Comparison
Dedicated internet vs broadband for business
Dedicated Internet Access reserves capacity for your site and usually comes with a written service-level agreement. Business broadband shares capacity in a neighborhood or building node and is typically sold as best-effort. The decision is about risk, install timeline, and contract teeth, not a slogan about “upgrading.”
| Factor | Dedicated internet (DIA) | Business broadband |
|---|---|---|
| Capacity model | Reserved for your site | Shared across a node or building |
| Speed shape | Usually symmetrical upload and download | Often faster down than up |
| SLA | Uptime, latency, and repair targets in writing | Best-effort or a lighter commitment |
| Performance at peak | Committed rate should hold when neighbors are busy | Can soften when the shared node is congested |
| Install timeline | Weeks to months if construction or a riser build is required | Often days to a few weeks |
| Typical fit | Cloud-heavy ops, voice at scale, payments, revenue-critical sites | Offices, retail, and branches that can tolerate shared capacity |
What dedicated internet access actually is
DIA is a circuit sized and sold for one customer. The carrier commits a rate (and often a burst rule) to your demarc, then writes repair and availability targets into the contract. The last mile is often fiber Ethernet, but Ethernet over copper and dedicated fixed wireless can be DIA too. If the quote does not say “dedicated” and does not attach an SLA, treat it as broadband no matter what the sales deck calls it.
What business broadband actually is
Business broadband is a commercial wrapper on a shared access network: cable, DSL, or shared fiber into a building. You get a faster install, a lower monthly line item, and enough throughput for many sites. You do not get exclusivity on the node. Afternoon congestion, lighter repair clocks, and asymmetrical upload are the usual trade-offs. That is not a failure of the product. It is the product.
When dedicated internet is the right call
Choose DIA when an outage or a slow upload window has a measurable operating cost: hosted voice across many seats, all-day cloud ERP, payment processing, or a site that cannot wait on a best-effort ticket. Also choose it when you need contractual remedies (credits, mean-time-to-repair) that you can actually invoke. Availability still has to be confirmed at the suite address; a dedicated product you cannot build is not a strategy.
When broadband is the sensible primary
Keep broadband as primary when the site can live with shared capacity, when construction would delay occupancy, or when you would rather put budget into a wireless or LTE backup than into a reserved circuit. Many Canadian multi-site businesses run broadband at branches and reserve DIA for headquarters, data rooms, or any location that hosts the phone system. Write that distinction down so renewals do not quietly “standardize” every site onto the same SKU.
Shared fiber is not dedicated internet
Buyers get quoted “fiber” and assume they bought DIA. GPON and other shared optical designs can still contend with other tenants in the building. Ask three questions before you treat a fiber quote as dedicated: is the bandwidth reserved, is the SLA attached to this circuit (not a marketing PDF), and is the handoff Ethernet to your suite or a shared ONT in the riser? If those answers are fuzzy, you are comparing the wrong products.
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
- Committed information rate vs advertised speed, including upload and 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
