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.
