HISTORY OF CELLULAR PHONES

Cellular is a type of wireless communication that is most familiar to mobile phones users. It`s called ‘cellular (1) __ to divide a service area into multiple ‘cells’. Cellular calls are transferred from base station to (2) __ from cell to cell.

The basic concept of cellular phones began in 1947, (3)__ and realized that by using small cells (range of service area) with frequency reuse they could increase the traffic capacity of mobile phones substantially. However at that time, the technology to do so was nonexistent.

Anything to do with broadcasting and sending a radio or television message out over the airwaves comes under Federal Communications Commission (FCC) regulation. A cell phone is (4) __. In 1947, AT&T proposed that the FCC allocate a large number of radio-spectrum frequencies so that widespread mobile telephone service would become feasible and AT&T would have a incentive to research the new technology. We can partially blame the FCC for the gap between the initial concept of cellular service and its availability to the public. The FCC decided to limit the amount of frequencies available in 1947, the limits made (5) __ possible simultaneously in the same service area — not a market incentive for research.

The FCC reconsidered its position in 1968, stating “if the technology to build a better mobile service works, we will increase the frequencies allocation, freeing the airwaves for more mobile phones”. AT&T and Bell Labs proposed a cellular system to the FCC of (6) __ , each covering a ‘cell’ a few miles in radius and collectively covering a larger area. Each tower would use only a few of the total frequencies allocated to the system. As the phones traveled across the area, calls would be passed from tower to tower.

A when researches looked at crude mobile (car) phones

B only twenty-three phone conversations

C base station as a user travels

D many small, low-powered, broadcast towers

E because the system uses many base stations

F a local station travelling

G a type of two-way radio

Key: 1 E; 2C; 3A; 4G; 5B; 6D.

3. Speaking and writing

A class survey

1) How many messages do you send per day?

2) What do you use your mobile phone for mainly?

a) Make phone calls

b) Send text messages

c) Connect to the Internet

Choose questions from above or write 4 of your own survey questions below. Then talk to 5 students and write their responses.

Write a short report after you have talked to five people.

For example: Most students send about 5 text messeges per day. Some students said they love Facebook and use it everyday. Afew students said Facebook is a waste of time. One student said…
