Will 3G really be the next big wireless technology

It appears that wireless technology has reached a turning point, as vendors and researchers prepare to take it to the next level. Most industry observers agree that next-level wireless technology will offer more bandwidth, security, and reliability, making it more suitable for multimedia, e-commerce, videoconferencing, and other advanced applications. A key issue for wireless is what form the technology's next generation will take. Many vendors, and other industry observers contend the next level will be the much-discussed third-generation wireless approach, which is actually a set of digital, packet-based, broadband technologies. Vendors are just starting to implement 3G, but some experts in the field are already questioning its functionality and usefulness.
