In normal use, ten meters is a good guide to what can be achieved between two Bluetooth devices indoors. When developing a Bluetooth device, you can give your device a better range by selecting the Bluetooth chip with the best receiver sensitivity and output power, and making sure that you use a good antenna.


Range of Bluetooth is dependant on its class and primarily there are three classes of Bluetooth: Class 1 transmitting at 100 mW with a range of 100 meters or 328 feet.; Class 2 transmiting at 2.5 mW with a range of 10 meters or 33 feet (most Bluetooth headsets and headphones are common Class 2 devices).; Class 3 transmitting at 1 mW with a range of fewer than 10 meters.


Range is essentially going to be good enough for a normal sized room to be covered. It can be longer or shorter depending on environmental circumstances, but remember that bluetooth was created to implement short range connections. A bluetooth device can be part of a piconet of eight devices, one master and up to seven slaves.


The Bluetooth specification stipulates a minimum range of 33 feet, but the maximum range is determined only by the output power of the device. Frequency Band Bluetooth technology operates in the industrial, scientific and medical frequency band of the radio spectrum between 2.4 and 2.485 gigahertz.


Class 2 : Max range is about 50m (150ft) Class 1 : Max range is about 100m (300ft) These ranges can be affected by environmental conditions i.e. furniture, walls, people so ranges can easily be reduced. Bluetooth is not a line of sight connection so it can be used through walls and floors.


More recently, we've had Bluetooth Smart or Bluetooth Low Energy (technically referred to as Bluetooth Version 4.0+). As these names suggest, this version is better at connecting a wider range of simpler devices, uses much less power, and is much easier to integrate into mobile (iOS and Android) applications.


High-powered Bluetooth devices will enable ranges up to 100m (300ft). Considering the design philosophy behind Bluetooth, even the 10m range is adequate for the purposes Bluetooth is intended for. Later versions of the Bluetooth spec may allow longer ranges. <top> Q: What kind of encryption will be used for Bluetooth security?


Bluetooth Range. Among different bluetooth specifications, there are 2 most popular classes (types) of devices: Class 1: range up to 100 meters (in most cases 20-30 meters) Class 2: range up to 30 meters (in most cases 5-10 meters) Additional facts: the range depends not only on the transmitter, but also on the mobile phone which is receiving ...


While Bluetooth technology is a wireless technology, there are significant differences between Bluetooth, Wi-Fi, and GPS technology. Note: Depending on your environment, the Bluetooth range might vary.


How Far Does Bluetooth Reach? Signals transmitted using Bluetooth, a technology for connecting devices wirelessly across short distances, reach about 32 feet. Bluetooth transmission is relatively weak so that it does not interfere with TVs and other electronics.
