Bluetooth VS WiFi-teknologi sammenligning
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 frekvensbånd. Gjennom årene, Bluetooth -teknologien har fortsatt å utvide, and now it has great flexibility in terms of distance, båndbredde, and communication topology, which can meet the needs of different IoT applications.
Bluetooth technology Technical Details
Det er for øyeblikket to forskjellige Bluetooth -radioalternativer: Bluetooth Classic and Bluetooth Low Energy (Bluetooth Le). Klassisk Bluetooth (eller BR/EDR), den originale Bluetooth -radioen, er fremdeles mye brukt i streaming -applikasjoner, especially audio streaming.Bluetooth Low Energy Module is mainly used for low-bandwidth applications where data is frequently transmitted between devices. Bluetooth lav energi er kjent for sitt ekstremt lave strømforbruk og popularitet i smarttelefoner, Nettbrett og personlige datamaskiner.
Bluetooth lav energi er delt inn i punkt-til-punkt, star, mesh and broadcast topologies. I nettetopologien, the nodes are directly connected without communicating with other nodes through the hub. Noder kan sende data og informasjon til andre noder utenfor kommunikasjonsområdet for den opprinnelige kildeknuten, expanding the network coverage in a large area.
Bluetooth technology Søknad
Bluetooth Low Energy is most commonly used in medical and fitness equipment, smart lighting systems, real-time positioning systems, and indoor navigation applications.
Wifi teknologi
Wifi teknologi Definition
Wi-Fi is the brand name of all IEEE 802.11 Standard trådløse lokale nettverk (Wlan). Arbeidsfrekvensbåndet til Wi-Fi er vanligvis 2.4 GHz og 5 GHz ISM, Men nyere versjoner av Wi-Fi bruker også andre frekvensbånd.
Wifi teknologi Technical Details
Det er mange versjoner av Wi-Fi. Wi-Fi-alliansen vedtok nylig et nytt versjonsnummereringssystem: Wi-Fi 1 (802.11b), Wi-Fi 2 (802.11en), Wi-Fi 3 (802.11g), Wi-Fi 4 (802.11n, Wi -fi 5 (802.11Ac) og Wi-Fi 6 (802.11øks). Den siste versjonen kan imøtekomme behovene til forskjellige applikasjoner, including longer distance, høyere gjennomstrømning og større dekning.
The most popular topology for Wi-Fi is the star topology. Men i stjernetopologien, Noder kan bare kommunisere med hverandre gjennom huben.
Wifi teknologi Søknad
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.
