Piconet<\/b> is a computer network which links a wireless user group of devices using Bluetooth technology protocols. A Piconet consists of two or more devices occupying the same physical channel (synchronized to a common clock and hopping sequence).<\/p>\n\n\n\n

\"\"<\/a><\/div><\/div>

It allows one master<\/i> device to interconnect with up to seven 7 active slave<\/i> devices. Up to 255 further slave devices can be inactive, or parked<\/i>, which the master device can bring into active status at any time, but an active station must go into parked first.<\/p>\n\n\n\n

Some examples of Piconet include a cell phone connected to a computer, a laptop and a Bluetooth-enabled digital camera, or several PDAs that are connected to each other.<\/p>\n\n\n\n

<\/span> How it works <\/h2>\n\n\n\n

A group of devices are connected via Bluetooth technology in an ad hoc fashion. A Piconet starts with two connected devices, and may grow to eight connected devices. Bluetooth <\/a>communication always designates one of the Bluetooth devices as a main controlling unit or master<\/i> unit. <\/p>\n\n\n\n

Other devices that follow the master unit are slave<\/i> units. This allows the Bluetooth system to be non-contention based (no collisions). <\/p>\n\n\n\n

This means that after a Bluetooth device has been added to the Piconet, each device is assigned a specific time period to transmit and they do not collide or overlap with other units operating within the same Piconet.<\/p>\n\n\n\n

Piconet range varies according to the class of the Bluetooth device. Data transfer rates vary between about 200 and 2100 kilo-bits per second.
Because the Bluetooth system hops over 79 channels, the probability of interfering with another Bluetooth system is less than 1.5%. <\/p>\n\n\n\n
