Protocols are the most important element regarding how well your connected products perform, deciding how fast the world will adopt smart technology into their homes.
The key issue is the sector is highly fragmented, with different devices using a myriad of different protocols. Each protocol can only "talk" to other devices on their same protocol. This means that when you are deciding which device to install in your home, you won't necessarily be able to choose the one which is best for you.
One workaround is to have a smart home automation hub which can speak with all the different protocols. However, this can create latency issues within the network. An example of direct compatibility: your friend rings your doorbell camera while you are not at home, and you would like to let them in using your smart door lock. If they speak the same protocol (and have an adequate application), this would be a seamless, fast operation. However, if they do not speak the same language, you would need to change applications or enter into a different smart home hub automation hub application to finish the process. It may seem trivial—but these small inconveniences can make all the difference.
Which network protocol will win?
Our team at smarthomeSAGE predicts that Bluetooth Low Energy (BLE) will most likely win the network protocol battle for the following reasons:
The biggest issue which might interfere with Bluetooth Low Energy becoming the protocol of choice is the bandwidth interference. BLE uses the same bandwidth (2.4 GHz) as your WiFi and regular Bluetooth. In a house filling up with devices and sharing with your data-intensive laptops this could impact the long-term performance.
