“…and bandwidth allocation scheme to maximize the number of satisfied users while guaranteeing total bandwidth, backhaul capacity, minimum rate, and altitude constraints. A high-altitude platform station-assisted terrestrial SA-MBN where the wireless connection to ground station works on RF and FSO bands was proposed in [246]. Additionally, the authors developed a power allocation scheme based on geometric programming to minimize the outage probability under transmit power budgets.…”

“…In the context of resource allocation in MBNs, the application of matching theory will witness a shift from the most widely used one-to-one and many-to-one matching as well as canonical matching [201], [201], [224], [246], [274]- [277] to many-to-many matching, matching with externalities, and matching with dynamics. This is due to the presence of multi-homing devices that enable both BSs/APs and users to have multiple simultaneous connections, the mobile nature of users and satellites, and the unique constraints associated with the different frequency bands.…”

The sub-6 GHz spectrum and the millimeter wave frequency band, with its huge spectrum, have been exploited in the past years to meet the traffic demands of wireless communication networks. However, the limited and licensed spectrum of these bands cannot support the massive connectivity requirements, the exponential growth of data traffic, and the strict quality-of-service requirements for 6G and beyond wireless systems. Extremely high frequencies, such as optical and terahertz, which offer much wider transmission bandwidths with extreme data rate capabilities, are expected to play key roles in the 6G and beyond era. As a result, futuregeneration wireless networks will transition from single-band and heterogeneous networks to multi-band networks (MBNs), where various frequency bands coexist. Despite the great potential of MBNs, they face novel challenges from channel modeling, transceiver and antenna design, programmable simulation platforms, standardization activities, and resource allocation. This paper provides a tutorial overview from the communication design perspective of the various frequency bands, elaborating on the above issues. Then, we introduce and examine typical MBN architectures for future networks and provide a detailed overview of state-of-the-art resource allocation problems for existing MBNs that typically operate on two frequency bands. The considered resource allocation optimization problems and solution techniques are discussed comprehensively. We then identify key performance metrics and constraint sets that should be considered for resource allocation optimization in future MBNs and provide numerical results to depict how various system parameters and user behaviors can influence their performance. Finally, we present several potential research issues as future work for the design and performance optimization of MBNs.

“…where γ th and γth are the defined thresholds ensuring the backhaul connectivity. Such thresholds can also be considered for outage probability and probability of fade [82]. With manual or semi-automated network management in such a complicated vertical network, its capabilities will be limited, the resources will be wasted, and its operational costs will increase significantly.…”

“…Proper radio wave propagation is also needed for good wireless communication facilities for machine-to-machine communication [2], Internet of Things communication [2], and wireless sensor network infrastructure [3]. Many innovative communication techniques, such as high-altitude platform stations [4], low-altitude platform stations [5], unmanned aerial vehicles, and unmanned aerial vehicles-assisted communication protocols development got researcher's attention for improvising the outdoor backhaul links that suffer from environmental disturbances or mismatching problems in heterogeneous mediums [6]. Researchers are working on enhancing system components with higher frequency bands [7], with advancements in communication protocols for future communication system advancements.…”

Analysis of Centimeter and Millimeter-Wave Path Loss at Emergency Exit

The path loss model for indoor emergency stairs has yet to get enough attention in the literature. Large-scale (LS) path loss models for a stairwell in a 10-stair academic building are the focus of this investigation. We measured the received power with three different links with sophisticated devices and preprocessed it to find the path loss. LS empirical models can be used to determine the path loss in closed environments as the LS models yield the path loss without considering the details of the environmental configurations. Therefore, this study finds LS models-close-in (CI), alpha-beta (AB), and close-in with a frequency-weighted path loss exponent (CIF), alpha-beta-gamma (ABG), when identifying the best LS models from the measured dataset. The parameters of LS models were justified by validating with the previously reported parameters. The path loss exponents extracted from the measured dataset were slightly lower than those reported in the previous investigations. The AB model showed the minimum standard deviations for the three measurement scenarios of the four LS models studied.INDEX TERMS Emergency stair, path loss modeling, wireless communication, millimeter-wave.
