Bluetooth and Wi-Fi (Wi-Fi is the brand name for products using IEEE 802.11 standards) have some similar applications: setting up networks, printing, or transferring files. Wi-Fi is intended as a replacement for high-speed cabling for general local area network access in work areas or home. This category of applications is sometimes called wireless local area networks (WLAN). Bluetooth was intended for portable equipment and its applications. The category of applications is outlined as the wireless personal area network (WPAN). Bluetooth is a replacement for cabling in various personally carried applications in any setting and also works for fixed location applications such as smart energy functionality in the home (thermostats, etc.).

That means the new version of Bluetooth was designed to use less power on each device than version 4.0. For instance, all audio devices communicate over BLE, and you can switch on your Bluetooth for a more extended period without worrying about the battery running out.Wi-Fi and Bluetooth are to some extent complementary in their applications and usage. Wi-Fi is usually access point-centered, with an asymmetrical client-server connection with all traffic routed through the access point, while Bluetooth is usually symmetrical, between two Bluetooth devices. Bluetooth serves well in simple applications where two devices need to connect with a minimal configuration like a button press, as in headsets and speakers. Short-range transmission of health sensor data from medical devices to mobile phone, set-top box or dedicated telehealth devices. [46] [47] a b Guy Kewney (16 November 2004). "High speed Bluetooth comes a step closer: enhanced data rate approved". Newswireless.net. Archived from the original on 15 January 2018 . Retrieved 4 February 2008. Bluetooth uses the radio frequency spectrum in the 2.402 GHz to 2.480 GHz range, [157] which is non-ionizing radiation, of similar bandwidth to that used by wireless and mobile phones. No specific harm has been demonstrated, even though wireless transmission has been included by IARC in the possible carcinogen list. 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. [158] UMTS and W-CDMA output 250 mW, GSM1800/1900 outputs 1000 mW, and GSM850/900 outputs 2000 mW.

Nonetheless, these are commendable improvements, and they also apply to BLE, so your IoT devices can benefit from better speed and range while still being power-efficient.

Some features were already available in a Core Specification Addendum (CSA) before the release of v4.1.Wireless control of audio and communication functions between a mobile phone and a Bluetooth compatible car stereo system (and sometimes between the SIM card and the car phone [37] [38]).

Enhanced Retransmission Mode (ERTM) This mode is an improved version of the original retransmission mode. This mode provides a reliable L2CAP channel. Streaming Mode (SM) This is a very simple mode, with no retransmission or flow control. This mode provides an unreliable L2CAP channel. Bluetooth was only intended as a placeholder until marketing could come up with something really cool.

Dual Band WiFi & BT4.0】The Mini Computer W++11 is equipped with 2.4/5.8G dual-band WiFi with a maximum speed of 1000Mbps, which can easily meet the needs of big data transmission and process multiple online tasks at the same time without delay. In addition, it also has BT4.0, which means you can easily connect to your wireless device, saving desktop space and making the desktop look bigger and more beautiful.

The Bluetooth Innovation World Cup, a marketing initiative of the Bluetooth Special Interest Group (SIG), was an international competition that encouraged the development of innovations for applications leveraging Bluetooth technology in sports, fitness and health care products. The competition aimed to stimulate new markets. [159]
