Near field communication (NFC) is fundamentally different than the other wireless technologies discussed in this article. That speed comes at a price though and that price is mainly higher power consumption. In fact, WiFi Direct is over a hundred times faster than Bluetooth. The advantage of WiFi Direct over Bluetooth is mainly faster transfer speeds. It uses the same frequency and offers similar bandwidth and speed.īut, it doesn’t require an access point, allowing two devices to have a direct connection similar to Bluetooth. WiFi Direct uses the same basic technology as traditional WiFi. Like Bluetooth, but unlike traditional WiFi, WiFi Direct is a peer-to-peer wireless technology.Īs you probably already know, traditional WiFi sets up an access point that allows many devices to connect to it.īut what if you want to transfer data directly from one device to another without the overhead of an access point? That is where WiFi Direct comes into play. This is true even though nearly all phones and tablets support it.

WiFi DirectĮveryone knows about WiFi, but few people have heard of WiFi Direct. However, Bluetooth 5 which was introduced in 2016, has now essentially merged Bluetooth Classic (4.0) with Bluetooth Low-Energy, allowing both audio streaming and mesh networking all under the Low-Energy specification. It consumes much less power than WiFi, and a lot less than cellular technologies, but still significantly more than technologies such as Bluetooth Low-Energy or Zigbee. Bluetooth dominates peer-to-peer streaming audio applications such as this Bluetooth headset.īecause of the relatively short operating range, Bluetooth is fairly low power.
