Introduction Long Term Evolution Release 10 is the solution that the 3rd Generation Partnership Project (3GPP) partners came up with, to accommodate the increasing demand of higher transmission rates, lower latencies and IP-based architecture mobile networks. LTE-Advanced is the first technology that fulfilled IMT-A requirements for 4G networks and it has become an available technology since the first half of 2011. 4. Features of LTE-A Peak data rate A downlink peak data rate of 1 Gbps and an uplink of 500Mbps for stationary users. And up to 100 Mbps for roaming. Latency Very Low, Little setup time (350 Mbps Peak Data Rates UL: 300 MbpsUL: > 200 Mbps various frequenciesSpectrum2.3, 2.5, 3.5, 5.8 GHz(700 MHz frequency)DL: 30 bps / HzDL: > 2.6 bps / Hz (2 x 2)Spectral EfficiencyUL: 15 bps / HzUL: > 1.3 bps / Hz (1 x 2) Link layer: < 5 ms Link layer: < 10 ms Latency Handoff: < 50 msHandoff: < 30 msCoverage Up to 100 kmup to 50 km 22. LTE-A in The Market 23. Applications of 4G LTE 24. Applications VoIP (VoLTE) and high definition videos streaming 25. Applications Support cloud computing applications and isprofitable to both users and vendors. 26. Applications Allows the digitization of everyday life where allpeoples needs are being fulfilled by embeddedapplications. 27. Applications Virtual Clinics, creating seamless integrated healthenvironment. 28. Applications 4G networks provide a huge advantage to thedevelopment of smart grid technologies 29. Whats Next? 4G network coverage will be as much as the current 3Gcoverage around the world by the end 2013. 4G has already started work on Release 11: objectives of features & study items supporting QoS improving the spectrum capacity some more. For beyond Rel-11, brand new features with very biggain are needed to meet long-term requirements. 30. Description Adoption of LTE technologyDateJanuary 5, 2012SourceGSA - The Global mobile Suppliers Association 31. Conclusion LTE-Advanced has been the first released 4G technology,but it most certainly isnt going to be the last. With the key technologies designed in this release, itbecame easier for engineers to use it as a step stone forfurther releases and new approaches.And since the demand on high speed and reliableconnections is increasing everyday, it wont be long tillthe next technology is released to the public. 32.
