AT&T sells two very different products to businesses. One runs on fiber. The other runs on older copper or coax lines. Both show up on the same quote sheet. Both get pitched as "business internet."
They are not the same thing.
If you are picking between them, or your rep just told you fiber is finally available at your building, here is what actually changes.
Speed is the obvious one. Upload speed is the real one.
Cable gives you fast downloads and slow uploads. A typical plan is 300 Mbps down, 20 Mbps up. That works fine for browsing, email, and a few people on Zoom.
Fiber is symmetric. 500 down means 500 up. 1 Gig down means 1 Gig up.
If your team sends video files, runs phones over the internet, or backs up to the cloud, upload speed is what you feel every day. That is when fiber starts to pencil out.
Reliability is where the gap gets wide
Cable runs on a shared line. Your speed drops when the neighborhood gets busy. Outages hit a whole block at once.
Fiber is a private line from your building to the AT&T network. You get the speed you pay for, all the time. Outages are rare, and when they happen, they tend to get fixed faster because the line is dedicated.
AT&T puts an SLA on fiber. That means they owe you a credit if the service goes down for too long. Cable does not come with an SLA in most markets. Read the contract. If the SLA section is blank or vague, it is not fiber.
Price is closer than you think
People assume fiber costs a lot more. It used to. It does not always now.
In Atlanta this spring, we saw AT&T fiber at 500 Mbps quoted in the $115 to $145 range. Cable plans at 300 Mbps were quoted at $95 to $120.
So you are paying maybe $25 more a month for a faster, more reliable, symmetric product with an SLA. That math works for most businesses that lean on the connection.
In some buildings the fiber price is actually lower than cable because AT&T is trying to fill capacity. Always ask for both quotes. Always.
Contract terms are not the same
Cable contracts from AT&T tend to be one to two years with steep early termination fees. Renewal rates jump. The fees on the bill grow every year. We see Broadcast TV style charges and "network access" fees that the carrier sets itself.
Fiber contracts are usually two or three years, and the price is locked. That is a real difference. With fiber, the number on the contract is the number on the bill, month after month. With cable, the number on the contract is the starting point.
If you are signing a three year fiber deal, put the renewal date in your calendar the day you sign. Ninety days before that date is when you negotiate. Miss it and you may roll into a higher rate.
When cable still makes sense
Cable is the right pick when:
- Fiber is not lit at your building and the install quote is over $5,000
- You have under five people and nobody uploads much
- You need service in two weeks, not two months
Fiber install can take 30 to 90 days. Cable can be live in a week. Sometimes timing wins.
How to actually choose
Get both quotes from AT&T. Get a quote from one other carrier in your building, usually Comcast Business or a local fiber provider like Crown Castle. Put all three side by side.
Look at the monthly price, the upload speed, the contract length, and the SLA. One of the three will be the clear winner. It is almost never the first thing the rep pitched.
We did this for a 22 person marketing firm in Augusta last quarter. The rep led with cable at $129. The fiber quote, once we asked, was $148 with an SLA and triple the upload. They saved nothing on the line item, but they stopped losing two hours a week to outages.
That is the trade most owners would take.
