Bluetooth Headsets for Cell Phones

There are several ways that electronic devices may be connected to each other –

o Component cables

o Electrical wires

o Ethernet cables

o WiFi

o Infrared signals

The community of electronic devices that you have is made up of your computers, entertainment systems, telephones, and the various pieces and parts of the systems. Communication can be established between these devices using variety of wires, cables, radio signals and infrared light beams, including a wide range of connectors, plugs and protocols. Bluetooth is another art of establishing connectivity between these devices.

You need a Bluetooth enabled cell phone to have a wireless connection between your cell phone and your head set. For a better understanding of the advancement of technology, Bluetooth is an in-expensive way for different devices to communicate with each other, with the help of a secure, short range radio frequency. With this technology you can achieve up-to seven established connectivity at any one time, including cell phones, headsets, cameras, Global Positioning System (GPS) devices, printers, keyboards, handheld computers, and even Bluetooth-capable cars.

While using your mobile in your car, you would ideally have the Bluetooth connecting your headset with your phone, patched through your car’s audio system and your onboard navigation screen. Bluetooth establishes a connection between the devices. It has a range of 30 feet and uses the same frequency as wireless fidelity, or Wi-Fi, but does not reach near the distances. Wi-Fi also requires costlier hardware.

A Bluetooth headset is small and lightweight wireless device, with some models weighing less than 28gms. You can have 5 hours of talk time with this device and as much as 100 hours of stand-by time. The Bluetooth headset allows you to communicate through your cell phone in wireless mode, even if your phone is in a bag, your pocket, in a piece of luggage, or nearby in the room.

With the release of the newer versions of Bluetooth, it is important that you need to check that your Bluetooth headset and other devices are compatible. The previous version had problems like identity snooping and tracking, which has been resolved in the new version. It provides adaptive frequency hopping feature when it comes to crowded frequencies.

In choosing a Bluetooth headset, you should first check if the device is easy to put on and remove, and the comfort in wearing the device. The volume and other controls should be easy to use. It is also important to find out if the battery is replaceable and the number of devices that it can be connected with. You need to ask for the range of model available and look at the specifications. You should also want a clear, well-written, helpful manual for your Bluetooth headset. Bluetooth got its name from a 10th century Danish king who unified Denmark, Norway, and Sweden, and it has also some other catchy buzzwords. Bluetooth devices can be secured from eavesdropping and blue-snarfing from hackers, by a code, or placing it in the hidden mode when not in use.

Bluetooth has been designed to work in noisy environment. Here we are talking about electrical interferences which are also known as noises. These noises disrupt communication which you have often come across while having a conversation on your mobile phone. To eliminate such noises, Bluetooth uses frequency hopping technique. When a noise occurs in the frequency that it is operating in, Bluetooth typically hops into another frequency after transmit/receive of the current packet. This is to avoid interference from other signals. A microwave oven, for example, may be a source of interference and in such cases Bluetooth hops faster and uses shorter packets for transmit and receive, limiting the impact of the interference from other devices or electrical appliances.

The advantage of a Bluetooth is that it is a wireless device, which is inexpensive and automatic. There are other methods in establishing the same purpose as a Bluetooth, through wires, infrared communication, etc. Infrared (IR) is a very low frequency device, much lower than what human eye can see and a good example is its use in television remote control. Infrared (IR) has its advantage in having the feature that it needs to be lined up with the receiver in order to communicate, as you find in a television remote control. Even with a room full of IR devices, the one to one transmit and receive work without having any interference problems from any other devices.

Bluetooth uses multi-layer of data encryption and is extremely secure. With its user authentication measures, it is one of the secured communication links. The use of a Personal Identification Number (PIN) and a unique Bluetooth address, one Bluetooth identifies other Bluetooth devices. To further enhance Bluetooth security, data encryption technique could be used. By using frequency hopping, Bluetooth maintains the security aspect by not transmitting in one frequency within the 2.4 GHz band.

Bluetooth uses very low power, which saves the battery and takes small-area networking to the next level by removing the need for user intervention. Your cell phone connected to Bluetooth can receive the map from your GPS device in your car. This is automatically sent to your computer as your Bluetooth picks up a signal from your PC and automatically sends the designated data you requested for. Minutes later, your Bluetooth enabled landline starts to ring instead of your mobile phone. This call to your mobile phone got automatically routed to your landline because the Bluetooth found that you are home. It uses minimal power for each transmission to and from your mobile phone, and your phone battery charge remains virtually unaffected by this activity.

Bluetooth headsets. In 99% of the world the local cellular service standard is called GSM. We use this in the states as well. When combined with a SIM CARD (which usually goes under the battery of the phone) the phone is able to communicate and the SIM CARD also holds the telephone number and memory for pre-paid credit. Rates can be extremely low using this system. For example in 99% of all SIM CARDS incoming calls are free and calls to the states can cost a trifle. Such as, from the UK to the USA 7 cents/minute, from Israel 22 cents, from Australia 27 cents. Yes, USA Dollar cents! There are today even prepaid service providers in the USA offering rates of 10 cents per minute to call anywhere in the US to any type of phone. No contracts, no credit card checks, no bills. Pre-paid means no minimums no contracts, no obligations. You’ll need an unlocked GSM tri-band or quadband UNLOCKED phone.
