A cordless telephone (telefone sem fio) is an electronic telephone that comprises of a wireless handset and a base unit. Communication is carried out between the handset and the base using radio waves. The wireless handset can be operated only within a fixed range from its base unit. The range of operation is generally within 100 meters. The base unit needs electricity to power it. Batteries are used to power the cordless handset. Placing the cordless handset in the cradle in the base unit recharges these batteries. A period of 12 to 24 hours is required for recharging the batteries.

With features like cell handover, data transfer and international roaming (on a limited scale), the once clear-cut line between mobile telephones and cordless telephones (telefone sem fio) has now been blended by the modern cordless telephone standards.

Frequency bands have been assigned in each country for cordless telephones (telefone sem fio). Advertisements by manufacturers claiming that there is an improvement in audio range and quality with higher frequency are a common sight. But that is not the case. Actually, higher frequencies have been seen to exhibit worse propagation in ideal case. There is also a tendency for the path loss to increase with higher frequencies. Locally varying factors such as antenna quality, signal strength, the modulation method being used and interference are more influential than other factors.

With Landline telephones working on a bandwidth of about 3.6 kHz (a small fraction of the frequency that a human ear can interpret), the transfer of audio is carried out with an audio quality that is just enough for the parties to communicate each other. Because of this limitation in the design of the phone system itself, it is not possible to improve the audio quality beyond a particular limit in cordless telephones.

Most of the good-quality cordless telephones (telefone sem fio) try transferring the audio signal with lowest possible interference and greatest possible range. Even the best of the cordless telephones fail to match the audio quality that a high quality phone wired to a good telephone line provides.

Sidetone (echo of voice heard in the speaker of the receiver), disturbing constant background noise that is due to the cordless system, and inability to obtain a full frequency response that is available in a wired phone are few of the reasons for a not-so-good audio quality. Rare exceptions, obviously, always exist that sound unbelievably similar to a wired telephone. But even these are considered as `fluke` by most industry standards.

Higher frequency is now being used in other home products like the microwave oven, Baby monitor, Bluetooth, wireless LAN, etc. Thus, cordless telephones (telefone sem fio) using higher frequency may face interference from signals from these devices.

Eavesdropping is a constant security threat for analog telephones. Any one with a radio scanner and within range can pick up these signals and listen to conversations. Modern digital technology is thus being used to take care of this kind of unauthorized access.

DSS (Digital Spread Spectrum) makes use of frequency hopping, i.e. spreading up of audio signal over a wider range in a pseudorandom fashion. DSS signal sounds like noise bursts to a radio scanner or any other analog receiver. This signal makes sense only to that base unit which has the same pseudorandom number generator as the cordless handset. Each time the cordless handset is returned to its cradle, a new unique generator is chosen from thousands of options.

DSS generates a signal spread that leads to a kind of redundancy, which gives rise to increased signal-to-noise ratio. It also leads to increase in signal range and decreases interference susceptibility. It is easier to use this kind of wide-bandwidth security option with higher frequency.

Conversing on the telephone is part and parcel of daily life. Unfortunately, sometimes it happens that there is loss of voice clarity because of background noise, whether at home or in the office. This can be a source of constant frustration while talking on the phone, especially if you cannot hear the person on the other end. However, if you use a headset attached to the telephone, you can eliminate a lot of background noise and clutter, thus making conversations between two parties easier. The earlier models of headsets may have been clunky and not user friendly, but the newer headsets are so easy to get used to that you will even forget that you are wearing one.

There are quite a few benefits of using a headset with a telephone. For one, it leaves your hands free, so that you can use do other work whether it is writing or using the computer. For the other it cuts the chances of getting shoulder and neck pain which would have been a possibility if you were using the old style receiver cradled between the shoulder and the neck. The other plus point of using a headset with a telephone is that you are using technological advancement to help you function better.

For those who earn their livelihood by using the phone such as telemarketers and call center employees, the headset is a necessity. It makes telephone usage that much more comfortable and convenient and thus adds to productivity.

Increase Your Business Conveniently And Easily

If you are a home worker, you can cut out the daily noise of everyday life whether it is a muted television in the background, the sound of children playing or even traffic sounds, by using a phone headset. This makes for a more professional sounding environment besides being more convenient and easier to use. Headsets which come with built-in noise reduction filters will reduce or remove background noise, thus allowing a person to work comfortably.

Newer cell phone and landline phone models have built in sockets so that you can attach a headset and make them hands-free. Some phones also include voice dialing facilities, so the user does not have to physically dial a number or even pick up a receiver.

So comfortable and convenient are headsets among business users, that most of them have started using them with their landlines at home as well. This gives them greater freedom of movement while talking on the phone, instead of being tied down to one place while using a phone.

When you use a normal phone it can be difficult to use if you are holding it to the ear with your hand, as your one hand is occupied. Even if you have to write down any note or information and even if you have paper and pen handy, it is not an easy task to do so, unless you are sitting at a desk. But if you use a phone headset, you will not face this problem at all. If you have to cradle the phone between your ear and your shoulder for any length of time, you will find it painful, but this is often what happens, even if you use a cordless phone, if you have to answer a doorbell or do anything else, while speaking on the phone.

While the earlier phone models were bigger and looked quite cumbersome, they were easier to hold and talk as the mouthpiece actually reached the mouth. The newer and more modern phones, even the cordless ones, are small and look good, but the speaker does not reach the mouth, and sometimes they are quite uncomfortable to talk into. A phone headset takes care of these difficulties. There are different models of phone headsets available. One of them has a separate mouthpiece and earphone, whereby the earphone is built into something like a headband and the mouthpiece is adjustable so that it can actually reach your mouth, plus it has the comfort of being hands-free.

Another model of a phone headset is one that has the speaker and the microphone in one and it fits in or around the user’s ear. This is not only convenient to use, but also gives a better quality of sound as it incorporates sound reduction techniques. Since there are different models of phone headsets available, you can find one which will suit you and be user friendly.

Check The Connection Points Of Your Phone

It is vital that you check the connection points of your phone, because the phone headset you buy must go into a socket in your phone. While a phone headset may be equipped with wireless technology, the telephone must be compatible with the wireless technology and the cheaper instruments may not be having the required technology or socket available. However, mid range to higher price point phones will usually come equipped with the technology.

Cell phone usage by a person driving a vehicle is illegal in many countries, but if a person uses the same through a cell phone headset, then it become hands-free and may be allowed. However, do keep in mind, that talking on a cell phone while driving is not without its risks, as conversation is a distraction to smooth and safe driving. Indoors, at home or in the office, a phone headset is easy to use and you do not have to carry the phone receiver around either.
