5G-Enabled Tactile Internet

Abstract

Abstract-The long-term ambition of the Tactile Internet is to enable a democratization of skill, and how it is being delivered globally. An integral part of this is to be able to transmit touch in perceived real-time, which is enabled by suitable robotics and haptics equipment at the edges, along with an unprecedented communications network. The fifth generation (5G) mobile communications systems will underpin this emerging Internet at the wireless edge. This paper presents the most important technology concepts which lay at the intersection of the larger Tactile Internet and the emerging 5G systems. The paper outlines the key technical requirements and architectural approaches for the Tactile Internet, pertaining to wireless access protocols, radio resource management aspects, next generation core networking capabilities, edge-cloud and edge-AI capabilities. The paper also highlights the economic impact of the Tactile Internet as well as a major shift in business models for the traditional telecommunications ecosystem.

5G IoT Industry Verticals and Network Requirements

“…Remote control, as discussed by Simsek et al (2016), is an application that can be particularized to many industries: remote control of heavy machineries, factory automation or real-time monitoring of industrial plants.…”

“…As a further step, the disruptive technologies enabling the deployment of 5G systems aiming at introducing flexibility, customization and re-configurability of the network in both radio and core segments, will enable the provisioning of enhanced IoT services interconnecting people and everything. Indeed, a natural evolution of connecting devices to the Internet, is to remotely control these devices through the Internet; machines are not only able to talk to each other, but 5G is also focusing on enabling novel industry-related IoT applications in both consumer and business environments, for instance to increase industry automation, remote control and tactile Internet applications (Simsek et al, 2016). This Chapter will cover the main trends in the industry to use the IoT to tackle several problems or to improve outcomes: business-to-business (B2B) market, increase in automation and remote control/operation, cost reduction, efficiency improvement.…”

“…In the existing robotic surgery devices, there is currently no feedback for the stiffness or any haptic information and adding these capabilities would reduce the doctor's reliance on video and sound transmission. Above mentioned aspects are discussed by Simsek et al (2016).…”

Generalized degrees-of-freedom of the 2-user case MISO broadcast channel with distributed CSIT

“…Other scenarios featuring existing backhaul links may favor local processing over centralized one in order to meet the tight latency constraints derived from 5G and tactile internet applications [4]. In these cases, a full CSI sharing across TXs is not always desired, and there is a need for robust processing on the basis of locally available CSI.…”

Improvement of Operationality Under Time Varying Delay for Bilateral Teleoperation Systems by Differential Signal Based Data Modulation

“…The development of network technology such as 5G, allowed bilateral teleoperation systems to be more attractive to the society (1) . A bilateral teleoperation system is a system consisting a master and a slave system and tactile sensation is transmitted between the two systems.…”
