Construction jobsite connectivity options in order of reliability and cost: (1) Business fixed wireless from a local ISP — best for long-term jobsites in coverage areas; (2) Starlink Business — best for remote sites without fixed wireless coverage; (3) Cellular bonding devices (Cradlepoint, Pepwave) aggregating multiple carriers — best for sites with decent cellular coverage; (4) Single carrier hotspots — adequate for small teams with light usage. All options should be paired with a managed router for security and traffic control.
Why Jobsite Connectivity Is a Business-Critical IT Problem
A decade ago, field crews worked with printed plans and paper forms. Today, Procore, Autodesk Build, and project video systems require reliable internet — and when connectivity fails, work stalls. Submittals can't be uploaded, RFIs can't be responded to, inspection photos can't be filed, and superintendents can't get the drawings they need.
The cost of a connectivity failure on a large jobsite — delays in approvals, inability to coordinate with the office, field crews standing around waiting for drawings — quickly exceeds the cost of any connectivity solution. Treating jobsite internet as a $30 hotspot problem is a false economy.
Option 1: Fixed Wireless Internet (Best for Long-Term Sites)
Fixed wireless internet uses a directional antenna mounted on the job trailer pointing at a wireless tower — similar to cable internet but without running cable. When available:
- Speeds: 50–500Mbps download depending on distance and provider
- Latency: 5–30ms — good enough for video calls and VoIP
- Cost: $150–400/month for business service
- Setup time: 1–2 weeks for installation and provisioning
- Best for: Jobsites lasting 3+ months in suburban or semi-rural areas
- Limitation: Requires ISP coverage in the area — not available in all locations
Option 2: Starlink Business (Best for Remote Sites)
Starlink Business provides satellite internet from SpaceX's low-earth orbit constellation. Unlike traditional satellite internet, latency is low enough for video calls:
- Speeds: 50–200Mbps download, highly variable
- Latency: 20–60ms — usable for video calls and VoIP
- Cost: $250/month service + $500 hardware (one-time)
- Setup time: Order online, self-install in under an hour
- Best for: Remote sites with poor or no cellular coverage
- Limitation: Performance degrades with obstructions (trees, buildings blocking sky view)
Option 3: Cellular Bonding (Best for Sites With Good Coverage)
Cellular bonding devices (Cradlepoint, Pepwave, Digi) use multiple cellular SIM cards simultaneously, combining their bandwidth and providing automatic failover if one carrier loses signal:
- Speeds: 100–400Mbps aggregate across 2–4 SIM cards when cellular coverage is strong
- Latency: 20–60ms on 4G/LTE; 5–30ms on 5G where available
- Cost: $200–600/month for multi-carrier data plans + $400–1,200 device cost
- Setup time: Same-day deployment if you have the device
- Best for: Sites with strong coverage from multiple carriers (urban and suburban)
- Limitation: Performance is entirely dependent on carrier coverage — fails in dead zones
The Job Trailer Network Setup
Once you have internet, the network inside the job trailer needs a managed router and switch:
- Managed router: Allows VLAN segmentation, bandwidth management, and remote monitoring. Consumer routers (Netgear, TP-Link consumer) are not appropriate for business use — they lack management features and are difficult to troubleshoot remotely.
- VLAN segmentation: Separate networks for: office equipment (laptops, printers), security cameras (if networked), guest/visitor Wi-Fi, and any connected tools or equipment
- Wi-Fi coverage: Job trailers often need multiple access points for coverage. Consider outdoor-rated access points if coverage needs to extend to a yard or parking area.
- Firewall and VPN: All traffic from the jobsite to the main office (ERP access, file sharing) should go over an encrypted VPN tunnel — not over the public internet
When to Call IT vs. When to Self-Manage
Small firms often manage jobsite connectivity themselves. The breakdown of when to involve your IT provider:
- Self-manage: Single hotspot for a small crew using cloud apps, where failure is annoying but not operationally critical
- Involve IT: Any site with 5+ connected users, VPN requirements for ERP access, security cameras, or business-critical applications where downtime costs money
- Involve IT: Any site where you're transmitting project documents that include security system layouts, access control configurations, or sensitive owner information
A construction IT provider should have a pre-configured jobsite network kit that can be deployed in a day — router, managed switch, and access points pre-configured for your firm's security requirements.
Frequently Asked Questions
How much data does a construction jobsite typically use per month?
A job trailer with 5–10 users actively using Procore, email, and video calls typically uses 100–300GB per month. Sites with video surveillance cameras streaming to the cloud use significantly more — a single 4K camera can consume 300GB/month. Plan data plans around your actual usage pattern.
Can I use a consumer Starlink residential plan on a jobsite?
Technically yes, but the residential plan has lower priority than Business during congestion and doesn't include the roaming portability that Business provides. For business use, the Business plan is recommended for both performance and terms-of-service compliance.
What security risks exist on a jobsite network?
Jobsite networks are often poorly secured compared to office environments. Risks include: unmanaged devices connecting to shared networks, visitors with network access, and weak Wi-Fi passwords shared broadly. Minimum security: WPA3 encryption, separate guest network, VPN for ERP access, and device management for company-owned tablets.
