With the expected deployment of Bluetooth devices in the next five years, it is imperative that managers of Bluetooth networks have a way to collect and analyze the usage patterns of their networks. Currently, Bluetooth networks simply operate without any effort by a central unit or operator. However, there are limitations, namely the finite capability for connections between each other. Our product enters the picture by yielding the information necessary to make judgments on network needs. We introduce the Bluetooth Diagnostic Interface (BDI).
The BDI utilizes network information available from the Bluetooth modules to ascertain and communicate piconet status to a website. The network manager can gather information on a certain master or slave by asking for its ID string in a query box on the website. This provides the ability to efficiently match supply of Bluetooth units with the demand as well as match the transmitted information with the needs of the user by analyzing their tendencies. The possibilities are endless.
To be prepared for increased Bluetooth network traffic there has to be a quick and easy means to monitor traffic trends and load. Our BDI elegantly offers this network monitoring functionality though the convenience of the Internet.
Bluetooth is a wireless communication standard/system operating in the 2.45 GHz ISM band with 79 frequency channels. Bluetooth uses low-power and low-cost units employing frequency hopping to make the system more robust. Devices exist in a dynamic master-slave relationship. There is only one master in every piconet (a piconet is a Bluetooth network). Upon entry to a piconet, the slave adjusts its clock to sync with the master’s and the master then determines the hopping sequence. These units can have a nominal 10 meter range or an extended 100 meter range when amplified.
Figure 1 provides an example of the basic connectivity between devices for our proposed solution. It shows a slave connecting to multiple masters in separate piconets. The server will communicate with users, via the Internet, to transmit the acquired
