Bridge the physical world and the cloud — reliably, at the edge.
Edge architecture, gateway integration and connectivity design that works with the equipment you already have, keeps running when the network does not, and can be updated safely in the field.
Built for the people accountable for the outcome.
Device, Edge & Connectivity is part of PEXIVA’s Connected Operations & IoT practice, which combines all six PEXIVA core capabilities.
Intended buyers
- VP Engineering and OT leaders
- Plant and facilities engineering managers
- Connected-product and device leaders
- Infrastructure and network architects
What this solves.
Equipment that speaks many languages
Controllers, meters and building systems use different protocols and data formats, often undocumented.
Sites with unreliable networks
Remote, mobile or congested environments lose data unless the edge buffers and forwards it.
Devices nobody can update
Fleets ship without a safe over-the-air update path, so vulnerabilities and bugs stay in the field.
Connectivity chosen on habit
Cellular, Wi-Fi, LPWAN and wired options are not compared on coverage, power, cost and data volume.
Device, Edge & Connectivity — what’s included.
- PEXIVA-deliveredPEXIVA practitioners own and perform the work.
- PEXIVA-ledPEXIVA owns architecture, governance and delivery, with specialist contributors.
- Partner-enabledA qualified specialist delivers a defined work package under PEXIVA program governance.
Edge architecture
Placement of processing, storage and decision logic between device, gateway and cloud.
Device and gateway integration
Connecting existing equipment through gateways using standard industrial and building protocols.
Protocol translation
Normalizing Modbus, OPC UA, BACnet, MQTT and vendor formats into a common data model.
Offline and intermittent-connectivity design
Store-and-forward, local buffering and safe degraded modes.
Local processing and buffering
Filtering, aggregation and edge inference to reduce bandwidth and latency.
Device onboarding
Zero-touch or low-touch provisioning with unique identity per device.
OTA update architecture
Signed, staged and reversible software and configuration updates.
Connectivity selection
Comparison of wired, Wi-Fi, cellular, LPWAN and satellite options for each site profile.
Embedded and hardware engineering
Custom device design, PCB, sensor engineering and embedded firmware.
PEXIVA leads solution architecture, cloud, data, applications, security and program delivery. Device engineering, controls, installation and local field services may be delivered with qualified specialist partners based on project requirements and geography.
What you receive.
- Edge reference architecture
- Protocol and data-model mapping
- Gateway deployment pattern
- Onboarding and identity workflow
- OTA update design
- Connectivity options analysis
- Device and gateway specification (with partners)
From equipment to a governed data stream
Inventory
Catalogue equipment, protocols, network paths and constraints with your OT team.
Pattern
Choose the edge pattern — thin gateway, edge analytics or local control support.
Prove
Validate data access, buffering and failover on representative equipment.
Template
Package the pattern so additional sites can be onboarded consistently.
Where this is typically applied.
Illustrative use cases — not descriptions of specific client deployments.
Reading PLC and historian data without changing control logic
Read-only data paths agreed with controls engineers.
Remote or mobile assets on cellular
Bandwidth-aware telemetry with local buffering.
Building systems integration
BACnet and Modbus data from HVAC, lighting and meters into one model.
Edge inference
Running a trained anomaly model locally where latency or bandwidth matters.
Designed in, not bolted on.
- Each device and gateway receives a unique identity; no shared credentials.
- Edge devices sit in segmented network zones with least-privilege outbound connections.
- Updates are signed, staged and can be rolled back.
- Physical access and tamper risk are considered for exposed sites.
Engagement models
Common ways to start or continue this work:
- Architecture and Security Review
- Fixed-scope PoC
- Production Implementation
- PEXIVA-led partner consortium
