“…Susceptibility to attenuation and blockage, including bad weather, buildings and even human bodies, challenges the use of highly directional mmWave beams in a number of emergency scenarios, in particular if combined with mobility [1]. Examples include indoor and underground rescue operations, directional backhaul mmWave links or the use of UAVs and robots in disaster scenarios [28]- [31] Most promising candidates to address the problem of variable channel quality are beam tracking and beam alignment protocols, the use of which for PPDR, however, remains to be investigated.…”

Today, legacy PMRs continue to be the only group of tested, verified and certified technologies for the Public Protection and Disaster Relief (PPDR) sector. For the fifth generation (5G) to follow suit, substantial hands-on experimentation with functional, architectural and deployment aspects is required, and further test trials need to take place in order to inform and enable future verification and certification procedures for 5G to become a proven PPDR technology. This paper studies 5G PPDR experimentation associated with novel virtualized and cloud-native 5G technologies, architectures and deployment options, as well as feasibility studies and field performance and verifications trials involving vertical-specific 5G infrastructures and applications. Key enabling technologies, such as massive multiple input multiple output (MIMO), device-to-device (D2D), network slicing and multi-access edge computing (MEC) are discussed and 5G PPDR architecture and deployment options are investigated. A dedicated 5G PPDR experimentation facility is presented, and a case study of hands-on experimentation is provided. Two distinct scenarios are discussed, i.e., emergency augmentation of the terrestrial 5G PPDR network with rapidly deployable on-site capacities in the area of a public safety incident, and availability and reliability of decision-support PPDR applications on the field. Experience with the deployment and verification insights are accompanied by the results of quality of service (QoS) and non-functional key performance indicators (KPI) assessment that were exhibited during the experiment. The experimentation outcomes confirm the ability of the facility to support emulated laboratory experimentation specifically designed to tackle 5G challenges for this particular vertical as well as field studies recreating realistic public safety operations.INDEX TERMS 5G, mobile communications, public safety, public protection and disaster relief, mission critical communications, network architecture, network deployment, experimentation, field trial.

“…In [14], the use of millimeter wave multibeam transmission mode in the satellite layer network was considered to increase the overall network capacity, which can be mutually confirmed with the VANET capacity calculated by us. In [15][16][17][18], their researches are aimed at improving the performance of the network through the algorithm of resource scheduling and obtaining the maximum network capacity by assigning different bandwidths to different nodes. Research on the control of output power mode in order to pursue a more optimal network capacity is reflected in [19][20][21][22]; different nodes choose different transmit powers according to different task requirements, which can effectively improve the throughput of the topology.…”

The development of multibeam directional transmission technology used in vehicular ad hoc networks is drawing much more attention in recent years due to its wider coverage ability than omnidirectional transmission. In this paper, we analyse the transport capacity of the vehicular network using different antenna modes in the transmitter and receiver end, respectively. We first construct the cross-layer model comprising the characteristic of the directional antenna model, arbitrary network model, and interference model. Then, based on scaling laws, we calculate the upper and lower bound of the network capacity with and without the directional multibeam transmission technology. In order to reduce the capacity lower bound computation complexity, several topology frameworks are constructed while taking various interferences into account included in the actual project. Finally, we analyse the capacity under changes of different parameters and also evaluate the law of capacity changes to discover how much improvement multibeam transmission technology can bring to the network performance. Analysis shows that compared with DTOR and OTDR mode, DTDR mode can continue to increase network capacity by 2 to 3 times on the basis of the above two modes.
