│ Network Type │ Point-to-point │ WPAN │ WPAN | │ Aspect │ NFC │ Bluetooth │ Bluetooth Low Energy │ NFC is even slower than Bluetooth (both short-range communication technologies) and is limited to about 20cm of range getting up to 424 kbit/s. Android Beamīeing a fairly recent technology, Android Beam allows users to transfer data between devices with Near Field Communication (NFC) capabilities. ├─────────────┤ theoretical data transfer speeds of up to 24 Mbit/s │ │ Version │ Data rate │ Maximum application throughput │ 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. More about Wi-Fi protocols from Wikipedia. │ | Bandwidth of 20 MHz | indoor | outdoor │ │ 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:
