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 frequency band. Over the years, Bluetooth technology has continued to expand, 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

वर्तमान में दो अलग -अलग ब्लूटूथ रेडियो विकल्प हैं: ब्लूटूथ क्लासिक और ब्लूटूथ कम ऊर्जा (ब्लूटूथ ले). क्लासिक ब्लूटूथ (या br/edr), मूल ब्लूटूथ रेडियो, स्ट्रीमिंग अनुप्रयोगों में अभी भी व्यापक रूप से उपयोग किया जाता है, especially audio streaming.Bluetooth Low Energy module is mainly used for low-bandwidth applications where data is frequently transmitted between devices. ब्लूटूथ लो एनर्जी को इसकी बेहद कम बिजली की खपत और स्मार्ट फोन में इसकी लोकप्रियता के लिए जाना जाता है, गोलियां और व्यक्तिगत कंप्यूटर.

Bluetooth Low Energy is divided into point-to-point, star, mesh and broadcast topologies. In the mesh topology, the nodes are directly connected without communicating with other nodes through the hub. Nodes can send data and information to other nodes outside the communication range of the original source node, expanding the network coverage in a large area.

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

वाईफ़ाई तकनीकी

वाईफ़ाई तकनीकी Definition

Wi-Fi is the brand name of all IEEE 802.11 standard wireless local area networks (डब्ल्यूएलएएन). The working frequency band of Wi-Fi is usually 2.4 GHz और 5 GHz ISM, but newer versions of Wi-Fi also use other frequency bands.

वाईफ़ाई तकनीकी Technical Details

There are many versions of Wi-Fi. The Wi-Fi Alliance recently adopted a new version numbering system: वाईफ़ाई 1 (802.11बी), वाईफ़ाई 2 (802.11ए), वाईफ़ाई 3 (802.11जी), वाईफ़ाई 4 (802.11एन, Wi -Fi 5 (802.11एसी) और वाई-फाई 6 (802.11कुल्हाड़ी). The latest version can meet the needs of various applications, including longer distance, higher throughput and larger coverage.

The most popular topology for Wi-Fi is the star topology. But in the star topology, nodes can only communicate with each other through the hub.

वाईफ़ाई तकनीकी आवेदन

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.
