Mobile phone mast maps

On 4 January 2010, the Swedish Post and Telecom Authority took down its 'Transmitter Map'. Mobile providers had argued that the locations of the masts were trade secrets that should remain confidential. The Swedish Post and Telecom Authority then stopped collecting information about mobile phone masts, which removed the basis for the 'Transmitter Map'.

Masts are part of the landscape, and the Land Survey’s topographical map shows all masts and towers. Before the advent of mobile telephony, masts were rare, so it is reasonable to assume that a mast shown on a map is a mobile phone mast. In built-up areas, masts are not usually required to support antennas as these can be mounted on buildings. The map symbol for a mast is: Mast , tower , tower with mast on top .

Lantmäteriet (Land Survey)

Although Norway does not have a programme for taking measurements, it does have a radiation calculator. This is why both 'no' and 'yes' are listed under 'measurements'. The radiation calculator estimates radiation levels at a chosen location from mobile phone masts within a 1,500-metre radius. It is unclear whether terrain or buildings are taken into account. However, the selected height above ground level does affect radiation intensity. This is because the intensity of the radiation increases when the height is level with the antennas.

Initially, the percentage of the limit value is displayed as parts per thousand for masts located within 1,500 metres. However, if you tap 'Avansert', you can increase the distance to 2,000 metres and change the height above ground level from the default of 1.8 metres. In cities, this can significantly impact radiation levels, as buildings block radiation from reaching the ground, while the top floor may have a clear line of sight to a mobile phone mast. Test this and allow for three metres per floor.

In 'Avansert' mode, the radiation intensity is displayed to five decimal places in watts per square metre (W/m²). This level of precision is sufficient to display radiation levels as low as 10 µW/m². One µW/m² is one millionth of a W/m², so 0.00001 W/m² means 10 µW/m².

The map works best if you start by selecting all the options. Then click the 'Vis' button.

Adresse: If no address is given, the whole of Denmark is assumed. This causes the map to load slowly if you then choose to view everything. 'Industrivej' is a good address to start.

Tjenestetyper: The meaning of 'Teknologineutrale tilladelser' is unclear. 'Andre' refers to FM radio, digital TV (DVB-T) and the railway's GSM-R, for example. To view mobile phone masts only, select 'Mobiltelefoni'. Selecting “Alle” allows you to make detailed selections under “Teknologier”.

Teknologier: If you selected 'Alle' under 'Tjenestyetyper', a wide range of options will be available and you can specify more precisely what you want to see. 'Radiokæde' means 'radio link', but none are displayed if this option is selected. 'Andre' only leads to a decommissioned long-wave and medium-wave radio mast (LW, MW). 'TV' refers to the decommissioned analogue TV network and no masts are displayed. 'DVB-T' shows masts for digital TV. 'Landmobile radiotjeneste' returns no results. According to Duck.ai, 'TK' is supposed to mean 'wireless network', but nothing is shown on the map.

Despite there being alternatives that show nothing, there are still plenty of mobile phone masts. Instead of 2G, 3G and 4G, the technical terms GSM, UMTS and LTE are used, respectively. 5G is referred to as 5G-NR. The technology and frequency used in each mast are shown. The frequency is indicated by an addition to the technical names GSM, UMTS, LTE and 5G-NR. For example, LTE1800 means 4G on the 1800 MHz frequency.

Adaptive antennas were first introduced with 5G technology. If this type of antenna is used in a mobile phone mast, this is indicated. The paths between radio links are shown, colour-coded by frequency. Mobile phone masts are named mobile phone base stations.

Mobile phone masts and other radio frequency transmitters are shown on a detailed map of Switzerland alongside other topics. Click on 'Change topic/Thema wechseln' to access additional useful information for residents and tourists.

These are all instructions needed because the Swiss mast map is the most user-friendly.

There is an instructional video showing everything that Cartoradio.fr has to offer. “Cartoradio, comment ça marche? Le tutoriel video”. The video ‘Simulations d'exposition, comment ça marche ? Le tutoriel video’ explains the background to the nationwide simulation of radiation levels. This video is available on YouTube and can therefore be translated into any language.

There is no need to fill in the address, postcode or town fields. Instead, you can select 'Sites radioélectriques' (masts), 'Mesures' (measurements) or 'Simulations' (simulations) directly. An English flag will then appear in the bottom left-hand corner. If you select English, the most important parts will be translated, but often not 'Faisceaux hertziens', which refers to radio link.

Start with ‘Configurer l'affichage’ (Configure display) and select what you want to see. Once the map has been zoomed in sufficiently, mobile phone masts and antenna directions will appear. Everything is colour-coded by mobile network provider.

The simulation shows estimated radiation levels, with the lowest reaching 0.4 volts per metre (V/m), equivalent to 424 microwatts per square metre (µW/m²). Therefore, the map showing the simulated levels does not indicate any areas with low radiation, even if such areas existed.

It's an ambitious measurement programme, but unfortunately the results are given in volts per metre. Due to constant changes to mobile networks, measurements are time-sensitive. By default, only measurements no older than two years are displayed. It is possible to change this setting to view older measurements. 4G was rolled out between 2010 and 2015, and 5G launched in most European countries in 2020.

The colourful map at the beginning does not show the intensity of radiation, but rather the number of mobile phone masts in a given area. Red indicates a high concentration of masts. Zooming in on the map makes individual masts visible. Clicking on them displays their exact location and the providers using them.

The link from en.vagbrytaren.se takes you directly to the mast map, and you can follow the instructions below. There are other maps and information on the same site.

Before clicking on the button containing an 'i' inside a circle, the masts are displayed as blue dots. However, no information appears when you click on them. Once the 'i' has been selected, information is displayed on the right-hand side of the page. To find all the information about the mast, open ‘Antennes émettrices stationnaires’ and ‘Localisations des sites’.

‘Resumé du site’ refers to the mast's exact location; ‘Type d'implantation’ indicates whether the antennas are mounted on a dedicated mast, water tower, church, power line pylon, building or is an indoor microcell.

‘Avis a priori’ opens a PDF document containing all the information that the provider has provided to the authorities. This includes frequency, antenna direction and whether it is an adaptive antenna (beamforming). Rather than using the terms 2G, 3G, 4G and 5G, the terms GSM, UMTS, LTE and 5G NR are used instead. The circles with the mast at the centre show the distances outdoors and indoors, respectively, within which the limit values may be exceeded. There are also many points around the mast showing the measured radiation level in volts per metre and relative to the limit value.

The masts are plotted on a map of Wallonia, alongside a wealth of other information. If you have lost the mast map but are still on the website, begin by selecting ‘Thèmes’ on the left-hand side of the page. Select 'L'industrie et les activités' and 'Cadastre des antennes émettrices stationnaires de Wallonie'. Next to 'Thèmes' is the 'Tables des matières' tab, where you should select both 'Antennes émettrices stationnaires' and 'Localisation des sites'.

The map of Flanders is covered in circles, each showing the number of masts within it. You can zoom in on the map by double-clicking or scrolling with the mouse wheel to see more details.

Clicking on a circle will display all the mast designations in the panel on the right. Clicking on a designation displays the provider and address. Further down is a 'Download' link that will take you to a PDF document containing all the technical details about the installation.

The PDF document contains two maps showing a mast surrounded by coloured 'bubbles'. These indicate areas where the radiation intensity may exceed limit values in places that are not normally accessed by people, such as rooftops. The map labelled 'Horizontal stralingspatroon (cumulatieve norm)' shows the risk zone calculated based on the combined limit for all transmitters. The map labelled 'Horizontaal stralingspatroon (norm per operator)' shows the risk zone calculated based on the limit for individual transmitters.

The combined limit for all transmitters is 2,500,000 microwatts per square metre. The limit for individual transmitters is 500,000 microwatts per square metre. The Zendantenneskaart is not mobile-friendly.

A green dot indicates a transmitter in operation with a power output of over 5 watts. In practice, this is usually a mobile phone mast with the permit 'Permis 1D octroyés'. A yellow dot indicates that a licence has been applied for. A red square indicates an FM radio station, listed in the information as 'Broadcast_' followed by the station's name. A blue triangle indicates a transmitter with a power output of less than 5 watts ('Permis 1C octroyés'), which may be a mobile phone mast located indoors. You can search by address; Rue de Trèves 3 is the entrance to the EU area. Clicking on a mast displays the provider’s name and links to further information on the right-hand side of the page.

‘Cliquez ici pour obtenir le permis d'environnement’ links to a PDF document in which you will find the transmitter power in dBm, the antenna gain in dBi, and the compass bearing in degrees (azimuth).

‘Cliquez ici pour accéder à la vue 3D des simulations ainsi paramètres techniques des antennes’ displays a three-dimensional simulation of the radiation pattern around the mast. You may need to deselect 'Carte au sol' to display the 'beams' in front of the antenna. Clicking on the 'beams' showing the direction of radiation from the antennas displays the system, power and antenna gain. ‘Accès aux diagrammes’ leads to detailed radiation patterns for the antennas.

The 3D simulation offers several options for displaying the radiation. 'Carte au sol' means at ground level; 'Carte façade outdoor' means on the exterior of the building; 'Carte façade indoor' means in the interior of the building; and 'Terrasses' means on the terraces. The 3D simulation corresponds to some extent to Norway's radiation calculator.

The indoor limit is lower than the outdoor limit: up to 499,200 microwatts per square metre (µW/m²), compared to up to 1,253,900 µW/m² outdoors.

In the 3D simulation, radiation level limits are expressed in volts per metre (V/m) and represent the total radiation from various frequencies, converted to the equivalent level for 900 megahertz (MHz). The lowest level (0–2.6 V/m) corresponds to 17,900 µW/m², while 9.19 V/m is equivalent to 224,300 µW/m², which is the indoor limit at 900 MHz. ZNAP stands for 'Zone Non Accessible au Public' and indicates that the limit has been exceeded. Please note that the ZNAP level is lower when 'Carte façade indoor' is selected, as the indoor limit is lower. The explanatory labels for indoor levels above ZNAP are not displayed. The image itself does not change.

Visitors will first see the measurement points, which are shown as yellow squares. The numbers inside the squares show how many measurements each square represents. Zoom in on the map to view the individual measurements and masts. Some measurements simply show the total radiation intensity, while others are broken down by frequency. A third type merely ensures that the limit values are not exceeded.

The date on which the measurement was taken is important because 4G was rolled out between 2010 and 2015, while 5G was launched in most European countries in 2020.

The transmitter power is stated only as dBW (decibel-watts) without the ERP suffix. The difference between dBW and dBW ERP is that dBW ERP is much higher and can be used to calculate how strong the radiation might be at various distances around the mast. However, dBW must first be converted to watts.

For some masts, the technical information is missing for unknown reasons.

The map shows mobile phone masts at a distance scale of 1 km. The information displayed for each mast varies from none at all to the vertical and horizontal distances at which the limit value is exceeded.

Measurements are carried out and the results are presented as a percentage of the limit values, as well as in bar charts. In these charts, the radiation level is shown in orange and the distance to the limit value is shown in green. Since one percent of the limit value can correspond to up to 0.1 watts per square metre (100,000 microwatts per square metre), the entire bar is always green, except for an orange strip at the bottom.

The percentage provides more detailed and accurate information when expressed to five decimal places. For example, 0.00207 per cent corresponds to a maximum of 207 microwatts per square metre (µW/m²).
Formula: 0.00207 ÷ 100 = 0.0000207 × maximum limit of 10,000,000 µW/m².
Therefore, 0.00001 per cent becomes 1 µW/m². Alternatively, you can move the decimal point five places to the right to get the same result.

The figures 'Bedingung (1+2)' refer to the frequency range of 1 Hz to 10 MHz. 'Bedingung (3+4)' refers to radio frequency radiation within the 100 kHz to 300 GHz frequency range, i.e. wireless technology and the right-hand bar in the diagram. Check the date when the measurement was taken. 4G was rolled out between 2010 and 2015, and 5G was launched in most European countries in 2020.

The map only shows 'Estación de Telefonía móvil', i.e. mobile phone masts. These are displayed at the highest and darkest levels on the zoom slider on the left. Initially, moving the zoom slider to the dark area will take you directly to Madrid. Use the panning buttons above the zoom slider or the mouse to pan.

The location of the masts on the map is not exact. The mast providers and address are displayed immediately when you click on a mast. After clicking on 'Detalle Ver' (View details), information on frequency, direction and readings in microwatts per square centimetre (µW/cm²) is displayed.

*There is no measurement programme. The measured values are presumably the provider’s checks to ensure that the limit values are not exceeded in areas closest to the mast that are accessible to the public. However, no description is provided. To convert microwatts per square centimetre (µW/cm²) to microwatts per square metre (µW/m²), multiply by 10,000.

The map of Austria is covered in circles, each showing the number of masts within it. Click on the circles or double-click on the map to zoom in and view the masts, or scroll with the mouse wheel. Blue dots represent mobile phone masts, purple dots represent radio and TV masts, and light blue dots represent measurement points.

‘Trägerstruktur’ describes how the antennas are mounted. 'Dach' means 'roof', 'Mast' means 'mast', and 'Fremdmast' can refer to a power line pole or another type of mast whose primary purpose is not to support antennas.

The power output of mobile service transmitters is specified in watts (W), whereas the power output of radio and TV transmitters is specified in watts ERP. The two methods of specifying transmitter power are not comparable because the power in watts is always lower than, or much lower than, the power in watts ERP for the same transmitter. Mixing these two methods without explanation, as has been done on Senderkataster.at, is misleading.

Measurements were taken in five rounds in 2007, 2009, 2012, 2017 and 2022. By 2017, 4G had been introduced, and 5G had been introduced by 2022. Although the Senderkaster.at website only reports on mobile communications, radio and TV were also measured. The report 'Mobilfunk – Messreihen' provides a total radio frequency radiation reading, enabling correct comparison of radio/TV and mobile service radiation at ground level. 'Mobilfunk – Messreihen' also provides background information and details of the technology.

Antennasearch
Antennasearch requires either an address or the name of a town. It then displays antennas within a 3-mile radius. Try entering 'N 13th St, Newark, NJ', a sprawling residential area to the west of New York. Blue dots indicate masts and red dots indicate antennas. You can choose to show either masts or antennas on the map.

Clicking on a marker will reveal further information in the list on the left-hand side of the screen. The owner is always listed, and if they are a mobile network provider, you can asume that the mast probably is a mobile phone mast. The three largest mobile network providers in the US are Verizon, T-Mobile and AT&T. There are also a number of local providers in individual states.

The location of each antenna is marked on an aerial photograph. Apple provides Antennasearch with the maps and images.

The Sitefinder map was last updated in May 2012, after all providers ceased cooperating with Ofcom. At that time, it contained details of 144,317 base stations, which were distributed across an unknown number of mobile phone masts. The data set with the 144,317 base stations is free to use.

Read more about the Sitefinder Map and its epilogue.

The circles show the number of masts within each circle. Click on the circles or zoom in on the map to display blue symbols for the masts and green ones for the measurement points. Instead of 2G, 3G and 4G, the technical terms GSM, UMTS and LTE are used. 5G is not called 5G or 5G-NR, but simply NR. You can find the exact location of the masts, specified in the Irish grid reference system and as latitude and longitude.

Items to be displayed can be selected from the menu in the top right-hand corner. Measurement points must be found on the map and cannot be selected. If you have chosen to view radio links, also known as fixed links, the narrow link path to the other radio link with which communication is being established is displayed, but only after you have opened and closed the window containing the detailed information. The compass heading in degrees is never displayed.

The measurement programme reports field strength in volts per metre (V/m), both as a total and broken down by frequency for each technology.

To view any masts, you will need to enter either an address or a town. Sydney works well. A list of base stations will appear. Click on the 'Map' tab to start exploring the city. Blue circles indicate the number of masts within them. You can then zoom in or click on a circle. The exact location of the masts is shown, given as a latitude and longitude as well as a street address. You will also be informed whether the antenna is mounted on a lamppost, roof, or is freestanding or indoors. And, of course, all providers that use the mast.

Click on the seven-digit number at the top of the information panel to display the frequencies. All other masts on the map will disappear at the same time. Tick the 'Nearby sites' check box to make them reappear. Details about a mast may also include an 'ARPANSA EME Report', which provides a theoretical calculation of the radiation around the mast. You can enter your email address for each mast to receive a notification if anything changes.

The map is managed by the Australian Mobile Telecommunications Association (AMTA), which represents Australia's three mobile network providers.
