How does bluetooth ?
bluetooth technology uses the same small enough short-range transceivers exposure, they are either built into the device, or connect via the free port or a PC card.Bluetooth operates within a radius of ten meters, and, in contrast to the IR port, does not require a line-of sight, in other words, between the devices can be various barriers or walls.
essence of the Bluetooth
equipment using Bluetooth, have a functionality in the range of 2.45 GHz and can transmit data at speeds of more than 720 kbit / s over a distance of up to ten meters.If the device that receives the signal, determines that the distance to the transmitting device less than ten meters, it immediately changes the transmission power to the level required for a given location devices.The device switches to energy saving mode if the amount of data transferred will be small or the transmission will stop.
Bluetooth allows the connection of electronic devices and wireless connection through a small short-range, ad-hoc networks, called piconet.Each device can immediately belong to multiple networks.Such networks are established dynamically and automatically, asBluetooth devices enter and leave the link to the devices located in the vicinity.
Bluetooth with breakneck speed penetrates into all new areas of industry.You ask how the bluetooth on the laptop and on the phone?It is the same;technology has reached the point that the Bluetooth-chips are already in cargo containers to determine the load, or Bluetooth-chip built-in auto-bus for information about their condition or refrigerator, microwave oven with Bluetooth technology.All this is really true and real, and, apparently, have Bluetooth is large and bright future in the world of technology.
As you have read this article, Bluetooth technology is very useful and necessary in today's world of new technologies.Now you know how the bluetooth, so take your phone or laptop and go to the comprehension of the latest technologies.
