Is There a Long-Range RFID System That I Can Install in Indoor Facilities?

Posted By RFID Journal, 01.06.2014

If so, can it detect products located 50 to 100 meters (164 to 328 feet) away?

Active RFID systems can typically read tags from a distance of 300 meters (984 feet) or more, because active tags broadcast a signal, like a cell phone. Active real-time location system (RTLS) technology can tell you the location of a tagged object within 10 feet or so, though some systems have a greater level of accuracy. Active tags typically cost $50 and up, so if you are tagging inexpensive products, an active system is unlikely to be cost-effective.

Mojix offers a phased-array antenna system that can locate tags from more than 100 meters away. This solution is often described as a passive real-time location system. If you are tagging multiple items, this could be a more cost-effective solution for you, since the Mojix system reads ordinary, passive ultrahigh-frequency (UHF) tags.
