Frequency-hopping serial radios
By Plant Engineering Staff -- Plant Engineering, 8/15/2008 12:00:00 AM MT
RLX-IFHS industrial frequency-hopping serial radios are license-free and available in both 900-MHz and 2.4-GHz bands. They use a proprietary signal that hops from channel to channel, which provides the wireless network with an extra layer of security and allows it to avoid interference. The 900 MHz radios are suitable for long-range SCADA applications or applications with challenging paths, including penetration of foliage and walls. The 2.4 GHz radios can be used when 900 MHz is not permitted. The radios can communicate with Modbus, DF1, ASCII or most other serial devices.
