Mastering LTE Air Interface Instructor Led | Duration: 2 Days

Long Term Evolution (LTE) is a 4th generation (4G) wireless technology which promises a much higher air interface data rate (over 100 Mbps) to users while reducing the cost per bit for wireless service providers. The building blocks of LTE include OFDM, multiple antenna techniques, and all-IP technologies. Multiple antennas can increase data rates, throughput, coverage, and lower battery consumption in a mobile device. This course provides an in-depth discussion of the PHY and MAC layers of the LTE air interface. First, it introduces the LTE/E-UTRAN network architecture and protocols. It then provides comprehensive coverage of the PHY frame structure, channels, resource allocation, and multiple antenna techniques. Finally, the course discusses the operations of acquisition, system access, data session setup, DL and UL traffic operations and handovers. Intended Audience This is a detailed technical course, primarily geared for a technical audience including those in product design and development, integration and testing, and system engineering. Learning Objectives After completing this course, the student will be able to:

Sketch the LTE/E-UTRAN network architecture and associated interfaces and protocols

Sketch PHY frame structure and resource mapping for DL and UL List PHY channels in DL and UL and map them on the frame

structure Describe the synchronization operation and use of reference signals Explain PHY layer operations and measurements Step through system acquisition and data session setup procedure Describe traffic operations in DL and UL at the PHY/MAC layers Explain key concepts of LTE mobility and handovers at the PHY layer Identify the key multiple antenna techniques and describe their

applications
