What is DIA? Discover How Dedicated Internet Access Can Drive Your Business Success

Over the past decade, businesses have recognized the need for faster, more reliable internet to meet customer demands. As a result, many turned to fiber—yet not all business fiber internet is created equal. In this article, we’ll break down what Dedicated Internet Access (DIA) is, how it compares to broadband fiber, and which dedicated internet providers businesses should consider when upgrading their service.

What does DIA stand for?

Sometimes sharing is great—whether it’s with friends, coworkers, or even a recipe at the grocery store.

However, when it comes to your business’s internet access, having your own connection is key. This is where DIA comes into play. But what is DIA?

DIA is a high-speed internet connection that is dedicated solely to your business.

Direct internet access is the best internet that your business can use to optimize its performance. Ample in the convenience that it supplies for businesses, here’s a list of the amazing benefits DIA service provides:

  • Guaranteed bandwidth – Your business is guaranteed the speed it pays for, compared to sharing the overall speed with another business.
  • High reliability – Consistent, uninterrupted service with minimal downtime.
  • Symmetrical speeds – Same upload and download speeds, no matter what your internet activity.
  • Enhanced security – Minimize the risk of unauthorized access and data breaches.

To simplify it, DIA service is like having your own private highway. You get to control the speed, flow of traffic, and it never gets congested because only your business uses it.

How does DIA work?

Understanding what DIA means is the first step in solving your business needs. The next step in the solution would be understanding how DIA works. In short, the answer is circuits.

DIA circuits are the physical cabling that carries the internet from your internet service provider (ISP) to your business. The most common material used for circuits is usually fiber or ethernet that’s installed from your dedicated ISP. Depending on the type of circuit your dedicated ISP uses, it can make a difference in factors like installation, latency (lagging), or even the levels of support you receive.

  • Type 1 DIA Circuit — Direct from ISP: Your ISP owns and maintains the entire connection, from their core network to your business. It’s the most reliable but also the most expensive.
  • Type 2 DIA Circuit — Rented Connection: Your ISP doesn’t own the entire path and instead leases part of the connection from another company. It’s more cost-friendly but troubleshooting is a bit more difficult because you have to deal with your ISP and another company.

To summarize, DIA circuits ensure speed, reliability, and security for your direct internet service.

DIA Pricing

The pricing for DIA varies, but it isn’t cheap. There are many factors that impact the costs. Here are the primary factors:

  1. Dedicated Bandwidth: A private, uncontended connection ensures consistent speed and performance.
  2. Infrastructure Costs: Digging trenches, laying cables, and using specialized equipment come at a cost.
  3. SLAs (Service Level Agreements): Ensured reliability, like guaranteed uptime, performance, and support, comes at a price.
  4. Symmetrical Speeds: Constant high-speed data transfer requires large amounts of bandwidth.
  5. Customization and Scalability: Businesses get tailored options and seamless upgrades.
  6. 24/7 Priority Support: Dedicated technical support around the clock helps reduce downtime but increases service costs.

Types of DIA

There are two types of dedicated internet access: DIA Fiber and DIA Fixed Wireless.

DIA Fiber

DIA fiber is the gold standard for direct internet access. Because it uses physical fiber-optic cables that must be deployed underground by technicians, it is extremely reliable and less affected by weather conditions or other disruptions.

DIA fiber requires trenching, which means creating underground pathways for fiber-optic cables. This process involves:

  • Excavation: Digging through roads, sidewalks, or private property to install conduits for fiber cables.
  • Permits and Regulations: Obtaining approval from local governments and utility companies to prevent infrastructure disruptions.
  • Labor and Equipment: Using specialized machinery and skilled workers to properly install and protect the fiber lines.

Though more expensive to install and requiring a longer deployment window, DIA fiber delivers the fastest speeds, lowest latency, and highest bandwidth available on the market.

DIA Fixed Wireless

Now that you know what DIA fiber is, how does that differ from DIA fixed wireless? Unlike T-Mobile or Verizon which use 4G LTE/5G cell towers but label it as fixed wireless, true fixed wireless is a distinct internet technology that relies on a dedicated line-of-sight signal sent to an antenna, used exclusively by the business and its internet service provider (ISP).

Since fixed wireless operates on its own signal—not a shared 4G LTE/5G cellular network—businesses still benefit from guaranteed bandwidth, high reliability, symmetrical speeds, and advanced security, similar to fiber-optic internet.

Two major benefits that businesses gain from using fixed wireless over traditional fiber-optic internet are cost-effectiveness and rapid deployment. Unlike fiber, fixed wireless doesn’t require a long, expensive installation process. Since fiber installation involves engineers, technicians, and sometimes multiple companies to build the necessary infrastructure, the costs can add up quickly. In contrast, fixed wireless uses an antenna, making both installation and maintenance significantly faster and more affordable than fiber-optic service.

If DIA fiber is like having your own private highway, fixed wireless is like having your own private elevator. Because you’re the only person using it, you never have to stop on multiple floors to pick people up or deal with the lunchtime rush in the office.

We know how they are similar, let’s see how they differ:

DIA vs. Broadband Fiber

Now that we’ve answered, “What is DIA?” and you understand how DIA works, the next question you have is surely, “What is broadband fiber?” Similar to DIA fiber, broadband fiber is a high-speed internet connection that has the capability to deliver information at extremely fast speeds. The major difference between DIA vs. broadband fiber is that broadband is shared amongst multiple users or businesses.

If direct internet access is a private highway, used solely for one business, broadband is the express lane on a public highway. It still gets you where you need to go in a hurry, but there’s a car in front of you, and behind you in the fast lane.

Different than DIA, broadband internet is typically less expensive, being the choice that most small- and medium-sized business select. If you’re just starting your business, either as a solo-entrepreneur or a small team, business broadband internet might be the choice for you.
