4G radio coverage in London Underground’s Tunnels – London & SE Section
25 Feb 2021 6:00 PM - 8:00 PM
Section: London & South East section (londonse@irse.org)
The London & South East section bring you another online presentation on 25 February 2021.

Join us this February for a lecture by Haider Gillani, Dr Dimitris Kaltakis & Robert Frith on 4G radio infrastructure on the Jubilee Line.


The presentation will cover Transport for London’s recently deployed 4G/LTE capable neutral host radio infrastructure on the Jubilee line; outlining some key facts regarding the build while presenting the architecture, challenges and performance statistics. It will also discuss the current status of cellular technologies and Standards (5G-NR/4G-LTE) and the use of these for mission & safety critical services/applications such as FRMCS which will be the successor to GSM-R. Lastly, it will show how Signalling renewal programmes could utilise such critical services and take advantage of a 4G/5G capable neutral host infrastructure.

The presentation will be given by:
