LTE-Advanced: Requirements and Technical Challenges for 4G Cellular Network

The higher peak data rates for mobile user are in demand. Audio/Video streaming, online conferences, and social media services are becoming the necessity of life. In order to fulfil the sheer amount of data need of users, robust and efficient wireless technology is needed. LTE-Advanced, which is based on Rel-10 of ITU is the solution for future mobile wireless networks. It is the promising technology for future wireless broadband network based on Rel-8 of Long term Evolution (LTE). The paper provides a higher level overview of LTE-Advanced, which includes carrier aggregation for efficient spectrum use, MIMO techniques for multiple signal transmissions and receptions, relaying and heterogeneous deployment strategy. LTE-Advanced system will be the NXGN wireless technology for years to come.
