Spirent offers the most accurate, efficient and complete solutions for testing modern receivers.

Modern wireless technologies such as LTE (including LTE-Advanced and TD-LTE) rely on Multiple-Input Multiple-Output (MIMO) and beamforming technology to deliver higher data rates, greater coverage, and lower operational costs. However, RF testing of base station and mobile device receivers is both complex and critical.

What to Test

Progress in understanding these advanced antenna techniques has led to important advancements in optimizing next-generation networks. Key areas of verification include:

• MIMO beamforming systems (up to and including 8x2 MU-MIMO)—currently being tested for deployment in TD-LTE networks. Because TD-LTE system performance is extremely sensitive to phase characteristics, testing requires a much higher degree of phase accuracy than is required in other types of testing
• Over-the-air (OTA) MIMO testing—Testing involves complex configurations that must be easily and efficiently set up and executed
• Virtual Drive Testing—not only saves on the high costs involved in iterated drive testing, but it provides a testing scenario that includes a reliably repeatable RF environment
