selecting beam forming parameters for each of the plurality of antenna arrays based on the plurality of selected micro-routes;

negotiating, by at least one of the first node and the second node, beam perturbations; and

communicating at least one stream between the first node and the second node through the plurality of selected micro-routes of the plurality of antenna arrays.

2. The method of claim 1 , wherein a one of the first node and the second node includes a transmitting antenna array and another one of the first node and the second node includes a receiving antenna array, and wherein the selected micro-route links the transmitting antenna array and the receiving antenna array.

3. The method of claim 1 , wherein the first node transmits the at least one stream to the second node, and the selected beam forming parameters facilitate formation of one or more beams of the first node directed according to the plurality of selected micro-routes.

4. The method of claim 1 , wherein the second node receives the at least one stream from the first node, and the selected beam forming parameters facilitate formation of one or more beams of the second node directed according to the plurality of selected micro-routes.

5. The method of claim 1 , wherein the at least one stream includes a plurality of streams, and a stream of the plurality of streams of one of the plurality of antenna arrays is different than a stream of the plurality of streams of another one of the plurality of antenna arrays.

6. The method of claim 1 , wherein the at least one stream includes a single stream, and the single stream is communicated between the first node and the second node through the plurality of selected micro-routes by more than one array of the plurality of antenna arrays.

7. The method of claim 1 , wherein identifying the plurality of micro-routes between the first node and the second node comprises generating an RF (radio frequency) map, wherein the RF map provides at least one of a beam angle, modulation, coding, transmit power, and further includes identifying the micro-routes from the RF map.
