Assessment of the Possibility of Using Point -To-Point Radio L inks in the Mimo System for Constructing the Local Area Network Backbone

The article presents the results of the research conducted to assess the possibility of replacing the wiring in the connection system of the local network backbone for constructing backup connections or for the localizations where architectonic conditions do not allow performing installation works related to structural wiring of a building. Testing laboratory environment has been developed using radio devices operating in the IEEE 802.11n standard. The paper reports the results of the transmission tests in the systems of point-to-point links using the MIMO technique to determine parameters of the data transmission performance-throughput and latency. The transfer tests in the MIMO system were conducted in the indoor and outdoor environment.
