Almost there!

Dupyo and I are just pretty much putting the last finishing touches on this project. We have the poster made, and we made a radio tower and cell phone tower with some pictures and water bottles. We will have our citations on Thursday and be ready to present. We will be presenting how information is sent to cell phone to cell phone, and how that relates to how information is sent from a radio station to a radio tower, to say a car's antanna.

Almost there!

Our project is coming along well. We have decided that we don't really need a power point so we are just going to make the poster and physical diagram of a radio/ cell phone tower. And describe how information is sent to and fro from cell phone to cell phone, and also how it affects the users.

Project coming along

Our project is coming along fairly well. We have started the PP and are almost complete with that. Today after school I am going to buy a poster board, and tomorrow after school we will finish PP and start the poster.

We are going to start our poster board and power point starting this week, and we will be finished by next week.

For our presentation on cell phone frequencies and waves will consist of a poster board, and possibly a video or an app that allows you to play with frequencies and see them on a phone. Then me and Dupyo will text each describing what is happening to the text as is being sent to the other phone.

Effects on Users

People who use are exposed to all of the radio frequency that they create. Large ammount of RF can cause body body tissue to heat up, and to overheat connected tissues. This is counteracted by the body naturally, since blood will absorb heat and transfer it away from tissue. Regardless, the RF generated by a cell phone isn't enough to cause tissue to heat anyway since the energy is so relatively small.

The frequency in cellphones.

The term for radio waves, and at what power they're at, is calling radio frequency energy. Cell phones don't have a great deal of radio frequency energy, or radio frequency. Generally speaking a cell phone has a radio frequency energy of somewhere between 850 and 1900 Megahertz. Put in practical terms, that is somewhere between a portable radio and a microwave oven. All in all, a cellular phone is a relatively weak device. However, there is still a question as to whether or not the waves it produces have more of an effect that people think

Why does cell phone waves damage your body tissue?

We are yet to find out why these significant cell phone waves damage your body tissue. But do not worry you have to excessively use the cell phone and have it constantly up on your ear. Not just talking on the phone but doing other stuff. Such as texting while talking, surfing the internet, or listening to something like pandora that requires some more wave frequencies.

Cell Phone

Cell phones are an extremely common tool in today's technologically advanced world. Cheap, portable, and effective, these small phones are considered by some to be a necessity. However, a cellular phone is not actually a real phone in the true sense. A cell phone is in fact a radio transmitter and receiver. When a person speaks into a cell phone, the machine translates their speech into radio waves. These waves are relayed through cell phone towers and delivered to another phone. Similarly, when a cell phone receives a call, it transfers the radio frequency back into speech. This is the reason that being underground, or in concrete building, can make cell phone reception difficult.

Cell phones

Today we leaned that cell phones signals are from transceiver known as a cell station or base station. When joined together these cells provide radio coverage over a wide geographic nation.
