Ausdauer, the stumbling block to high quality wireless IP telephony is not the window CE compatibility in regards to N2P. you may be right that it doesn't take long for a group of experienced window programmers to make N2P operable in window CE device. the problem with wireless IP telephony is the interface between the IP telephony providers (N2P, DeltaThree, etc.) and the wireless IP carriers/operators. standards must be set up for this phase. it is easy to transport data packets over IP, but it is very quality sensitive with voice packets. the end-to-end quality of service for wireline VoIP is greatly but only gradually improved with new equipment and fiber infratructure, yet the work will continue for many more years to achieve the near toll quality for VoIP. when wireless IP network is added to the picture quality would degrade because it is the weak link due to further delay and radio frequency related interferences (i am fortunate to understand this because i work in the wireless telecommunications industry). this wireless IP telephony will be developed and N2P will benefit in the near future, in my opinion. --------------------------------------------------------- Wireless IP telephony: Combining bandwidth and content DAN MacDONALD Like everyone else in the battle to become the single provider of communications services, wireless operators and Internet service providers are searching for cost-effective ways to differentiate themselves and grow their markets. Yet despite many unique advantages each offers the customer, both are limited in their ability to diversify their services and reach potential new customers. For example, wireless operators have extensive expertise in voice services, the ability to bypass the high cost of the wired local loop and experience in customer care and billing for real-time services. However, they need content to provide the complete package of communications services that customers are demanding. And without it, they are left to compete on price alone to differentiate themselves. On the other hand, ISPs offer Internet access, Web hosting and remote access services--the content customers want--but they don't have their own delivery infrastructure in place. Therefore, most of them must pay a local service provider--in many cases a competitor--to reach their customers. And while Internet protocol telephony technology now enables ISPs to complement their data offerings with reliable voice services, they don't have the expertise required to compete with existing voice providers. An IP-enabled wireless network would allow ISPs and wireless providers to combine their expertise, bandwidth and content to provide consolidated communications services, including Web access, e-mail, fax, local voice and long-distance. With access to the wireless infrastructure, ISPs' markets will no longer be limited to those supported by the wired infrastructure. The wireless network will enable them not only to forgo the high cost of routing transmissions over the local loop, but also to quickly deploy voice and high-speed bandwidth services in new markets. These markets include remote places not currently served by a wired infrastructure and places where it is not economically feasible to build or extend a fixed-line network. The delivery of IP telephony services over wireless networks is evolving in three phases. The first is long-distance service. In the second phase, carriers can offer virtual private networks that connect voice and data services for distinct offices within a city. Finally, ISPs and wireless operators will be able to provide IP Centrex services that will allow them to deliver IP telephony to the desktop. The first and second phases are available today. Phase three is not far off. Looking further ahead, we will soon turn to ISPs and wireless operators for telecommuting solutions, multimedia collaboration and videoconferencing, once again changing the way we think about telecom services.
