					Wireless Headset Tutorial Wireless Headsets provide mobility to roam (within a 30 to 300 foot range from your desk) while on the phone. Without being tethered to your phone, you are free to move about your office while continuing to talk hands -free. GBH carries a wide array of wireless headset products. Selecting the appropriate wireless headset can be very confusing. This tutorial is designed to make this selection as easy as possible. While there are a number of models to chose from, the choices are rela tively straightforward because most of the products that are available are each designed to do one function very well, thus it is especially important to determine what criteria is most important to you. How to choose a Wireless Headset There are several points to consider prior to making a purchase. The key variables are: 1. Application – how are you going to use it? 2. Distance – how much range and clarity are required? 3. Price – how much do you want to spend? 4. Feature s – what features do you want and need? 1. Application   How and where you will use your wireless headset dictates which product you will select. Application issues include the following: Do you want a truly wireless headset? They are available as either completely wireless or with a headset that connects to a belt pack. o A completely wireless headset consists of a headset worn on your head that communicates with a base unit that attaches to your telephone with absolutely no wire between your headset and the phone. These headsets utilize the most sophisticated technology and are the most expensive. o Corded wireless headsets have a wire that connects the headset with a belt pack. The belt pack unit is independent of your phone and the communications link between the belt pack and the base unit attached to the phone is wireless. The term wireless headset generally means that it wireless from the belt pack to the receiving unit. These headsets are cost-effective and allow wireless mobility at a reasonable price. Do you need a wireless headset that works on a business or multi -line phone? If so, you are going to need a unit with an amplifier that is sophisticated enough to work with a variety of telephone sets. This is not a problem, most wired telephone headsets already work this way, but they do require a more sophisticated amplifier Do you need remote answer capability? If so, you need a handset lifter. Are there a large number of other wireless headset users in close proximity to you? If so, the number of users must be taken into consideration so that all users have access to a frequency and can have safe and secure communication.

2. Distance is a Function of Technology The operating distance is a direct function of the wireless technology used. Headsets are available that operate on different frequencies and come packed with many different features. All wireless headsets wor k on the same principle, by transmitting a signal between the headset (usually a belt -worn device) and the base station. The frequencies used to transmit vary in terms of range and clarity. The wireless technologies are:  Bluetooth™ o Bluetooth™ is a new, emerging wireless technology. Bluetooth™ is a wireless technology that has a specification for small-form factor, low-cost, short-range radio links between a variety of devices and it works particularly well with headsets. DECT o DECT (Digital Enhanced Cordless Telecommunications) is a flexible digital radio access standard for cordless communications in residential, corporate and public environments. DECT provides for voice and multimedia traffic, and contains many forward-looking technical features that allow DECT-based cordless systems to play a central role in important new communications developments such as Internet access and inter-working with other fixed and wireless services such as ISDN and GSM. According to the DECT Forum, the new logo for the US "DECT 6.0 - Interference Free Communication" indicates that DECT 6.0 performance is superior to 2.4GHz and 5.8GHz systems. The DECT technology can easily be integrated into WLAN systems without negative impact because DECT 6.0 resides in the UPCS band. The "listen before transmit"-standard avoids interference even when the spectrum usage increases. The rapid growth of WLAN and WiFi products supports the adoption of the DECT 6.0 technology in the US since the increasing proliferation of broadband services increases the interference in the ISM bands and affects therefore the demand for solutions like DECT 6.0. 
2.4 Gigahertz (GHz)

The most advanced wireless headsets use the 2.4 GHz frequency. This superior technology provides extremely clear cordless reception at the longest ranges possible. These headsets are the most expensive because of their outstanding performance and long range. It uses a more recently allocated frequency that is less crowded, more secure and less likely to have interference from other devices. If you want the best sound quality and the longest range you need a 2.4 GHz wireless headset. 900 Mhz o 900 MHz technology is a popular technology for wireless headsets. Wireless headsets that operate at this frequency are very cost effective and have good long-range performance. 900 MHz technology is widely used in co rdless phones and comes in both digital and analog versions. The latest version is digital 900 MHz technologies, which provides better transmission than analog because it transmits a digital signal less subject to interference. Digital 900 MHz also comes in a version known as 900 MHz DSS o

(digital spread spectrum technology). This technology spreads the signals over multiple frequencies that provide better security, noise reduction, and extended range. 3. Price The price of a wireless headset varies. Prices primarily correspond to the wireless technology utilized. The ability to answer or disconnect remotely requires the use of a hook-switch control device, which can also add to the cost of your wireless headset. 4. Features Important features include the f ollowing:  Ability to work on multi-line phones o Wireless headsets are compatible with most business phone systems. The wireless converter takes the place of the headset amplifier. Some of the wireless headsets plug directly into the wall jack. For information concerning compatibility please contact our Sales Department. Flexible headset style o Wireless amplifiers allow flexibility concerning the headset style. These products include just the wireless amplifier. The user is then allowed to choose the headse t style they prefer. Other wireless headset products are bundled in "systems." These products include the standard headset with the wireless amplifier. Maximum number of units o The number of other units can be used in close proximity varies depending on product and environment. In some situations, up to 50 units can be used in one area. For more information on the maximum number of units can be used in your application , please contact our Sales Department. Talk time/Battery life o Wireless headsets have a battery life of four to eight hours, depending on the product. Most wireless headset bases are equipped with an additional recharging area for an additional battery. By charging a battery while using the headset, battery life will not be an issue. Remote Dial Capability o Most wireless headsets do not have a dialpad to initiate outgoing calls while remote, they rely on the desktop phone to originate new calls. Remote answer capability o All wireless headsets let you take an already answered phone call and talk on your wireless headset. The most sophisticated wireless headsets let you answer calls remotely. They do this by using a Handset Lifter/Hook switch. These products allow you to answer calls away from your desk by a device that lifts the handset on your phone.
