It is preferred to use the newest possible security protocol, WPA3. WiFi on the other side was concerned with safety before, so it developed security protocols respectively WEP, WPA, WPA2, and WPA3. If you want to read more about setting proper BLE security, I recommend reading this article. In most cases still the best possible security standards aren’t implemented, but with proper setup, a connection could be secure. Securityīluetooth used to have serious security flaws in the past but most of them were solved with newer standards. Therefore WiFi is well-suited for transferring heavy data such as videos, photos etc.
#Iphone hotspot wifi vs bluetooth battery Bluetooth
Bluetooth Classic is 2-3 times faster.Įven slower WiFi standards as HaLow can send data up to 347 Mbps and faster standards can transmit data over 1.3 Gbps. BLE may only provide bandwidth around 1 Mbps. Because of that it's most suitable for transferring lightweight data such as numerical values from sensors. SpeedīLE was designed to send small chunks of data. It was made specifically for IoT, providing lower energy consumption and higher transmission range than previous standards, but hasn’t been used extensively yet.
In 2017 new protocol called WiFi HaLow was published. WiFi operates on 2.4Ghz or 5Ghz frequencies and typically works over longer distances than bluetooth. WiFi is technology for radio wireless local area networking of devices based on the IEEE 802.11 standards. This new variant is widely used in IoT as its low power consumption perfectly fits in this use-case. Bluetooth 4 specification introduced Bluetooth Low Energy (BLE). It was thought of as replacement of RSS cables. Therefore I will try to make your choice easier by comparing those two wireless connection technologies.īluetooth is a wireless technology standard for exchanging data over short distances.
“Should I choose Bluetooth or WiFi for my IoT project?” is a common question nowadays. Although both of them originated a long time before IoT was a thing and were thought for other use-cases, now they are conquering its market.
But out of them all, the two most popular ones are Bluetooth and WiFi. We have many connection standards available today like NFC, IR, and more. With the need for the new IoT solutions come questions about wireless communication. Even more than that, it’s still growing by the day and it’s not slowing down anytime soon. IoT grew tremendously in previous years and as of now, it’s one of the top trend in the technology world.
