercial providers. A handset that can be used at home, in the office, and at an ever-growing number of hot spots is a very attractive proposition to end users.

ASTRI's R&D in Voice over WLAN (VoWLAN) has already offered a robust and feature-rich Wi-Fi phone solution, W-iSIP, for the home and enterprise market segments. To take advantage of the growth of public Wi-Fi coverage, ASTRI has expanded this solution into the wireless service provider segment.

Boingo Wireless Inc. is the leading aggregator of Wi-Fi network operators, with over 60,000 hot spots worldwide and comprehensive roaming support for mobile devices. This roaming support – in the form of the Boingo Wi-Fi Embedded Toolkit – enables ASTRI to seamlessly integrate public hot spot identification and authentication into the mobile device user experience.

The hot-spot-enabled W-iSIP has addressed the well-known challenges of hot spot authentication, session persistence, and inter-hot spot session management, all under the resource constraints of a battery-powered embedded system. It is the perfect platform to facilitate this win-win partnership between a handset vendor and Boingo Wireless.

W-iSIP, based on the standard Voice over IP protocol SIP, enables rapid entry into the Wi-Fi handset market, a market already recognized by brand-name vendors. Knowing that time-to-market is very critical, the W-iSIP reference design and software toolkit offer ODM/OEM a cost-effective way to produce a handset with vendor-specific user experience and phone features.
