What is Bluetooth?
Bluetooth technology is a short-range communications technology for wireless personal area networks (PANS). Quite simply Bluetooth creates a short range network that is accessible by all devices using the Bluetooth protocol. It enables the connection and exchange of information between bluetooth enabled devices allowing a person to have a phone conversation via a headset, use a wireless mouse and synchronize information from a mobile phone to a PC, all using the same core system.
The Technical Part
A Bluetooth transceiver operates in the unlicensed but secure ISM band centered at 2.4 gigahertz, (between 2.402 and 2.480 GHz) the same frequency range used by microwaves, radio control cars and Wi-Fi systems. The core system employs a frequency-hopping transceiver to combat interference and fading. With some equipment using the technology, it is easy to imagine devices interfering with one another. Bluetooth avoids this by using a technology called Spread Spectrum Frequency Hopping, which reduces the chance of two devices using the same frequency. The frequencies are randomly chosen within the 2.4 GHz, and they change regularly to limit the chance of interference.
When Bluetooth devices are within range, a conversation between them occurs to determine whether they have data to share or whether one will control the others. It is an automatic process. Bluetooth devices use a personal area network or Piconet. Once a Piconet is established, the frequencies of the device members hop frequently and simultaneously to keep in touch with one another and to avoid other Piconets that may be in operation.
Why use Bluetooth?
Bluetooth is attractive because it is wireless and relatively inexpensive. It is also automatic. Older communication devices needed to agree on a number of points before the conversation could begin. The first point of agreement is physical: Will they talk over wires, or through some form of wireless signals? If they use wires, how many are required -- one, two, eight, 25? Once the physical attributes are decided, several more questions arise regarding the protocol of how the information is passed between the 2 points.
When Bluetooth is used, the devices agree on several matters before the conversation can begin. Bluetooth provides agreement at the physical level because it uses the radio frequency standard, and provides agreement at the protocol level, where devices agree on the amount of data to be sent, how much data will be sent at a time, and whether the devices in a network can tell whether the message sent is the same as the one that was received. Bluetooth can also be used by many devices (up to eight devices) at the same time.
Is Bluetooth right for me?
A Bluetooth communication devices are ideal for bike intercom systems. They are secure, reliable and powerful enough to allow you to communicate with other riders that are within your range. If you want an intercom to just chat with fellow bikers or a passenger or you need to communicate for professional or business reasons then bluetooth technology is ideal.
