This document provides an overview of 4G wireless technology. It discusses the history and evolution from 1G to 4G networks. 4G is intended to complement and replace 3G systems by providing high-speed internet access and multimedia services over an all-IP network with data rates of at least 100 Mbps for high-mobility communication and 1 Gbps for stationary users. The document outlines key 4G features, standards, objectives, advantages and disadvantages.
Our ultimate goal is to communicate with any type of information with anyone, at anytime, from anywhere. This is possible with the aid of WIRELESS TECHNOLOGY.
4G refers to the fourth generation of cellular wireless standards. It is a successor to 3G and 2G technologies. 4G will be Convergence Platform providing clear advantages in terms of Coverage, Bandwidth, Power Consumption, variety Services ranging from Pop-Up advertisements to Location-Based services and IP Data casting ones.
PPT about 4G technology which I made for my college purpose.
PPT displays Evolution, Architecture, Working Procedure, Advantages and Disadvantages of 4T Technology.

5G is the short for fifth generation, a mobile broadband technology that is in the early stages of works and likely to be in place six to seven years from now.
A 5G network will be able to handle 10,000 times more call and data traffic than the current 3G or 4G network.
Data download speeds on 5G networks are likely to be several hundred times more than 4G.
5G mobile technology will change the means to use cell phones within very high bandwidth.

This is the slides for the 4G technology which will improve the basic knowledge of beginner and also useful for the engineering student on the basis for seminar. It's main benefit is the format which is standard one.
The 4G technology is nothing less than ground breaking. The advancements that have been made from 3G to 4G alone are mind blowing. With the data processing speed being increased to at least 100 Mbit/sec the possibilities are limitless in the wireless communication world. The 4G technology has a great present and future scope and worth. It makes the average person really think about what is possible with wireless communication? If there ever is a 5G network, how powerful will it be and what will it possibly be able to do that the 4G doesn’t already do?
TeliaSonera was the first operator in the world to commercially launch 4G. It was in late 2009, in the city centres of Stockholm and Oslo. 4G is the short term for fourth-generation wireless. It is still a research lab standard , the stage of broadband mobile communications that will supersede the third generation (3G). It is expected that end-to-end IP and high-quality streaming video will be among 4G's distinguishing features.
A 4G system will be able to provide a comprehensive IP solution where voice , data and streamed multimedia can be given to the users on “ Anytime Anywhere ” basis and higher data rates than the previous generations.
It will be a fully IP based integrated system capable of providing between 100 Mbps to 1 Gbps in both indoor and outdoor with premium quality and high security.
It is going to be launched in the year 2010.

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.
