Process steps:

At first, guests call the reception desk that he need to active or 

lock the in-room safes and then the manager of hotel will input 

the corresponding dictate in the PC. These indications will be 

transmitted to "Data transceiver" by serial port or net port. 



The data processed will be transmitted to mini wireless projector 

and then coded and modulated frequency modulation to transmit 

to antenna. 



The antenna transmits signals, meanwhile, the wireless module 

of safes will receive them by a small antenna connected to main 

chip. After reconciliated, data will be transmitted to mini-control on 

the PCB and then safes start to executive command. 



Features:

All the data transmitted will be encrypted and unencrypted by 

special technology to avoid other people to head off intentionally. 

The whole module has very high reliability and security. 



Effect range is wide and the distance that data can transmitted is 

very far. If power of emission is amplified, the range can be beyond 

30 kilometers, even further. 



Adopting whole set installation without debug phase, easy 

application.
