What is RFID?
RFID Ultra UHF System
NEW to market early February 2010.
The disposible system works using UHF technology.
We are pleased to announce the arrival of RFID Ultra, the latest offering from RFID Race Timing Systems. Put simply, Ultra is a Ultra High Frequency RFID system using the latest Generation 2 UHF protocols, high sensitivity readers, specialised in-house antennas and Battery Assisted Passive (BAP) tags and now passive UHF tags from multiple suppliers around the world. Ultra consists of 3 superior components;
The Reader Box – Contains the RFID reader, networking hardware and industrial computer. The control box is a small heavy duty case that is designed for work in the worst outdoor conditions. With 8 or 4 antenna ports, one control box can drive 8 or 4 antennas to cover a 9 or 4.5m wide timing point. The UHF reader inside is currently the world’s most sensitive Gen2 reader with a maximum receive sensitivity of -80dBm. With some antennas we have achieved a read range of up to 70m using the BAP tag.
Proprietary Antennas – RFID Race Timing has developed their own UHF patch antennas specifically for sports timing. These antennas have maximum sensitivity to the BAP tags whilst minimising unwanted reads flanking the read zone. The antennas are currently embedded in a flexible EVA mat that is easy to position in many configurations. Each mat piece measures 1.1m wide by 0.45m deep and weigh’s 2.5kg. The antenna mats are extremely thin at just 11mm (0.4 inches) high thereby avoiding issues with athletes tripping on a thick and bulky antenna section.
BAPs – Until now UHF tags have had problems being read on the human body. Alot of events have tried to address this by placing the transponder off the human body using elaborate tags on the shoe lace – a system that requires input from the competitor and is not ‘idiot proof’. All passive tags are severely compromised when placed very close to the human body due to detuning and loss of backscatter signal. Enter the Battery Assisted Passive or BAP tag. These tags use an ultra thin liquid battery that powers the onboard RFID chip leaving maximum energy backscatter to the reader. The tags are also specifically designed to be read next to the skin and tuned accordingly. The performance gains are remarkable for what is essentially still a passive tag that can be produced at low cost (unlike an active tag that uses a coin battery cell). The battery is non-toxic and has been cleared for safe disposal by the most stringent of environmental rules imposed in Europe.
The beauty of the BAP is that it can be worn on the back of the chest race number completely eliminating the need for the competitor to perform fiddly manoeuvres with an adhesive label on their shoe. This really is the ultimate system for timing large running events throughout the world.
