Make Wireless Work Better
Three components :- range, reliability, and speed, help to determine the quality of a wireless network link. Although today’s wireless standards call for a maximum throughput speed of 54Mbps, actual network configurations rarely reach that speed. In traditional networks (that don’t use MIMO), each of the three components strongly affects the others; for example, manufacturers have to reduce range and reliability to increase a network’s speed, reduce speed and range to increase reliability, and so forth.
With MIMO, though, all three components can increase at the same time. MIMO takes advantage of the multiple paths a wireless signal naturally takes. A traditional radio signal (especially inside the home) bounces off objects and takes multiple paths, some of which arrive at different times at the receiver. This process causes interference problems for a traditional radio system; the system often sees the multiple paths as “blurred” or “weakened” because they’re carrying the same data and interfering with one another. This problem also shrinks the coverage area of the network.
However, a MIMO system splits its signal to take advantage of this natural effect. With each multiple path carrying a unique signal, which helps overcome interference, the overall signal carries more data. Also, the antennas using MIMO technology work together to find the clearest data path.
MIMO delivers greater spectral efficiency than a traditional radio signal, which increases range, reliability, and speed, all simultaneously.
