                                                Evolution of Cellphones and Cellphone Subscribers

            The history of cell phones goes back to the early 1920’s. The first use of any type of phone or radio in a car was in taxis, trucks, or car with two-way radios.  As cell phones evolved over time, user subscribers grew tremendously in number and usage.   The first cell phone was used by Swedish police in 1946.  It was generally similar to a two way radio.  In 1947 an engineer from Bell Labs discovered cell phone towers which had capabilities to transmit signals in three directions.   The cell phone generation improved and became limitless as time went on.

            In 1971 AT&T submitted a request to the FCC for cellular service. It took about ten years before the request was granted.  Once granted cell phones worked only on analog frequencies.   In 1990 amps went digital and went online.  

            Motorola was the first company to come out with the first cell phone called Motorola DynaTac 800X.  The FCC finally approved this device after years of testing.  After about 15 years of development Motorola DynaTac was finally available to the public.  During this time 13 x 1.75 x 3.5 inches was considered to be lightweight and easy to carry.  These phones were shaped like tote bags and could completely cover the side of your face.   A cell phone’s main power source was the battery of the car. It was not common to have a cell phone in the early 80’s. Majority of people who had phones were doctors, lawyers, drug dealers or people who had money. The demand for cell phones would increase rapidly and the need for a phone would continue to grow.  

            During the 90’s technology for cell phones worked on 2 G or second generation.  Cell phones were operable on systems called CDMA, TDMA, and GSM. During this era the look of the cell phone changed.  Cell phones went from big and heavy devices to light weight and small. These 2G phones were faster and better because they worked on radio signals.  Eventually analog service became obsolete. The improvements made the demand for a cell phone expand rapidly.  The advancements paved the way for PDA devices. 

            Cell phones presently are 3G or third generation.  The wave of technology increased subscribers and usage.  More people will become dependent on cell phones for work, school and life. During this era cell phones will be able to text, sms, and send emails, steam video’s and use Wi-Fi over air waves. The use of sms and text messaging will become popular with teens and young adults.  Now it’s so common to see someone with a cell phone or PDA.   Charts show how subscribers have tripled since the 80’s.  Teenagers make up a large number of users presently. While 75% of teens own phones, 25% do not own cell phones and 54% of teens will text from their cell phone and check Facebook daily.   Adult subscriber’s text, email and Facebook, but most use their phones for more important use. 

            In conclusion evolution of the cell phone changed due to improvements in Technology.  The cell phone would become light weight and portable for daily use.  The cell phone improvements like text, sms, streaming videos, and Wi-Fi would increase subscribers among teens and young adults. The evolution made cell phones more user friendly and accessible for all.  Society would become dependent on cell phones for life.
