3G Americas Publishes Report on Smart Antennas
The trade association, 3G Americas has announced the publication of an educational report on the topic of smart antenna systems - also known as multiple-input multiple-output (MIMO) technology. Smart antenna, or MIMO, technology is commonly defined as, the use of two or more unique radio signals, in the same radio channel, where each signal carries different digital information, or two or more radio signals that use beam forming, receive combining and spatial multiplexing (SM). Relative to a traditional 1x1 antenna system, a 2x2 MIMO system is expected to deliver significant cell throughput gain. more
