Bluetooth was developed by Ericsson in 1994 uses short-wavelength UHF waves between 2402 and 2480 MHz. Widely known as the best wireless transmission technology for audio and the ubiquitous solution for hands-free calling in automobiles. Bluetooth is making waves in consumer and business IoT where device-to-device communication needs to be fast, easy, and wireless.
Bluetooth(BLE) for IoT
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. This creates 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, inconsistencies in its connection will shorten the battery life of various devices. BLE technology resolves these issues. Using BLE in IoT technology, devices will operate for extended periods of time on small power sources. 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 4 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. This is due to the fact that BLE utilizes mesh networking. It 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 the data distribution. A mesh network is reliable for maintaining a smart home environment. It’s 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.
Applications Of Bluetooth In IoT
Applications for Bluetooth mesh networks include those found in almost every consumer’s home. These include door locks, lights, HVAC systems, and white goods (washers, dryers, refrigerators), and so on. You use your smartphone in your car for audio streaming, GPS updates, or hands-free calling. But Bluetooth has much more to offer than a safer, more attentive commute though. Devices ranging from coffee machines to thermostats are being built with Bluetooth access. Meaning, all it takes to brew your coffee and warm your house are a few taps on your phone.,
Health and fitness is another area of broad Bluetooth adoption. Wearable tracking devices and pedometers like the popular Fitbit — easily sync to smartphones using Bluetooth. Consider chronic health conditions like sleep apnea. Here remote patient monitors are now equipped to track a person’s progress and the nuances of a medical condition. The information is archived, via Bluetooth.
In industry, Bluetooth is primarily used in machine-to-machine communications and connections before the information is sent to a gateway. It happens since Bluetooth makes it very easy for devices to communicate with each other. For example, in a factory or warehouse, employees can receive Bluetooth alerts from machinery on their tablets or smartphones. This information can be logged for record-keeping purposes, saving the company money or even employee’s lives.
