1Area of stationary object
If wireless communication systems transmit signals in frequency bands overlapping with altimeter frequencies, then communication coverage and connectivity are improved, but altimeter interference increases disrupting communication channels
Solution Approach 1:
The system performs preliminary detection of altimeter signals in the frequency band before initiating transmission. The network node detects the presence of altimeter signals and measures their power levels, then decides whether to transmit based on these preliminary measurements, preventing interference before it occurs
Solution Approach 2:
The transmission behavior of the network node is made dynamic based on real-time detection of altimeter signals. The system continuously monitors the frequency band and adjusts transmission decisions dynamically - transmitting when altimeter signals are absent or below thresholds, and refraining when they are present and exceed thresholds
2Reliability
If network nodes continuously monitor frequency bands for altimeter signals, then interference prevention capability is improved, but system complexity and processing overhead increase
Solution Approach 1:
The network node performs self-detection and self-measurement of altimeter signals using its own reception capabilities. The system utilizes its existing receiver infrastructure to detect signals in the frequency band and measure their power levels, eliminating the need for separate dedicated detection hardware
Solution Approach 2:
The system implements a feedback mechanism where detection results and power measurements of altimeter signals are fed back to the transmission controller. This feedback loop enables the network node to make informed transmission decisions based on current channel conditions, improving reliability while maintaining manageable complexity through structured control
3Reliability
If network nodes selectively transmit based on altimeter signal measurements, then communication reliability is improved, but transmission efficiency and productivity decrease due to potential transmission delays
Solution Approach 1:
The system takes preliminary anti-action by detecting and measuring altimeter signals before transmission, and selectively refraining from transmission when interference is detected. This prevents harmful interference to altimeters while maintaining transmission efficiency by only blocking transmissions when necessary, rather than implementing continuous transmission restrictions

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may detect a signal within a frequency band associated with an altimeter. The network node may perform a measurement associated with the signal. The network node may identify whether the measurement satisfies a threshold. The network node may selectively transmit based at least in part on identifying whether the measurement satisfies the threshold. Numerous other aspects are described.
