In deploying 5G, operators are committing to a significant investment cycle. It therefore follows that they expect a return on that investment within a reasonable timeframe. The question is how! Fundamentally, in terms of both the radio on the overall infrastructure architecture, 5G works in a similar way to 4G. However, the implementation is very different, and this gives 5G several key advantages over 4G in terms of supporting both the existing broadband business model, and industry-specific use cases. The advantages are realised across the entire 5G system, but in particular, the 5G New Radio (NR) air interface is where...

As part of the study item FS_SMARTER, ‘Study on Stage 1 for New Services and Markets Technology Enablers’, 3GPP examined the market segments whose needs should be addressed by a 5G mobile communication system. TR 22.891 identified over 70 use cases, and collected those use cases into the five categories shown in the diagram. The first four categories are based on common requirements in support of a vertical service or market: eMBB (Enhanced Mobile Broadband): Human-oriented access to multimedia content, services and data. The category includes hotspots, characterised by high user density, very high capacity and low mobility, and widearea coverage, characterised...

Rail networks increasingly depend on efficient and reliable communications networks, the demand for up-to-date technical skills for those involved in maintaining and developing transport communications systems continues to grow, investing in the right training to develop up-to-date skills is vital. Designed and delivered by our industry leading subject matter experts, our collection of live and tutor supported self-study courses cover current transport communication technologies including GSM-R and GSM-R support for ERTMS/ETCS, including future developments that will come with FRMCS. As well as in-depth investigation of the technologies each course also considers operational procedures and practices, network performance and radio planning....

A cellular radio communications system is subject to a number of threats, which are outlined in the diagram below..The motivations for attacks against cellular networks typically fall into one of the following categories: attempts at unauthorised network access to get free services attempts at ‘grabbing’ user identities to make clones attempts at eavesdropping on network traffic to gain unauthorised access to information attempts at tracking users by eavesdropping on signalling traffic The vulnerability of cellular systems to these threats is based mainly on the fact that they employ radio-based user connections.Typically, the most vulnerable parts of the cellular system are...

We are delighted to announce a partnership that will see the delegates at FutureNet Asia in October gain free access to a Wray Castle virtual telecoms training course focusing on 5G SBA (Service based architecture), which is an important theme at the event. 5G SBA Virtualizing the Core:  13th October @ 4pm-5.30pm (SGT, UTC+8) 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...
