It can be predicted, based on software radio for mobile communications will have the following characteristics: the same hardware platform is not compatible with the system; with automatic roaming capabilities, able to intelligently switch between different systems; can download the utility software and to upgrade its own; support voice, data, images and faxes, and other business, and according to the wireless industry is the coexistence of multiple standards bureau network, the work of different standards in different frequency bands, for the same modulation, resulting in interoperability between systems is difficult. WLAN mobility is poor, and software radio is one of the most promising technologies to address these issues. Development of software radio is a fully programmable hardware platforms, all applications software on the platform through the programming. In other words, different systems of base stations and mobile terminals are built on the same hardware can be based on different software. The technology will be able to ensure a variety of mobile units, seamless integration between mobile devices and greatly reduce the construction costs.
As the recruits this market, Microsoft is not only facing competition from the traditional information industry, more from the phone, the three telecom operators in the resistance. As the telecommunications and computer communications boundaries become blurred, many companies have begun to rethink the way of communications and IT architecture. E-mail and telephone number of enterprises are managed by different departments, but also makes the IT department can not have complete jurisdiction. Most people think that with the dominance in the IT companies, Microsoft has a big advantage, but the Exchange director Dave Thompson said he played a lot of dealings with the company, he found that technical staff is not necessarily more open attitude. "Management of the phone were often prefer to be able to manage voice communications infrastructure," he said in an interview. However, Exchange does not just want the new version to replace the traditional telephone only. In fact, it is one of the new features so that employees can call back to the company see the new mail and calendar. What employees can say they are looking, and Microsofts voice recognition software to interpret instructions, and then by speech synthesis software, the contents of the letter, "said" to him.
