Marathon Timing Solution Mat Antennas and E710-Based Fixed Readers

SEEMORE IOT Launches Next-Generation Marathon Timing Solution Featuring Circularly Polarized Mat Antennas and E710-Based Fixed Readers

SEEMORE IOT, a specialist in RFID hardware development, today announced the launch of its next-generation marathon timing solution for road racing events. Built around fixed readers powered by Impinj's latest E710 chip and proprietary circularly polarized carpet antennas, the solution delivers millisecond-accurate timing, real-time tracking, and anti-cheat assurance for race organizers.

Core Technology: AN Circularly Polarized Carpet Antenna

The mat antenna features an FR4-acrylic-FR4 composite structure and circular polarization design. At just 8 mm thick, it withstands heavy vehicle pressure. Its low-backward radiation characteristic effectively reduces multipath interference, ensuring high read rates in dense crowds. With an axial ratio below 3 dB (860-920 MHz) and IP67 waterproof encapsulation, it operates reliably in extreme weather, from heavy rain to high temperatures.

High-Performance Fixed Reader:

The fixed reader, powered by the Impinj E710 chip, supports EPC Gen2v2 and Gen2X protocols and processes over 400 tags per second. Its 4-antenna port design flexibly connects multiple carpet antennas for large-scale deployment at start lines, split points, and finish lines. With PoE support and Ethernet communication, it seamlessly integrates into central race timing systems.

Comprehensive Tag Product Line

SEEMORE IOT also introduces a tag series tailored for marathon applications:

• Bib Tag: Disposable, based on Impinj M830 chip with Gen2X support, cost-optimized for large-scale procurement.

• Shoe Tag: Reusable, waterproof, and crush-resistant—ideal for series events or rental models.

• Ankle Tag: Designed for elite races requiring stable reads, secured around the ankle to minimize movement interference.

Success Story: Precision Timing at University Events

The solution has been successfully piloted at Sichuan Agricultural University's sports meet and several city fun runs. According to university feedback, the system completely resolved missed and incorrect records associated with manual timing, improving accuracy to within 0.8 seconds and providing real-time split queries for thousands of runners.
