The LTE system includes a new E-UTRA physical layer based on OFDMA and SC-FDMA, as well as defining various frequency bands and bandwidth options. The course details the radio network design process, incorporating the available options in LTE. As such, it examines the requirements and considerations a planner needs when designing LTE coverage and capacity. Those attending should have a good understanding of LTE operation and the LTE air interface ie mpirical’s LTE System Engineering and LTE Air Interface courses.
