LTE Overview

LTE designated as a fourth-generation (4G) mobile specification, LTE is designed to provide multi-megabit bandwidth, more efficient use of the radio network, latency reduction, and improved mobility. This combination aims to enhance the subscriber's interaction with the network and further drive the demand for mobile multimedia services. With wireless broadband, users can more readily access their Internet services, such as online television, blogging, social networking, and interactive gaming - all on the go.

Changes in mobile communications have always been evolutionary, and the deployment of LTE will be the same. It will be a transition from 3G to 4G over a period of several years, as is the case still with the transition from 2G to 3G. As a result, mobile operators must look for strategies and solutions that will enhance their existing 3G networks, while addressing their 4G deployment requirements without requiring a "forklift" upgrade.

Specifically, mobile operators need the multimedia core network to be readily upgradeable to meet the requirements of the System Architecture Evolution (SAE), the 4G core network architecture of the LTE standard.

Solutions already deployed in the market may include many of the elements required of the 4G network, including integrated intelligence, simplified network architecture, high bandwidth performance capabilities, and enhanced mobility. Only solutions capable of supporting multiple functions in a single node through a software upgrade will protect today's investment for tomorrow's network, and avoid a costly replacement of the existing systems.

Africa: 3G, 4G and the speed of evolution


     The article is about African operators to be the continent's first commercial 4G network using Long-Term Evolution (LTE) technology.it tells that it is getting longer than it should to approve licences for spectrums.  It also mentions interesting measures taken by companies to cut roll-out costs by using existing 2G and 3G base stations to accommodate 4G capabilities. Not much on the evolution of communication in this article, just pointing the lack of pace in implementing 4G technology by regulators.
