Aspects of the subject disclosure may include, for example, attaching, by a radio circuit, to a terrestrial radio network for radio communications with the terrestrial radio network, monitoring an altitude of the radio circuit relative to a surface of earth, and attaching, by the radio circuit, to a non-terrestrial radio network for subsequent radio communication with the non-terrestrial radio network to limit radio interference on the terrestrial radio network, wherein the attaching to the non-terrestrial radio network is responsive to the altitude of the radio circuit exceeding a first elevation threshold value. Other embodiments are disclosed.

A lightweight, efficient, autonomous sub-surface water data profiler (10) that can be easily programmed and deployed to collect sample data at a variety of water depths is disclosed. The profiler is a unique, simple-to-use, low-cost design with a low-cost depth control system that allows several dive / surface trips, an Android graphical interface for Bluetooth programming and a deployable antenna for retrieval after completing its mission. The collected data is achieved using an open-source Android interface and Bluetooth programming using Android and longer-range radio communications with a deployable antenna. The profiler is usable by anyone with a deep pond, lake, ocean or even a pool that they would like to monitor.

A computer-implemented method, performed by a first node, for handling location of a network node in a geographical area for operation in a communications system. The first node obtains first data indicating images of the geographical area over a first time period. The first node also obtains second data indicating data samples of performance indicators of radio communications, during the first time period, of devices in the geographical area. The first node determines, by performing a spatio-temporal correlation of the obtained first data and the obtained second data, one or more locations as candidates to place the network node for operation in the communications system. The determining is performed using machine learning or deep learning, and. The first node then outputs an indication of the determined one or more locations.

This invention discloses a method for active interference signal-to-interference ratio (SIR) analysis of aircraft radio communications. The method includes: acquiring aircraft track data, ground station coordinate data, and interference source coordinate data, and mapping them uniformly to a three-dimensional coordinate system; obtaining the interference limit of the interference source at a reference distance and obtaining the reference interference field strength at the reference distance through correction processing; constructing a free-space propagation model of the active interference source, calculating the minimum distance between the aircraft's track point and the interference source, and obtaining the interference signal strength at the track point from the free-space propagation model; calculating the signal strength between the ground station and the aircraft at the track point, and calculating the SIR in decibels at the aircraft's airborne receiver at the track point. This invention can quickly generate SIR curves for interference assessment analysis of different interference sources on aircraft at different flight segments or different locations, significantly improving the accuracy and comprehensiveness of active interference analysis for airborne equipment.

This invention discloses a multi-submarine unmanned mother-daughter submersible, belonging to the field of marine engineering equipment technology. The submersible includes a mother submersible and daughter submersibles. The mother submersible has a recovery device at its bottom and a winding mechanism inside. A pair of auxiliary stabilization devices are located on both sides of the mother submersible. A winding mechanism is located above the daughter submersibles, connected to a connection system. The top of the connection system has the daughter submersible recovery device. This invention utilizes radio communication technology to control the multi-submarine unmanned mother-daughter submersibles for marine environmental monitoring. It replaces manual labor while increasing the surfacing speed of the daughter submersibles during recovery and preventing them from becoming detached. The entire device maintains high stability in the water during recovery and can adapt to harsh environments.
