Understand the connection where you live, work and travel
Signal map collects factual information about mobile coverage, 4G, 5G, mobile internet and public Wi-Fi networks in Sweden.
How We Work
A step-by-step methodology built for measurable outcomes.
Define location and use
Start by specifying where the connection will be used and which activities are most important, such as video calls, remote work, streaming or travel. The need determines which technical properties should be prioritized.
Compare independent data
Put the operators' coverage maps, authority information and documented measurement methods in relation to each other. Note that maps normally describe estimated outdoor coverage and do not guarantee a specific indoor speed.
Check the conditions on site
Confirm the conclusion by measuring at different times and positions, especially indoors or in areas with varying loads. Document signal, speed and response time separately as they describe different parts of the connection quality.
Core Competencies & Services
Structured solutions delivered with precision and reliability.
Coverage in a geographic context
Learn how terrain, built-up areas, distance to base stations and indoor environment affect mobile signal strength. The guide differentiates between theoretical operator coverage and the experience that may actually occur in a particular location.
4G and 5G explained
Get a clear overview of differences in capacity, response time, frequency bands and areas of use for 4G and 5G. Technical concepts are explained without exaggerating the results or presenting them as identical everywhere.
Mobile internet in practice
Compare mobile broadband, internet sharing and fixed connections based on data volume, stability, latency and household needs. The information also covers how load, subscription terms and router location can affect usage.
Frequently Asked Questions
Clear answers to common questions about our services.
What is the difference between coverage and speed?
Coverage describes whether a device can connect to the mobile network in a certain location, while speed indicates how fast data can be transferred. A location may therefore have useful coverage but low speed due to high load, limited capacity, weak signal or characteristics of subscription and equipment.
Is 5G always faster and better than 4G?
5G can provide higher capacity and lower response time under the right conditions, but the actual benefit depends on frequency band, network deployment, load, device and subscription. A well-functioning 4G network can therefore be more stable or sufficient for many everyday uses.
How can I rate public Wi-Fi?
Check that the network name comes from the responsible site and avoid networks of unclear origin. Use updated devices, prefer websites with HTTPS, enable two-factor authentication and avoid sensitive transactions if the network's security cannot be verified.
Why is my experience different from a coverage map?
Coverage maps are often based on models, measurements or calculated probabilities and may have a different resolution than the environment in which you are located. Wall material, terrain, vegetation, weather, network load, the phone's antenna and exact position can all affect the perceived connection.
Make the terms of the connection comprehensible
Use Signalkarta as a neutral basis when you compare mobile networks, mobile internet and public Wi-Fi environments in Sweden. Start with the basics and move on to the method that suits your location.
Comparison of connection types
Different connections are suitable for different situations. The table describes general characteristics; actual function is affected by location, equipment, network load, subscription and security configuration.
| Connection | Common use | Central strengths | Important limitations |
|---|---|---|---|
| 4G | Everyday mobile data, calls and internet sharing | Wide availability and established compatibility | Capacity and response time vary with signal and load |
| 5G | Higher data capacity, modern mobiles and some fixed wireless services | Can provide higher capacity and lower response time under the right conditions | Deployment, frequency bands and actual performance differ between locations |
| Public Wi‑Fi | Temporary connection at libraries, hotels, stations and cafes | Can reduce mobile data consumption and provide local internet access | The security, quality and authenticity of the network must be checked |
| Fixed broadband | Permanent connection in home or workplace | Can offer predictable capacity and stable connection | Requires access to infrastructure and is less flexible when moving |
Speed, latency and stability are separate properties. A single measurement result is not sufficient to describe a connection over time or in an entire geographical area.
