Long Term Evolution - LTE Test

LTE is still growing, adding subscribers around the world. The technology is evolving to LTE-Advanced and to LTE-Advanced Pro, adding measurement challenges at every step. Keysight is there to provide insight into your designs that optimize and integrate these technologies and to meet the latest standards. Our solutions reduced design uncertainty, provide faster and easier development of high-performing LTE products and help you find root causes faster. As an active member of 3GPP and other influential wireless standards bodies and leading 5G forums and consortia, we have been at the forefront of providing standard-compliant LTE test and design tools across the entire lifecycle– from simulation to R&D, design verification and pre-conformance, conformance, manufacturing, through network deployment and service assurance.

Our engineers, experts in design and test, are available to advise, assist and augment your teams all around the world. Our expertise is also readily available through white papers, application notes and webcasts for LTE, LTE-Advanced, MIMO, WLAN Test, and 5G.
