One vehicle. Many markets.
The same connected service behaves differently across operators, roaming partners, technologies and local market conditions.
Connectivity for the software-defined vehicle.
From connectivity architecture to cellular & satellite integration, validation and rollout.

The challenge
Where automotive connectivity gets difficult.
Connectivity problems rarely stop at supplier boundaries. Neither do we.
Gaps appear between variants.
Hardware, firmware and vehicle configurations can behave differently once they meet real networks and roaming environments.
Ownership is fragmented.
OEMs, Tier 1s, connectivity providers, MNOs and backend teams may each own only one part of the incident.
Failures appear late.
Issues can surface only after a firmware change, market launch, network update or a specific roaming scenario.
One partner. Complete lifecycle.
From the first architecture decision to stable operation.
A consistent engineering model prevents handover gaps and keeps technical decisions connected across teams and markets.

Define
Connectivity architecture, TCU requirements and market constraints.
Clear technical direction
2
Integrate
Backend, provisioning, infotainment services, and emergency-service interfaces.
Working end-to-end chain
3
Validate
Real networks, roaming, firmware, diagnostics, remote testing and local markets.
Market-ready connectivity
4
Roll out
Cellular & satellite rollout, multi-market activation, and ongoing support.
Reliable global service
Automotive programs we support.
Start with a defined work package or bring us into a complex cross-supplier program. The scope follows the technical problem.
Launch a connected platform
Define connectivity architecture, TCU and eSIM requirements, supplier interfaces and target-market readiness.
↗Move to SGP.32
Translate the new provisioning model into device, platform, process, operational and validation requirements.
↗Implement eCall / NG-eCall
Coordinate and validate the chain across vehicle, modem, network, IMS/VoLTE and emergency-service interfaces.
↗Enter new markets
Validate local networks, roaming, activation, service routing and market-specific edge cases before launch.
↗Integrate satellite connectivity
Combine cellular and satellite connectivity to maintain service beyond terrestrial network coverage.

Featured success story · ValidateProven in automotive connectivity
Global validation for a premium automotive OEM.
Horizon Connect established remote access, real-network testing and diagnostic workflows so engineering teams could reproduce and analyse connectivity issues without being physically present at the test location.
40%less test setup time
15+networks and markets validated
30%faster issue reproduction
WHY HORIZON CONNECT
Automotive, telecom, and validation expertise in one team.
We combine product engineering with network-domain experience to manage the dependencies across systems, suppliers and markets.
Automotive and telecom expertise
We understand both the vehicle and the mobile-network side of the connectivity stack.
End-to-end ownership
We investigate the complete service path instead of stopping at individual supplier boundaries.
Direct MNO Access
We work with local operators and technical teams to resolve network, roaming and provisioning issues closer to the source.
Lifecycle experience
We look beyond SOP and help build connectivity that remains manageable across markets, releases and vehicle generations.
