With the rapid development of the Internet of Things (IoT), Bluetooth Low Energy (BLE) technology has become increasingly important. As the latest version of BLE technology, BLE 4.0 has sparked intense interest in its range. So, how far can BLE 4.0 reach? Today, we’ll uncover the mysteries of BLE 4.0 range. Overview of BLE 4.0 Technology BLE 4.0 is the fourth generation of BLE technology, released by the Bluetooth Special Interest Group (SIG) in 2010. This technology marks a significant leap forward in BLE, featuring lower power consumption, faster data transmission speeds, and longer communication distances. How Far Can BLE 4.0 Reach? The range of BLE 4.0 refers to the maximum communication distance between devices. In ideal environments, BLE 4.0 can reach up to 100 meters (328 feet). However, actual environments are often affected by interference, obstacles, and other factors that can impact BLE 4.0 range. The main factors that affect BLE 4.0 range include: Environmental interference: Signals from Wi-Fi, Bluetooth, and mobile phones can interfere with BLE 4.0 signals. Obstacles: Walls, pillars, and furniture can block BLE 4.0 signals. Device transmission power: Higher transmission power can increase BLE 4.0 range. Receiver sensitivity: Higher receiver sensitivity can also increase BLE 4.0 range. BLE 4.0 Range Testing To better understand BLE 4.0 range, we conducted a series of tests. The test environment was an open, obstacle-free area, with BLE 4.0 devices transmitting at 4dBm and receiving at -90dBm. The test results were: In an open, obstacle-free area, BLE 4.0 range reached… Read more
