Bluetooth® Communication


What is Bluetooth Communication?




Bluetooth wireless technology allows you to wirelessly connect compatible digital devices such as personal computers, digital cameras, mobile phones, and headsets. Communication is established by connecting two devices together, or sometimes simultaneously connecting multiple devices to one device. Depending on the power class used by the Bluetooth device the maximum range can be from 10-100 meters. However, most Bluetooth devices will have a range of up to 10 meters.

Before buying a new Bluetooth wireless technology enabled device, be sure to verify the compatibility with your existing Bluetooth wireless technology enabled devices. The devices to be connected must have the same Bluetooth communication profile. For detailed information on the connectivity of Sony® products, see the Sony online support page for each product.



Bluetooth Communication Ease of Use


In a few easy steps, you can connect compatible digital devices using Bluetooth wireless technology. Pair the devices to register and recognize each other. Some devices require a passkey input. Connect the devices for communication using Bluetooth wireless technology. Begin wireless communication between your equipment using Bluetooth wireless technology.


Bluetooth Communication Advantages


 
Low power consumption

Communication using Bluetooth wireless technology uses less power than a traditional wireless LAN connection. Because it requires low voltages, it is suitable for mobile devices that operate on batteries.


 
High-security

Communication using Bluetooth wireless technology has its own system of authentication and encryption to provide high levels of security for communication between connected devices. This helps prevent information from leaking to unconnected devices and establishes safe communication.
NOTE: Sony cannot guarantee the security of wireless communication.


 
No need for network construction

When using Bluetooth wireless technology, the devices connect directly to each other. Unlike wireless LAN, there is no need to set-up a network.



Glossary


Profile - A standard defining the specification of devices and the protocols for communication using Bluetooth wireless technology. The devices to be connected must have the same profile. Click here for a list of Bluetooth communication profiles.

Paring (registration of devices) - Prior to communication using Bluetooth wireless technology, the devices must be registered to enable connection.

Passkey - A number used for identifying a Bluetooth wireless technology enabled device and authenticating a connection. This may also be called a passcode, PIN code, PIN number, password, or authentication code.

Notes on using Bluetooth wireless technology enabled devices


The 2.4 GHz band used by Bluetooth wireless technology, is a band shared by various devices including wireless LAN devices IEEE802.11b/g. Bluetooth wireless technology enabled devices are designed to keep the influence of other devices in the same spectrum to a minimum. However, the influence of other devices may cause the communication distance and/or communication speed to be reduced, or communication to be cut off.



In the following cases, the communication distance may be reduced:

  • When there is an obstacle such as a human body or a wall between the devices connected by Bluetooth wireless technology.
  • In a location where a wireless LAN is established.
  • Near an operating microwave oven.
  • Any other locations where electromagnetic waves are generated.
