 Bluetooth
is an industrial specification for wireless personal area networks
(PANs). Bluetooth provides a way to connect and exchange information
between devices such as mobile phones, laptops, personal computers,
printers, GPS receivers, digital cameras, and video game consoles
over a secure, globally unlicensed short-range radio frequency.
The Bluetooth specifications are developed and licensed by the
Bluetooth Special Interest Group.
Bluetooth is a standard and communications protocol primarily
designed for low power consumption, with a short range (power-class-dependent:
1 meter, 10 meters, 100 meters) based on low-cost transceiver
microchips in each device.
Bluetooth enables these devices to communicate with each
other when they are in range. The devices use a radio communications
system, so they do not have to be in line of sight of each
other, and can even be in other rooms, as long as the received
transmission is powerful enough. |

Range (approximate) |
Class1
|
100 mW (20 dBm) |
~100 meters |
Class 2
|
2.5 mW (4 dBm) |
~10 meters |
Class 3
|
1 mW (0 dBm)
|
~1 meter |

| In most cases the effective range of
class 2 devices is extended if they connect to a class 1 transceiver,
compared to pure class 2 network. This is accomplished by the
higher sensitivity and transmission power of Class 1 devices. |

| For Nietzsche wireless solution business
unit, we focus on industry control and automation application
instead of Personal Area Network (PAN). And every devices with
RS485 port can use BTX-150/ BTH-150 to transmit data. Nietzsche
Wireless Solution Team keeps searching for new solution to make
wireless safer and eliminate cost of cabling. |
