How Bluetooth Technology is Applied to Cell Phones
Have you ever been grocery shopping and seen someone talking to the heads of lettuce? Or have you seen someone at the video rental store and it has seemed as though someone was having an intense discussion about what movie to bring home...when they're the only one there? Yes, you could be watching someone "special", having a moment, but these days, it's more likely that the person was simply speaking to someone else on a Bluetooth device that you just didn't notice.
Bluetooth is a type of device that connects to other compatible devices - such as a cell phone - by using short-range radio signals. Its technology is becoming extremely widespread as a large part of the market has been cornered by its unique abilities - especially in its affordable way.
As small as one of these devices is, it is also very complex, and to fully understand it, you'd need quite an advanced engineering degree. Essentially, though, it provides a sort of universal standard for short-range wireless communication. Through the creation of this standard throughout the industry, many different manufacturers are able to create similar mobile devices that can all be used interchangeably and compatibly by the public. This is important because these devices aren't typically sold in sets. Instead, they need to be able to function along with devices of different types and brands.
It should also be noted that Bluetooth and Wi-Fi are not the same, even though they do both operate using the same 2.4GHz frequency. This is where the similarities end. Bluetooth doesn't have the data speeds or long range that are offered by Wi-Fi devices such as wireless routers. However, pairing and synchronization between Bluetooth and other units is much simpler than it is with Wi-Fi-based devices. Since Bluetooth headsets don't require a great deal of distance or data transmission to and from the device with which they are functioning, the technology is virtually ideal.
This being said, Bluetooth technology is always evolving and is improving with each successive generation. It allows us to appreciate the benefits of our cellular phones without busying our hands, making it easier to walk down the street, work at a desk, use the computer, or do anything else while talking on the phone.
