When the operators went home, we would have to meet people in person. A telephone should be used wisely and gave the most highest respect.

Although things have changed throughout the years. We have invented things that no one has ever thought about. The one invention that could change the world would be the cell phone. If we didn't have cell phones what would we do?

The first invention of the cellphone that eventually led to the modern day smartphone was created in 1973. The first cellphone prototype was called the Motorola DynaTAC in 1973. The first cellphone call ever made was from Marty Cooper, who was an employee of Motorola employee at the time. The world’s first smartphone was released by its’ creators, BellSouth and IBM in 1993. Its’ features included mail, fax, address book, calendar,

Energy travels in waves. The distance from one wave to the next is the wavelength. Frequency is the amount of times the wave oscillates up and down per second. The higher the frequency, the more energy. Frequency is measured in Hertz. One Hz is one wavelength per second. Different electronical things are operated at different rates of hertz. At this point, the fastest connection runs at a 2.1 GHz (gigahertz) range-- that’s 2.1 billion wavelengths per second. Cell phones use low radiation called radio frequency (RF). A cell phone sends and receives
