We believe the protocols are just a path to communication and essentially do the same thing, just move data. Bluetooth is good for media, Zigbee and Z-Wave are centered on sensors and cant do media very well.
So I think we should stop fighting on protocols and concentrate on the first word in IoT – Internet. IP will be the unifying protocol. What is happening right now is every major manufacturer is trying to build a brain, a hub, a gateway. These brains usually speak a few protocols like Zigbee, Z-Wave and BLE. But new versions are adding more and more protocols. Is this good? Is one protocol going to win? Or are we all going to turn buildings into multi protocol microwave? Below are few examples of these brains.
Here you can even find a deeper list of just the Z-Wave hubs.
More importantly, what we are starting to see is that chip sets are begin to reflect this multi protocol acceptance. Usually the first set of protocols that are integrated are, Zigbee, Z-Wave and BLE. Below you can find few examples of how computing is being merged with these communication protocols, through such chipsets.
What we are more interested to see how the Network Topologies get decided. Refer to the right. Network Topology is a conversation on its own, whcich my colleagues and I discuss in depth. Maybe another blog post.
In the mean time. We, at Locbit, have to support this dispersed protocols.
