Apple AirTag First Findings: Location Tracking Tested

Apple AirTag Initial Impressions

After several hours of use, Apple’s new AirTag location devices appear to function as expected. The initial setup process is straightforward and intuitive, clearly mirroring the design Apple implemented for its AirPods.

Precision Finding and Bluetooth Technology

The precision finding capability, powered by the U1 chip, serves as a compelling demonstration of practical augmented reality. A virtual arrow and other visual cues are displayed on the screen, facilitating quicker tag location.

For those unfamiliar, AirTags utilize Bluetooth beaconing to broadcast their presence to nearby devices running iOS 13 or later. These signals are encrypted and generally imperceptible to bystanders, particularly when in the vicinity of their owner.

Importantly, the device that detects an AirTag’s location remains anonymous, even to Apple itself. This ensures user privacy throughout the location process.

Range and Accuracy

Proximity to a device logged into the iCloud account associated with the AirTags is a key factor. Typical Bluetooth range is approximately 40 feet, though this can vary based on environmental conditions and signal reflection.

Initial testing indicates that AirTag location range aligns with standard Bluetooth expectations. Obstructions, walls, or unfavorable signal conditions can impede performance.

In one instance, obtaining an initial location from an AirTag in another room took over 30 seconds. However, once a location was established, directional guidance proved remarkably accurate, pinpointing the tag within inches.

Battery Life and Design

AirTags are powered by a standard CR2032 battery, which is easily replaceable by the user. They also offer a degree of water resistance, including the ability to withstand brief submersion.

A variety of accessories are available, including leather straps for bags, luggage tags, and key rings, all appearing thoughtfully designed.

Notably, this location functionality is not currently integrated into the latest Apple TV remote.

Internal Hardware

A look inside the disassembled AirTag reveals Apple’s dedication to hardware refinement. The battery contacts are not simple spring prongs, as is common in small devices.

Instead, contact is established through the internal casing and a series of pressure points. This design should enhance durability and maintain reliable connection during battery replacements.

Initial results are promising, with further testing planned.

Safeguarding User Privacy with AirTags

When considering location-based technologies, security and privacy are paramount concerns for AirTags, and Apple has implemented several protective measures.

AirTags are designed for individual ownership and cannot be readily shared between users. While members of an iCloud Family Sharing Group can indefinitely silence “unknown AirTag nearby” notifications, AirTags won’t appear alongside other iOS devices within the standard Find My section. Instead, a dedicated “Items” section has been created within the app to manage these devices.

Further privacy enhancements include a warning system that activates after a period of time if an AirTag is detected in close proximity to someone who is not its registered owner – potentially indicating it is traveling with them unnoticed. Users can then choose to have the tag emit a sound for location, view its identifying information, or deactivate it by removing the battery. 

An AirTag separated from its owner for an extended duration – currently set at 3 days, but subject to adjustment by Apple based on usage patterns – will begin to audibly signal its presence whenever it is moved. This feature serves to alert individuals to its location. 

Users also have the option to activate Lost Mode, allowing them to share contact details with anyone who discovers the AirTag. This information is accessible via NFC technology on any smartphone, including Android devices, simply by tapping the device against the tag. Alternatively, only a serial number can be displayed if the user prefers not to share personal information.

This functionality specifically addresses scenarios where an individual does not possess an iOS device to receive alerts about a nearby, unfamiliar AirTag. The tag will eventually emit a sound even if it isn’t in Lost Mode, regardless of the owner’s control.

Apple has proactively considered numerous potential use cases, though unforeseen situations may arise as AirTags become more widely adopted.

Apple possesses several key advantages in this market:

• A vast network of approximately one billion devices worldwide capable of assisting in locating an AirTag.
• Integration of a U1 wideband chip, enabling precise location accuracy (within inches) when paired with a compatible U1-equipped iPhone.
• A comprehensive suite of privacy features not currently found in competing tracking tags.

Notably, Apple has announced plans to release a specification for chipset manufacturers this Spring, granting third-party devices with Ultra Wideband radios access to the U1 chip functionality present in iPhones. This will enable similar Precision Finding capabilities in accessories lacking a built-in U1 chip, like AirTags. Furthermore, Apple has extended access to its Find My network to third-party devices from companies such as Belkin, Chipolo, and VanMoof, allowing them to offer comparable basic finding functionality. Tile has also revealed intentions to launch a UWB-enabled tracker, while simultaneously voicing concerns to Congress regarding Apple’s market dominance. 

The real-world performance of these features will become clearer as AirTags are deployed and subjected to various conditions. Initial testing has been limited, with the devices only being available for less than 12 hours, preventing thorough evaluation of edge cases and practical utility in public environments. 

The devices will be available for purchase starting April 23rd.
