LTE is among the prime wireless access cellular technologies in the fourth generation (4G) standard. LTE is anticipated to offer a theoretical net bit rate capacity of up to 100 Mb/s per sector in the downlink and 50 Mb/s per sector in the uplink if a 20 MHz channel is used. These data rates can be further increased if multipleinput multiple-output (MIMO) technology is adopted. At the same time LTE marks the tran- sition from a circuit-switched to an all-IP net- work architecture enhanced with greatly improved QoS characteristics such as low packet transmission delays (smaller than 5 ms for small packets), fast and seamless handover from one cell to another supporting up to 350 km/h for high-speed vehicular communications scenarios, operation with different bandwidth allocations (scalable bandwidth up to and including 40 MHz, while operation in wider bandwidths, e.g., up to 100 MHz, is also possible). Furthermore, LTE can support a wide range of services and performance metrics (e.g., real-time and non- real-time streaming, conversational, and interac- tive services with low or high delay as well as background) in a wide range of environments such as indoor, urban, and rural.
