Telecommunications Technological Revolution (The Science of Telecommunication Engineering)


Telecommunications Technological Revolution (The Science of Telecommunication Engineering)
It can connect you to anybody anywhere. Through a network that spans the globe, steeped in controversy when invented, it’s now a lifeline, an entertainment hub and an unparalleled tool for human interaction. But privacy isn’t assured.
Undeniably essential to modern life, the telephone is the most important, influential, and effective communication tool ever developed. Witness this invention’s unbelievably dramatic true story – one of false starts, close calls, and a bitter rivalry.
The development of the telephone has changed the way we live, and how we communicate with each other. This documentary takes a look at the history of Alexander Graham Bell’s remarkable innovation, offering some startling insights into how the telephone became such a commonly used object. Among the revelations are facts and figures about Bell’s original design, and how he almost lost out in the race to patent his invention. Also included is a look at how the use of the telephone has developed over the years, especially in relation to the internet.

All his life, Alexander Graham Bell was driven by a desire to create a machine that would make it easier for the deaf to speak and hear. Using an actual human ear from a cadaver to understand the nature of sound, Bell even enlisted a young Thomas Edison to help invent what would become the telephone.

Exploring how one man’s speaking device has grown into the technological web that links humankind, this thrilling program also revisits the race between Bell and rival Elisha Gray – who was building a similar design but ultimately filed the history-changing patent just two hours after Bell.
Some of the historical developments of the first telephone, as well as the continuing innovations that have become the cellular phone systems that we use today.

More than just history of telephone technology, this program examines a wide variety of contemporary aspects of telephone communication. There is an interesting chronology of mobile or portable phone designs as they have become increasing smaller in size, lighter in weight and equipped with more advanced features of larger memory, pictures, video, MP 3 players, and text messaging. ‘Re-Cellular’, one of the largest cell phone recycling facilities in the world is visited and the process by which cell phones are made ready to be used again is demonstrated.

Another interesting aspect of this program are the examples of how cellular networks have developed, with computer generated models showing how cell phone towers and cellular networks function. There is also a discussion of GPS, or Global Positioning Systems, and how GPS chips function when they are inside a cell phone.

Historical events surrounding the earliest forms of electromagnetic speech devices and the eventual patent by Alexander Graham Bell for the first telephone are also included. Some of the details surrounding this first patent, and the debate over what other inventors’ actually contributed to the development of the first telephone is examined. The eventual creation of American Telephone & Telegraph (or AT&T) and the advances that lead to the creation of a telephone network throughout the country and long distance phone calls in nicely presented. The development of coaxial phone lines, transatlantic telephone cables, fiber optics, and finally the creation in 1962 of AT&T’s first Telecommunications Star Satellite, is also included.

Alexander Graham Bell wanted people to answer the phone by saying “Hoy-Hoy.” Thomas Edison argued for the commonly used “Hello.” Edison won.
In the 11th century BC, the Greeks lit hilltop bonfires to send news. Now, just three satellites are enough to link any two places in the world at the speed of light.

Calling Cards and Misconceptions: Get the Truth

When it comes to using prepaid calling cards, there’s a lot of information out there. They’ve been around for a long time, and that means that there’s been plenty of time for people to form opinions and come up with some gross misconceptions about these handy communication accessories.

Misconception 1: Phone Cards Don’t Work on Mobile Devices

While this can vary from carrier to carrier, most phone cards work just fine on mobile devices. Since you’re calling a local number to input your PIN and then connect to an external network, the call generally counts as local on your phone’s end. This does mean that you’ll have to pay for the local minutes you do use on the call, but it’s definitely better than dealing with exorbitant roaming charges.

Misconception 2: Calling Cards Only Work in Their Country of Origin

International phone cards are a booming business, so this misconception is pretty far-fetched; these are designed to allow you to call a different country while only paying a minimal local call charge rather than an astronomical international call charge, so having them be usable only in one country wouldn’t be very useful. This misconception probably comes from the fact that some calling cards offer coverage only in a handful of countries—usually the United States, Canada, United Kingdom and Australia—thereby leading to a misunderstanding about their usability. However, these cards tend to be usable from either side of the pond, allowing two people in different countries to share the card and talk at their leisure. It’s usually a little cheaper to use a limited option card, but not always.

Misconception 3: Nobody Uses Phone Cards Anymore

While local phone cards may be less and less common as many mobile phone prices drop throughout the world, international calling cards are still the most economical way to keep in touch with friends, family and colleagues all over the globe. It’s common for businessmen traveling outside the country to use a calling card to contact their employers and loved ones back home, in order to keep down costs while away from home; it’s also popular for students studying abroad to have a calling card maintained by their parents, allowing them to call home whenever they want without running up a huge cell phone bill.

Phone cards are still a popular and functional option for keeping the cost of calling to a minimum. You may find that the truth of the matter opens up a plethora of options for keeping in touch—no matter where life takes you.
