IPICO’s Dual Frequency products offer the same ability as low frequency RF systems for operating tags in lossy mediums, and the same high data rates as those offered by UHF systems. The Dual Frequency operating frequencies are such that tags are not screened by human bodies, conducting liquids, etc. Compared with other low frequency technologies, much longer reading ranges can be achieved, mainly because the return link (Tag to Reader) operates at 6.8MHz, which is much higher than the forward link (for powering the Tag), which operates at 125 kHz. These products employ the robust IP-X TM anti-collision algorithm, allowing up to 120 tags to be read simultaneously, at a rate of up to 30 tags/s. It handles dynamic tag populations extremely well; the Reader does not have to complete reading a group before new tags are added.
The technology is ideal for tracking people, animals, documents and paper rolls.
The Short Range Dual Frequency Reader has a dual integrated loop antenna system, and can operate as a single unit (linked to a PC, DIMI, or other control device), or in conjunction with a second unit to span a portal, turnstile, or other fairly narrow aperture (<0.8m). For wider coverage, the Medium or Long Range Readers are available. When two Readers are operated together, the Reader connected to the PC is the “Master” unit, while the second Reader is the “Slave”. The Master controls the Slave Reader, receives its tag data, which it sends to the PC or DIMI together with its own received tag data.
Key Features
