MIMO (Multiple Input, Multiple Output), is an advanced radio technology which increases the data capacity of a narrowband network without requiring more spectrum.    We incorporate two transceivers in each Tornado radio, operating at the same frequency and both connected to a MIMO antenna.  One transceiver is connected to the vertically-oriented part of the antenna and the other is connected to the horizontal.   This results in double the capacity of data throughput in a narrowband channel compared to a standard SISO radio.  For more detailed information on how MIMO works
