Yesterday, we discussed how Bluetooth works/operates. Today, we are going to focus on the benefits that can be derived from using Bluetooth.

Listed below are 10 benefits of and reasons to use Bluetooth technology that you may not have thought of prior to reading this article:

1. Wireless Communication: It improves safety for the user of the device since the use of wires is eliminated. That means if you are traveling with your laptop or any other wireless device, you will no longer need to worry about bringing multiple connection cables for voice and data transfer connectivity.

2. Bluetooth is inexpensive: Bluetooth technology is cheap for telephone and other companies to implement, resulting in lower costs for the company. These savings are then passed on to consumers who end up paying less for Bluetooth devices.

3. Bluetooth is automatic: Bluetooth does not require you to set up a connection or push any buttons. Once two or more devices enter a range of up to 30 feet of each other, they will automatically begin to communicate without any intervention from the user.

4. Standardized protocol: Bluetooth has a standardized wireless protocol, which basically means that a high level of compatibility is guaranteed among devices. Bluetooth will connect devices to each other, even if they are different models.

5. Low interference: Bluetooth devices almost always avoid interference from other wireless devices. This is due to the fact that Bluetooth uses a technique known as frequency hopping (which was discussed in Part 1 of this article) and also uses low powered wireless signals.

6. Low energy consumption: As a result of Bluetooth using low power signals, the technology requires very little energy and will use less battery or electrical power. This is an excellent benefit for mobile devices since Bluetooth will not drain the battery of the device.

7. Sharing voice and data: The standard for Bluetooth allows compatible devices to share data and voice communications. This is great for mobile phones users who have headsets because Bluetooth simplifies the task of driving and talking on your cell phone at the same time.

8. Instant PAN (Personal Area Network): You can connect up to seven Bluetooth devices to each other within a range of up to 30 feet, forming a piconet or PAN. For a single room, you can also set up multiple piconets, based on the number of Bluetooth devices that you are using.

9. Bluetooth is upgradeable: The Bluetooth standard is upgradeable. There are newer versions of Bluetooth in the making which will offer many new features and advantages, allowing it to be backward-compatible with older Bluetooth versions while providing improved communication with newer devices.

10. The technology remains: Bluetooth technology is a wireless standard that is worldwide and universal. With it’s popularity where it is at present, you can count on it being around for many years to come. As more and more devices start to use Bluetooth technology, you will find that many more manufacturers will become increasingly eager to make their products Bluetooth compatible. This will result in a chain reaction that will make Bluetooth THE standard for cutting edge wireless devices and technology.

Simply put, Bluetooth is the way to go for the future!

This brings us to another question: What is frequency hopping? Well, frequency hopping is basically jumping from frequency to frequency within the ISM radio band. After a bluetooth device sends or receives a packet, both that device and the other device(s) that it is communicating with hop to another frequency before the next packet is sent. This set up offers three key advantages:

1. It allows Bluetooth devices to use the entire ISM band while never transmitting from a fixed frequency for more than a short period of time. This helps to ensure that Bluetooth conforms to the ISM restrictions on the transmission quantity per frequency.

2. It ensures that any interference will be temporary. Any packet that does not arrive safely to its destination can be resent to the next frequency.

3. It provides a base level of security as it is very hard for an eavesdropping device to predict which frequency the Bluetooth devices will use next.

The connected devices, however, must agree upon the frequency they will use next. Bluetooth specifications ensure this in two ways:

A. It defines a master and slave type relationship between Bluetooth devices.

B. Next, it specifies an algorithm that uses device-specific information when calculating the frequency hop sequences.

A Bluetooth device that operates in master mode can communicate with up to seven devices that are set in slave mode. To each of the slaves, the master Bluetooth device will send its own unique address and the value of its own internal clock. The information sent is then used to calculate the frequency hop sequences. Because the master device and each of the slave devices use the same algorithm with the same initial input, the connected devices will always arrive at the same time at the next frequency that they have agreed upon.

As a replacement for cable technology, it is no wonder that Bluetooth devices, like wireless mice and cell phones, are usually battery powered. To conserve power, most Bluetooth devices operate in low power, allowing them to have a range of around 5 – 10 meters. This range is far enough for wireless communication and close enough to avoid drawing too much power from the power source of the device.

Tomorrow we will continue with Part 2 as we look at the benefits of Bluetooth.
