WirelessHART is the first open wireless protocol certified for industrial applications, providing backward compatibility with HART technology. It features a mesh network topology with secure data link layers and utilizes a multi-vendor support system for process monitoring and control. The protocol offers cost savings, easy installation, and improved access to information in hard-to-reach areas.

6. WirelessHART Main Features
Mesh Topology
- Routers
- Spatial diversity

7. WirelessHART Main Features
Channel hopping
- Frequency diversity
- Only nodes in the network
know next channel

8. WirelessHART Main Features
Acknowledgment
- Synchronous
operation
Non broadcast messages have ACK which also is use as a sync
mechanism among the nodes in the network.
