Ensuring telecommunication network security through cryptology: a case of 4G and 5G LTE cellular network providers

4G LTE Cellular Technology: Network Architecture and Mobile Standards

he earlier evolution of broadband wireless technologies is the consequence of growing demand in the world for best ever mobile Internet access and wireless multimedia applications. This paper explores the network architecture of 4G (4th Generation) and LTE (Long Term Evolution) wireless technologies, the mobile standards used by these technologies and key features. The 4G architecture basically...

4G Network Migration cdma2000TM to LTE Evolution

A Modified Empirical Path Loss Model for 4G LTE Network in Lagos, Nigeria

The quality of signal at a particular location is essential to determine the performance of mobile system. The problem of poor network in Lagos, Nigeria needs to be addressed especially now that the attention is toward online learning and meetings. Existing empirical Path Loss (PL) models designed elsewhere are not appropriate for predicting the 4G Long-Term Evolution (LTE) signal in Nigeria. T...

Lte Cellular Network

In this paper we have studied downlink packet scheduling algorithms proposed for LTE cellular networks. The study emphasize on three most promising scheduling algorithms such as: FLS, EXP rule and LOG rule. The performance of these three algorithms is conducted over video traffic in a vehicular environment using LTE-Sim simulator. The simulation was setup with varying number of users from 10 60...

OpenAirInterface 4G: an open LTE network in a PC

LTE 4G cellular networks are gradually being adopted by all major operators in the world and are expected to rule the cellular landscape at least for the current decade. They will also form the starting point for further progress beyond the current generation of mobile cellular networks to chalk a path towards fifth generation mobile networks. The lack of open cellular ecosystem has limited app...
