Weak network strength for the wireless communications may cause latency that results in a suboptimal user experience. To improve operations of the head-mounted device, the head-mounted device may predict a change in network strength associated with the wireless communications. The head-mounted device may predict changes in network strength based on historical network strength data and/or scene understanding data for a physical environment. In response to predicting the change in the network strength, the head-mounted device may change a characteristic of the wireless communications. The head-mounted device may change a forward error correction applied to the wireless communications, change a bit rate of the wireless communications, and/or change a number of retries during the wireless communications. ## Claims ### Claim 1 A method of operating an electronic device comprising one or more sensors, the method comprising: exchanging wireless communications with external electronic equipment;
