“…Another area of deployment is WPANs and wireless local area networks (WLANs). These could be in between a laptop and an access point, an information kiosk and a receiver [57], between AR/VR wearables and a modem or between the "infostations" proposed in [58]. These are very short links perhaps less than 0.5-1 m for WPANs and up to 30 m for WLANs.…”

Mobile communications have been undergoing a generational change every ten years or so. However, the time difference between the so-called "G's" is also decreasing.While fifth-generation (5G) systems are becoming a commercial reality, there is already significant interest in systems beyond 5G, which we refer to as the sixth generation (6G) of wireless systems. In contrast to the already published papers on the topic, we take a top-down approach to 6G. More precisely, we present a holistic discussion of 6G systems beginning with lifestyle and societal changes driving the need for next-generation networks. This is followed by a discussion into the technical requirements needed to enable 6G applications, based on which we dissect key challenges and possibilities for practically realizable system solutions across all layers of the Open Systems Interconnection stack (i.e., from applications to the physical layer). Since many of the 6G applications

“…The challenges include rapid user association and link establishment, beam management, error detection, and correction strategies, and secure authentication on public systems. An experimental demonstration of a prototype for KIOSK Downloading system using 300 GHz band is presented in [86] and [120], which includes the channel and LOS analysis with comparison of error correction algorithms. The approximate beam size is mentioned in [86] as 22 cm with 30 dBi as antenna gain for 1-meter distance.…”

Terahertz communication is emerging as a future technology to support Terabits per second link with highlighting features as high throughput and negligible latency. However, the unique features of the Terahertz band such as high path loss, scattering, and reflection pose new challenges and results in short communication distance. The antenna directionality, in turn, is required to enhance the communication distance and to overcome the high path loss. However, these features in combine negate the use of traditional medium access protocols (MAC). Therefore, novel MAC protocol designs are required to fully exploit their potential benefits including efficient channel access, control message exchange, link establishment, mobility management, and line-of-sight blockage mitigation. An in-depth survey of Terahertz MAC protocols is presented in this paper. The paper highlights the key features of the Terahertz band which should be considered while designing an efficient Terahertz MAC protocol, and the decisions which if taken at Terahertz MAC layer can enhance the network performance. Different Terahertz applications at macro and nano scales are highlighted with design requirements for their MAC protocols. The MAC protocol design issues and considerations are highlighted. Further, the existing MAC protocols are also classified based on network topology, channel access mechanisms, and link establishment strategies as Transmitter and Receiver initiated communication. Open challenges and future research directions on Terahertz MAC protocols are also highlighted.

“…An unrelenting trend in the evolution of wireless communications is the move to ever higher frequencies, so as to exploit ever wider bandwidths. The current frontier is at mmWave frequencies, but researchers already have their eyes set on sub-terahertz bands where new applications await, including kiosk information transfers [1], wireless backhaul [2], and wireless interconnections within datacenters [3].…”

We establish an upper bound on the informationtheoretic capacity of line-of-sight (LOS) multiantenna channels with arbitrary antenna arrangements and identify array structures that, properly configured, can attain at least 96.6% of such capacity at every signal-to-noise ratio (SNR). In the process, we determine how to configure the arrays as a function of the SNR. At low-and high-SNR specifically, the configured arrays revert to simpler structures and become capacity-achieving.
