Systems and methods for improving the quality of millimeter-wave communication

A method for compensating for changing path-loss conditions in a millimeter-wave communication network, comprising:

• communicating point-to-point, at a second millimeter-wave frequency having a second atmospheric absorption rate, between a first and a second millimeter-wave communication systems over a predetermined distance resulting in a second path-loss associated with said predetermined distance;
• detecting a change from said second path-loss to a first path loss associated with said predetermined distance;
• and
• switching from said second millimeter-wave frequency to a first millimeter-wave frequency having a first atmospheric absorption rate which is different than said second atmospheric absorption rate, such that said difference substantially compensates for said change in path-loss conditions.

A method for optimizing inter-link interferences by exploiting atmospheric absorption of millimeter-waves:

• communicating point-to-point, at a first millimeter-wave frequency having a first atmospheric absorption rate, between a first and a second millimeter-wave communication systems resulting in a first path loss;
• concluding that said communication has a surplus system gain in respect to said first path loss;
• and
• increasing said first path loss to a second path loss by switching from said first millimeter-wave frequency to a second millimeter-wave frequency having a second atmospheric absorption rate which is higher than said first atmospheric absorption rate, thereby adjusting said first path loss to a second path loss that is higher than said first path loss, thereby making use of said surplus system gain.

A system comprising a millimeter-wave communication network configured to react to changing communication conditions by exploiting atmospheric absorption rates, comprising:

• a first millimeter-wave communication system;
• and
• a second millimeter-wave communication system configured to communicate point-to-point with said first millimeter-wave communication system, at a first millimeter-wave frequency having a first atmospheric absorption rate;
• wherein at least said first millimeter-wave communication system is configured to:
• (i) detect a change in at least one communication condition associated with said communication, and (ii) switch from said first millimeter-wave frequency to a second millimeter-wave frequency having a second atmospheric absorption rate which is different than said first atmospheric absorption rate, thereby operative to react to said change.
