Bluetooth-802.15
Bluetooth is a telecommunications industry specification that describes how mobile phones,
computers, and personal digital assistants
can be easily interconnected using a short-range
connection. Using this technology, users of cellular phones, pagers,
and personal digital assistants can buy a three-in-one phone that can double as a portable
phone at home or in the office, get quickly synchronized with information in a desktop or
notebook computer, initiate the sending or receiving of a fax, initiate a print-out, and,
in general, have all mobile and fixed computer devices be totally coordinated.
Bluetooth requires that a low-cost transceiver chip be included in each device.
The tranceiver transmits and receives in a previously unused frequency band of 2.45 GHz
that is available globally (with some variation of bandwidth in different countries).
In addition to data, up to three voice channels are available.
Each device has a unique 48-bit address from the
802 standard. Connections
can be point-to-point or multipoint. The maximum range is 10 meters. Data can be
exchanged at a rate of 1
per second (up to 2 Mbps in the second generation
of the technology). A frequency hop scheme allows devices to communicate even in
areas with a great deal of electromagnetic interference. Built-in encryption and
verification is provided.
The technology got its unusual name in honor of Harald Bluetooth, king of Denmark in the mid-tenth century.
