LTE Carrier Aggregation Technology Overview
LTE Carrier Aggregation Technology Overview discusses how the key concepts behind carrier aggregation. LTE-Advanced LTE Carrier Aggregation combines carriers at the device to increase the user downlink rates across the cell coverage area under typical network loading conditions.
Carrier aggregation used technique of the LTE Advanced standard, bonds together disparate bands of spectrum to create wider channels and produce more capacity and faster speeds as a benefit.
Learn how the increased data rates of carrier aggregation, utilizing all spectrum resources, is a trade-off to more capacity for bursty applications allowing HetNets to make best use of spectrum including higher bands for small cell (35 GHz) and lower bands (700 MHz) for macros.
LTE Advanced introduces different dimensions of LTE improvements including: wider bandwidth, carrier aggregation across multiple carriers, multiple bands, and across licensed and unlicensed spectrum.
LTE Carrier Aggregation Technology Overview is a detailed technical course intended for those in LTE systems and network engineering and design, LTE-Advanced system planning and integration, LTE-Advanced Systems verification and validation, testing, systems engineering, network operations, and anyone else who needs a technical overview of CA.
