Let's know about Bluetooth Bluetooth is the most common wireless communication technology available for mobile phones. It has been undergone many changes during these years. It is used for exchanging data between devices over a short distance. It uses a short-wavelength Ultra High Frequency (UHF) bands. It is managed by the Bluetooth Special Interest Group (SIG). The IEEE standardized Bluetooth as IEEE 802.15.1. But it no longer maintains the standard. Versions Bluetooth 1.x: The basic Bluetooth rate with no additional/optional profiles or codecs. This version of Bluetooth is obsolete and was rarely implemented on mobile devices due to their limited speed of 1mbs and difficulty pairing. Bluetooth 2.x: The most popular variant of Bluetooth, especially in the earlier days when phones were not as advanced. It supports enhanced data rates (EDR) up to 3 Mbps and the V2.1 variant significantly simplified the pairing procedure making it more practical
Wi-Fi Let’s know about Wi-Fi In the world of wireless, the term Wi-Fi is synonymous with wireless access in general, although it specifies a trademark owned by the Wi-Fi Alliance, a group dedicated to certifying that Wi-Fi products meet IEEE 802.11 wireless standards. Wi-Fi networks have no physical wired connection between the sender and receiver, by using radio frequency (RF) technology -- a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that can propagate through space. Different Wi-Fi standards There are different Wi-Fi standards, each having its own significance. 802.11 • It’s the first Wi-Fi standard. • It operates in 2.4GHz frequency. • It provides a data rate of up to 2Mbps. 802.11b • It’s most likely the first router in your home was 802.11b. • It operates in 2.4GHz frequency. • It provides a
