Antenna separation in MIMO
It is important to note that commercial MIMO systems switch dynamically between SISO, MIMO diversity, and MIMO multiplexing modes, depending on a variety of factors including the channel environment and signal quality. For example, if the signal quality is very high the system uses spatial multiplexing, and if not, it automatically switches to spatial diversity mode or even to SISO mode.
In-building systems adopt MIMO
An in-building Distributed Antenna System (DAS) is ideal for MIMO because it provides very good signal-to-noise ratio, and in-building environments provide a rich scattering environment. There are two major categories of MIMO – spatial diversity, in which the same data is transmitted over each of the multiple paths, and spatial multiplexing, in which each of the paths carries different data.
Distributed antenna systems and MIMO
MIMO technology, which made its first broad commercial appearance in 802.11n systems, is now gaining substantial momentum in wide area mobile wireless networks with the launch of LTE services. MIMO is a key technology that substantially improves network capacity and user throughput in LTE networks.
