The rates advertised is the maximum raw throughput achievable at PHY level, in "ideal channel conditions". AMP is not used by many people today I guess.ģ] PHY Data rates and achievable data rates This approach was to solve Bluetooth's bandwidth problem.
#Bandwidth wifi vs bluetooth Bluetooth#
There is a technology called AMP as part of Bluetooth spec 4.0, where Bluetooth protocol stack sits on top of WLAN MAC. Higher data rates means more power, this also means your devices battery power will be drained faster.Ģ] Is it possible to have Bluetooth-5 with more bandwidth than 802.11-n?Ībsolutely possible, if Bluetooth protocol stack is placed on top of a higher bandwidth PHY, Bluetooth will achieve higher bandwidth. So WiFi's physical layer is designed to have higher data rates. WiFi is designed as a wireless rival of Ethernet. Basically Bluetooth's PHY layer uses low data rate's because low data rate require very little power. So data rates are restricted in the PHY to achieve this low power usage. Bluetooth is designed as a technology that uses very low amount of power. The factor which makes the difference is power usage. sacrificing speed in favor of low power consumption)?Įdit: to be clear, I understand that the listed data rates are theoretical maximums and do not reflect real world performance.īoth Bluetooth and WLAN operates on ISM band 2.4GHz.Īdditionally WiFi has a version that operates on 5 Ghz band too.ġ] Why WiFi has more bandwidth or speed than Bluetooth?īecause WiFi is designed to have more speed than Bluetooth. Is it possible we could get a "Bluetooth 5" with bandwidth on the order of 802.11a or 802.11n, or is there some deliberate design decision that results in low transfer rates (e.g. Is it simply because the standard set by the governing body intentionally sets a lower data transfer rate in order to allow hardware costs to stay low? Why does Bluetooth have so little throughput compared to the Wi-Fi standards? Here is a relevant selection from the link: While researching wireless communication protocols for a potential application, I came across this page on Wikipedia which lists throughput rates for both Bluetooth and 802.11 networks:
