Ready together for new oppor­tunities with 5G.

5G long since heralded the future of mobile communication. And thanks to Swisscom, Switzerland was the first country in Europe to adopt it. With 5G, mobile digital experiences can be on a par with high-speed Internet at home. We all benefit from this. In our daily lives. At work. And in our free time.

The best network.
Even better with 5G.

Even in its first expansion stage, the fifth mobile generation already represents a quantum leap in technology. 5G allows us to enjoy even better applications in better quality. Streaming, gaming, meeting: whenever and wherever, no matter how many others are doing the same thing at the same time.

More speed

Each generation of mobile communication has brought ever greater download speeds in several expansion stages.

More capacity

Graphic shows the number of simultaneous mobile radio users per transmitter - 3G: 40 users, 4G: 400 users, 5G: 40,000 users

The number of simultaneous mobile users per transmitter is limited.1 When there are a lot of users, this can lead to disruption when switching from one mobile cell to another, such as on a train or on the motorway.

We have been providing 99% of the Swiss population with 5G on the first 5G network in Europe since 2021. With 5G+, we are currently bringing even more speed to Switzerland’s best network.

The Swisscom network has been the undisputed winner in countless network tests for years. And since its launch in 2019, our 5G network has also been a front-runner.

With 5G, data transmission response times are reduced to a few milliseconds. This is crucial, for example, for industrial production, robotics or real-time applications.

The most sustainable network. Even more sustainable with 5G.

Data transmission in mobile communications uses electromagnetic fields. The adaptive antennas that are newly deployed with 5G transmit directly towards the devices being used, with hardly any signals emitted in other directions. This reduces the amount of radiation emitted and increases energy efficiency.

Less energy consumption

Graphic shows power consumption per 1GB of data - 3G: 40 Wh/GB, 4G: 3.5 Wh/GB, 5G: 1Wh/GB

It takes significantly less power to transmit 1 GB of data with 5G than it does with previous mobile technologies.

Lower radiation levels

The measured values for 4G and 5G in this example come from a field study conducted by OFCOM in 2022. All the measurements from this study show that the average value of the measured field strength is lower for the adaptive antennas used for 5G than it is for the conventional antennas used for 4G, at the same transmission power. The limit is the precautionary installation limit value for places of sensitive use. Detailed information and study2

A study by the University of Zurich and Empa has shown that 5G reduces energy consumption in the network and on devices and has positive effects overall on climate protection.

Several Federal Government studies from 2022 confirm that the new adaptive transmission technology of 5G improves sustainability of the mobile network.

The radiation emitted by our mobile communication systems is well below the legal limits. In addition, in special protection areas, limit values in Switzerland are up to 10 times stricter than those recommended by the WHO.

New transmission technology

We use the latest transmission technology for 5G: adaptive antennas transmit targeted signals to active end devices such as smartphones or laptops. Almost no signals are transmitted in other directions, significantly reducing overall radiation levels and ensuring maximum capacity in the network.

5G offers higher Internet speeds and shorter response times (lower latency). This brings advantages for a wide range of applications, including productive collaboration, streaming and gaming as well as process optimisation in production plants etc.

The effects of mobile radiation on humans, animals and the environment have been researched intensively. Provided recommended limit values are observed, no evidence has been found to indicate that 5G represents a threat to health.

More about mobile technology and health

  • 5G offers good coverage both outdoors and indoors, enabling speeds of up to 1 Gbit/s
  • 5G+ is a higher bandwidth version of 5G with download speeds of up to 2 Gbit/s.

Swisscom provides 5G mobile coverage to 99% of the Swiss population. The very first generation of 5G devices only supports one frequency band with 5G (N78, 3.6 GHz), so these devices can only use 5G+. Nonetheless, these smartphones are compatible with the latest 4G standards, thus ensuring that there are hardly any limitations in the network service.

At the current stage of development of the 5G mobile communications standard, it is possible that a device may display 5G, but actually use 4G (not only within the Swisscom network). This applies in particular to the first 5G devices from 2019.


The latest mobile telephony standard currently offers speeds of up to 2 Gbit/s.

4G+/LTE Adanced

4G+/LTE Advanced enables a theoretical bandwidth of up to 700 Mbit/s on the mobile phone network. Speeds of up to 300 Mbit/s are already available to 90% of the Swiss population and 72% can access speeds of up to 500 Mbit/s.

4G/LTE (Long Term Evolution)

4G/LTE is the successor to 3G technology. It represents the fourth generation of mobile technology. 4G currently enables mobile broadband data rates of up to 150 Mbit/s.


3G is the third generation of mobile technology and includes UMTS, HSPA and HSPA+. 3G enables speeds of up to 42 Mbit/s and covers 99% of the Swiss population.


2G is the second generation of mobile technology that was phased out by the end of 2020 after more than 25 years. It includes mobile technology such as GPRS, EDGE and GSM.

Carrier aggregation (frequency bundling)

Carrier aggregation is a way of increasing the data rate per user by connecting several frequency blocks together. It means a much larger number of users can use a radio cell simultaneously with higher speeds.

1 The capacity calculation is based on the assumption that the devices of the specified number of users are connected to the same mobile cell at the same time and achieve the same average data throughput. Depending on the source (and underlying data throughput), 5G can connect 100 to 1000 times more devices or users compared with 4G.

2 Between autumn 2021 and spring 2022, the Federal Office of Communications (OFCOM) conducted an extensive field trial on mobile network radiation emissions. The example shows the average values for 5G (frequency band 3580–3700 MHz: 0.17 V/m) and 4G/LTE (frequency band 1805–1880 MHz: 0.62 V/m). For this example, measurements were taken from the roof of a bicycle shed on the premises of the Federal Office of Public Health (FOPH) in Liebefeld, Switzerland. All measurements from the field trial confirmed what was already known – that, overall, radiation levels measured from adaptive antennas (5G) are significantly lower than those from conventional antennas (3G and 4G). The measurements also show that the radiation levels are far below the precautionary low installation limit values of 4–6 V/m, which apply to places of sensitive use. And these are only a fraction of the frequency-dependent exposure limit values of 28–61 V/m.
