This paper will look at the Bluetooth technology and its compatible devices. It will seek to analyze the Bluetooth technology, its application, technology and its advantage over the other technologies.
Bluetooth technology is applied in a variety device which means that it need to have a compatible device in order to harmonize the technology. It has been show that each Bluetooth device can connect with up to seven other devices using a single Piconet. The device can also use several Pico nets at the same time. Piconets are well stabilized automatically and they are quite dynamic which means that they can be used in a number of other devices. The Bluetooth device therefore helps deices to be connected and disconnected with radio proximity.
Blue tooth device have been used to handle transmission of data and voice at the same time. This makes it earlier to the use of the devices to perform these multiple tasks at the same time. As a result the use can enjoy other services like hands-free voice calls, printing, synchronizing PDA, laptop and application from a mobile phone
There are many advantages and disadvantages of using the Bluetooth device. ...
Therefore it allows one to transfer data from one device to another.
Bluetooth device is also cheap to use. This is because it Bluetooth technology is easy to use and cost less. The evolution of the technology has revolution the communication technology and therefore massive investment in the production of the devices has made it affordable to many people.
One disadvantage of using the device comes in the fact that it has been found out that it is possible to connect the device without the knowledge of the use and therefore gain access to their data without their consent. In this regard it can be used to gain access to data stored in other devices. Therefore this has been considered by many as immature technology based on ethical issues of privacy of information.
Bluetooth software
At the core system definition, of the core system covers all the four layers and other protocols which are defined by Bluetooth including other specifications. It also cover the service discovery Protocol (SDP) and the Generic Access Profile (GAP). In order for a Bluetooth application, there must be other addition services and some high layer protocols which are all defined in Bluetooth specification.
The lower three layer are grouped to a system known as Bluetooth controller. This represents a common implementation which involves a standard physical communications interface between Bluetooth controllers that he others Bluetooth system like L2CAP and service and higher layers which presents the Bluetooth host. (Wong, Stajano and Clulow, 2005)
