Sectors

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.

Connect and MSN renewal · FTNx-style operational bearers · CBTC and ETCS convergence · Phased cutover on live estates

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.

SCADA and RTU transport · IP-CCTV estates · TETRA to ESN transitions · Deterministic MPLS-TP design

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.

BSH-fed cluster architecture · Street-furniture laterals · Reach and channel planning · Concession-grade documentation

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.

Open and disaggregated line systems · SDH to OTN and packet migration · OSNR and GSNR engineering · Multi-vendor interoperability

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.

Greenfield PON design · Design audit and QA · Overbuild due diligence · As-built data quality
§02
Distinction

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.

Operational networks

Safety-of-life estates that keep trains moving: radio, CCTV, SCADA and signalling comms on resilient bearers with engineered margins and formal assurance.

LU Connect · FTNx · GSM-R to FRMCS
Passenger connectivity

Commercial neutral-host coverage for phones and devices: 4G and 5G small cells, DAS and high-count fibre backhaul under concession commercial models.
