Working Of The First Car Phone

The story of the working of the first car phone is quite interesting as we look deep into the invention of mobile phones.  It was not an easy task to install such a machine in a car and to assure smooth functioning. A high level of expertise was needed to do this task. In this article, we will try to see how the first car phone used to work.

Early Working Of Car Phone

The earliest car phone was a fun project that was not made in a lab or any workshop. But it was made by a retired telecommunication expert. These phones were used widely used by the armies in the second world war. The device that was used by armed forces can be said as the predecessor of the modern wireless set. the difference between police wireless and telephone is important to distinguish here. The wireless set works on a particular set of networks with a set of signals. But the telephone work with a discrete set of signals and work with a larger set of networks.

How Car Phones Used To Work?

After the war when the large population of the United States of America started to displace at many remote places the need for a means of communication increased. The car phones were proven to be a great option for an area where the telephone networking was not available. The brand-new phone was used to be installed under the space near the cabinet of the car. Sometimes the bigger machines like the one of the Motorola’s used to be installed at the back of the car.

There were mainly three components of the car phones. The first one was the typical receiver that we all have seen. The second components were the transmitter and the third one was the antenna itself. The phone receiver was installed where we now have our music systems in the car. This was handy and the driver was able to pick the call as soon as he got one.

Technical Specification

The first company that made a commercial was western electrical. It was one of the biggest car phone companies of that time and a trendsetter in these technologies. Motorola came into the market after few times. Mobile telephone equipment had already been in use internally within the Bell System on an experimental basis, going back before World war II, using mobile radios such as the Western Electric Type 28 VHF equipment. One example was the Emergency Radiotelephone Service established by New York Telephone in December 1940, which used AM on the 30-40 Megacycle band.  Based on the successful tests of that equipment, AT&T announced the creation of the General Mobile Radiotelephone Service on June 29, 1945. This was a great jump in the invention of the mobile phones.

The Journey Ahead

Car phones have seen a very bright future after the launch it used to work in a large part of North America whether it is New York, Chicago, Montreal, or Toronto. Its publicity made it popular on the other side of the Atlantic. This invention of the mobile phone cannot be said as the first portable mobile phone. But it was a great step as the first car phone.
