What are the practical aspects of LTE, LTE-Advanced Pro and 5G? – A new book.

This book guides you through the LTE, LTE-Advanced Pro and 5G from the perspective of practical aspects of air interface, RAN, Core Network and end-to-end data transfer. The practical approach is reflected by the angle of system design, link budget process, network planning, parameter configurations and optimizations together with the required tradeoffs. We also evaluate the different features’ impact on the overall system as it evolves from LTE to LTE-Advanced and then going further to LTE-Advanced Pro and 5G.

Having billions of IP addresses divided into many different subnets, without routing there would be muddle that will prevent the whole Internet from working. So, routing is like the set of rules that allows localize particular IP network and IP addresses that belongs to that network.
