Cable in the building vs a radio on the roof
If cable's already lit on your floor, stay on it. That's the honest answer for a lot of Downtown, Back Bay, Seaport, and Cambridge offices.
The question changes when the "cable quote" is actually a build, the fiber ETA is a quarter out, or you need a second path that doesn't share a conduit. That's what this is for. Not a brochure scorecard.
Comcast Business is the cable incumbent in a lot of Greater Boston commercial buildings. Netafy is a local ISP. We mount a radio on the roof or exterior and hand off ethernet in the closet. Different path. Different wait.
For the broader menu — cable, fiber, and wireless — see business internet options in Boston for 2026. This post is for people looking at a Comcast Business alternative because the wired quote came back as construction.
Two different paths into the building
Cable (Comcast Business and similar): Uses the coax that's already in the building, or a fiber/coax build if it isn't. When the plant is live, turn-up is usually an inside handoff. When it isn't, you're in construction, landlord access, and city permits. We're not inventing Comcast's rate card, SLA, or advertised tiers. Those are on their quote, and they change by building.
Rooftop fixed wireless (Netafy GigTier): A tech mounts a receiver on the roof or exterior and runs a cable to your closet. No street trench. Our Boston pages publish a typical install of 1–2 weeks from a signed order, symmetric speeds up to 1 Gbps, and no construction into the street.
That's the frame: cable already in vs a rooftop path that doesn't wait on a street opening.
Install time
| Cable in the building | New wired build | Netafy rooftop wireless | |
|---|---|---|---|
| Typical path | Coax or fiber already in the riser | Street work, permits, landlord access | Radio on the roof or exterior |
| What you wait on | Inside wiring, a tech visit, building access | Construction and city process | Roof access and a site visit |
| Boston reality | Often the fastest path if the plant is live | Months, if fiber isn't in | Published as 1–2 weeks. No street work. |
| Business stays open? | Usually | Street and riser work can bother neighbors | Usually one visit |
If Comcast is already on your floor, keeping it as primary is the practical call. The interesting case is a build, a long fiber ETA, or a second path that doesn't share conduit.
Speeds — and what we won't invent
Netafy publishes GigTier as symmetric service up to 1 Gbps for qualifying Boston-area buildings. Business broadband from $199/mo. Dedicated (DIA) from $399/mo. That's on the Boston business internet page.
Comcast Business sells cable and fiber products. Download is usually the headline number. Upload depends on the product in that building. We're not listing Comcast speeds or prices we can't cite. Get a written quote for your suite. Compare upload, not just download, if the office lives on Zoom, cloud backup, or VoIP.

Two underground providers are still one backhoe
A common Boston outage isn't "the ISP had a bad afternoon." It's a backhoe, a flooded basement, or a riser hit that takes every underground circuit at once. Two providers in the same conduit aren't diverse. They're two invoices on one path.
That's why rooftop wireless as backup still makes sense when you keep Comcast as primary. The wireless hop doesn't travel the same underground plant. Backup internet for Boston offices covers SD-WAN failover and the $50/mo Diverse Backup add-on we publish for automatic shift.
If compliance asked for "diverse access," ask the wired providers where their laterals enter. Same vault? You don't have diversity yet.
Contracts and who you call
Netafy's published business FAQ is a 12-month initial term, then month-to-month. The Boston page also says we don't require long multi-year lock-ins. Confirm the term on the order you sign.
Cable business service often comes with a term, early-termination language, and a national support queue. We're not inventing Comcast's current contract length or SLA credits. Read the service order. If you want someone who can talk about a specific Boston building, ask both sides before you sign.
When cable wins
Stay with cable when:
- The building already has a live Comcast Business drop, and the product you were quoted actually meets upload and reliability
- You don't need a second physical path
- A rooftop install is blocked — no roof rights, a landlord who won't approve an antenna, or a site we can't reach
Cable in the building isn't a bad technology. It's a different path. The Boston problem is treating a construction wait like "just how business internet works."
When a rooftop alternative makes sense
Look at Netafy as primary, or as a Comcast Business alternative, when:
- Fiber or a new wired lateral is a construction project and you need service in weeks, not a permitting season
- You want path-diverse backup that doesn't share a conduit with the incumbent
- The office is temporary — project trailer, swing space, pop-up — and a street build doesn't pay back
- The building is older and the riser or conduit fight is the real delay, not the radio
Why Boston businesses choose fixed wireless is the longer rooftop-vs-fiber-build version.
What to put on the quote request
Send both providers the same facts: suite address, bandwidth you need, primary or backup, and your go-live date. For Netafy, use the Boston quote form, not the home availability checker. Call 877-412-9434 if that's faster. Published plan ranges are on business internet pricing. For Comcast, use their business quote path and ask if the building is already on-net, or if the date depends on construction.
If the job is a show window, a multi-site warehouse, an office that has to open before fiber, or a building that only has Comcast, those write-ups are here: event dual-path wireless, managed WAN for logistics, office internet before fiber, second internet option for buildings.
