We thought that it would be important to talk about the creation of the internet. Without the internet there would be no VoIP technology and the face of telecommunications would be a lot different then what we know today. Before the internet there was the ARPANET or the Advanced Research Projects Agency Network. ARPANET was… Continue reading The Early Internet
Modern VoIP
VoIP continued to grow and by 2003 the number of VoIP calls was 25% of all voice calls. The implementation of broadband Ethernet service mad call quality improve significantly and made connectivity much less of a problem. Broadband Ethernet was a huge improvement and is probably the reason for the rise in VoIP voice calls. … Continue reading Modern VoIP
Early VoIP
This installment of the historyoftelephony will be about VoIP or Voice Over Internet Protocol. Most phone systems that businesses or small business use is a VoIP system. VoIP is the transmission of voice “data packets” from one IP address to another over the internet. This was originally invented so people would not have to pay… Continue reading Early VoIP
The Modern Mobile Phone
Before 1973 most mobile phone telephony was limited to phones installed in cars or other vehicles(See Amos Joel patent 3,663,762.) like a tractor or a train. Martin Cooper who was a researcher and executive for Motorola, helped create the first handheld mobile phone. On April 3, 1973 Martin made the first mobile phone call… Continue reading The Modern Mobile Phone

The Bell Telephone
By the year 1904 there were over three million phones in the US that were connected by manual switchboard exchanges. From 1878 when the telephone exchange was invented to 1904 there were three million phones. In a 26 year span 3 million phones were added to people’s houses, businesses and community centers. That is over… Continue reading The Bell Telephone
The Early Telephone
Without the technological advances of the mechanical acoustic devices and the electrical telegraph the modern day telephone as we know it might not be around today. The inventor of the telephone is not entirely clear. Charles Bourseul, Innocenzo Manzetti, Antonio Meucci, Johann Philip Reis, Alexander Graham Bell and Elisha Gray all have been credited with… Continue reading The Early Telephone
Telecom Terms
We thought it might be helpful to have a glossary of telecom terms just in case people did not know what they were. If you can think of other terms that should be in here or you want in here please let us know. Access point- A radio access point (wireless data base station)… Continue reading Telecom Terms
Electrical Telegraph
The next big innovation in the history of telephony that we are going to talk about is the electrical telegraph. The first working telegraph was produced by Francis Ronalds, an English Inventor in 1816. At his home he set up a completely underground system in a 175 yard trench he built. The lines were connected… Continue reading Electrical Telegraph
Mechanical Acoustic Telephones
We thought we would start out by talking about the “tin can telephone”, or “lovers phone”. Before the invention of the electromagnetic telephone or telegraph there were mechanical acoustic devices to transmit sound to distances further than normal speech. These devices would transmit sounds through pipes, wires or string. One of the earliest known experiments… Continue reading Mechanical Acoustic Telephones
