Comparison

Dedicated internet vs broadband for business

Compare the capacity and service levels actually committed to your site with the broadband offer available at the same address. Fiber can carry either kind of service. The useful decision turns on required performance, failure tolerance, installation work, and the written contract.

What dedicated internet access actually is

A dedicated offer should specify the capacity committed to your site and the boundaries of the supplier’s service commitment. Ask the supplier to identify the access technology, the handoff at your premises, the committed rate, and the service-level schedule. A product name alone does not answer those questions.

What business broadband actually is

Broadband offers can use cable, DSL, or shared fiber access. The service may share network capacity with other users, but speeds, repair terms, installation dates, and prices vary by supplier and address. Compare those written terms against the dedicated offer; do not assume the broadband quote is automatically cheaper or quicker to install.

When dedicated internet is the right call

Consider DIA when a site needs a specific committed rate or service-level commitment for its work. Estimate the impact of a connection failure, then compare the quoted remedy and repair process with that impact. Confirm availability and installation requirements at the exact suite address before treating a proposed circuit as an option.

When broadband is the sensible primary

Broadband can be a sensible primary connection when its quoted performance and repair terms meet the site’s needs. Assess each location separately: an office and a revenue-critical site may need different commitments. Document the reason for the choice, including any backup path, so the next renewal can be judged against the same requirements.

Shared fiber is not dedicated internet

Passive optical networks can share an access medium among multiple customers. That means “fiber” alone does not establish whether a quoted service has dedicated capacity. Ask whether the rate is committed to your site, where that commitment begins and ends, and which service-level terms apply to this offer. Keep the answers alongside the quote so the products are compared on the same basis.

The medium comparison (fiber plant vs cable plant) is a different decision. See fiber vs cable for business internet when the question is last-mile technology rather than reserved vs shared capacity.

What to compare in the contract

  • Quoted download and upload rates, and any committed rate or burst rules
  • SLA metrics, how downtime is measured, and how credits are requested
  • Install window, construction charges, and who pays if the build slips
  • Demarc location, building access, and landlord or riser fees
  • Auto-renewal notice period and early-termination conditions
  • Backup path: different technology, different carrier, documented failover
