Tiny little bit nervous but luckily we still manage to present our findings without any unexpectedness:))
Dr. Dayang continued her topic on the wifi technology which she taught us about bluetooth, broadband, and infrared.
Bluetooth was created basically to solve simple problem: replacing the cables used on mobile devices with radio frequency wave. This technology includes a simple low-cost and low-power global radio system.
Bluetooth works everywhere as long as it has the hardware that compiles with Bluetooth wireless specification to ensure communication compatible worldwide. This tech allows users bring connectivity with them anywhere they go such as Europe, Asia, America or other parts of the world.
So, how BLUETOOTH works?!
It utilizes a radio-based that does not require a line of sight connection in order to communicate. Hence, to establish a connection, 2 bluetooth equipped devices simply have to come within 10 meter range of each other. A device must request a connection either to accept or reject before communication can happen.
All Bluetooth devices can operate as both client and server. This happened due to the concept of the focus on point-to-point and point-to-multiple connection with small network called piconets. Each piconets hold up 8 active units.
Moreover, Dr. Dayang would like us to find about the future development of bluetooth technology. Hence, I found an article in the website of http://www.informit.com/articles/article.aspx?p=24243, the writer or the author mentioned that as Bluetooth wireless technology is incorporated in more personal mobile devices, it enables new uses for those devices. One such use is that of a mobile device as a method of payment for goods and services.
