Radio Frequency Tracker

Radio frequency pet tracker

RFID is a tracking solution that employs intelligent bar codes to track objects. The acronym stands for Radio Frequency Identification. The automatic technology uses electromagnetic fields or radio waves. These fields identify and track information stored in tags attached to items. Tiny miracles of miniaturization, these RFID chips (Radio Frequency IDentification chips) measure just 0.05 x 0.05 millimeters. 'RFID' refers to small electronic devices that use a tiny antenna to. Marco Polo is a radio frequency pet tracking system that updates your pet’s location information every few seconds and boasts a 2-mile communication range. The device is accurate within inches. Easy indoor and outdoor tracking in any corner of the world Quick.

Radio Frequency Beacon Tracker

Sep 07, 2018 Other models have upper frequencies of 12 and 18 GHz. Aaronia is also unique in that they’ve developed a drone detection system comprised of a 3D tracking antenna, the model IsoLOG 3D with options from 9 kHz to 40 GHz in 360 degrees. This matches up with their Spectran Command Center with triple LCD screens. Radio frequency identification devices are a daily part of the electronic age, and are fast becoming a part of passports and payment cards and are widely expected to replace bar-code labels on.
