How do airtags update location

In today’s world, staying connected with our valuable possessions has become more critical than ever. Whether it’s our keys, wallets, or even pets, keeping track of their whereabouts can sometimes be daunting. However, Apple has introduced an innovative solution to address this problem – AirTags. 

These tiny, coin-shaped devices leverage advanced technology to update their location and enable users to locate their belongings easily. In this blog post, we will delve into the fascinating world of AirTags and explore how they update their location.

What are AirTags?

AirTags are small, coin-shaped devices designed by Apple that use Bluetooth technology to connect and sync with your Apple devices. They are specifically designed to help users locate and track their belongings with the utmost convenience.

How Do AirTags Work?

AirTags use Bluetooth, ultra-wideband (UWB) technology and Apple’s vast network of devices to update their location accurately. Let’s take a closer look at each aspect:

  • Bluetooth Technology: AirTags uses Bluetooth Low Energy (BLE) to communicate with nearby Apple devices, such as iPhones, iPads, and Macs. It allows them to connect and share data, including location information.
  • Ultra-Wideband (UWB) Technology: AirTags are equipped with UWB technology, which enables precise spatial awareness. UWB uses short-range radio waves to measure the distance between devices accurately. By leveraging UWB, AirTags can precisely locate items with your iPhone, helping you pinpoint their exact location.
  • Apple’s Network of Devices: One of the most remarkable features of AirTags is their ability to leverage Apple’s extensive network of devices. When an AirTag is near another Apple device, it can transmit its location securely and anonymously to the owner via the Find My app. This network effect greatly enhances the chances of locating lost items, as the collective power of millions of Apple devices contributes to the search.

Location Updates: Step-by-Step Process

Now that we understand the underlying technologies let’s explore the step-by-step process of how AirTags update their location:

  1. Initial Pairing: To use an AirTag, it must be paired with an Apple device. It is done by bringing the AirTag close to the device and following the pairing instructions on the screen. Once paired, the AirTag is associated with the owner’s Apple ID.
  2. Bluetooth Connection: AirTags establish a low-power Bluetooth connection with nearby Apple devices like iPhones. When in range, the AirTag periodically sends Bluetooth signals to notify nearby devices of its presence.
  3. Location Detection: When an Apple device picks up the AirTag’s Bluetooth signal, it records the AirTag’s location along with a timestamp. This information is encrypted and securely stored on the device.
  4. Data Upload: As the Apple device moves within range of the internet, it uploads the encrypted location data to Apple’s servers. It happens automatically in the background, without any intervention from the user.
  5. Find My App: The AirTag owner can access the location information through the Find My app on their Apple device. The app consolidates data from various sources, including the owner’s device and other Apple devices near the AirTag, to provide the most accurate location updates.


AirTags revolutionize how we keep track of our belongings, offering a seamless and efficient solution. By combining Bluetooth technology, ultra-wideband technology, and Apple’s vast network of devices, AirTags update their location accurately, ensuring you always keep sight of what matters most. With their remarkable features and commitment to privacy, AirTags has become an indispensable tool for tech-savvy individuals seeking peace of mind in their daily lives.


Can AirTags update their location without an internet connection?

While AirTags themselves do not have a direct internet connection, they rely on nearby Apple devices with an internet connection to update their location data. The collective network of Apple devices plays a crucial role in providing accurate location updates.

How frequently do AirTags update their location?

The frequency of location updates can vary based on various factors, such as proximity to Apple devices and network availability. However, AirTags can update their location in ideal conditions every few minutes.

Are AirTags secure and private?

Apple has implemented several security measures to protect user privacy. AirTags uses end-to-end encryption to secure the location data transmitted between devices, and location updates are anonymized to prevent tracking of individuals.

Apple has implemented strict measures to prevent AirTags from being used for tracking individuals without their knowledge. If an AirTag is detected to be travelling with someone who does not own it, the owner will receive an alert on their device.
