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.

3ants(Engage, Enable, Enrich) - The Review

3ants(Engage, Enable, Enrich) , is a Personalized Multimedia Tool (PTM). This is the medium used to tag and share information on LTE(Long Term Evolution) technology for Mobile and Satellite Communications assignment. Through my experience experimenting on this tool I found out that it is a fairly moderate tool in terms of technical wise.
              At the beginning the PTM was still a confusing tool to use even though after being brief by Mr Simon. The process of registering inside the system consume a lot of time and we had to save page by page where I did the mistake of assuming the next button would save and go to the next level of the process. Besides that, the tagging and sharing also had some glitch at the beginning where I uploaded few article and videos in the PTM and it did show the tagging and sharing history for that particular day. When I logged in the next day my articles still exist but the history of it are gone. This prompted me to tag my own articles and videos again. The good news about this is the issue with tagging and sharing have been resolved recently.
              The PTM also always redirect to a different website that is powering it. This made the process of adding information consuming a lot of time. Furthermore, we need to update our profile every time we are logging in to the system made the system less efficient. Other than that the system was a good information exchange tool. There are still few glitches to amend once they are done this system will be a reliable system.
