3 Keysight LTE and LTE-Advanced Solutions - BrochureKeeping Pace with TechnologyLTE-AdvancedMoving Forward to Increase CapacityLTE-Advanced is the evolved version of LTE that is being developed by 3GPPto meet or exceed the requirements of the International TelecommunicationUnion (ITU) for a true fourth generation radio-communication standard known asIMT-Advanced. LTE-Advanced is defined in Release 10 and all the follow onreleases including Release 12. LTE-Advanced is focused on higher capacity withincreased peak data, higher spectral efficiency, increased number of simultaneouslyactive subscribers and improved performance at cell edges.TD-LTEEvolving LTE Specifications — from FDD-LTE to TD-LTEFollowing the integration of the Chinese TD-SCDMA standard, based on TimeDivision Duplex (TDD), into the 3GPP specifications for LTE, chipset and devicedesigners are now working to include TDD capability. Now known as TD-LTE, thestandard caters to the asymmetric needs of mobile data usage, and allows carriersto make use of the unpaired spectrum that many of them already own. Keysight wasthe first to provide solutions for testing this new technology and currently offersTD-LTE solutions from design simulation to signal generation and analysis.MIMONew Multiple Input Multiple Output Transmission ScenariosThe specified RF environment for LTE includes not only basic signal transmissionand reception, but also multiple input multiple output (MIMO) scenarios with upto four separate transmitters and receivers. For module and component test,complex frame-based test signals are passed through the device under test andmeasured using vector signal analysis to determine EVM and CCDF. Keysight offersa complete set of design and test solutions for MIMO technology—from designsimulation to signal generation and analysis through manufacturing anddeployment.Heterogeneous NetworksAdding to the LTE Architecture with Small CellsAnother way to expand capacity is with small cells. Small cells offer flexibility,bring down the costs of installation and lower power usage but they also bringalong test challenges such as interference design and test and the need for lowercost manufacturing. Building on our demonstrated history of leadership and proventrack record delivering base-station test equipment, Keysight offers small celldesign and test solutions to help you meet your design and production-cost goals.
