With the introduction of 4G systems, wireless networks are evolving to next-generation packet architectures capable of supporting enhanced broadband connections. Simple text messaging and slow email downloads are being replaced by high-speed connections that support true mobile office applications, real time video, streaming music, and other rich multimedia applications. 4G wireless networks will approach the broadband speeds and user experience now provided by traditional DSL and cable modem wireline service. From the wireless operator's perspective, 4G systems are vastly more efficient at using valuable wireless spectrum. These spectral efficiency improvements support new high-speed services, as well as larger numbers of users.
