LTE offers significant improvements over previous mobile wireless systems in terms of data speeds and capacity, through the use of technologies such as OFDMA and multiple antenna techniques. However, these gains are realized only with careful planning and design in the LTE Radio Access Network (RAN), to maximize the efficiency of available RF spectrum. This hands-on workshop guides participants through the theory and practice of RF design for LTE RANs. Participants will apply their understanding of the LTE air interface physical structure and related concepts to calculate the link budgets to support the market coverage and performance requirements. Participants will use coverage prediction tool for exercises to apply their knowledge and skills to real-world scenarios.

Required Equipment: PC laptop with administrator privileges

This workshop is intended for LTE RF design and system performance engineers.

After completing this workshop, the student will be able to:
• Apply a consistent process to radio network design
• Use RSRP and RSRQ measurements to assess LTE RAN RF performance
• Map network requirements to corresponding system parameters
• Construct uplink/downlink link budgets to meet specific performance requirements
• Use coverage and capacity requirements to determine the optimal radio network design
• Exploit multiple antenna techniques to optimize coverage and performance
