A Study on Pre-4G (LTE and WiMAX) Protocols Towards 4G-ITU Requirements
The Fourth Generation (4G) mobile wireless network is the current emerging mobile technology that is being run into many mobile industries which are efficiently spread around most of the world. The Pre-4G protocols are currently taking place in the commercial markets due to many features that are improved in them. However, they lack some of the features that make them act as a real 4G-ITU requirement which in turn made these pre-4G protocols not fully satisfy the demands of users. Therefore, the pre-4G protocols, specifically, the Long Term Evolution (LTE) and the WiMAX have lately emerged as they are the most two common protocols that generally act as a real 4G-ITU requirement, physically, they are however considered as 3.9G mobile systems.
