Radio Extends Reach of Surecross Wireless Systems

The new Multi-Hop data radio from Banner Engineering is suitable for applications such as irrigation, automated parking, coal, power generation, oil and gas, grain handling and metalworking. The device - which is also suitable for water and wastewater treatment, facilities monitoring, factory automation, chemical processing, cement, mining and material handling - extends the reach of the company's Surecross wireless systems by repeating transmissions in 3km 'hops' to a multi-hop total of 20km or more.

Multiple units can be placed to allow signals to pass over hills and other obstacles that would block a single wireless hop. The Multi-Hop data radio can be used to connect a variety of field devices directly, including programmable logic controllers, human-machine interfaces, transmitters and level, pressure and temperature sensors. It enables the extension of the widely used Modbus communication protocol to many applications where wiring is impractical because of distance or accessibility.

The device can also be connected with digital, analogue or temperature signals using other Banner wireless products. The large wireless networks enabled by the new radio provide previously unavailable information to users in a range of industries. In irrigation, soil moisture can be measured, zone valves operated and flow rate measured. In automated parking applications, thousands of parking spots around a city can be monitored.

More traditional applications include tank-level, pressure, flow and temperature monitoring in a variety of markets. Using the Multi-Hop data radio, clusters can be combined and connected to create systems with 2,400 wireless points, covering more than 100km2. For even larger systems, multiple wireless networks can co-exist in the same physical area without interference. The radios are configured for rapid, easy connection to all remote and central control elements in a network. They can be powered by 10-30VDC, battery or solar power supply, allowing wireless repeaters to be placed where no power is available.
