Speed; Communication Range And Power; Bluetooth Standard - Sony PCGA-BM1 Bedienungsanleitung

Speed

Bluetooth communications support a maximum data transfer rate of
723 kbps, but actual data transfer rates will vary, depending on factors such
as distance and obstacles between devices, radio interference, the operating
system or the software used, as well as equipment sensitivity and the
performance of the aerial. Data transfer rates are optimized to achieve the
best throughput under a given set of conditions.

Communication range and power

Bluetooth compatible devices are divided into several categories. Power
Class 1 devices can communicate over a line-of-sight distance of 10 - 100
*
metres . Power Class 2 or 3 devices can communicate over a direct distance
of less than 10 metres
* This assumes that no obstacles are present.
The actual range will vary, depending on factors such as the presence of obstacles
between devices, radio interference, the operating system or the software used, as well
as the equipment sensitivity and the performance of the aerial.

Bluetooth standard

In order to facilitate communication between Bluetooth compatible devices
from various manufacturers, the Bluetooth SIG has worked out standards
regarding wireless transfer methods, security implementation, application
specific data formats, etc. All Bluetooth compatible devices must be
certified according to procedures approved by the Bluetooth SIG to make
sure that applicable standard requirements are met.
However, even if standard requirements are met, individual device
performance and specifications as well as operation procedures vary, which
means that data exchange may not be possible in all cases.
