5G, Live Webinar -

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...

Live Webinar: 9th November 2021 | 10-11am (UK Time) Join Les Granfield on Tuesday 9th November (10-11am UK Time) for this free training webinar The Digital Railway supported by FRMCS Register here. 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...

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...
