Roadmap for Wireless Networks

It takes too long to lay and then re-lay wires. Wireless networks free devices and put people in motion. All wireless networks have one thing in common. They use electromagnetic spectrum. They connect radio devices in order to exchange content best exploited in mobile situations. Wireless networks are ultimately distinguished by the class of wireless device and type of application they serve, as shown in Table 1. Wireless networks connect six device classes: web phones, handhelds, pagers, voice portals, communicating appliances, and the web PC. Wireless networks deploy four families of wireless applications: messaging, web browsing, interactive, and conversational purposes. Keeping the technology of devices, networks, and applications in mind will help you give your mobile audiences new purpose with the wireless application and architecture you build.
