Wifi vs bluetooth transfer speeds Bluetooth#

While we need to ascertain several influencing factors to determine if Wi-Fi is faster than USB, Bluetooth is with no doubt in last place when we speak about transfer speed. Essentially, Wi-Fi Direct falls under the same values presented at the Wi-Fi table (yet again keeping in mind that signal strength and range are the key factors for a good performance). Here the communication is performed at typical Wi-Fi speeds for everything from file transfer to Internet connectivity. Wi-Fi Direct, initially called Wi-Fi P2P, is a Wi-Fi standard that enables devices to connect easily with each other without requiring a wireless access point.

│ Protocol │ Data rate per stream (Mbit/s) │ Approximate range (m) │ USB 3.0: 5 Gbit/s (625 MB/s) which is more than 10 times as fast as USB 2 Wi-Fi USB 2.0: 480 Mbit/s (effective throughput up to 35 MB/s) USB 1.0: 1.5 Mbit/s (Low-Bandwidth) and 12 Mbit/s (Full-Bandwidth) There's also the physical limitation of the USB cable length that for some scenarios becomes a limitation. USB performance can be extremely low or very high, depending on the available USB version, which in turn, combined with the SDcard reading/writing speed on each device allows us to accurately measure and ascertain the transfer speed. There are many variables that affect the performance of each method you've mentioned.Īdditionally there's also the necessary configuration and requirements that each device must have in order to have solutions like this working.Īs requested, lets summarize and compare possible performances between USB Wi-Fi and Bluetooth: USB:
