Business Drivers For Migrating To The Cloud
Businesses and individuals may elect to migrate some or all of their applications and systems to the cloud for a number of reasons, among the most frequently quoted are: Competitive AdvantageBusinesses judge that moving to cloud-based services will provide them with a competitive advantage over other companies. There may be many ways in which an advantage may be quantified but they could include faster or more flexible responses to changing market conditions and the ability to roll new products and services out more quickly than would have been possible with a legacy IT architecture. The three following drivers can also...

5G Spectrum
Background 5G is set to change the picture significantly in terms of spectrum allocation and use, and in this article, we aim to provide more clarity in terms of the many issues related to the licensing, standardisation / harmonisation, and use of spectrum as we head towards the 5G era. Spectrum is highly sought after, primarily because it allows an operator to increase capacity on the network efficiently. The additional spectrum can be added to existing base stations which reduces the number of new base stations needed. This makes spectrum highly valuable, hence regulators will charge a fee for licensed...

Webinar: 5G Network Slicing (28th Feb)
Recorded: 28th February 2022 The 5G standards support many different use cases and deployment scenarios using a wide range of techniques and design principles. In turn, these support diverse network capabilities and performance centred on attributes such as data rates, capacity, latency, energy use, user density, reliability, and security. In order to map these capabilities to the use cases in a way that maximises overall efficiency and cost effectiveness, the concept of the “Network Slice” has been introduced. It allows for a range of “capability sets” or “virtual networks” (supporting different use cases, deployment scenarios, or even different customers) to...

Webinar: Network Function Virtualization (23rd Nov)
Recorded: 23rd November 2021 Cloud computing has revolutionized the way IT Services are deployed and used, allowing major improvements in flexibility, availability, and simplification, whilst offering opportunities to speed up time to deploy new services and realise cost savings. The core technology behind Cloud based services is virtualization; could this be leveraged to provide the same benefits to the communications market? Many communications services are of course based on software applications, which do lend themselves to virtualization and thus cloud deployment. However, communications are also dependent on connectivity services – can virtualization of these services be modelled and managed in a...
Evolution of LTE Towards 5G
In the original version of LTE (3GPP R8), a UE only communicated with a single eNB, by means of a single cell. LTE-A (R10) introduced CA (Carrier ggregation), in which a UE supports a higher data rate by communicating with multiple cells on multiple carrier frequencies. All the cells are controlled by a single eNB. There is one PCell (Primary Cell), which carries traffic and RRC signalling messages, and optionally one or more SCells (Secondary Cells), which carry traffic alone. The PCell supports both UL and DL, but the SCells can be DL-only.DC (Dual Connectivity) was introduced in 3GPP R12. When using...
Webinar: The Digital Railway supported by FRMCS (9th Nov)
Webinar Recorded: 9th November 2021 FRMCS is the Future Railway Mobile Communications System and is an integral part of the digital railway. The term digital railway was coined when GSM-R was deployed on the European networks to provide train to trackside communications. GSM-R is a digital radio system that has been used successfully over the past 20 years - over 100,000 Km of lines have been covered with more to come in the coming years. However, GSM-R has a limited lifespan with equipment vendors stating that they no longer wish to support GSM-R beyond 2030. GSM-R, as well as providing...
Architectural Options for 5G
Many of the benefits of 5G, such as low user plane latency, high data rate and support of high radio frequencies, can be achieved simply by transmitting data over the 5G New Radio. Furthermore, there are market pressures on network operators for an early roll-out of 5G networks in which those benefits are delivered to the user. To reflect these issues, 5G is designed to support an evolutionary roll-out in which operators can gradually introduce the capabilities of 5G into their networks, without the immediate need for wide-area 5G coverage. This is achieved using a number of different architectural options,...
Evolutionary Rollout of 5G
Many of the benefits of 5G, such as low user plane latency, high data rate and support of high radio frequencies, can be achieved simply by transmitting data over the 5G New Radio. Furthermore, there are market pressures on network operators for an early roll-out of 5G networks in which those benefits are delivered to the user. To reflect these issues, the 5G New Radio is designed to support an evolutionary roll-out in which it inter-operates closely with LTE. The resulting architecture is closely based on the architecture for DC in LTE.In the first phase, the mobile continues to communicate...
Webinar Recording: 5G Service Based Architecture (SBA) Virtualizing the Core
Webinar Recorded: 13th October 2021 The Service Based Architecture (SBA), standardised as part of 5G, represents a paradigm shift in the way the telecoms core network is planned, deployed, and operated. Using virtualisation principles, the SBA provides a more flexible, efficient, and capable set of features – provided by the different Network Functions in the form of NF “Services”. SBA techniques can also be applied to 4G, and if adopted early, would enable a smooth transition to the 5G Core.This talk examines the principles of the SBA, before looking in more detail at the architecture, network functions, protocols, and operation. We also...
Webinar Recording: 5G New Radio
Webinar Recorded: 12th October 2021 Delivering ever-increasing data volumes to a growing customer base who are willing to accept mobile and nomadic broadband services places enormous strain on telecoms operators in terms of capacity requirements and network densification. New broadcast-based services and business models, as well as connected innovation and IoT, add to the challenges. A range of measures can be used to ease the pressure, and many have been the subject of ongoing development as part of the 4G LTE Radio. The introduction of 5G New Radio, however, has provided an opportunity to take a fresh look, optimise techniques, and,...
