Choosing Jobsite Internet: LTE, 5G, Starlink or Fixed Fiber

A practical comparison of cellular, 5G, satellite and wired options for jobsite connectivity, with questions to ask before you commit to a contract.

Every project superintendent eventually asks the same question: how do we get reliable internet to a site that has no building, no utilities, and sometimes no cell tower nearby? There is no single right answer. The best option depends on how long the project runs, how many people and devices rely on it, and what happens to the schedule when the connection drops.

This guide walks through the main choices and the questions that should drive the decision.

Start with what the site actually needs

Before comparing providers, list what will run on the connection. A trailer with a few laptops syncing plans is a very different load from a site with security cameras, drone uploads, telematics, a time clock, and a dozen tablets pulling model files. Note whether any of it is time-critical, such as access control, safety systems, or concrete pour coordination.

Also note the duration. A three-week repair job and a two-year build justify different investments.

The main options

Cellular LTE and 5G routers

A rugged cellular router with an external antenna is the workhorse for most jobsites. It is fast to deploy and can move with the trailer. Performance depends heavily on local coverage and tower congestion, so test before you commit. Check signal at the actual trailer location, not at the gate. Plans differ in data limits, throttling after a threshold, and priority during congestion, so read the fine print on what happens when you use a lot of data.

Consider a dual-SIM router that can fail over between two carriers. Different carriers often have very different coverage on the same site.

Satellite internet

Low-earth-orbit satellite service can work where cellular is weak or absent, which describes many pipeline, remote energy, and rural projects. It needs a clear view of the sky, so tree lines, cranes, and structures matter when placing the dish. Weather and obstruction can affect performance. It also makes a useful second path alongside cellular rather than only a replacement.

Fixed wireless and wired service

If a utility or provider can bring fiber or cable to the site, it is usually the most stable and the most cost-effective per megabyte for long projects. The tradeoff is lead time. Installation can take weeks or months, so many contractors start with cellular and transition when the permanent service arrives.

Design for failure

Single connections fail. The question is whether the site can keep working when one does.

  • Use a router that supports automatic failover between two links.
  • Keep critical files available offline on field devices where practical.
  • Know which systems stop working when the connection drops and tell the crew.
  • Put the router and modem on a small battery backup so brief power loss does not require a truck roll.

Secure it from day one

A jobsite network often grows quickly and carelessly. Change the default router password, turn off remote administration from the open internet, and keep firmware updated. Use a separate network for guests and subcontractors, and keep cameras and other devices apart from the laptops that hold financial and project data. Where possible, use a VPN or secure access service so field devices reach company systems through a protected path.

Document who owns the equipment and what happens to it when the project ends. Routers returned to a shelf with the previous site's settings and passwords are a common and avoidable exposure.

Questions to ask before signing

  1. What is the actual coverage and speed at our specific location, tested on site?
  2. What happens after the data allowance is used?
  3. Can we move the service to the next project, and what does that cost?
  4. How quickly can we get a replacement device if one fails?
  5. Who monitors the connection and who do field staff call?

Getting help with deployment

Ironfield Cyber helps contractors and energy companies design repeatable jobsite connectivity kits, including routers, antennas, failover, and secure remote access, so each new project starts from a tested standard instead of a one-off scramble. If you are planning a new site or reworking an existing setup, we are glad to review the plan with you.
