Connectivity on Construction Sites: The Challenge of Temporary Internet Access
An industrial or construction site is, by definition, a temporary facility—lasting anywhere from a few weeks to several years, depending on the project. Internet connectivity requirements have changed dramatically in recent years: teams need to access BIM plans in real time, manage documents from the cloud, hold video conferences with the project owner, and remotely monitor construction site equipment.
However, construction sites generally lack pre-existing network infrastructure: no fiber, no ADSL, and sometimes not even a fixed power supply. Traditional solutions (sharing a smartphone connection, 4G USB dongles) are insufficient for intensive professional use.
Eziwan’s 4G connectivity for industrial sites meets this need with professional-grade equipment designed for:
- Deployment in less than 30 minutes without technical network expertise
- Industrial-grade reliability: rugged IP40 router, dual SIM with multi-carrier support
- Centralized management from the office: monitoring, configuration changes, and virtual relocation from one job site to another
Deployment in 30 Minutes: The Eziwan Plug & Play Method
The Eziwan 4G Construction Site Connectivity Kit is designed to be deployed by a construction site manager, without the need for an IT technician:
Step 1 — Receiving the Preconfigured Kit (Day 1) The Eziwan kit arrives ready to use: an M2M SIM card with APN and VPN already configured, a router registered in the Eziwan portal under your project name, and an illustrated 5-step installation guide.
Step 2 — Physical Installation (5–10 minutes) Mount the router in your equipment room (construction site meeting room, site manager’s office) on a flat surface or DIN rail. Screw the external antenna in place or unfold the magnetic mount and attach it to the window sill.
Step 3 — Power (2 minutes) Plug in the included 230V AC adapter (or a 12/24V DC power supply from the generator). The router will start up, and the LEDs will indicate the 4G connection and network availability.
Step 4 — Wi-Fi Setup (5 minutes) The router automatically broadcasts the "Eziwan_Chantier_XXXX" Wi-Fi network. Connect your work computers, tablets, and smartphones using the password printed on the router.
Step 5 — Corporate Network Access (automatic) The VPN automatically connects to your company’s network. Users can access internal servers, applications, and documents just as if they were in the office.
Multi-SIM, multi-carrier: guaranteed coverage throughout France
Mobile construction sites (pipeline installation, railroad work, road construction) operate in areas with widely varying levels of network coverage. Eziwan’s multi-carrier Dual SIM solution ensures connectivity no matter where you are:
| SIM Configuration | Benefits | Recommended Scenario |
|---|---|---|
| Single-carrier SIM | Simple, cost-effective | Fixed job sites in areas with good coverage |
| Eziwan multi-carrier SIM | Automatic national roaming | Mobile job sites throughout France |
| Dual SIM (2 carriers) | Maximum redundancy | Critical job sites, tunnels, border areas |
The Eziwan multi-carrier M2M SIM card uses permanent national roaming on Orange, SFR, Bouygues, and Free: the router automatically selects the carrier with the best signal, with no roaming charges and no manual configuration required.
Applications and Uses on Construction Sites: What 4G Enables
BIM Document Management and Construction Drawings: Real-time access to BIM models (Revit, ArchiCAD) and CAD drawings (AutoCAD) from the company’s server. Update drawings on the central server directly from a tablet on-site—no more outdated paper drawings.
Construction Management Software: SaaS applications such as Autodesk Build, Procore, or OPTEXim require a constant internet connection. Eziwan 4G ensures their availability throughout the construction project.
Video Conferencing: Teams, Zoom, or Webex meetings with the project owner, architect, or subcontractors from the construction site meeting room. A stable 4G connection at 5 Mbps is sufficient for HD video conferencing.
Monitoring of safety sensors: strain gauges, sound level meters, vibration sensors on adjacent buildings, and embankment monitoring—data is transmitted in real time to the engineering office via the Eziwan 4G router.
Remote Access to Machine Controllers: Remote maintenance of controllers installed in excavators, cranes, tunnel boring machines, or drilling rigs via Eziwan VPN, without the need for a manufacturer technician to travel to the site.
Cost Control and Construction Site Fleet Management
For construction companies managing multiple job sites simultaneously, the Eziwan cloud portal offers centralized fleet management:
Overview: All your job site routers on a single map, with real-time status indicators (connected, weak signal, data usage, alerts).
Virtual Move: When one job site ends and a new one begins, you "move" the router from one job site to another within the portal—the configuration updates automatically without having to reconfigure the physical router.
Shared Data Pool: Your entire fleet of construction sites shares a single overall data allowance. Sites in the active phase use more data, while those nearing completion use less. Automatic optimization with no additional overage charges per router.
Exceedance Alerts: Immediate notification if a project shows abnormal usage (data leak, user streaming), so you can take action before incurring additional costs.
Monthly Reports: Accurate billing by job site, project, and client—to pass on connectivity costs to your clients or track expenses by project.
Removal from the job site: Return to inventory and reassignment
Once the project is complete, the Eziwan router is just as easy to decommission as it is to deploy:
- Disconnect the router and the antenna (takes 5 minutes)
- Return the router to inventory or immediately reassign it to a new job site
- In the Eziwan portal, archive the completed project—the router is now unlinked from the project configuration and ready to be reassigned
- The M2M SIM remains active on the same pool plan or can be suspended if necessary
The Eziwan 4G router is designed for thousands of deployment/removal cycles—its industrial-grade durability ensures a service life of 7 to 10 years, even with heavy mobile use.
