4G Communication Systems Emin Sharifov Introduction 4G, also known as Beyond 3G, is a term used to describe the next step in wireless communications Provides comprehensive
IP solution where voice, data and streamed multimedia can be given to users on an "Anytime, Anywhere" basis 4G will be a fully IP based integrated system Evolution of Communications Networks
First Generation: An analog system where voice was considered to be the main traffic Second Generation: All standards in this form are digital in form(GSM, IDEN) 3G: The systems in this standard are essentially a linear enhancement of 2G systems 2.75 G; 3G; 3.5G; 3G post 4G: the infrastructure and the terminals of 4G will have almost all the standards from 2G to 4G implemented
Objectives High network capacity: more simultaneous users per cell A data rate of at least 100 Mbit/s between any two points in the world Seamless connectivity and global roaming across multiple networks High quality of service for next generation multimedia support
USERS OF 4G The Japanese company NTT DoCoMo has been testing a 4G communication system prototype and is planning to release the first commercial network in 2010 Digiweb, an Irish wireless broadband company recently started to use it Verizon Wireless and Vodafone are getting together to establish 4g networks soon.
Sprint also announced that it is going to launch it in 2008 Any questions?? http://youtube.com/watch?v=bSWm5zvsJOc& feature=related
Copy Constructor. A copy constructor is a constructor with exactly one argument, and the data type of the argument is the same as the constructor's class. Need to make sure that the object and its copy are independent from each...

Our Purpose. Project Status. Prototype and Demo. Lessons learned so far. Planned changes for next term. Upcoming plans. To augment current collaboration tools by collecting and modeling historical project data to alert project stakeholders when signs of trouble are detected.
Any conservative force acting on an object within a system equals the negative derivative of the potential energy of the system with respect to x. Non-conservative forces: A force is non-conservative if it causes a change in mechanical energy; mechanical...
