Communication system

Wireless WiFi communication subsystem

   This subsystem forms a constituent part of the PTTCWS system and provides mobile communication network using a wireless router (WRAP100 access point) to establish communication between mobile phones.

   The purpose of this subsystem is to provide mobile communication and access to the local area network inside mine workings from tablets and smart phones connected via IEEE802.3 Wi Fi based on the implementation of the IP communication system.

      WRAP100 wireless routers are used to set up the WiFi radio communication network based on the data transmission network (MMDTS). These routers are connected with the surface communication server through the NAP100 underground node using optical fiber communication lines. This server can be connected to the existing automatic telephone station at the office to create shared address space for numbers. When the surface communication server is connected to the city automatic exchange, phone calls can be made to other localities directly from mine workings.
