Seamless Communication Convergence Solution Running on Microsoft Windows Mobile

26th October , 2005

US : Sleipner S.A., a Milan based, wholly owned subsidiary company of Calypso Wireless, announced that Microsoft has invited Sleipner SA to demonstrate the Sleipner - Calypso CoMob ASNAP(TM) seamless mobility software solution at the Microsoft new technology area for Mobile Communications at the Microsoft SMAU 2005 trade show in Milan Italy.

It demonstrated the Sleipner CoMob Calypso's ASNAP(TM) patented technology, seamless mobility software for Mobile Phones and PDA software running on the Calypso C1250i dual mode WiFi-GPRS-GSM VoIP mobile phones. The Calypso's C1250i mobile phone which runs on Intel (NASDAQ: INTC) PXA series application processor and Microsoft (NASDAQ: MSFT) WinCE 5.0 operating system, has already been successfully demonstrated in field trials and has been demonstrated at the Microsoft booth in SMAU Milan, Italy.

Calypso' ASNAP(TM) patented technology for which it was granted U.S. Patent #6,680,923 titled "Communication system and method" (http://www.uspto.gov search U.S. patent number 6,680,923), which covers the seamless roaming of voice, video and data between Wide Area Network access points, such as cellular towers (GSM/GPRS/EDGE, CDMA, WCMDA etc.) and short-range Internet access points (such as Wi-Fi, Bluetooth, etc.) is the solution to deliver seamless connectivity to mobile phones, PDA and mobile devices.

"We're very happy to have Sleipner SA at our Microsoft Mobile Communication booth at SMAU 2005 in Milan, Italy, demonstrating the Sleipner Calypso CoMob ASNAP(TM) seamless mobility software for Mobile Phones and PDA software running on the Calypso C1250i WiFi-GPRS-GSM VoIP mobile phones," declared Fabio Falzea, Mobility Business Group Director for Microsoft Italy.

"We believe in the strong opportunities that WiFi broadband high speed connection will provide to mobile subscribers with many new services such as mobile real time video conferencing, document sharing and synchronization and other value added services. Convergence between cellular and WiFi coverage will represent a very interesting growth opportunity for the whole mobility business in the following years," further adds Falzea.

"CoMob is the first seamless mobility solution allowing mobile users to manage a cellular call (GSM/UMTS) and VoIP/WiFi calls with one single interface. CoMob products turn a Windows Mobile dual-mode Smart phone (with a WiFi and GSM/UMTS connection) into a telephone capable of receiving and making VoIP calls in the WiFi network-covered areas. In an office or in a house it behaves like a cordless telephone (an extension or a private telephone number) and it can an office or handle GSM calls in areas where a wireless WiFi connection is not available. When both connections are available, CoMob allows managing the two types of calls with hold and unhold functions," says Bruno Motta, Vice President of Marketing of Sleipner SA.

CoMob PDA features a point and click interface and is fully integrated with Pocket Outlook contacts while the phone version uses the Smart phone keyboard.

"The integration of CoMob products with Calypso's ASNAP(TM) patented technology will upgrade the coMob solutions to seamless switching, enabling a new paradigm in mobile communication and seamless switching: real seamless handling of communication," further adds Bruno Motta.

CoMob's parameter configuration takes place through an integrated web server which can also manage the complete dial plan and the call priorities and giving the users web based SMS messages remote control on the phone. coMob has been fully developed by Sleipner and is SIP protocol compliant (RFC 3261). It is based on proprietary middleware.

"We are delighted to demonstrate the Sleipner CoMob & Calypso's ASNAP(TM) seamless mobility software for Mobile Phones and PDA software running on the Calypso C1250i dual mode WiFi-GPRS-GSM VoIP mobile phones at the Microsoft new technology area for Mobile Communications. We are very excited about forging ahead with selling our products in Europe and the United States," says Mr. Michael Pizzi, Calypso Executive Vice President & General Counsel.
