Two of the hottest technology areas today are "Web services" and "wirelesscomputing". Web services are software systems designed to supportinteroperable machine-to-machine interaction over a network. This interoperability is gained through a set of XML-based open standards, such as WSDL, SOAP, and UDDI. These standards provide a common approach for defining, publishing, and using web services. Web services are the preferred way to realize the Service-Oriented Architecture (SOA), which can help organizations streamline processes so that they can do business more efficiently, and adapt to changing needs and competition, enabling the software as a service concept.

Web services are inherently network-dependent, and therefore adapting them in a wireless environment poses several challenges due to the unreliable connectivity and low bandwidth imposed by wireless networks. And, the very mobility of devices increases the risk that a connection will be lost or degraded.

In this talk I will examine the trends and key technical issues in wireless web services. I will discuss the opportunities, challenges, and possible solutions in building and deploying wireless mobile web services.
