This write up is about the cordless telephone. It tells of how it came into existence and the people involved in its creation. It also compares the cordless with the corded phone, by listing some pros and cons in owning and using such a communication device.
Cordless telephones, as the name suggests, are not connected to the telephone network by a fixed line, instead they have what is called a base station which itself is connected to the network, and the handset sits in this when not in use. Communication by the handset with the telephone network is achieved by the sending and receiving of radio waves.
History and invention – the first cordless telephone was created by one Teri Pall in 1965. her phone had a range of 2 miles, which tended to interfere with the radio communications between aircraft, and as a result could not be put into use. one year on, and one George Sweigart from Ohio, USA, successfully invented a version of the phone that could be used without fear of interference with aircraft radio communications. Sweigart has been officially recognised as the inventor of the cordless telephone, because his version could be used commercially.
Benefits of being cordless – These types of phone allow for greater movement around the house or office, due to the fact that they are not tethered by a line of wire. If for whatever reason you are unable to leave an area (cooking, working on a vehicle, etc), you can keep the cordless telephone at hand, as it does not have to stay in its cradle when not in use. This is a major advantage over a telephone with a cord. one last advantage is that it is a lot easier to take and use a cordless phone outside of the property, as there is no fear of entangling a wire. You are also not limited by the length of a wire for how far away from the property you can go, but of course there will be a limit on reception. Of course, this applies to landlines, not mobile phones.
The cons of going cordless – one disadvantage of the cordless phone, is that it needs to be powered by a battery, thus requiring constant recharging, and regular replacement when the battery has reached the end of its life. Luckily, regular and consistent advancements in battery technology have resulted in batteries with a greater lifespan and being able to hold a charge for longer periods of time.
In conclusion – the cordless telephone was a ground breaking piece of innovation back in the 1960′s. one of the first electrical devices to be free of a cord of any kind, whether for communication or power. Today (2010), it has become the norm for tools, gadgets, and appliances to be free of any tether (wireless), and in some cases not even requiring the device to be held or controlled by any kind of physical interaction (Xbox Kinect). what will the future bring?
