Where we work.
Five buyer environments, each with its own constraints, assurance regime and vocabulary.
Rail & metro operational telecoms
The bearer networks that keep trains moving safely: renewal and migration of live operational estates such as LU Connect, and the convergence of CBTC, ETCS, CCTV and SCADA onto shared IP bearers.
The LU Connect renewal under Hitachi Rail and the LU Connect video WAN under Thales.
Mission-critical & OT networks
Operational technology that carries life-safety and control traffic: SCADA, PA/VA, IP-CCTV, help points, TETRA today and FRMCS and ESN tomorrow, engineered for deterministic behaviour.
Live CCTV, SCADA and operational comms carried through successive LU Connect migrations in continuous service.
Neutral-host & concession fibre
High-count fibre and DWDM bearers feeding 5G small cells on street assets under long concessions, engineered to reach budgets from Base Station Hotels over re-used duct.
TfL Connected London, Streetscape workstream, for Boldyn Networks and Telent.
Optical transport & carrier metro
DWDM, OTN and SDH transport for carriers and large estates, including migration from legacy TDM to packet and coherent pluggables from 400ZR to 800ZR.
Staged migration across the LU Connect SDH estate and close-out of the Elizabeth line C660 backbone.
Altnets & FTTP
Design, audit and rationalisation for fibre builders as the market moves from land grab to optimisation: cost-per-premise discipline, design QA and trustworthy as-built data.
Two networks, two disciplines.
The clearest test of a rail-telecoms specialist is whether they separate operational networks and passenger connectivity. We design for both, and we never blur them.
The distinction between operational networks and passenger connectivity.
Safety-of-life estates that keep trains moving: radio, CCTV, SCADA and signalling comms on resilient bearers with engineered margins and formal assurance.
Commercial neutral-host coverage for phones and devices: 4G and 5G small cells, DAS and high-count fibre backhaul under concession commercial models.
Bring us in at survey, not at rework.
A 30-minute technical call to pressure-test route, reach and margins before anything is committed to civils.
