2.4GHz Wireless Access Control System
1. Cost benefits
Wireless communications can significantly reduce the use of cable to each machine using 50 m average wire basis, the annual sales of 1 million devices to save 500, 000 m cable, if you use five lines, then save more than 100 million cable costs; If 10 RMB per meter wiring costs, the savings of more than 500 million of the wiring costs. Conservation-oriented society in nation-building policy, the popularity of wireless smart card device has obvious social benefits.
Compared with the existing technology:
wireless TCP/IP RS485

Maximum transmission distance Radius of 1 km 90m 1200m
Network capacity 60000 According to the switch port 127
Barriers across the ability Able Inability Inability
Cable consumption nothing higher general
Anti-jamming capability strength Weak strength
The initial construction costs Lower High Medium
2. Contractors using advantages
1) Removed from communications wire and related construction costs
2) Shorter construction time, reduce labor costs
3) Maintenance is simple, do not check the lines, through the management software can find the problem.
4) Software is very user-friendly, it's easy to use, and the manufacturers also provide personnel on-site training services, system functions can be modified by the owner required to fully meet the construction needs
5) System installation process eliminates the need for a large number of connections and ports, to reduce problems such as bad, manufacturers provide product warranty for two years.
6) No longer worry about the decoration of the scene, whether newly installed or equipment replacement projects to upgrade project, replacing a large number of on-site construction problems.
7) Facilitate the migration of the late increase in equipment and equipment
3. User advantages
1) Installation is simple; The decoration does not destroy the environment.
2) Construction time is short, does not affect the normal working hours
3) System more stable, more secure data
4) Facilitate the migration of the late increase in equipment and equipment
5) Easier system maintenance, manufacturers can extend the time for maintenance-free
