Fixed wireless internet uses a radio tower to send data to an antenna on your roof, instead of running cables through the ground or air to your house
Fixed wireless is a real alternative to cable and fiber, not a backup plan. A company installs a small antenna (usually the size of a paperback book) on your roof or the side of your house, pointed at a nearby tower. That tower sends data over radio waves instead of through physical cables. You get a modem inside your home that connects to the antenna, and from there you plug in your devices or connect wirelessly.
The main difference from satellite internet: the tower is much closer to you — typically within 5 to 10 miles — so the signal travels faster and with less delay. The main difference from cable or fiber: there are no trenches or poles involved, which is why fixed wireless can reach rural areas where digging would cost too much.
Key Takeaways
- Fixed wireless requires a clear line of sight between your roof and the tower, so trees, hills, or tall buildings between you and the tower can block or weaken the signal.
- Speeds and data limits vary by provider and location — some offer 50 Mbps with no cap, others offer 100+ Mbps but with monthly data limits that reset or throttle you after a threshold.
- Installation usually takes one visit and costs $0 to $200 depending on the provider; the antenna and modem are typically included in the service fee.
- Fixed wireless works best for households that browse, stream, and video call, but may struggle if multiple people game online or upload large files at the same time.
How the signal gets from the tower to your home
The antenna on your roof receives a radio signal from the tower and converts it into data your modem can use. The modem then broadcasts that data as WiFi inside your home, or you can plug devices directly into the modem with an ethernet cable. The whole chain depends on a clear path between the antenna and the tower — if trees grow in the way, or if a building blocks the line of sight, your speeds drop or the connection cuts out.
This is different from satellite, where the signal travels 22,000 miles to space and back, adding a delay called latency. Fixed wireless latency is usually 20 to 50 milliseconds, similar to cable. That matters if you play online games or use video calls — satellite latency (500+ milliseconds) makes both nearly impossible.
What speeds and data limits you actually get
Fixed wireless speeds range from 25 Mbps to over 100 Mbps depending on which provider serves your area and how close you are to the tower. T-Mobile Home Internet, for example, advertises 72 Mbps average read speeds in its coverage areas. Verizon 5G Home Internet advertises 300+ Mbps in some locations. Smaller regional providers may offer 50 Mbps or less. The only way to know what you would get at your address is to check the provider's coverage map or call them directly.
Data limits are where fixed wireless gets complicated. Some providers (like T-Mobile Home Internet) have no monthly cap — you pay one price and use as much as you want. Others throttle you after you hit a threshold, meaning your speeds drop sharply once you use a certain amount of data in a month. A few still charge overage fees. Before you sign up, ask the provider directly: Is there a monthly data limit? What happens if I go over it? Does the limit reset monthly or roll over?
Installation and equipment costs
A technician visits your home, assesses whether you have a clear line of sight to the tower, and installs the antenna on your roof or exterior wall. The visit usually takes 30 minutes to an hour. Most providers include the antenna and modem in the service fee — you pay a monthly bill but own nothing. A few charge a one-time installation fee ($100 to $200) or require you to buy the equipment upfront.
If the technician finds that trees or buildings block the signal, they may suggest moving the antenna to a different wall or a higher point on your roof. If no location works, they will tell you the service is not available at your address. This is one reason to ask about fixed wireless availability before you commit to a provider — some areas have coverage, others do not, and the coverage map is not always precise.
When fixed wireless works well and when it does not
Fixed wireless handles everyday internet use well: browsing, email, streaming video in one or two rooms at a time, video calls, and schoolwork. If your household has one or two people online at once, speeds of 50 to 100 Mbps are usually enough. The lack of cables also means no digging up your yard and no waiting months for installation.
Fixed wireless struggles when multiple people use the internet heavily at the same time — for example, one person gaming while another streams 4K video and a third uploads files. It also struggles if you live in a dense urban area where many customers share the same tower, which can slow everyone down during peak hours. And if you have trees that grow taller over time, or if a neighbor builds a structure that blocks your line of sight, your speeds may degrade without warning.
How fixed wireless compares to cable, fiber, and satellite
| Type | Speed range | Latency | Data limits | Installation time |
|---|---|---|---|---|
| Fixed wireless | 25–100+ Mbps | 20–50 ms | Varies by provider | 1 visit, 1–2 weeks |
| Cable | 50–500+ Mbps | 10–30 ms | Usually none | 1 visit, 1–4 weeks |
| Fiber | 100–1000+ Mbps | 5–15 ms | Usually none | 1–2 visits, 2–8 weeks |
| Satellite | 25–100 Mbps | 500+ ms | Usually yes | 1 visit, 1–2 weeks |
Cable and fiber are faster and more reliable if they are available in your area, but they require digging or running lines to your home, which can take weeks or months. Satellite reaches anywhere but has high latency and data limits that make it unsuitable for gaming or heavy use. Fixed wireless sits in the middle: faster and lower-latency than satellite, available in more places than fiber, and installed faster than either.
Questions to ask before you sign up
Before you commit to fixed wireless, contact the provider and ask these specific things: What read and upload speeds can I expect at my address? Is there a monthly data limit, and what happens if I exceed it? What is the installation fee, and do I own the equipment or rent it? What is the contract length, and what are the early termination fees? Can I cancel if the speeds do not match what was promised?
Also ask whether the provider has a trial period or money-back may provide — some do, some do not. And ask about their customer service: Is there a local number to call, or only online chat? Do they have a physical office you can visit if something goes wrong? These details matter more than the advertised speed, because a fast connection that you cannot get help with is worse than a slower one with good support.
Frequently Asked Questions
Will trees or bad weather affect my signal?
Trees between you and the tower will weaken or block the signal. Heavy rain can also reduce speeds temporarily, though most fixed wireless systems are designed to handle normal weather. Snow on the antenna can block the signal until it melts or you brush it off. Ask the technician during installation whether trees are a concern at your specific address.
What happens if I move or want to cancel?
Most fixed wireless plans have no long-term contract, so you can cancel with 30 days' notice. If you move, the service does not transfer — you would need to check availability at your new address and have a new antenna installed. Some providers charge an early termination fee if you cancel within a certain period; ask about this before you sign up.
Can I use fixed wireless for working from home?
Yes, if your work involves video calls, email, and web browsing. Speeds of 50 Mbps are usually enough for video conferencing and most office tasks. If your job requires uploading large files regularly or running bandwidth-heavy software, ask the provider about upload speeds specifically — fixed wireless upload is often slower than read, which can be a bottleneck.
How is fixed wireless different from 5G home internet?
5G home internet is a type of fixed wireless that uses newer 5G radio technology instead of older 4G LTE. 5G can offer faster speeds and lower latency, but it requires you to be close to a 5G tower. Not all areas have 5G coverage yet. If a provider offers 5G home internet in your area, it is worth comparing to their 4G fixed wireless option, but the basic setup and installation are the same.
What if the provider says my address is not covered?
Coverage maps are not always exact, especially in rural areas. Call the provider directly and give them your full address — they can check their system more precisely than the online map. If they confirm no coverage, ask when they expect to expand to your area. You can also check back in a few months, as providers add coverage regularly.
