| Wireless I/O
Wireless I/O, also known as radio telemetry, connect directly to sensor and control signals, and transmit the signal values by radio. The signals are either re-created as similar signals, or output as a data connection — Ethernet, Profibus, Modbus etc. Wireless I/O networks can be as simple as two units transferring a small number of signals from one point to another, or they can be complex data-acquisition networks with multiple “master” interfaces to external systems. |

| Wireless Gateways
Wireless Gateways provide wireless connectivity between data buses - connectivity between devices using the same data bus, or between different data buses (Ethernet to Profibus to DeviceNet to Modbus etc). Wireless gateways are similar in operation to wireless modems, however gateways only provide a register interface to the data bus, transferring I/O registers only. |

| Wireless Modems
Wireless Modems transmit serial or Ethernet data, providing a wireless extension of the data link. Example applications are PLC to PLC connections (point-to-point), connecting SCADA to a group of PLCs (point-to-multipoint), or forming a wireless PLC LAN (multidrop). Wireless modems transmit the data with minimal transformation. |

| GPRS Alarm Modems
Wireless GPRS Alarm Modems use GSM mobile technology to provide alarm and status information directly to a mobile device, SMS, email, or via fax. The GPRS Alarm Modem can be located anywhere GSM reception is available. Site, remote location, or plant monitoring can be conducted remotely without the need for onsite employees. |
