Bluetooth<\/span><\/h3>\n

Bluetooth<\/a> (BT) is a medium, a technology that replaced the swarm of tangled wires and made wireless data transfer possible for short range. It is a medium that requires less power and has a lower hardware cost. This technology is supported and used on many devices like mobile phones, smartphones, speakers, headphones, medical devices, and advanced electronic systems. This medium made the lives of people easier and faster. Nowadays, IOT (short for Internet of Things) is gaining momentum and BT<\/a> is one of the core parts of IOT.<\/p>\n

In 1989 Ericsson, which is a Swedish multinational<\/a> networking and telecommunications company, started the development of \u201cshort link\u201d (later named as Bluetooth). By 1997, Ericsson developed a workable solution for developing wireless headsets. Also, in 1997 IBM and Ericsson collaborated to integrate Ericsson\u2019s mobile phones into IBM\u2019s \u201cThinkPad\u201d notebook but the integration failed because they were unable to reach power requirements. But they integrated Ericsson\u2019s \u201cShort-Link\u201d technology on both devices.<\/p>\n

As both products were quite unpopular at that time, they made \u201cShort-Link\u201d an open industry standard. After seeing the potential of \u201cBluetooth<\/a>\u201d, Intel, Nokia, and Toshiba joined with IBM and Ericsson and formed a Special Interest Group (SIG) in May 1998, they launched Bluetooth SIG to standardize this technology and create new advancements.<\/p>\n

The first BT<\/a> device was launched in 1999 which was a hands-free mobile headset used with mobile phones. Then, in 2001 Ericsson launched the first BT mobile phone T39 and after that, IBM launched its first BT notebook \u201cThinkPad A30\u201d in October 2001.<\/p>\n

This technology is a widely used medium in electronic devices because of its advantages like lower power consumption, lower manufacturing costs, reliability, and security. This wireless communication medium uses a frequency band between 2.400 GHz to 2.4835 GHz which is a globally unlicensed short-range radio frequency band. The maximum data transfer speed is 3 Mbps.<\/p>\n

Also, it uses Gaussian Frequency Shift Keying modulation which uses a frequency hopping technique to prevent interference in the 2.4 GHz band and leads to smoother data transition. However this technology has some limitations in comparison to Wi-Fi as BT has a limited range of 10 meters, so it restricts the data transfer for short distances, also the data transfer speed is slower than Wi-Fi and it is more prone to interference from other BT devices as 2.4GHz is a busy band.<\/p>\n

The SIG has launched different versions of BT wireless medium over the years like Version 1.0 (1999), 2.0 + EDR (2004), 3.0 + HS (2009), 4.0 (2010) and 5.0(2016).<\/p>\n
