The challenge of implementation of long term evolution / system architecture evolution (LTE/SAE)

Current 3GPP Release-8 is addressing Evolved-UTRAN or LTE as a new access network and SAE / EPC as an improved version of 3,5G core based on All-IP infrastructure. This paper describes the objectives of the actual LTE / SAE standard related to its deployment in Bosnia and Herzegovina and suggests how to implement it smoothly in a mid-size network.
