WIB™-net Communications

 

Cooper Crouse Hinds innovative WIB™-net communications protocol is specifically designed for highly reliable and secure operation on open license-free radio bands.

WIB™-net provides the following features:

Exception Reporting

Transmissions for maximum wireless efficiency. Wireless messages are only transmitted whenever a signal value changes, yielding effective real-time performance. Integrity check messages ensure reliable operations of the wireless network as well as signal link accuracy. Exception-reporting reduces I/O traffic to messages of only real significance (whenever a change occurs); and when there is an I/O change,  a message is sent immediately without having to wait for poll permission.

Error-Checking with Automatic Retransmission

For high reliability operation.  Every radio message has a probablility of corruption, so automatic error detection,  acknowledgement and re-transmission is critical to reliable operation. WIB™-net will try five times to send a message with random time between messages. After the fifth attemps, a communication-failure status is logged and alarmed.

Listen-Before-Transmit

Wireless operation to maximise the chance of successful message transmission.

Peer-to-Peer Networking

Provides maximum network flexibility. Each Cooper Crouse Hinds wireless unit can transmit directly to any other wireless unit, and can transmit to mulitple wireless units. There are no master units and no slaves. Input signals can be transmitted to multiple destinations.

High Security Encryption

WIB™-net uses a highly secure data encryption technique to protect against mis-use of wireless data. The level of security of Cooper Crouse Hinds wireless I/O networks is at an equivalent or higher level than wired networks.

Wireless Mesh Structure

WIB™-net enables every Cooper Crouse Hinds wireless unit to act as a repeater to optimize wireless message propogation. Messages can hop through multiple units to reach a destination. Provides each Cooper Crouse Hinds Wireless I/O unit has a reliable wireless link to at least one other unit, a wireless mesh forms to enable reliable linkages to the whole network.
