Bluetooth
In essence, Bluetooth is primarily a technology for replacing wires and cables, allowing you to connect to a wide range of devices. Experts note the following advantages of Blue Tooth: ease of use, communication of various devices (PCs, laptops, smartphones, keyboards, speakers, headphones, sensors and other gadgets), high connection stability, low power consumption. To use on a PC, you need to download Bluetooth for Windows 11, 10, 8, 7, XP from the site https://www.bluetooth.today/en/downloads using a direct link. The weaknesses of Bluetooth wireless technology include: limited range - a maximum of 600 feet, and indoors 30 feet, work in a stereo pair, which is problematic for home theaters, a decrease in the quality of the audio signal due to compression.
Bluetooth capabilities
The basic of Bluetooth is the basic specification 5.x with a real speed of 2 Mbps (theoretically up to 24 Mbps), a radius of up to 600 feet, and a wireless connection of up to 5000 feet for some devices in BLE mode. Improved energy efficiency, connection reliability and functionality (LE Isochronous Channels, LE Audio, LE Power Control, EATT), location and direction determination, channel classification, protocols and encryption. Bluetooth 5.x retains full compatibility with previous versions.
Bluetooth allows smart devices to exchange information over short-range wireless channels over short distances. Some modifications of Bluetooth Low Energy (for example, LPWAN, LoRaWAN, RFID-IoT and others) can work over significant distances, especially in combination with GSM gateways. Bluetooth, a low-cost wireless technology for personal area networks (WPAN), enables data exchange between two or more devices, from desktop PCs and refrigerators to keyboards and biometric sensors.
The site https://wirelesstechnology.site is dedicated to wireless technologies and devices for industry, agriculture, services, and home use. Wireless keyboards, mice, headphones, microphones, speakers, MFPs, printers, scanners, and many other office and home smart equipment exchange data with smartphones, tablets, laptops, and personal computers using Bluetooth. There are smart Bluetooth locks for entrance doors, sneakers, sports jackets, exercise machines, and a variety of sports and medical portable devices equipped with a Bluetooth chip, such as the Puma RS-Computer sneakers from the 80s with Bluetooth 4.0.
Bluetooth Low Energy wireless technology and its modifications
Navigation in huge entertainment, retail, warehouse spaces is based on Bluetooth Low Energy wireless technology, which allows you to accurately find the location of a person or thing in a huge three-dimensional space. For example, when a waitress brings your remote order to a distant corner of a huge multi-level restaurant, this is not her advantage. The secret lies in special Bluetooth Low Energy beacons and LPWAN, LoRaWAN, RFID-IoT and other technologies. Beacons are often used to optimize customer service, improve business efficiency, and provide discounts or promotions to regular customers. Beacons are also used to monitor the movement of personnel to improve work efficiency, automate warehouse accounting, and replenish stocks. Another area of application is tracking an order and the location of a courier in real time through a mobile application.
The Bluetooth LE wireless technology with low energy consumption turned out to be so good and in demand that its highly specialized modifications very quickly appeared for industry, agriculture, the service sector, and for home use.
Comparison of Bluetooth and Wi-Fi
Unlike Bluetooth, Wi-Fi wireless technology is not used for direct connection of devices, but for access to various networks, including the Internet. Transmission and reception of information and sound over a secure channel is not the limit for Bluetooth; you can quickly and inexpensively create a Wireless network Piconet or Scatternet, peer-to-peer or with a dedicated server, connect to local resources located within the range of the radio signal, organize an Internet access node. A Bluetooth wireless network can also unite devices located nearby into a local network, but a Wi-Fi network in similar conditions will be better in most respects. IEEE 802.11 a/b/g/n/ac/ax wireless technology offers greater bandwidth and a greater range than a Bluetooth wireless network. Wi-Fi technology, breaking the signal into parts, transmits packets over different radio frequencies. This makes it possible to transmit large amounts of information at high speed.
