A survey of single and multi-hop link schedulers for mmWave wireless systems

Abstract

Wireless communication at 60. GHz, aka mmWave, provides extremely high data rates, i.e., several Gb/s. Moreover, devices have a much shorter transmission range as compared to those operating in the 2.4 and 5. GHz bands. Indeed, links can be treated as pseudo-wires with minimal interference leakage. As a result, future 60. GHz systems will have very high spatial reuse. This, however, is at the expense of high propagation loss, which can be overcome using directional or smart antennas. Another promising solution is to employ relays to boost the signal of weak links. In particular, if relays are properly selected, they are able to offer higher data rates than direct links, and also help circumvent obstacles. To this end, we review state-of-the-art schedulers that take advantage of the high spatial re-use afforded by 60. GHz wireless systems to activate multiple links within a channel time allocation. Moreover, we survey works that use passive and active relays to overcome obstacles and to facilitate novel applications. We also survey those that maximize both spatial reuse and throughput of both direct and indirect (relay) links simultaneously.

NLOS Identification and Machine Learning Methods for Predicting the Outcome of 60GHz Ranging System

“…The 60GHz spectrum has many potential applications involving navigation communications and 8K digital cameras. Compared with the traditional wireless communication systems, it has obvious advantages of at least 5GHz of unlicensed spectrum [1] , robustness to interference [2] , precise time and multipath resolution [3] , and high spatial reuse [4] . This makes 60GHz unlicensed band promising technology to achieve gigabit wireless networks including fifth-generation cellular networks [5,6] and wireless body area networks [7] .…”

Detailed analysis of energy detection‐based millimetre‐wave time‐of‐arrival measurement system

“…Advances in 60 GHz extremely high‐frequency band have drawn wide concerns due to its large bandwidth, better resolution, and the mitigation of the interference frequencies [1–3].
