Optical/radio local access network

A controller comprising a wireless transceiver, the controller performing operations comprising:

• detecting an optical received signal strength of a free space optical channel of a network route falling below a threshold level, wherein the network route comprises a first group of nodes of a plurality of nodes of a wireless network;
• sending control signals to the plurality of nodes via the wireless transceiver;
• receiving an alarm responsive to a signal strength of an optical receiver in a node of the plurality of nodes falling below a threshold level;
• and
• initiating a reconfiguration of the plurality of nodes of the wireless network according to an alternative network route responsive to the detecting of the optical received signal strength falling below the threshold level, wherein the initiating of the reconfiguration of the plurality of nodes comprises sending commands by way of a land line link.
