Fixed wireless broadband: how it works, speeds and limits
Fixed wireless sends your internet by radio from a provider's tower to an antenna on your home. Speeds are often usable for streaming and video calls, but two nearby homes can get very different results because of the radio path and how many people share the tower.
- Your signal depends on the path between your antenna and the tower, not just the plan you pick.
- Speeds are shared, so evenings can be slower than mornings.
- Ask about line of sight, tower load, data limits and install terms before you order.
How a fixed wireless link gets from tower to your home
Fixed wireless carries internet by radio between a provider's tower or rooftop radio and a small antenna fixed to your home. No cable runs down your street. The tower itself connects to the wider internet through fiber or another high-capacity link, often called backhaul.
At your home, an outdoor antenna or an indoor receiver picks up the signal. A cable feeds it to a router, and your devices connect as they would on any home network. Some plans use a cellular network with an indoor box instead of a roof antenna. Ask your provider which type you would get, because the limits differ.
What speeds are realistic, and why advertised numbers vary
Fixed wireless speeds vary more than most wired service. The ranges below are typical, not promises.
| Measure | Commonly seen | What changes it |
|---|---|---|
| Download | About 25 to 300 Mbps | Distance, obstacles, tower load, equipment |
| Upload | About 3 to 30 Mbps | Radio path and plan design |
| Latency | About 15 to 60 ms | Signal quality, tower load, backhaul |
An advertised speed is usually a top figure or a typical figure for an area. Your home may land below it. The federal benchmark for fixed broadband has been 100 Mbps down and 20 Mbps up, but check whether it has changed. Many fixed wireless plans sit below one or both numbers.
Providers are generally required to show a broadband label at the point of sale. It should list typical speeds, latency and data limits. Ask to see it for the exact plan and address.
Line of sight, trees and distance: what affects your signal
Radio signals weaken with distance and get blocked by objects. This is the main reason two neighbors can see different results. One has a clear view of the tower from the roofline. The other sits behind a hill or a stand of trees.
- Line of sight: some setups need a mostly clear path to the tower. Others tolerate a little blockage. Ask which applies.
- Trees: leaves can absorb signal, and trees grow. A path that works in winter may weaken in summer.
- Distance: farther homes usually get lower speeds.
- Antenna height: a higher mounting spot can clear obstacles.
- Weather: heavy rain, snow or wind can cause dips, and some signal types are more sensitive than others.
A provider may check your address by map, by a site survey, or by trying the connection after install. Ask which method they use and what happens if the signal turns out weak.
Shared capacity: why evenings can be slower than mornings
A tower has a fixed amount of capacity, and everyone connected to it shares it. When many homes stream, game and work online at the same time, each home gets a smaller slice. That is why evening speeds can drop below what you see at mid-morning.
A strong signal doesn't fix a crowded tower. Ask whether the tower or sector serving your address is near its limit, and whether the provider is adding capacity. Some providers will say. Others cannot. Either answer is useful to know.
Upload speed, latency and data policies to check
Upload speed matters for video calls, cloud backups and sending large files. Fixed wireless upload is often much lower than download. If you work from home, check the upload figure first.
Latency is the delay in each round trip. Fixed wireless is often fine for calls and streaming, but it can wobble when the tower is busy. Our guide to latency, ping and jitter explains what to look for in a speed test.
Data policies vary by plan and change often. Some plans have a hard cap, some slow you down after heavy use, and some have no limit. Read how data caps work, then ask what happens at the limit and whether video quality is reduced.
Who fixed wireless suits and who should look elsewhere
Fixed wireless can suit homes where cable and fiber don't reach, or where installation would cost too much. It often works for a small household that streams, browses and takes occasional video calls.
Look elsewhere, or compare carefully, if you have heavy upload needs, many users gaming at once, or a home surrounded by dense trees or hills. Our guide to getting internet in a rural area compares other options.
If cost is a concern, Lifeline is a federal program that may lower a monthly bill by $9.25 ($34.25 on Tribal lands). Eligibility depends on income or other program participation, and not every provider takes part. The Affordable Connectivity Program ended in June 2024.
Questions to ask before you order
- Is this a roof antenna or an indoor receiver, and does it need line of sight?
- Can you check my exact address, and how?
- What download, upload and latency are typical at my address, in the label?
- Is the tower near capacity at busy times?
- Is there a data cap, soft cap or slowdown policy?
- Is installation by a technician or self-install, and what are the fees?
- What is the contract, return or cancellation policy if the signal is weak?
Common questions
How does fixed wireless broadband work?
A provider's tower sends a radio signal to an antenna fixed to your home. A cable links the antenna to a router, and your devices connect to that router. The tower connects to the wider internet through a separate high-capacity link.
Is fixed wireless internet fast enough for streaming and video calls?
Often, yes, if your signal is solid and the tower isn't crowded. Check the typical download, upload and latency on the broadband label, and ask how speeds hold up in the evening.
Does weather affect fixed wireless internet?
It can. Heavy rain, snow, wind that moves the antenna, and leafy trees may cause slowdowns or short drops. How much depends on the type of signal and your path to the tower.
Do you need line of sight for fixed wireless internet?
Some setups do, and some work with partial blockage. Ask your provider which applies to your plan, and how they will check your address.
