How to Set Up Internet and Wi-Fi on a Construction Site
A new job site usually gets a trailer, a portable toilet and a fence on day one, and internet some time after the first week of crews tethering laptops to their phones. That gap costs real money: delayed drawings, missed emails from the office, safety forms that never get submitted and project managers driving back and forth. This guide shows how construction companies in BC can plan reliable, secure internet and Wi-Fi for every site, from a single house build to a multi-year project.
Quick plan
- Decide connection type early: wired service, fixed wireless, cellular or satellite, based on location and project length.
- Use business-grade equipment: a firewall, a weatherproof access point and a backup connection.
- Keep the site network separate from guests and subcontractors, and lock down company devices.
- Pack it into a standard “site kit” so every new site is set up the same way in hours, not weeks.
Step 1: Choose the right connection for the site
| Option | Best for | Watch out for |
|---|---|---|
| Wired (cable or fibre) | Long projects in built-up areas | Installation lead times can be weeks, so order early |
| Fixed wireless | Medium-length projects where wired service is slow to arrive | Needs line of sight to a provider tower |
| Cellular (LTE/5G router) | Fast setup, short projects and as a backup | Data caps and signal strength vary by location |
| Satellite | Remote and rural sites | Equipment placement and weather, so plan mounting carefully |
Tip: combine two types, for example wired plus cellular, with a router that switches over automatically. Then a cut cable from an excavator does not take the site offline.
Step 2: Build a standard “site kit”
- ☐ Business-grade router or firewall with automatic failover
- ☐ Weatherproof or ruggedized Wi-Fi access point for the trailer and yard
- ☐ Small battery backup (UPS) so short power cuts do not reboot everything
- ☐ Lockable enclosure or cabinet for the equipment
- ☐ Pre-configured settings, so it works the moment it is plugged in
- ☐ A printed one-page sheet: who to call for support and how to restart the equipment
Our Wi-Fi solutions and firewall management services prepare and manage these kits for you.
Step 3: Keep the site network secure
- Separate networks: one for company devices, one guest network for subcontractors and visitors. Guests should never reach your company laptops or file storage.
- No default passwords on routers or access points, and a strong Wi-Fi password changed when crews change.
- Managed devices: tablets and laptops that can be located, locked or wiped if stolen from the trailer or a truck.
- Files in the cloud, not on the site laptop. Drawings and photos in SharePoint and OneDrive stay safe even if the device does not.
Step 4: Make sure crews use the current drawings
Good internet is only useful if the right files reach the field. Set up one shared project folder per job, with clear folders for current drawings, superseded drawings, RFIs and photos. Tablets sync automatically, so supervisors always open the latest revision, and version history lets you recover anything overwritten by mistake.
Step 5: Plan the shutdown too
When the project ends, cancel or move the service on time, collect the equipment, wipe any stored settings and archive the project folder with a reliable cloud backup, because warranty and dispute questions can come years after handover.
Frequently asked questions
How fast does a job site connection need to be?
For email, video calls, drawings and photo uploads, a stable connection matters more than raw speed. Plan for comfortable upload speeds if crews upload many photos or large files.
Can we just use our phones as hotspots?
For a day or two, yes. For longer, phone hotspots are unreliable, drain batteries and leave no central security or support.
Who supports the site network when something breaks?
With a managed setup, your IT provider can see and fix most issues remotely, and send someone on-site when needed. See our on-site IT support.
