CIT112 – Chapter 5 Lab
Bluetooth is a pretty useful protocol that can be used by mobile devices to do many different things. Bluetooth has a much longer range than IRDA, and supports higher speeds (and is also not line-of-sight). So Bluetooth has replaced IRDA for most of its tasks. Here are some of the most popular uses of Bluetooth:
- Transferring small files
- Sending contact information
- Synchronizing computers with mobile devices
- Connecting keyboards/mice to computers
- Connecting mobile devices to Bluetooth headsets
Small amounts of money might be saved by using Bluetooth to transfer contact information, because paper business cards would not have to be purchased. Most traveling sales/business people will already have a device that supports Bluetooth.
The biggest advantage is probably that it is more convenient for the person receiving the information. They don’t have to input the information from the paper business card into their mobile device. This could reduce accidental errors. And assuming that they synchronize their cell phone/PDA with their computer, the contact information will automatically transferred to their computer. People are also less likely to lose their cell phone/laptop than they are to lose a small piece of paper that they stuff in their pockets.
The disadvantage of using Bluetooth to transfer contact information some people may still not have a mobile device. So, having a few paper business cards just in case could be a good idea.
