5G

5G is the next generation of mobile broadband that will eventually replace existing 3G or 4G LTE networks. 5G stands for Fifth Generation Wireless technology and is used for voice and data. 5G technology brings new capabilities that will create opportunities for people, businesses and society.

5G will dramatically improve our network connection with a faster, more stable, more secure connection and new services and experiences. We will benefit from better performance, more efficient capabilities and vastly increased capacity with 5G. Data rates are set to be 100 times faster, supporting instant access to services and applications.

Network latency will be significantly reduced to 1-10ms and new network slicing technology will make it possible to dedicate a unique part of a 5G service provider network to a service.

5G also presents an opportunity for operators to tap into new revenue streams emerging from the digitalization of industries. According to Ericsson’s “Guide to capturing the 5G-IoT business potential”, service providers can benefit from up to USD 619 billion market opportunity globally in 2026 from new use cases, new services new business models and new eco-system due to 5G network capabilities.

Through its research RedZinc has been at the forefront of 4G and 5G network technologies focused on User Experience, Performance and Economics. RedZinc evolved a technology for enabling QoS in packet networks, an ability to prioritise and define quality levels of communications across the Public Internet. VELOX™ delivers the wholesale new order for IP carriers.

Projects

RedZinc has long been interested in network slicing and its role in maximizing network resource sharing, optimizing network requirements from diverse business sectors and upgrading network capabilities and quarantees in Quality of Service (QoS) and/or Quality of Experience (QoE). 5G network slicing could be considered as one of the most important innovations in communications of the decade due to its impact on how network operators can make money from their network using Software Defined Networks (SDN) and Network Function Virtualisation (NFV) for flexibility and lowered costs.

Using the SliceNet multi-domain framework, design principles and techniques such as orchestration, management plane, control plane and QoE management, slicing containers and modules, RedZinc has developed a mobile telemedicine platform. Two mobile telemedicine products have been developed on this platform, BlueEye Handsfree headset for video streaming professional-to-professional and BlueEye Direct Video for two-way video streaming professional-to-patient healthcare. These applications can be used on 4G networks today and on the forthcoming 5G networks with slicing and QoS features in the future.

RedZinc set up and managed the pan-European multi-domain 5G orchestration testbed including network operators Orange France, Telenor, Telecom Italia, Telefonica Spain and Deutsche Telekom, for the purpose of evaluating slice management in the context of 5G. The initiative was to enable a unified European 5G infrastructure service market to integrate multiple operators and technologies.

The SAFE experiment was a FED4FIRE project conducted by the University of Malaga with RedZinc to study video performance in a scenario where immersive wearable mobile live-streamed video assists first responders in public safety applications such as ambulance paramedic attending to a patient. The motivation behind the experiment was to find a life-saving application used over mobile networks.

Clinical decisions made pre-hospital or at the scene of a medical emergency can be crucial and potentially life-saving. Live streamed video from a first responder to an emergency department in the hospital or a first responder command center can help make rapid decisions (e.g. quick delivery of clot busting drugs).

As part of the 5G Worcester project, RedZinc deployed 4K cameras in the Bosch factory and evaluated performance on Huawei and Ericsson 5G Networks. The 4K camera were integrated with the BlueEye webRTC platform located in the UK. The target application for the cameras was a robot manufacturing cell

RedZinc worked with the Ghent University Hospital and IMEC, an international research & development and innovation hub, in order to develop adaptive video methods suitable for 5G wireless networks. This work integrated and validated a video codec adaption system based on network parameters describing the condition of the uplink air interface and other relevant parameters.

Adaptive bit rate, frame rate and frame size were managed according to the variable radio network needs. The results were implemented in the 5G lab in IMEC in the University of Ghent and showcased at the Ghent University Hospital (UZGent).

Applications

Bosch wanted to explore 4K cameras on a 5G network as part of a campaign to enhance robotics and automation in their factories using 5G advantages of lower latency and high speeds. The application was to monitor robotic manufacturing processes of their boiler equipment. Bosch chose RedZinc to provide the 4K cameras integrated with their BlueEye Video Platform and to test this on the Worcestershire 5G testbed. RedZinc was selected due to its leadership in 5G network video applications.

RedZinc stress tested the BlueEye Video Platform with 4K camera on a 5G network at Malvern Hills Science Park. The stress testing involved loading the 5G network with a high volume of traffic and validating image performance with high definition 4K cameras. This was to evaluate if the network could support the high uplink bandwidth rates needed for 4K video. The work carried out by RedZinc confirmed that the 5G network was able to support the high uplink rates needed for 4K video quality as might be used by 4K wearable video and 4K industrial monitoring. The positive results opens up a whole range of opportunities in high definition monitoring on 5G networks for industry.

Network Technologies

Orchestration

Orchestrators coordinate multiple controllers of multiple resource types and provision other resources such as virtual machines. RedZinc has developed a type of orchestrator called a Virtual Path Slice or VELOX™ as part of the EuQoS project. VELOX™ coordinates resources using available network controllers such as routers, SDN controllers, RAN EPC and others to generate an end-to-end path across the network, specific for network Quality of Service.

VELOX™ uses existing software and hardware to provide a simplified dynamic way to alter network priorities. These priorities are driven by the user who will have different needs for different applications. For example, some video stream needs very high bandwidth for instance in High Definition (HD) and some data stream like text messages will only require a small amount of bandwidth.

RedZinc used VELOX™ to operate new SDN technologies and test scaling in the CityFlow project. The goal of the project was to simulate a city of the population of Brussels with realistic network requirements based on the time of day and expected busy hours.

QoS

Software Defined Networks (SDN), Network Function Virtualization (NFV) and OpenFlow are techniques that provide high flexibility and can cut costs in packet data networks. Virtual Path Slicing (VPS) is a method that has evolved from studies on how to implement end to end QoS in packet networks.
RedZinc has implemented a VPS engine called VELOX™ that can steer traffic on the edge of the network based on the request of the application and coordinate this traffic steering with other autonomous systems. RedZinc’s solution VELOX™ enables owners of Internet infrastructure to build zettanet infrastructure which empowers web portals and their users to put higher value traffic in priority flows.

VELOX™ Improves User Experience, Performance, Economics.
In traditional 3GPP EPC the VPS engine can provide services to the application layer and invoke them using the Rx interface in the Policy Charging Rules Function (PCRF) of the EPC where differentiated QoS Class Identifier can be used for different service levels.
