Joint Communication and Positioning of UAV with Multiple Base Stations
To address the trade-off issue in the performance of multi-base station and multi-UAV communication and localization, research is conducted on the multi-base station carrier

The problem was formulated as a circle placement problem, after which a heuristic algorithm was developed to estimate the optimal 3D position that enhances the coverage area
It completes the Evercor offering of Airbus Defence and Space and Alcatel-Lucent for mission-critical broadband, enabling larger data transmission by using existing PMR networks.
Some networks can achieve a better balance and distribute radios to use base stations more cleverly. This is possible with a mechanism called
Because the hybrid base station TB4 can handle both 4G/5G and TETRA technology, it is easier and more cost-effective to them in parallel. Highlighting Airbus ecosystem approach.
We analyze the effect of the aerial base station (ABS) height and transmit power on the system''s downlink and uplink data rates while accounting for the reciprocal interference

We formulate an optimization problem to satisfy the access quality of service (QoS) requirements. This problem is a mixed-integer nonlinear programming problem. Therefore, we divide it into
DRAIMS that began to equip new Airbus aircraft in 2022 has caused at least 10 incidents in two years, French accident investigation bureau (BEA) says.
Some networks can achieve a better balance and distribute radios to use base stations more cleverly. This is possible with a mechanism called load-directed roaming.

The Airbus TETRA system is scalable from a local to a nationwide network. Additionally, we offer two choices for easy setup: The TB4, developed through a partnership between Airbus and Nokia, is a hybrid base station that supports both TETRA and 4G/5G technologies.
This is because, in both deployment scenarios, the UAV-BS still has to move from one hovering position or one LS to another which also requires communication and control from the ground station. In addition, we assume that the UAV-BS always maintains some amount of energy to reach the required LS.
By adopting the LS approach to UAV-BS deployment, a significant amount of energy can be saved and the service time of the UAV-BS extended because the UAV-BS does not have to continually hover in the air to provide coverage to ground users within a location.
Recently, the use of unmanned aerial vehicles (UAVs) for wireless communications has attracted much research attention.
