Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart [1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) [2] aimed at novel applications in the healthcare, fitness, beacons, [3] security, and home entertainment industries. [4]
Maximum power output from a Bluetooth radio is 100 mW for Class 1, 2.5 mW for Class 2, and 1 mW for Class 3 devices. Even the maximum power output of Class 1 is a lower level than the lowest-powered mobile phones. [164] UMTS and W-CDMA output 250 mW, GSM1800/1900 outputs 1000 mW, and GSM850/900 outputs 2000 mW.
A power level of 0 dBm corresponds to a power of 1 milliwatt. A 10 dB increase in level is equivalent to a ten-fold increase in power. ... Bluetooth Class 2 radio, 10 ...
The power transmission frequency is 6.78 MHz, and up to eight devices could be powered from a single PTU depending on transmitter and receiver geometry and power levels. A Bluetooth Low Energy link was defined in the A4WP system intended for control of power levels, identification of valid loads and protection of non-compliant devices. [3] [4]
Some of these technologies include standards such as ANT UWB, Bluetooth, Zigbee, and Wireless USB. Wireless Sensor Networks (WSN / WSAN) are, generically, networks of low-power, low-cost devices that interconnect wirelessly to collect, exchange, and sometimes act-on data collected from their physical environments - "sensor networks". Nodes ...
For example, Bluetooth provides a much shorter propagation range between 1 and 100 metres (1 and 100 yards) [111] and so in general has a lower power consumption. Other low-power technologies such as Zigbee have fairly long range, but much lower data rate. The high power consumption of Wi-Fi makes battery life in some mobile devices a concern.
RIC – There are three receiver-in-canal models that come in seven colors, four technology levels and can be either rechargeable or disposable battery-operated. All RIC options are Bluetooth-enabled.
