A few years agao, I was walking around school and I saw this lady talking to herself. "The world is full of crazies," I thought to myself and continued on my oblivious way. I would soon learn later that she was probably using bluetooth. Sometime later, I learned of this advance technology called, "Blue Tooth." This technology is over my head, I thought to myself, and just push it aside. Unfortunately, I couldn't get away from it. Everywhere I went I was bombarded with adverstisements, screaming at me, "BLUETOOTH CAPABLE!" So I eventually gave in and was forced to learn about bluetooth.
Here are some interesting facts about bluetooth that I found on a website developers.sun.com:
-Bluetooth is wireless and automatic. You don't have to keep track of cables, connectors, and connections, and you don't need to do anything special to initiate communications.
-Devices find each other automatically and start conversing without user input, expect where authentication is required; for example, users must log in to use their email accounts.
-Bluetooth is inexpensive. Market analysts peg the cost to incorporate Bluetooth technology into a PDA, cell phone, or other product at around $20 now, and say that it could fall to as little as $5 per unit.
-Bluetooth handles both data and voice. Its ability to handle both kinds of transmissions simultaneously makes possible such innovations as a mobile hands-free headset for voice with applications that print to fax, and that synchronize the address books on your PDA, your laptop, and your cell phone.
Signals are omni-directional and can pass through walls and briefcases.
-Bluetooth uses frequency hopping. Its spread spectrum approach greatly reduces the risk that communications will be intercepted.
When I finally felt brave enough to use bluetooth technology, I programmed my ear piece to use blue tooth. I was completely in awe that I was using my phone without acutally holding it! The image of the "crazy" lady talking to herself appeared in my mind, and I found myself feeling quite foolish, that she was not crazy after all.
