We will introduce Bluetooth and WiFi connection technologies in more detail and compare them based on the most important features in commercial and industrial IoT applications.

Bluetooth technology

Bluetooth technology Definition

Bluetooth technology is a low-power wireless solution operating on the 2.4 GHz ISM-Frequenzband. Im Laufe der Jahre, Die Bluetooth-Technologie hat sich immer weiter ausgeweitet, and now it has great flexibility in terms of distance, Bandbreite, and communication topology, which can meet the needs of different IoT applications.

Bluetooth technology Technical Details

Derzeit gibt es zwei verschiedene Bluetooth-Funkoptionen: Bluetooth Classic and Bluetooth Low Energy (Bluetooth le). Klassisches Bluetooth (oder BR/EDR), das Original-Bluetooth-Radio, wird immer noch häufig in Streaming-Anwendungen verwendet, especially audio streaming.Bluetooth Low Energy-Modul is mainly used for low-bandwidth applications where data is frequently transmitted between devices. Bluetooth Low Energy ist für seinen extrem geringen Stromverbrauch und seine Beliebtheit in Smartphones bekannt, Tablets und PCs.

Bluetooth Low Energy ist in Punkt-zu-Punkt unterteilt, star, mesh and broadcast topologies. In der Mesh-Topologie, the nodes are directly connected without communicating with other nodes through the hub. Knoten können Daten und Informationen an andere Knoten außerhalb des Kommunikationsbereichs des ursprünglichen Quellknotens senden, expanding the network coverage in a large area.

Bluetooth technology Anwendung

Bluetooth Low Energy is most commonly used in medical and fitness equipment, smart lighting systems, real-time positioning systems, and indoor navigation applications.

W-lan Technologie

W-lan Technologie Definition

Wi-Fi is the brand name of all IEEE 802.11 Standard-Wireless-Local-Area-Netzwerke (WLAN). Das Arbeitsfrequenzband von Wi-Fi ist normalerweise 2.4 GHz und 5 GHz-ISM, aber neuere WLAN-Versionen nutzen auch andere Frequenzbänder.

W-lan Technologie Technical Details

Es gibt viele Versionen von Wi-Fi. Die Wi-Fi Alliance hat kürzlich ein neues Versionsnummerierungssystem eingeführt: W-lan 1 (802.11B), W-lan 2 (802.11A), W-lan 3 (802.11G), W-lan 4 (802.11N, W-lan 5 (802.11AC) und WLAN 6 (802.11Axt). Die neueste Version kann die Anforderungen verschiedener Anwendungen erfüllen, including longer distance, höherer Durchsatz und größere Abdeckung.

The most popular topology for Wi-Fi is the star topology. Aber in der Sterntopologie, Knoten können nur über den Hub miteinander kommunizieren.

W-lan Technologie Anwendung

Wi-Fi is mainly used for large file transmission and data transmission applications with high bandwidth, such as video streaming.

In IoT applications, Wi-Fi is most commonly used for devices that need to directly connect to the Internet. But it usually cannot meet the low power consumption requirements, and it is rarely used in applications and devices that need to run on micro batteries for a long time.
