RTLS (Realtime Location System)

Currently LPM Technology adopts ultrasonic technology for fine ranging. Ultrasonic technology is an accurate and cost-effective ranging solution compared with other technologies like WiFi, UWB (Ultra-wideband). Ultrasound cannot pass through solid walls, which avoids interferences among adjacent systems. So this technology is well suited for restricted area such as stages. RF technologies may be good choices for wide and partitioned area. LPM Technology is providing locating technology using CSS (Chirp Spread Spectrum) in addition to ultrasound.
