What is the Range of Bluetooth?
Bluetooth is designed for low power use. The standard range for Bluetooth devices is 10m (Around 33 feet). The 10m range is perfect for what Bluetooth was developed to do. Newer high-powered Bluetooth allows a range of up to and sometimes over 100m.

How Secure are Bluetooth Networks?
Bluetooth utilizes two types of security measures. First, Bluetooth uses frequency hopping (1600 hops/sec), which is added protection against eavesdropping. Next, there is a built-in security at the physical layer. This features allows one-way, two-way, or no authentication.
Security setup and key management are done by the software layers. This allows the user to set the security requirements as needed. Now, you are in control of the relationships between Bluetooth devices and networks.
For Example: you will be able to allow your roommate's computer to connect to your Bluetooth printer, but you can also prevent him from accessing your MP3 player.

What is BlueBugging?
Bluebugging allows skilled individuals to access the mobile phone commands using Bluetooth wireless technology without notifying or alerting the phone's user. This vulnerability allows the hacker to initiate phone calls, send and read SMS, read and write phonebook contacts, eavesdrop on phone conversations, and connect to the Internet. As with all the attacks, the hacker must be within a 10 meter range of the phone.

What is BlueSnarfing?
Bluesnarfing is the theft of information from a wireless device through a Bluetooth connection.
By exploiting a vulnerability in the way Bluetooth is implemented on a mobile phone, an attacker can access information -- such as the user's calendar, contact list and e-mail and text messages -- without leaving any evidence of the attack.
Operating in invisible mode protects some devices, but others are vulnerable as long as Bluetooth is enabled.
