7Layers offers ECC Testing for a MIMO LTE Enabled Device
7Layers is pleased to announce that it is the first independent test lab to measure Envelope Correlation Coefficient. ECC and its measurement is an important parameter to be considered while developing an LTE device supporting MIMO antenna system. 7Layers ability to test and measure the ECC represent a major step forward in helping LTE devices reach higher spectral efficiency and achieve faster data rates.
MIMOOne of the main parameters to characterize the effect of correlation in an LTE device is ECC. ECC is a calculated value from the measurements of radiated total isotropic sensitivity using a test methodology from CTIA v3.1 called ‘Alternate TIS Test Procedure based on Receive Signal Strength’. Measurement of ECC helps understand the design and efficiency of MIMO antenna systems.
Much of R&D and simulations regarding ECC has been done, but for practical considerations 7Layers helps device manufacturers and carriers to determine the diversity gain and spectral efficiency by testing and measuring this important parameter.
