Bluetooth is used in almost all major consumer products including phones, tablets, laptops, headphones, speakers, TVs, and fitness wearables just to name a few. However, despite its widespread use, there are still some myths and misconceptions that still persist about Bluetooth technology. Let’s explore some of these myths and the true facts about Bluetooth.
Myth 1: Bluetooth technology is only used for consumer products
There’s a widespread misconception that Bluetooth is a consumer-only technology. However, the reality is, Bluetooth technology is being used for many different enterprise IoT applications such as Industrial IoT, Digital Health, Smart City, as well as Personnel & Asset Tracking. Developers around the world have seen the tremendous value that Bluetooth technology can offer in order to help scale their large IoT deployments. The sheer number of Bluetooth-enabled devices on the market and the ease of programming Bluetooth compatible applications makes it an important technology for today’s enterprises to implements their IoT solutions.
Myth 2: Bluetooth only works within a short distance
Truth is, Bluetooth technology is designed to support a wide range of distances between devices. The reliable range between Bluetooth devices is anywhere from one meter up to 1 kilometer. The wide range of distances gives developers much more flexibility to develop solutions that meet their unique use case. It’s important to note that several factors can influence the range of a reliable Bluetooth connection such as radio spectrum, transmit power as well as antenna gain so it’s imperative that these factors are taken into consideration when determining Bluetooth’s range.
Myth 3: Bluetooth interferes with Wi-Fi
Like Wi-Fi and other wireless technologies, Bluetooth uses the 2.4 GHz radio frequency to send and receive data. When two devices are connected, Bluetooth uses adaptive frequency hopping (AFH) to help minimize the effects of interference with other devices. Essentially, the signal rapidly “hops” from one frequency to another to ensure that it won’t get disrupted by other devices trying to use that band. So, while other wireless connections can seek to use the same frequency that Bluetooth is using, AFH keeps the connection stable without drops in speed and stability.
In sum, while these myths do exist, it’s important to understand the true value that Bluetooth technology can offer not only for consumer applications, but for enterprises looking for a low cost wireless technology solution to scale their IoT projects.
