LTE is now widely established as a mobile broadband solution on a global basis. It aims to provide a concise synopsis of how LTE operates, focusing on the driving factors behind LTE, as well as the architectural view of an LTE deployment.. Operational procedures such as network attach and bearer utilization will be examined, as well as key mobility and roaming considerations.
With Release 10 of the 3GPP specifications came the introduction of LTE Advanced, a suite of radio related improvements designed to push the data rates and capacity of LTE even higher. Techniques explored includes the use of Carrier Aggregation, SON, VoLTE and IMS, across the air interface signalling protocols to support these new features. It also features E-UTRAN related improvements, including the required enhancements to X2 in support of mobility and management.
