• The exchange of information through language is an incredibly important achievement of humanity. By speaking to another person, we can convey our emotions, share knowledge, or ask for something to be done.

• Conversing via sound has enormous advantages, but unfortunately, there are also limitations. One such limitation is the inability to exchange information over long distances. If the other person is too far away, we won’t be able to communicate. It seems like a trivial fact, but someone once had to solve this problem.

• What to do to talk freely over large distances? The answer turned out to be telephones, which have been continuously improved over time and have taken on more sophisticated forms.

• In 1973, Martin Cooper from Motorola made the first mobile phone call using a truly portable device. This mobile device was not limited to functioning only in a car, as the small size of the entire apparatus allowed it to be carried around.

• 1G stands for "1st Generation," which refers to the first generation of mobile phone technology. The 1G network was analog, and mobile phones and related services were considered expensive. 2G, the second generation network, was digital and used the GSM (Global System for Mobile Communications) standard. This enabled text messages and provided limited access to the internet.

• When 3G emerged, smartphones began their dominance on the market, turning mobile phones into devices with much greater capabilities. The third generation provided widespread internet access, but the increasing popularity of smartphones required much greater data transmission capabilities, which is why 4G and the LTE (Long-Term Evolution) standard became necessary.

• The fifth generation marks a period of rapid development in concepts such as the Internet of Things, requiring even higher data transfer rates. 5G offers faster data download and upload speeds, better connection stability, and very low latency. Smartphones today are filled with sophisticated technology and offer a multitude of possibilities far beyond voice communication.

• It is amazing that mobile phones have evolved into smartphones with advanced operating systems and surprisingly wide-ranging capabilities. Voice transmission over distance is just a small part of what we can do now.

• Phones have been enriched with color displays, cameras, and suddenly everyone could take photos and record videos almost anytime, anywhere. They have become multimedia hubs for playing videos, listening to music, and even gaming.

• Their design has gone through various stages of evolution, but the true revolution occurred in 2007 when the first iPhone popularized phones with large, touchscreens and very few physical buttons. It was also significant when the App Store platform was launched.

• Today's smartphones are, in many ways, the opposite of the first mobile phones – they are small, light, incredibly efficient, and have surprisingly many applications. They have become an essential tool in the lives of many people, even though they were once a gadget for the wealthy.

Divide into 4 groups. Each group will prepare a presentation on the functions and applications, as well as the advantages and disadvantages of one smartphone model. During the presentation, one group member will take on the role of a salesperson in a mobile phone store, while the others will act as customers buying a modern smartphone (family). The salesperson's role will be to persuade and convince the customers to buy that particular model, demonstrating its functions, capabilities, advantages, and disadvantages. Try to approach the chosen roles with honesty, not hiding any flaws of the smartphone, but also emphasizing its strengths. Each group will present a different model of smartphone, so you will learn about the characteristics of several different smartphone models.

Why will you work in groups?

Because each group will be responsible for creating a presentation about a different phone model. Although modern smartphones share similar features, "the devil is in the details," and by uncovering these details, you will have the opportunity to learn the exact characteristics of several models. Before starting the task, draw lots with the teacher and select the smartphone models you will describe.

The first historically significant smartphone was created in 1992. It was a prototype device called Simon, which IBM introduced at the COMDEX trade show and launched on the market in 1993. In addition to the mobile phone function, it offered a calendar, address book, calculator, notepad, email, and games.
