Many existing meters, data loggers, RTU's, PLC's, point-of-sale, and other remote devices only have physical interfaces designed to access the telephone network. They do not have serial or Ethernet ports. They currently use analog cellular or standard phone lines to connect in circuit- switched mode for data transfer.
Analog cellular phone service is being discontinued. The combination of the Host RJ-11 IP Gate- way, RJ-11 IP Gateway, and the AirLink Raven-E enables remote connectivity between host appli- cations and these remote devices over cellular packet data networks. The RJ-11 IP Gateway provides the bridge between a device requiring an RJ-11 interface and the Raven-E, with its Ether- net interface. The Host RJ-11 IP Gateway can provide Ethernet-based Internet connectivity to a Legacy Host system with only RJ-11 ports.
