Cell phone history and cell phone antennas page two.

We'll cover more cell phone history here right up through the 1960's. This was an era of many changes in technology and the impact it had on our society and around the globe! Most interesting I think was the Motorola MTS mobile phone! This truly was the first mobile phone even though it required a motor vehicle and a lot of power to operate!

This next cell phone is an example of my first bag phone.

You will encounter more static the farther out you get, but you can hold a connection! Digital service works better than analog in urban areas because of the amount of cell phone traffic on the airwaves, but digital cell phone signals will not travel as far as analog signals will.

Now do you see how important it is to choose the right antenna and cell phone amplifier combination?

This goes double for digital and analog phones!

This next phone was made for military service. It's kind of ironic how Hedy Lamar's idea and knowledge had helped the war effort and yet here is another example! This army field phone would not have been possible without her.

An example of a cell phone made for the battlefield!

So you think we should take the phone with us while we go shopping?

This 1964 Motorola MTS cell phone started the evolution of the car phone!

Cell phone history radically changed with the introduction of this mobile phone! Even though this cell phone was full of tubes and was also analog, calls on it were more clear and static free and stable than at any other time of the cell phone before this.

Although the first idea of the cell phone was back in 1947, the technology just didn't exist yet. This was a version of the "Secret Communications System" designed by Hedy Lamar in 1942. The theory was that users could be on the phone while in a moving vehicle and your calls would be handed off from tower to tower all along your route. That's right! Hollywood actress Hedy Lamarr saw her first real invention put to good use making cell phone history with this phone!!

You simply had an account with your account number given to the operator and your mobile would be manually connected to a land line phone with operator assistance! While this was a remarkable feat for it's time, it had a big drawback. Since these were analog two way radio signals, anyone could listen to them and use your account number for their own calls!

You also had no reasonable expectation of privacy and had to be careful not to divuldge personal information while on this cell phone. We have the technology now to be able to make our cell phone conversations private, but we still roam around talking while traveling in the same manner.

This is still how cell phone calls are handled today!

The mobile phone equipment of the time was a variety of radio electron tubes and the power needed to operate them was considerable.

Automobiles back then had generators instead of alternators and their power was limited to about 50 amps of current. When alternators came out, we had the ability to produce 75 amps of current in a much more compact size. Now we could even put multiple alternators in a car or other vehicle to power accessories like mobile phones!

This was the first cell phone made to be vehicle mounted and it was made by Motorola back in 1964! It was called the MTS and you turned it on and waited for it to warm up because it still had radio tubes inside! Then you turned a crank and found an available frequency not in use and placed your call with a mobile operator!

Can you imagine what it would have been like for Hedy Lamar to actually make cell phone history with her own invention by placing a call on this phone? Since there were only a few frequencies available it presented some obvious problems. How would you charge for these calls? Remember that you turned a crank to get to an operator and placed a call then?

You could hear others having a conversation to know that the line was in use, and if you used billing information to give to the operator others could hear it and use it too! Can you imagine getting this cell phone bill? This was a problem and more than one user found unauthorised calls in their bill. Mobile phone companies realised the only way to straighten this out would be for the number being called had to pay for the mobile call, but the recipient had to agree to this.

This was the reason that most early mobile phone users were businesses because they could absorb this cost as a necessary cost of doing business.

Privacy? What Privacy?

Since you were on a two way radio, you could not expect a reasonable assertion of privacy on the early networks. It was thought that users could be assigned one frequency apiece, but with so many users wanting mobile phones, there just weren't enough frequencies to go around! Cell phone history was in trouble unless more frequencies could be put into use. Fortunately Hedy Lamar would see her invention expand into more uses with the introduction of transistors in the 1960's!

I seem to have found a renewed interest in old films of this era! Hedy Lamar was also a great actress and her talents were many.
