“…Although wireless positioning technology has been significantly developed, there is still a large room for improvement. Taking the RSSI positioning technique as an example, there are many interfering factors in the spatial propagation of RSSI [93], which lead to a certain degree of error, either by using database matching or by using a distance-based model [94]. How to effectively address this error due to communication propagation requires further research and exploration.…”

Location-based services are now playing an integral role in the development of emerging industries, such as the Internet of Things, artificial intelligence and smart cities. Although GPS, Beidou and other satellite positioning technologies are becoming more and more mature, they still have certain limitations. In order to meet the needs of high-precision positioning, wireless positioning is proposed as a supplementary technology to satellite positioning, in which the Received Signal Strength Indication (RSSI) is one of the most popular positioning methods. In this paper, the application scenarios, evaluation methods and related localization methods of wireless positioning based on RSSI are studied. Secondly, the relevant optimization methods are analyzed and compared from different angles, and the methods of RSSI data acquisition are described. Finally, the existing problems and future development trends in RSSI positioning methods are expounded, which has certain reference significance for further research on RSSI localization.

“…The irst factor is the installation positions of BSs within an indoor environment. As detailed in [64], we conducted an investigation into the effect of BS locations on TDoA accuracy in various simulated environments. The conclusion drawn from this investigation was that Geometric Dilution of Precision (GDoP) calculations can serve as a viable alternative to time and power-intensive simulations.…”

“…The gray area size and shape illustrate how moving only one BS, Rx3, in, otherwise, the same setup can degrade the positioning accuracy. This opens the door to investigate how different BS constellations can result in different positioning accuracy, and how the optimization process proposed in [64] can be utilized in a real-life implementation to get the optimum BS constellation to achieve higher accuracy.…”

“…After the establishment of the SeRANIS B5G testbed with both its indoor and outdoor components, a validation of the GDoP approach and the simulation outcomes from [64] can be performed through a measurement campaign conducted exclusively within the indoor segment of the network. Furthermore, the inclusion of a suf icient number of outdoor BSs enables the assessment of TDoA positioning performance, facilitating the creation of accuracy maps.…”

In recent years, Non-Terrestrial Networks (NTNs) have gained increased attention from the 3rd Generation Partnership Project (3GPP) due to their potential to enhance cellular networks by improving coverage, resiliency, and reliability, especially in rural areas and disaster scenarios. The upcoming Sixth-Generation (6G) cellular networks aim to establish layers of cells at different altitudes with Base Stations (BSs) on Earth and in space, providing a seamless user experience. Testing and experimentation are crucial for realizing this ambitious vision. University of the Bundeswehr Munich (UniBw M) is deploying a Beyond 5G (B5G) and 6G testbed comprising both space and ground segments. The space segment of the testbed is composed of the ATHENE-1 satellite that is going to be launched in 2025. The ground segment includes the satellite ground station with several full motion antennas for the radiofrequency links and an optical ground station for the free-space optical link based on laser technology, while the Terrestrial Network (TN) component is deployed using a Fifth-Generation (5G) Non-Public Network (NPN) with multiple gNodeBs (gNBs) and multiple 5G core solutions. In its current state, the testbed includes various measurement equipment and emulators in the 5G Lab, a Gnb with two active cells, a core network, a satellite ground station, and a mobile 5G on-the-move solution. This testbed allows various experiments including interference management between existing networks, positioning and localization, Public Protection and Disaster Recovery (PPDR) using Multi-Access Edge Computing (MEC) and NTN. This paper describes the components of the Seamless Radio Access Networks for Internet of Space (SeRANIS) B5G testbed, the current status, future deployment plan, preliminary test results, and planned tests.
