When Channel Type is set to “Single”, then Tx and/or Rx of Chain #1 (for horizontal polarization antenna) can be deactivated:
- "Chain #0" is connected to the port of the
horizontal - vertical polarized integrated antenna
(H-port for connectorised models)"Chain #1" is connected to the port of the
vertical horizontal polarized integrated antenna
(V-port for connectorised models)

Please note, the connectorized models have different the vertical and horizontal polarization correspondence to Chain #0 and Chain #1 channels. For E5-BSE, E6-BSE, E5-STE and E6-STE devices:

MIMO, MISO and SISO are defined from the perspective of the data sent by the local unit (not considering the number of physical antennas used for tx and rx like in the classical definition). Therefore, these represent local configuration options. For example, one stream of data can be sent by one chain (1 antenna) corresponding to SISO or the same stream can be sent by both chains (2 antennas) corresponding to MISO. |

The data streams are transmitted over Chain #0 (corresponding to horizontal polarization) only, lowering the performance of the link, but increasing the link distance (transmitter operates with one antenna as does the receiver; there is no diversity and no additional processing for recomposing the Rx signal):

In case of establishing the link in Compatibility Mode, please note that R5000 devices have different the vertical and horizontal polarization correspondence to Chain #0 and Chain #1 channels. For R5000 devices: | |||||||||||||||||||||||||||||||||
The picture below summarizes the link establishment between two units that are configured in different operational modes. As it can be noticed, only the combination MIMO – SISO is not functional.
