MIMO External Antenna Configuration (with Omni-Directional and Directional Yagi Antenna) for 4G LTE/ 5G NR Sub 6GHz Application

Shown in this drawing is a Multi-WAN router which combines multiple Cellular or other ISP Internet connections for increased bandwidth. Cellular reception is improved with use of Omni-directional and Directional Yagi antenna.

For example, if you have multiple LAN clients that need to concurrently upload or download data using a cellular connection, you may combine multiple cellular (see more on dual modem for dual cellular connectivity) connections to improve average speed per client or for redundancy/failover.

Devices supporting MIMO configurations employ special coding on signals from different transmit antennas in multipath propagations to improve signal reception. 

For transmit/receive diversity, multiple receive/transmit antennas are used at the receiver/transmit to increase the probability of detecting the signal from a single or multiple transmit/receive antennas. No MIMO-coding is used in this case.

Provide proper separation between the MIMO antennas (or proper isolation of the antennas) to take advantage MIMO or Diversity configs (See more here)
