An overview of WirelessHART’s OSI layers
In this first article on the reliable network communication protocol WirelessHART, we will focus our technical discussion on the OSI layers which are implemented in the protocol and their function within the protocol. Future articles will examine each of these … Continue reading
How does WirelessHART beat the 2.4GHz Traffic?
To many of us, 2.4GHz sounds like the traffic of Interstate 10 – or whatever freeway is close to you. It is overcrowded. WiFi, cordless phones, microwave ovens, and many other wireless technologies are taking advantage of this license-free frequency … Continue reading
Advantage of TDMA in WirelessHART over CSMA
In this fourth article in our technical discussion on the WirelessHART protocol, we look at the advantage of time division multiple access (TDMA) found in WirelessHART over carrier sense multiple access (CSMA). Both methods of allowing multiple nodes to communicate … Continue reading
