This SP system is the single panel transceiver. The system functions in nearly the same way as the standard RF systems, but at a wider aisle width and requires only one antenna to operate. This system can detect tags with 5 feet (152.4 cm) on either side of a single panel and if two panels are used, an opening as wide as 20 feet (6.09m) can be protected. Another advantage of the single panel system is that the electronics do not have to be synchronized, which minimizes installation time and after sales service.
