New versions of Bluetooth were encryption and even now Bluetooth security is limited to key matching whereas Wi-Fi security standards have been raised with the inclusion of new versions.Bluetooth is fairly simple as there is just a simple key matching process for connecting two devices while Wi-Fi needs expertise in configuration and security passcode matching process so Wi-Fi connection process is much more complex than Bluetooth.In Bluetooth, up to 7 devices can be connected to each other while in Wi-Fi maximum connections depend on Wi-Fi router which can accommodate several connections at a time.In Wi-Fi, range depends on the version of Wi-Fi protocol and antennas in the wireless communication system. Bluetooth based wireless connections maximum range is 30m while for Wi-Fi, it can extend well up to 100m.The latest updates of Bluetooth promises data transfer rates up to 25 Mbps while the latest Wi-Fi updates can reach up to 250 Mbps of data transfer rates.Bluetooth works at the frequency range of 2.400 GHz and 2.483 GHz while Wi-Fi works at the range of 2.4 GHz and 5 GHz.These versions vary in terms of security protocols, radio frequency used for data exchange, maximum speed for data exchange, the bandwidth occupied etc. Bluetooth update several versions such as Bluetooth 2.0, 2.1, and Bluetooth 3.0 and latest Bluetooth 4.0 added technologies such as Enhanced Data Rate (EDR), alternate MAC/PHY, low energy protocols have been implemented in these updates whereas Wi-Fi updates is quite different such as IEEE 802.11 standard such as IEEE 802.11a, b, c etc.Bluetooth was initially defined under IEEE 802.15.1 standard but is now taken care by a special interest group SIG, on the other hand, Wi-Fi is defined under 802.11X where X is a, b, c etc series of protocols and is currently maintained under the same.

So now let us check it out the difference between Bluetooth and WiFi to know more understanding about Bluetooth and WiFi.
