1. Installation without cables
2. Real-time online system
3. Batteries powered

Working Principles:
The communication system contains two parts: Wireless network and wired network. WRFLock communicates with WNB and WAP through wireless signals. Host computer communicates with WAP through wired Ethernet LAN. Normally one wireless network is Constituted on each floor, where there are many WRFLocks, one WAP and some WNBs. Wireless network is created by WAP. WNB and WRFLocks connected with WAP nearby automatically.

Features:
1) No cables needed when installing door lock. It works with 4 AA alkaline batteries.
2) Up to 20m (65') effective communication distance between WAP and WRFLock.
3) It adopts MIFARE contactless smart card of PHILIPS Company in Holland. It has advanced high performance and dependability.
4) Monitoring and recording all operations by host computer in real-time
5) Detecting wireless signal intensity by host computer, So that the system installation and commissioning is simple.
6) Low voltage detecting and alerting by host computer, So that the easy system maintenance is easy.
7) FLASH storage technology. Parameters info, card info, and records of all door locks can be saved in FLASH. Even when power supply is cut off, no data will be lost.
8) Multiple door locks can be open by only one card. Multiple cards (Maximum 64 PCS) can open one door lock.
9) Opening Interface. Thus, you can realize the connection with all kinds of hotel management systems and realize the multi-purpose smart card management.
