The WNM Wireless Network Module from Moore Industries has been redesigned with a new, sleeker housing and now incorporates both Serial and Ethernet communications in one model. The product provides a low-cost wireless communications link between field sites that are in rugged or impassable terrain, with a single unit transmitting for up to 30 miles and the ability to act as a repeater for a virtually unlimited transmission range.
The bi-directional module employs Spread Spectrum Frequency Hopping technology to avoid interference problems caused by crowded radio spectrums. This technology allows multiple radio networks to use the same band while in close proximity. Operating at standard operating frequencies of 902-928MHz or 2.4-2.4835GHz, the WNM does not require a regulatory license and can typically be installed without performing costly RF site surveys.
The module utilises 128-bit AES (Advanced Encryption Standard) encryption, 32-bit CRC (Cyclic Redundancy Check) error detection and ARQ (Automatic Resend Query) for robust and secure communications. The industrial DIN-rail mount metal enclosure also ensures that the WNM can be used in rugged environments, including ambient temperatures from -40°C to 75°C and relative humidity of 5 to 95 per cent.
