-The antenna is managed through a combination of hardware and back-end services.
+The antenna is managed either directly by the USRP via a fast GPIO-to-RS485 link or through OMF services which facilitate the selection of power state and pattern selection.

-The antenna switching hardware is shown in Figure 6. It consist of: bank of RF switches, RS-485 drivers and ''Raspberry PI'' as an embedded controlled. This hardware enables remote antenna selection and steering.

-The bank of switches is used to route both nodal !WiFi and X310 antenna feeds to either regular antennas or to directional or omni-directional antennas on FCI-3740. The table below shows switch states and corresponding antenna selections (blanks indicate the particular switch state does not matter).
