iBeacon vs Eddystone

iBeacon vs Eddystone: A Comprehensive Comparison

iBeacon and Eddystone are the two dominant BLE beacon advertising formats, each defining how a beacon device structures its advertising packet payload to convey its identity to nearby scanners. iBeacon is Apple's proprietary format; Eddystone is Google's open-source format. Both run on identical BLE hardware but differ in packet structure, data richness, ecosystem integration, and use case focus.

Overview

iBeacon was introduced by Apple at WWDC 2013 and built into iOS 7. It defines a simple 20-byte payload embedded in the BLE manufacturer-specific advertising data field. The payload contains a 128-bit ATT">UUID (identifying the beacon network), a 16-bit Major value (identifying a group within the network), a 16-bit Minor value (identifying the individual beacon), and a 1-byte measured TX power calibration value for RSSI-based distance estimation. iBeacon's design is intentionally minimal — it encodes identity, not content.

Eddystone was released by Google in July 2015 as an open-source specification. Unlike iBeacon's single packet format, Eddystone defines three primary frame types: Eddystone-UID (similar to iBeacon — a namespace + instance identifier), Eddystone-URL (broadcasts a compressed URL directly in the advertising packet), and Eddystone-TLM (Telemetry — broadcasts battery voltage, temperature, and uptime). Eddystone uses the BLE Service UUID field (0xFEAA) rather than manufacturer-specific data, making it easier to parse on any platform.

Key Differences

• Frame variety: iBeacon has one frame type; Eddystone has three (UID, URL, TLM) with an optional EID (Ephemeral Identifier) for secure deployments.
• URL broadcasting: Eddystone-URL can encode a full web URL (compressed with standard expansions) directly in the advertising packet — enabling "Physical Web" interactions where a phone displays a relevant link without any app. iBeacon cannot broadcast a URL.
• Telemetry: Eddystone-TLM enables a beacon to broadcast battery level, temperature, and packet count — enabling infrastructure monitoring of beacon health. iBeacon has no equivalent.
• Ephemeral IDs: Eddystone-EID broadcasts a rotating 8-byte identifier derived from a shared secret and time, making the beacon identifiable only to authorized resolvers. This prevents unauthorized tracking of specific beacons. iBeacon's UUID/Major/Minor is static and publicly visible.
• Platform ecosystem: iBeacon is native to iOS Core Location framework — background ranging, region monitoring, and local notifications work without any SDK. Android requires third-party libraries (AltBeacon, Kontakt SDK) for iBeacon. Eddystone is natively supported by Android (Nearby API) and requires libraries on iOS.
• Open vs. proprietary: Eddystone is fully open source (GitHub: google/eddystone); iBeacon requires iOS Developer Program membership and Apple's licensing terms.
• Interleaved frames: An Eddystone beacon can broadcast multiple frame types in rotation (e.g., alternating UID and TLM frames), providing both identity and telemetry from a single device. iBeacon can only broadcast its single frame type.

Technical Comparison

Use Cases

When iBeacon Excels

• iOS-first retail and hospitality: If the target user base is predominantly iPhone users and the deployment relies on iOS native features (region monitoring, local notifications, Core Location background behavior), iBeacon's deep iOS integration eliminates SDK dependencies and enables reliable background triggering.
• Simple proximity triggers: Push notifications when a user enters a store zone, in-store navigation prompts, and loyalty program check-ins that need only UUID/Major/Minor for location logic are well-served by iBeacon's simplicity.
• Existing Apple ecosystem infrastructure: Venues that have already standardized on Apple's iBeacon ecosystem (Estimote, Kontakt, Gimbal hardware configured as iBeacons) benefit from consistency and the established deployment patterns.

When Eddystone Excels

• Physical Web / URL broadcasting: Museums, art galleries, product displays, and public information kiosks benefit from Eddystone-URL's ability to surface relevant web content on Android devices without requiring an app or pairing — the user's phone displays a GATT & ATT">notification linking to a URL encoded directly in the advertising packet.
• Infrastructure health monitoring: Large beacon deployments (airports, malls, stadiums) benefit from Eddystone-TLM's battery and temperature telemetry, enabling proactive replacement of low-battery beacons and environmental monitoring.
• Secure enterprise deployments: Eddystone-EID's rotating identifier prevents unauthorized parties from tracking beacon infrastructure or spoofing beacon identity — important in healthcare, government, and financial deployments.
• Cross-platform (iOS + Android) deployments: Eddystone's open specification and native Android support reduce SDK complexity in mixed-OS environments.
• Rich data broadcasting: Deployments that need to broadcast both identity (UID) and operational metadata (TLM) from a single beacon device benefit from Eddystone's multi-frame architecture.

When to Choose Each

Choose iBeacon when: - The user base is predominantly iOS and native Core Location background monitoring is required - The use case is purely proximity-based (zone entry/exit triggers) with no telemetry requirement - The ecosystem (hardware, CMS, analytics) is already built around iBeacon

Choose Eddystone when: - Cross-platform iOS + Android support with a single open format is required - URL broadcasting to Android Nearby notifications is part of the user experience - Beacon infrastructure health monitoring via TLM is a deployment requirement - Security requires rotating identifiers (EID) to prevent unauthorized tracking - The specification must be fully open for audit or procurement compliance

Practical reality: Many production beacon deployments configure hardware to broadcast both iBeacon and Eddystone-UID frames by rotating between them in the advertising interval. Most enterprise beacon hardware (Kontakt, Estimote, Minew) supports simultaneous multi-format broadcasting.

Conclusion

iBeacon and Eddystone solve the same fundamental problem — how to structure a BLE advertising packet so nearby devices can identify a beacon — but with different philosophies. iBeacon is minimal, iOS-native, and optimized for the simplest proximity use case. Eddystone is richer, open, and platform-agnostic, with URL broadcasting, telemetry, and rotating identifiers that address real enterprise deployment needs. For new deployments, Eddystone's openness, telemetry capability, and Android-native support generally make it the more versatile choice; iBeacon's iOS native Core Location integration remains compelling for iOS-first applications.
