1. An aircraft system comprising:

  • a first transceiver configured to transmit and receive radio signals in a first millimeter wave (mmW) frequency band via a first antenna;

    a second transceiver configured to transmit and receive radio signals in a second mmW frequency band via a second antenna;

    a processing unit coupled to the first transceiver and the second transceiver;

    wherein the processing unit is configured to provide data signals to the first and the second transceivers for transmission and to receive demodulated signals from the first and second transceivers;

    wherein the processing unit is further configured to output signals to alter orientation of the first antenna through which to establish a first point-to-point connection with a first aircraft and to output signals to alter orientation of the second antenna through which to establish a second point-to-point connection with a second aircraft;

    the first point-to-point connection and the second point-to-point connection forming part of a point-to-point aircraft relay ring network communicatively coupling a plurality of aircraft in a shared flight route area to each other; and

    wherein the processing unit is further configured to compare characteristics of signals, received from the second aircraft via the second transceiver, with a model relating signal characteristics to weather to determine weather conditions of an area through which the received signals passed.
