Dallas business IT

How do you choose business internet for a Dallas office?

Business internet is the longest lead item in any office project and the one most often chosen on the wrong number. Here is how to size bandwidth for a small office, what separates business service from residential, what an SLA really promises, and why internet gets ordered first.

How do I choose an internet provider for my Dallas office?

Start with the building, not the brochure. Find out which carriers already have equipment in your Dallas building, then choose on connection type, upload speed and support terms rather than headline download speed. Fiber first where it exists, business cable or fixed wireless where it does not. I am Anthony Omini at Cross River Tech, and internet is the first thing to order after signing a lease.

Key takeaways

  • Availability is decided per building, not per neighbourhood. Ask the property manager which carriers already serve the building before you compare anything.
  • Upload speed matters more than download for a modern office, because cloud files, backups and video calls all send data out.
  • Business service buys you support terms, a static public address and a repair commitment. That, not speed, is the difference from a residential plan.
  • Order internet the week you sign the lease. Install lead times at a commercial address run to weeks, and a fiber build runs longer.
  • If a day offline would stop the office, a cheap second connection from a different carrier is the least expensive insurance in the whole IT budget.

How do you choose an internet provider for a Dallas office?

Choose the building first and the provider second, because in commercial space your options are decided by what is already in the riser. Two suites on the same block can have completely different choices, and no coverage map will tell you that. The sequence I use is always the same.

  1. Ask the property manager which carriers have equipment in the building and tenants using it today. Not which are "available in the area". That question, asked before signing, has saved businesses from a suite whose only option was a months-long fiber build.
  2. Establish what type of connection each of them can deliver to your suite. Fiber, business cable or fixed wireless are different products with different behaviour, not different prices for the same thing.
  3. Size the bandwidth on how the office works, especially upload, rather than on the biggest number on the page.
  4. Compare the support terms. Business service, a static public address, and a written repair commitment are worth more than a faster headline speed on a consumer plan.
  5. Decide on term length with your eyes open about what happens if you move or the building changes hands.
  6. Decide whether the office can afford a day offline. If not, order a second, cheaper connection from a different carrier at the same time.

I am Anthony Omini, the owner of Cross River Tech in Dallas, and I do this with clients myself as part of every new office and every move. I do not sell circuits, take referral money from carriers or have a favourite brand, so the recommendation is only ever about what the building can actually get.

What internet speed does a small office need?

Less than most quotes assume on download and more than most assume on upload. A small professional office is not streaming films all day; it is syncing files, joining video meetings, running cloud applications and pushing backups out overnight. Those are upload-heavy, and upload is the number carriers advertise least.

OfficeTypical workloadSensible starting pointWhat pushes it higher
2 to 5 peopleEmail, cloud files, occasional video calls, cloud phonesA modest business connection with upload in the tens of megabits, not single digitsAnyone working with large files, or a cloud backup running during the day
6 to 15 peopleConstant cloud file sync, several concurrent video meetings, voice over IP, card paymentsA few hundred megabits down and upload of at least a hundred where fiber allows itDesign or engineering files, imaging, a guest network, remote staff connecting in
16 to 40 peopleAll of the above at once, plus backups and updates in the backgroundSymmetric fiber where it exists, sized so a busy afternoon does not feel different from a quiet oneVideo-heavy work, large uploads to clients, hosted applications, multiple sites
Any size with a server or imagingOff-site backup, remote access, large scansUpload is the constraint. Size for the backup window, not the browsing.Backups that must complete overnight, practice or design software with big files

Three rules that matter more than the exact figure. Advertised speed is a maximum under good conditions, not a floor. A connection with fast download and slow upload feels sluggish in a Microsoft 365 or Google Workspace office even though the brochure looks generous. And the difference in monthly cost between a plan that is comfortable and one that is tight is usually small compared with an hour of everyone waiting.

Fiber, cable or fixed wireless: what is the difference?

They are three different ways of getting a line to your suite, and the right one is usually decided for you by what reaches the building. Here is how they compare in general terms, without naming providers or quoting prices that vary by address and change constantly.

TypeWhat it isStrengthsLimitsBest for
FiberA glass line from the carrier into your suiteUsually the same speed up and down, steady under load, the strongest support terms, best suited to voice and videoOnly where it already reaches the building, otherwise a build with a long lead time and often a longer contractThe default choice for any office on cloud files, video calls or voice over IP, whenever it is available
Business cableBusiness-grade service over the same network as residential cableWidely available, quick to install, a lot of download speed for the moneyUpload far slower than download, capacity shared locally, lighter support commitmentsOffices where fiber is not in the building, and as a second connection behind fiber
Fixed wirelessAn antenna on the roof aimed at a carrier towerFastest to install because nothing has to be dug or pulled, works where wired options do notNeeds roof access and clear line of sight, and performance varies with distance and weatherA temporary line while fiber is built, a backup connection, or buildings with no wired option
Cellular backupA modem in the rack with a carrier data planCheap standby that switches in automatically on a business firewallNot a primary connection for an office of any size, and data allowances applyKeeping card payments, phones and key staff working through an outage

Note that this is about the line coming into the building. The cable inside your walls is a separate decision, covered in Cat6 vs Cat6a vs fiber for an office build-out, and the two get confused surprisingly often in quotes.

What does a business SLA actually mean?

An SLA, or service level agreement, is the carrier's written commitment about availability and repair, and it is the main thing you are buying when you pay business prices for a speed you could get cheaper at home. Read it for four things.

  • Availability commitment. Usually expressed as a percentage of uptime over a month. Higher figures generally come with fiber and dedicated services rather than shared ones.
  • Repair commitment. How quickly the carrier undertakes to restore service after you report a fault, typically expressed in hours for business fiber and much more loosely for shared services. This is the clause that matters at eight in the morning.
  • Credits. What you get back when they miss. Be realistic: a credit compensates for a fraction of a monthly bill, never for a lost day of business. The SLA is about priority, not compensation.
  • Support route. Whether you reach a business support queue with your account and circuit number, or the same line as residential customers. This difference is felt every single time something breaks.
Residential-grade serviceBusiness service
SupportConsumer queue, scripted troubleshootingBusiness queue, circuit identified, faster escalation
Public addressChanges without warningStatic address available, which voice over IP, VPNs and some software need
Repair priorityBest effortWritten commitment with credits attached
Terms of useOften prohibits business use outrightWritten for business use, including reselling to guests where allowed

None of that means the connection never fails. It means that when it does, you are in a different queue with a written obligation behind you. When an outage does happen, working out whether it is the carrier or your own equipment takes a few minutes and a fixed sequence, which is in the office internet is down: is it the ISP or your network.

How long does installation take, and why is internet ordered first?

Weeks, and sometimes considerably more, which is exactly why it goes first. Every other item in an office project can be compressed by paying more or working a weekend. A carrier install cannot. This is the realistic order at a new Dallas address.

  1. Before signing: confirm which carriers serve the building and whether fiber is already in the riser. Cheapest possible moment to discover a problem.
  2. Week of signature: place the order in the business name, request a static public address, state where the handoff must land, and get the install date in writing.
  3. Days after ordering: the carrier surveys the address. This is where "available" quietly becomes "available after construction" for some buildings.
  4. Landlord access agreement, if the carrier has to bring in a new line. A signature from the property owner is often the slowest step in the whole project and nobody chases it unless you do.
  5. Two to four weeks in: install date confirmed. Call to reconfirm rather than assuming, because dates slip and the carrier will not call you.
  6. Install day: the technician brings the line to a handoff box and proves it. Somebody should be there who knows where that box needs to go, because otherwise it lands wherever is easiest.
  7. After install: the firewall, already configured, connects to it and the office network comes to life. This part takes an afternoon if everything before it was done properly.

If your opening date is inside about four weeks, the sensible plan is to open on whatever installs fastest, usually business cable or fixed wireless, and put fiber on order behind it. The full coordination story, including where the carrier's box lands and who meets the technician, is in getting internet into a new office.

How long should the contract be?

As short as the pricing sensibly allows, unless a longer term is buying something specific such as a fiber build. Carriers offer better monthly rates for longer commitments, and that trade is fine as long as you understand what you are signing away.

  • Shorter terms cost more per month and keep you flexible. Worth it when the lease itself is short, when you may outgrow the space, or when a better option is being built nearby.
  • Longer terms lower the monthly cost and sometimes fund construction. If a carrier is building fiber to your address, expect them to want a term in exchange, and that is a reasonable deal.
  • Ask what happens if you move. Some agreements let you transfer the service to a new address inside their footprint, some charge for early termination regardless. This clause is invisible until the day you need it, which is usually the day you sign a new lease.
  • Ask what happens at renewal. Promotional pricing that reverts silently is common. Put the end date in a calendar with a reminder well before it.
  • Match the term to the lease where you can. A three-year circuit in a two-year suite is a problem you have created for your future self.
  • Keep the account in the business name, with billing and portal access held by the business rather than by a vendor. The same rule applies to your domain and your Microsoft 365 tenant, for the same reason.

One thing I will not do is tell you a price. Carrier pricing in Dallas varies by building, by term and by what the sales team has been told to hit this quarter, and any figure written here would be wrong by the time you read it. Get two or three written quotes for the same speed and term, and compare the terms as carefully as the number.

Do you need a second internet connection?

If a day without internet would stop the office, yes, and it is cheaper than most people expect. A second line from a different carrier, on a different technology, plugged into a business firewall that switches over automatically, turns a carrier outage into something most staff never notice.

ApproachWhat it costs youWhat it protectsSuits
Nothing, single connectionNothing monthlyNothing. An outage sends people home.Very small offices whose work can move to a coffee shop or a home desk
Cellular backup in the firewallA modest data plan and a modemPhones, card payments, email and a handful of key people at reduced speedMost small offices; the usual recommendation
Second wired circuit, different carrierA second monthly bill, usually a cheaper planNearly full operation through a single carrier's outageOffices where being offline costs real money: practices, agencies, anyone with clients on the phone
Two premium circuitsTwo full billsEverything, including performance during a failureRare at small-office scale, and usually over-specified

Two details make failover work properly. The second line should be from a genuinely different carrier on different infrastructure, because two services riding the same physical route fail together. And the failover has to be tested, not assumed. I unplug the primary during setup and watch what actually happens, which is how you learn that the phones did not follow.

What should you ask before you order, and who plugs it in?

Ask the landlord and the carrier a short list of questions, and have your IT person own the answers rather than the sales representative. Here is the list I work through, and what happens after the order.

  1. To the property manager: which carriers have equipment in this building and tenants on it, is fiber in the riser, where is the building telecom room, where can the handoff land in this suite, are there rules about riser work, roof access or after-hours access, and who signs a carrier access agreement.
  2. To the carrier: what is the actual install date in writing, is the address serviceable today or after construction, what is the upload speed, is a static public address included, what is the repair commitment, what is the term, and what happens if the business relocates.
  3. To yourself: can the office work for a day without this connection, and if not, what is the backup.

Then the ordering is in your business name, and the coordination is mine: telling the carrier where the handoff goes, chasing the date, meeting the technician or leaving clear instructions with the property manager, and connecting it to a firewall I have already configured at my desk so install day is a plug and a test rather than a scramble. Cabling from the handoff to the IT room is part of cabling and IT room setup, and the whole sequence for a new suite is on the office move and new-office IT setup page.

This is one piece of a bigger list. If you are opening a first office, who sets up the computers for a new Dallas business covers everything around it, and once the office is running, the connection is one of the things watched under a managed IT plan. I work with offices across the city and the wider metroplex, described on the Dallas service area page.

If you have an address, send it to me and I will tell you what is realistic there before you sign anything.

Questions people ask

How do I find out which internet providers serve my Dallas office building?

Ask the property manager which carriers have equipment in the building and which tenants are using them today, then check those specific carriers against your suite address. Online coverage checkers describe neighbourhoods rather than buildings and are frequently wrong for commercial space. If you have not signed yet, ask this during the tour, because the answer can be a reason to pick a different suite.

What internet speed does a 10-person office need?

For a typical professional office of that size, a few hundred megabits down with the highest upload the building allows is comfortable, and upload is the number to look at hardest. Cloud file sync, video meetings, voice over IP and backups all send data out. Where fiber is available, a symmetric plan removes the problem entirely. Where only cable is available, buy more than you think for the upload.

Is business internet worth paying more for than a residential plan?

Yes, for an office. What you are buying is not speed, it is a business support queue that knows your circuit, a static public address that voice over IP and VPNs need, and a written repair commitment with credits behind it. Residential terms of service also commonly prohibit business use, which becomes a problem at the worst possible moment when a fault is reported.

How far ahead should I order internet for a new office?

The week you sign the lease. At a Dallas commercial address the install runs to weeks when the carrier already serves the building, and much longer where fiber has to be built or a landlord access agreement is needed. Nothing else in an office project takes as long or resists being hurried as thoroughly. If the opening is close, open on a fast-to-install service and add fiber later.

Should a small office have two internet connections?

If losing a day of internet would cost you real money, yes. The cheapest useful version is a cellular backup in the firewall, which keeps phones, payments and key staff going during an outage for a small monthly amount. A second wired circuit from a genuinely different carrier is the next step up. Whichever you choose, test the failover by unplugging the primary rather than trusting the configuration.

Can you order and manage the internet service for us?

I coordinate it, and the account stays in your business name so you own the service. That means finding out what the building can get, reviewing or placing the order with you, specifying a static address, telling the carrier where the handoff must land, chasing the install date, meeting the technician, and connecting it to a firewall configured in advance so the office is working the same day.
