continued to maintain the GSM-R (GSM for railways)

continued to work on the incorporation of Internet Protocol
into the core network and interface specifications, updating
our TS on the use of Session Initiation Protocol (SIP). By the
end of 2016, we had completed a stable draft of a new TS on

We completed a study into the feasibility of operating C-ITS

taking account of further feedback from the ITS community,
was published in September.
