MIMO (which stands for multiple input, multiple output) was created to support environments where multiple users are trying to access a wireless network at the same time. With the expected release of 802.11ax, MIMO technology capabilities are expanding. MU stands for multi-user is wireless technology supported by routers and endpoint devices. MIMO is the next evolution from single-user MIMO (SU-MIMO), which is generally referred to as MIMO. MIMO technology was created to help increase the number of antennas on a wireless router that are used for both receiving and transmitting, improving capacity for wireless connections. Knowing the quality of the signal channel is also critical. A channel emulator can simulate how a device performs at the cell edge, can add noise or can simulate what the channel looks like at speed. To fully qualify the performance of a receiver, a calibrated transmitter, such as a vector signal generator (VSG) and channel emulator can be used to test the receiver under a variety of different conditions. Conversely the transmitter's performance under a number of different conditions can be verified using a channel emulator and a calibrated receiver, such as a vector signal analyzer (VSA). Mobile communications, along with the underlying technology that provides voice and data service, is evolving to provide higher data rates in the same frequency spectrum to an ever-growing user base. New communications standards are using multiple-input multiple-output (MIMO) techniques to maximize throughput and coverage while preserving bandwidth. MIMO takes spectral efficiency to a new level, but with better spectral efficiency comes a higher level of complexity. 💙 Love you Samsung 💙
