Our online glossary is here to help you make sense of the terminology used in the cell phone industry. It covers mobile technologies, such as 3G and 4G, and even includes a bit of information on smartphone operating systems and the companies that make the cell phones and other mobile technology devices we all use.
In order for two (or more) Bluetooth devices to be able to work together to accomplish a given task, such as file sharing, they need to both support the appropriate profiles. The Bluetooth SIG has defined countless profiles, such as Headset, A2DP Stereo, OBEX File Exchange, to name just a few. This is why devices such as Bluetooth keyboards are generally not usable with mobile phones - most mobile phones do not support the necessary HID Bluetooth profile.
