Despite its name, the Internet of Things (IoT) is not constricted to purely internet-based connectivity. In fact, Bluetooth Low Energy (BLE) solutions are increasing the functionality of IoT devices more successfully than via the internet, creating a more reliable framework for further connectivity. BLE technology will enhance and optimize the overarching operability of smart home devices by creating faster communication speeds and extending signal range.

Even though using the internet to connect devices works very well, it can have inconsistencies in its connection and shorten the battery life of various devices. These issues can be resolved through the use of BLE technology. Using BLE in IoT technology will allow devices to operate for extended periods of time on small power sources. In a readwrite article, it was stated that the new updates to Bluetooth technology made it possible for a coin-cell battery to last for several months, or even several years. Implementing Bluetooth technology within different IoT devices will help make managing a smart home a very energy efficient process.

The improved functionality of the IoT with the use of BLE goes far beyond simply saving power. BLE has the ability to extend the range of connection between devices by nearly four times that of a Wi-Fi network. This makes it a more reliable method for connecting numerous smart devices throughout a home environment. Not only is there a further range, but the communication speeds are revamped and much more capable to fulfill the demands of the always on and always communicating IoT devices.

Smart devices will be able to take full advantage of increased communication speeds and range due to the fact that BLE utilizes mesh networking. This is a network topology that allows for each device to be fully connected to each other within a network, allowing each node to assist in data distribution. The consumer benefit of mesh networking is explained by NXP; “Applications for Bluetooth mesh networks include those found in most every consumer’s home: door locks, lights, HVAC systems, and white goods (washers, dryers, refrigerators, and so on).” A mesh network is reliable for maintaining a smart home environment because individual devices can still communicate if one device runs out of power or is disconnected.

An increasing amount of manufacturers are beginning to integrate Bluetooth technology within their IoT technology. BLE will improve the overall functionality of the IoT and aid in establishing much more sturdy networks that will sustain the operation of numerous devices. This will help consumers create more efficient and powerful smart home environments.
