Introduction
• 4G usually refers to the successor of the 3G and 2G standards.
• 4G is a broader term and could include standards outside IMT-Advanced.
• A 4G system may upgrade existing communication networks and is expected to provide a secure IP based solution where facilities such as voice, data and streamed multimedia will be provided to users on an "Anytime, Anywhere" basis and at much higher data rates compared to previous generations.
What is 4G ?
4G, fourth-generation, is a technology that will transform wireless communications in a completely new way.
It is also known as “beyond 3G,"
It is also known as “beyond 3G," since it provides a secure IP (Internet Protocol) solution.
History of 4G
• At the end of the 1940’s, the first radio telephone service was introduced, and was designed to users in cars to the public land-line based telephone network.
• Then, in the sixties, a system launched by Bell Systems, called IMTS, or, “Improved Mobile Telephone Service", brought quite a few improvements such as direct dialling and more bandwidth.
