4 de dic. de 2023 · UHF RFID systems use frequencies in the 860-960 MHz range and can be used to detect as many as 1,000+ tags per second as far as 10-15 meters from the reader, making them ideal for wide and busy finish lines where several tagged participants may be crossing in a short space of time.
2 de dic. de 2015 · The UHF RFID antenna we use, which is from the same family as the Impinj antenna, is a slot antenna with a cavity. The slot is where the signal enters very close to it and cuts the flow of the current.
16 de ene. de 2020 · After extensive testing, we’ve determined that the Impinj RFID readers are most suitable for race timing. While Webscorer PRO can be used with any reader that supports the industry standard LLRP protocol, only the Impinj readers switch power between multiple antennas quickly enough to achieve high chip read rates.
1 de ago. de 2018 · The Gen2 RFID standard is the one used by almost all manufacturers of timing technology: timingsense, MyLaps, RaceResult, Chronotrack, Macsha, Ipico… In Europe GEN2 consists of 15 channels, but a reader can only broadcast on 4 at maximum power .
RFID Race Timing has developed an antenna mat system, which is modular, easy to setup and specifically designed to meet the requirements of sporting events. The ULTRAMAT antennas are sealed within low profile mats developing maximum sensitivity within the” read zone”. Each mat is 1m wide and interlocks to create finish lines of up to 16m wide.
26 de ago. de 2022 · A timing system that measures the change in phase of an active electromagnetic signal to determine the position of the chip. This system is more accurate (about an order of magnitude better) than RSSI systems, and is thus common in motor-sport and other races where high-accuracy of lap/finish times is important.
20 de dic. de 2013 · “We use timing mats with linear threshold antennas that are low profile so that they fit inside our mats,” he explains. “We also use circular antennas at the finish to pick up tags that are no longer in a vertical position, since our linear antennas are polarized and are looking for vertical tags.”
