RF Design Workshop: Part 2 - VoLTE and Small Cells
LTE_416x | Expert-Led Live | LTE and VoLTE | 3
Course Duration: 2 days
With the expected introduction of LTE features such as Voice over LTE (VoLTE), multi-frequency, small cell deployment, and LTE-Advanced features such as carrier aggregation, the existing RF design process needs to be enhanced. This workshop provides a foundation for the features such as VoLTE, carrier aggregation, Heterogeneous Networks (HetNets), and small cells. The course revisits the data traffic driven link budget and enhances to reflect the VoLTE performance requirements and the differences for small cells. The antennas being planned to accommodate multi-band deployments are discussed. Various RF parameters related to cell selection/re-selection and handover are discussed for proper load distribution in cases of multi-carrier and small cell deployment. In summary, this workshop provides detailed understanding of RF design enhancements for VoLTE, LTE-Advanced and small cell.
