Assignment 4.5
APPLICATION AREAS SUPPORTED BY BLUETOOTH
Being a wireless technology, Bluetooth allows exchange of data over short distance from fixed and mobile devices developing networks with high levels of security. It solves synchronization problems by connecting to multiple devices and so it is designed to operate in an environment of even up to eight devices in a network called piconet. Ten of the piconets exist within the coverage range of the blue tooth radio. Each link is encoded and protected from any interference or security risk.
- Data and voice access points. It facilitates transfer of both data and voice transmissions through provision of wireless connection for all devices regardless of whether they are portable for instance, mobile phones, and laptops as well as stationary devices like desktops. Blue tooth does not only enhance transfer of textual data but it also permits transfer of voice data like music.
- Cable replacements. Before introduction of this technology, one had to physically connect one device to another using a cable for data transfer but blue tooth eliminates use of cables because connection is wireless and can be maintained even when the devices are off the line of sight. Usually each radio covers approximately 10m but with the aid of optional amplifier, it can stretch even to 100m.
- Ad hoc networking. This application allows any device connected with blue tooth radio to establish connection with another that is within the range or area of coverage.
Personal security is another application that became operational from 2009; it is usually installed in mobile phones and help to prevent theft or loss of items. Protected item must have Bluetooth marker where an alarm is raised when connection between the phone and the item fails.
