Technical information
Main article: Bluetooth (specification)
The Bluetooth specification defines a communication channel of maximum 720 kb / s (1 Mbps gross capacity) with optimum range of 10 meters (100 m optionally with repeaters).
The radio frequency with which you work is in the range of 2.4 to 2.48 GHz with broad spectrum and often breaks with the possibility of transmitting in Full Duplex with more than 1600 jumps / s. The breaks often occur among a total of 79 frequencies intervals 1Mhz, this gives security and robustness.
The output power to convey to a maximum distance of 10 meters is 0 dBm (1 mW), while the long-range version passed between 20 and 30 dBm (between 100 mW and 1 W).
To achieve the goal of achieving low consumption and low cost, was devised a solution that can be implemented on a single chip using CMOS circuitry. Thus, it was possible to create a solution 9x9 mm and it consumes about 97% less energy than a cell phone common.
The protocol banda base (single channel per line) combines circuit and packet switching. To make sure the packages do not arrive out of order, the slots can be booked by s
