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.
