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.

LTE opportunities and challenges for Telcos

       The article gave me better vision of LTE technology where it explain why there is the need for LTE technology because of the demand of the mobile data traffic increasing in recent years. Then it mentioned about the technology option for the operator to utilise for LTE which are Frequency Domain Division FDD and Time Domain Division TDD with the aid of tables. Besides that, it also mentioned about the challenges in deploying LTE and future steps for telco company have to endure.
