Like everything in life, there are advantages and drawbacks. It also works well when making small data transfers between adjacent devices, including cell phones, modems, and speakers. This technology is best suited for short-range communication between devices, such as wearing a Bluetooth-enabled headset close to your cell phone. Transferring large files (e.g., videos) via Bluetooth is, therefore, slow and inconvenient. Unlike traditional remote control devices, Bluetooth doesn’t need a clear line of sight for device communication and doesn’t use infrared technology.Īlthough Bluetooth uses less power than WiFi, this limits the connection speed and data transfer rate. One of the main differences between WiFi and Bluetooth is that Bluetooth doesn’t need a router or bridging device to connect to the Internet.īluetooth technology was initially designed in the late 1990s to facilitate the transfer of information between nearby devices. Like WiFi, Bluetooth provides an Internet connection using radio signals and doesn’t require a wired connection. Over the years, WiFi technology has improved to enable greater bandwidth to be faster when transferring data.

WiFi range has, over the years, improved and is now 35 meters (115 feet).Ī WiFi connection works on either a 5 GHz or 2.4 GHz frequency to provide a wireless internet connection for any device connected to it. When WiFi was first invented, it was similar to Bluetooth’s range at 20 feet (6 meters). This facilitates the connection of multiple devices to the wireless connection. Breaking up the signal allows it to be sent using a low amount of power. When a WiFi connection is created, the router breaks the signal up into tiny fragments, which are then transmitted over a radio frequency. This is called a WLAN (or Wireless Local Area Network). Using a router for Internet connectivity, WiFi grants permission for devices to connect through a password. WiFiįirst brought on to the market in 1991, WiFi is now a popular method to connect smart home devices to the Internet. Bluetooth for home automation uses radio signals without a wired connection or bridging device and uses less power than WiFi. It transmits the signal over a 5 GHz or 2.4 GHz radio frequency. WiFi for home automation works by using a router to grant permission for devices to connect via a WLAN. Before we decide whether Bluetooth or WiFi is better for home automation, we need to understand how each one works: WiFi, Bluetooth, and mesh networks are considered the best options for connecting your smart home devices. When your home automation devices are connected and communicate, it is known as the Internet of Things (IoT).

How Do WiFi and Bluetooth Work for Home Automation?įor a home automation system to work, it needs to be connected to the Internet, which can be done in several ways.
