Bluetooth technology is a short-range radio communication which is wireless, low power and low cost. Bluetooth wireless technology is reshaping the definition of what wireless is mean to be. Unlike WiFi technology, Bluetooth technology uses radio waves to connect to other devices in short range wirelessly.
This technology steer the course to the future of our world connection. The core of Bluetooth technology lies in a low cost 9 mm x 9 mm microchip functioning as a short-range radio link when inserted into an electronic device, enabling Bluetooth capabilities for the device. The bluetooth-enabled devices communicate wireless between each other using these radio links, instead of via cables as used in normal connection. Since radio signals are omni-directional and can be transmitted through walls and other obstacles, Bluetooth-enabled devices don’t need to be in line of sight or be pointing at each other.
To make Bluetooth connection robust and secure, the technology avoids interference from other signals by leaping to a new channel every time it transmits or receives a data packet. Each device can simultaneously communicate with up to seven other Bluetooth-enabled devices within a single personal area network. Each device communicates with each other through a defined device name so that each device can keep track of who it is communicating with. The device name to use when you are setting up your Bluetooth device is typically cleared stated in the attending device documentation.
Bluetooth technology offers security protection with 128-bit built-in security encryption and PIN code authentication. The technology specification is available free-of-charge to Bluetooth member companies all around the world. Bluetooth wireless technology is commercially available in a wide range of applications such as bluetooth cellular phones, game devices, cars, medical devices and many more. The technology can also be used to transfer images, files, and even MP3 files between bluetooth cell phone or between MP3 players/digital camera and bluetooth enabled computer.
Limitations of Bluetooth Wireless Technology:
• Short communication range (up to 100 m)
• Lower data transfer rates compared to other wireless communication technologies
• Vulnerability interference from other devices operating in 2.4 MHz band.
Benefits of Bluetooth Technology:
• Wireless technology will give you many advantages such as convenience and safety
• Bluetooth technology is low-cost and affordable wireless technology for companies to implement
• Bluetooth high level of compatibility will simply connect bluetooth-enabled devices to each other, even if they aren’t the same model
• Using frequency hopping technology, Bluetooth devices constantly avoid interference from other wireless devices
• Bluetooth wireless technology uses low power consumption.
• If you want to, bluetooth can be fully automated. When two or more devices enter a range of up to 30 feet of each other, they can certainly begin to contact each other without you having to do anything.
