Recorded: 28th April 2022 Network Function Virtualization (NFV) has capitalised on Cloud Computing to revolutionize the way Communications Services are deployed and used, using virtualized IT infrastructure, to generate major improvements in flexibility and availability, offering opportunities to reduce the time to deploy new services and realise cost savings. Multi-access Edge Computing (MEC; formerly Mobile Edge Computing) extends the NFV concept to deploy the virtualization resources at the network edge rather than in the core/public network – near to the users, thus enabling a range of additional benefits in terms of application performance, support for users, access to network information, data...

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...

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...

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...

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 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...

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,...

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 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 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,...

There is a lot of news in the press concerning the ‘digital railway’ as if this is a recent development.  In fact the digital railway came into being with the first operational implementation of GSM-R in 1999.  The International Union of Railways (UIC) describe GSM-R as ‘the bearer for the first Digital Railway Radio Communications System’.  GSM-R is a second generation (2G) digital radio system based on the commercial GSM mobile telephony system, but adapted for use on the railways.  It have been hugely successful across Europe, being used in over 20 countries across 100, 000 Km of tracks and...

A network slice is a virtual logical network, which runs on common underlying physical infrastructure, and whose capabilities are optimised for a particular use case. Examples might include slices serving a utility company, a VN operator or a factory remote control system, or a slice that is optimized for the delivery of streaming video. Different network slices are isolated from one another, notably in respect of data transport (so that congestion in one slice does not affect any of the others) and security (so that an attack on one slice does not affect any of the others). An individual UE attaches to one or more...

When planning a microwave link it is imperative to ensure there is sufficient clearance between the main bore of the radio signal and any obstacles along the radio path. There are various rules and guidelines defining what is meant by sufficient clearance - they may be set by a national spectrum management authority, in-house criteria, or recommended by a body such as the ITU-R. All of them, however, require the radio planner to apply the relevant k factor associated with the chosen clearance criteria and model. It is therefore paramount that the radio planner fully understands the function of the...
