The Cell Broadcasting System (CBS) is a technology that allows emergency or public service messages to be sent to all or specific cell phone users within a defined geographical area. It is commonly used by government agencies or mobile network operators to broadcast important information such as severe weather alerts, natural disasters, public safety announcements, or other critical notifications.
CBS operates on a cell broadcast channel that is separate from regular voice and data communication channels. When an emergency message is broadcasted, cell phones in the targeted area receive the message and notify the user, even if they are not actively using their phones.
This technology is a powerful tool in providing immediate and widespread information to the public during emergencies, helping to ensure the safety and well-being of individuals in affected areas.
Please note that the availability and implementation of the Cell Broadcasting System may vary across different countries and mobile network providers.
If you hear a scary alert on your cell phone – and everyone else’s cell phone – at 12:23 -13:00 PM IST on Friday, October 6, 2023, don’t panic.
On Thursday afternoon, October 5, 2023, the federal government said it would conduct a nationwide test of its Emergency Alert System and wireless emergency alerts. The EAS portion of the test will send an emergency alert to all radios and televisions, while the WEA portion of the test will direct the alert to all consumer cell phones.
Advice: Department of Telecommunications, Government of India is testing cell broadcast with NDMA. You may receive test messages on mobile with sound/vibration. These messages are part of the testing process, not indicative of a true emergency. These do not require any action from your side.
Subsequently, on Friday, October 6, 2023, at approximately 12:23 -13:00 PM IST, all wireless phones received an alert and a text message:
The free text message will be sent in English or another language depending on your device’s language settings. FEMA said the text will have a unique tone and vibration, intended to make the alerts accessible to the entire public.
The test was broadcast by cell towers for about 30 minutes from 12:23 pm to 13:00 pm IST. During this time, all compatible wireless phones that are turned on within range of an active cell tower, and whose wireless providers participate in WEA tests, should receive text messages.
Meanwhile, all radios and televisions will also broadcast a test emergency warning at the same time as part of the widespread testing. The message, lasting about a minute, would say: “This is a nationwide test of the emergency alert system issued by the Federal Emergency Management Agency.”

How government sends Cell Broadcasting System (CBS) alerts?
The government sends Cell Broadcasting System (CBS) alerts through the cell broadcast channel, which is separate from regular voice and data communication channels. Here is a general overview of how the government sends CBS alerts:
Government Authority: The government agency responsible for issuing emergency or public service messages determines when and what information needs to be broadcasted through the CBS.
Emergency Message Creation: The government agency creates the emergency message that is intended to be sent to cell phone users. This message typically contains important information such as severe weather alerts, natural disasters, public safety announcements, or other critical notifications.
Geographical Area Selection: The government agency determines the geographical area where the CBS alerts need to be broadcasted. This can be a specific location, a region, or even nationwide, depending on the nature and scale of the emergency or public service message.
Cell Broadcasting Center (CBC): The government agency or a designated authority operates the Cell Broadcasting Center (CBC). This is the central hub that manages the sending of CBS alerts. The CBC is usually connected to the cellular network infrastructure.
Alert Distribution: The government agency uses the CBC to distribute the emergency message to the relevant cell phone users within the defined geographical area. The CBC sends the CBS alert using a cell broadcast technology, which allows the message to reach all compatible cell phones within the targeted area.
Broadcast Activation: The government agency activates the CBS alert broadcast, instructing the CBC to send out the message. The alert is broadcasted on the cell broadcast channel, and cell phones within the targeted area automatically receive the message.
Cell Phone Notification: When a cell phone receives a CBS alert, it triggers a notification on the user’s device, even if they are not actively using their phones. The notification typically includes information about the type of alert and instructions on what actions to take.
It’s important to note that the exact process and technical implementation of the CBS may vary across different countries and mobile network operators. Additionally, government agencies may have specific protocols and procedures in place for sending CBS alerts during different types of emergencies.
Cell Broadcasting System (CBS) alerts Purpose
Cell Broadcasting System (CBS) alerts are designed to provide important and timely information to the public during emergencies. They serve as a critical tool for disseminating severe weather alerts, natural disaster warnings, public safety announcements, and other critical notifications.
CBS alerts themselves are not inherently harmful. They are intended to help ensure the safety and well-being of individuals in affected areas by providing immediate and widespread information. When a CBS alert is broadcasted, cell phones within the targeted geographical area receive the message and notify the user, even if they are not actively using their phones.
However, it’s worth noting that CBS alerts can be alarming or disruptive due to their nature and the urgency with which they are sent. They are designed to capture the attention of the user and convey important information during emergency situations. As a result, CBS alerts may startle or surprise individuals, especially if they are received during unexpected times.
It’s important to understand that CBS alerts are intended to be helpful, and their purpose is to provide critical information in a timely manner. The impact of CBS alerts largely depends on the content of the messages and the context in which they are received.

CBS Alerts can increase electromagnetic radiation?
The Cell Broadcasting System (CBS) alerts themselves do not emit any form of radiation. CBS is a technology that allows emergency or public service messages to be sent to all or specific cell phone users within a defined geographical area. It operates on a separate channel from regular voice and data communication channels.
However, cell phones, like any electronic devices, emit a small amount of electromagnetic radiation while they are in use. This radiation is emitted in the form of radio waves and is necessary for the device to communicate with cellular towers and other devices. The radiation emitted by cell phones is classified as non-ionizing radiation, which means it does not have enough energy to ionize atoms or molecules, unlike ionizing radiation such as X-rays or gamma rays.
It’s important to note that numerous scientific studies have been conducted to understand the potential health effects of electromagnetic radiation emitted by cell phones. Currently, the consensus among international health organizations, such as the World Health Organization (WHO), is that there is no conclusive evidence to support a direct link between cell phone radiation and adverse health effects.
To minimize exposure to electromagnetic radiation from cell phones, some tips include:
- Use a hands-free device or speakerphone when making calls.
- Limit the duration of your phone calls.
- Keep your cell phone away from your body, such as in a bag or using a belt clip.
- Use text messages or messaging apps instead of making lengthy voice calls.
- When not in use, place your cell phone in airplane mode or turn it off.
It’s always a good idea to stay informed about the latest research and guidelines regarding cell phone radiation and to follow the recommendations provided by health authorities in your country.
