In WiFi modulation technique is OFDM(Orthogonal Frequency Division Multiplexing) and QAM(Quadrature Amplitude Modulation). In Bluetooth modulation technique is GFSK(Gaussian frequency shift keying). WiFi demands a wireless router to set up the connectivity and adapter on the device. same unlicensed 2.4 GHz Industrial, Scientific, and Medical (ISM) frequency band as Wi-Fi. Whereas in wifi this range is hundred meters.īluetooth frequency range 2.400 GHz to 2.483 GHzīluetooth demands a bluetooth setting or adapter on all device to set up connectivity. Comparison of Bluetooth LE stack and OSI reference model. The radio signal range of bluetooth is ten meters. Whereas wifi supports large amount of users. While it provides better security than bluetooth.īluetooth is less flexible means in this limited users are supported. The security of bluetooth is less in comparison of wifi. Whereas it requires wireless adapteron all devices and wireless router for connectivity. It requires bluetooth adapter on all devices for connectivity. Let’s see the difference between Bluetooth and Wi-Fi: S.NO Wifi provides high information measure because the speed of web is a vital issue. The most distinction between Bluetooth and Wifi is that, Bluetooth is actually accustomed connect short-range devices for sharing information whereas Wifi is used for providing high-speed web access or internet. Network Devices (Hub, Repeater, Bridge, Switch, Router, Gateways and Brouter)īoth Bluetooth and Wi-Fi are used for providing wireless communication through radio signals.Challenge Response Authentication Mechanism (CRAM). AAA (Authentication, Authorization and Accounting) configuration (locally).The radio and baseband functions are mapped to the physical layer on. Computer Network | AAA (Authentication, Authorization and Accounting) The Bluetooth protocol architecture is shown along with the OSI model in Figure 12-3.Service Set Identifier (SSID) in Computer Network.How Address Resolution Protocol (ARP) works?.ARP, Reverse ARP(RARP), Inverse ARP (InARP), Proxy ARP and Gratuitous ARP.Figure 13 shows the familiar Open Systems Interconnect (OSI) standard reference model for communications protocol stacks. Mobile Internet Protocol (or Mobile IP) There are also profiles which give details of how applications should use the Bluetooth protocol stack, and a brand book which explains how the Bluetooth brand should be used.Difference between Bluetooth and Zigbee.
