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 Frekuensi Band. Selama bertahun -tahun, Teknologi Bluetooth terus berkembang, and now it has great flexibility in terms of distance, bandwidth, and communication topology, which can meet the needs of different IoT applications.

Bluetooth technology Technical Details

Saat ini ada dua opsi radio Bluetooth yang berbeda: Bluetooth Classic and Bluetooth Low Energy (Bluetooth LE). Bluetooth klasik (atau br/edr), Radio Bluetooth Asli, masih banyak digunakan dalam aplikasi streaming, especially audio streaming.Modul Bluetooth Low Energy is mainly used for low-bandwidth applications where data is frequently transmitted between devices. Bluetooth Low Energy dikenal karena konsumsi daya yang sangat rendah dan popularitasnya di ponsel pintar, tablet dan komputer pribadi.

Bluetooth Energi rendah dibagi menjadi point-to-point, star, mesh and broadcast topologies. Dalam topologi mesh, the nodes are directly connected without communicating with other nodes through the hub. Node dapat mengirim data dan informasi ke node lain di luar rentang komunikasi node sumber asli, expanding the network coverage in a large area.

Bluetooth technology Aplikasi

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 Jaringan Area Lokal Nirkabel Standar (WLAN). Pita frekuensi kerja Wi-Fi biasanya 2.4 GHz dan 5 GHZ ISM, Tetapi versi Wi-Fi yang lebih baru juga menggunakan pita frekuensi lainnya.

Wifi teknologi Technical Details

Ada banyak versi wi-fi. Aliansi Wi-Fi baru-baru ini mengadopsi sistem penomoran versi baru: Wi-Fi 1 (802.11B), Wi-Fi 2 (802.11A), Wi-Fi 3 (802.11G), Wi-Fi 4 (802.11N, Wi -fi 5 (802.11ac) dan wi-fi 6 (802.11kapak). Versi terbaru dapat memenuhi kebutuhan berbagai aplikasi, including longer distance, throughput yang lebih tinggi dan cakupan yang lebih besar.

The most popular topology for Wi-Fi is the star topology. Tapi di topologi bintang, node hanya dapat berkomunikasi satu sama lain melalui hub.

Wifi teknologi Aplikasi

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.
