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.

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
