A method of measuring the physical and chemical properties of tissue or cells and a device for the same is provided, with which the physical and chemical environment of the tissue or cells can be changed arbitrarily corresponding to experimental necessities. By discontinuing useless closed-loop MIMO communication and switching to the open-loop MIMO communication mode that is better than Zero-forcing, the decoding characteristics are prevented from simply becoming deteriorated. An automatic network reconfiguration module automatically reconfigures network data connectivity in the event that an indication has been provided that data network connectivity does not meet performance or configuration criteria. A controller is configured to remotely instruct the set-top boxes to access content from the network and to monitor the operations of the set-top boxes, and an analyzer is configured to monitor the quality of the transmissions received.
