5G Internet of Radio Light Virtual Reality System
Abstract— Virtual Reality (VR) is a technology that is rapidly
developing, leading to a whole array of innovative commercially
viable products. Some of the challenges facing the early
development of Virtual Reality (VR) and Augmented Reality
(AR) include high cost, restricted physical movement and
laborious setup. This paper highlights several of these challenges
and outlines an architecture in which systems can require less
specialised equipment, be used with greater freedom and are
simpler to setup. This paper shows how using the correct
applications, the Internet of Radio Light (IoRL) architecture
could lead to enhanced VR experiences. Specifically, a wireless
six Degrees of Freedom (DOF) VR system for both existing
mobile and PC operated VR. The aim is, to exploit the existing
IoRL architecture to provide a safer, wireless, high speed, less
laborious, more immersive and improved VR experience with
broader application
Wearable Communications in 5G: Challenges and Enabling Technologies
As wearable devices become more ingrained in our daily lives, traditional
communication networks primarily designed for human being-oriented applications
are facing tremendous challenges. The upcoming 5G wireless system aims to
support unprecedented high capacity, low latency, and massive connectivity. In
this article, we evaluate key challenges in wearable communications. A
cloud/edge communication architecture that integrates the cloud radio access
network, software defined network, device to device communications, and
cloud/edge technologies is presented. Computation offloading enabled by this
multi-layer communications architecture can offload computation-excessive and
latency-stringent applications to nearby devices through device to device
communications or to nearby edge nodes through cellular or other wireless
technologies. Critical issues faced by wearable communications such as short
battery life, limited computing capability, and stringent latency can be
greatly alleviated by this cloud/edge architecture. Together with the presented
architecture, current transmission and networking technologies, including
non-orthogonal multiple access, mobile edge computing, and energy harvesting,
can greatly enhance the performance of wearable communication in terms of
spectral efficiency, energy efficiency, latency, and connectivity.Comment: This work has been accepted by IEEE Vehicular Technology Magazin
System architecture and deployment scenarios for SESAME: small cEllS coordinAtion for Multi-tenancy and Edge services
The surge of the Internet traffic with exabytes of data flowing over operators’ mobile networks has created the need to rethink the paradigms behind the design of the mobile network architecture. The inadequacy of the 4G UMTS Long term Evolution (LTE) and even of its advanced version LTE-A is evident, considering that the traffic will be extremely heterogeneous in the near future and ranging from 4K resolution TV to machine-type communications. To keep up with these changes, academia, industries and EU institutions have now engaged in the quest for new 5G technology. In this paper we present the innovative system design, concepts and visions developed by the 5G PPP H2020 project SESAME (Small cEllS coordinAtion for Multi-tenancy and Edge services). The innovation of SESAME is manifold: i) combine the key 5G small cells with cloud technology, ii) promote and develop the concept of Small Cells-as-a-Service (SCaaS), iii) bring computing and storage power at the mobile network edge through the development of non-x86 ARM technology enabled micro-servers, and iv) address a large number of scenarios and use cases applying mobile edge computing
