The Advantages of Using Wi-Fi on Your Smartphone

Wi-Fi is a method for devices such as smartphones to connect wirelessly to the Internet using radio waves. Connecting to the Internet using Wi-Fi requires a hotspot, but it is always faster than the 3G cellular networks which smartphones can also use to connect, and occasionally faster than 4G. Using Wi-Fi when it is available can also prove to be cheaper and make your phone run more efficiently in the long run than relying on cellular networks.

When you use a Wi-Fi network to access the Internet from your phone, the data usage does not count against your bundled data. Mobile providers often allocate a certain amount of data for free each month and charge you a fee for any data usage beyond this. By connecting via Wi-Fi wherever it is available, you can save your bundled data for situations when you might not be close to any Wi-Fi hotspots.

In many situations, your speed using a strong, dedicated Wi-Fi connection is faster than that of using your mobile network. It is very noticeable when transferring larger files. If you need to download large files or stream media to your smartphone in a hurry, it is much better to do so via Wi-Fi.

Battery life is extremely important for smartphones because you will not be able to connect to the Internet or use certain functions such as the camera flash if your battery is too low. Using Wi-Fi to connect to the Internet drains less battery life than using a mobile network, especially in situations where the cellular coverage fluctuates. Since Wi-Fi is generally faster than using mobile networks, you will also not spend as much time transferring the data, which further decreases battery usage.

     Wi-Fi là phương pháp cho các thiết bị như điện thoại thông minh kết nối không dây với Internet bằng sóng vô tuyến. Kết nối với Internet bằng Wi-Fi yêu cầu một điểm phát sóng, nhưng nó luôn nhanh hơn các mạng di động 3G mà điện thoại thông minh cũng có thể sử dụng để kết nối và đôi khi nhanh hơn 4G. Sử dụng Wi-Fi khi nó có sẵn cũng có thể chứng minh là rẻ hơn và làm cho điện thoại của bạn chạy hiệu quả hơn trong thời gian dài hơn là dựa vào mạng di động.

    Khi bạn sử dụng mạng Wi-Fi để truy cập Internet từ điện thoại của bạn, việc sử dụng dữ liệu sẽ không được tính vào dữ liệu được nhóm của bạn. Các nhà cung cấp dịch vụ di động thường phân bổ một lượng dữ liệu nhất định miễn phí mỗi tháng và tính phí cho bất kỳ việc sử dụng dữ liệu nào vượt quá mức này. Bằng cách kết nối qua Wi-Fi ở bất kỳ nơi nào có sẵn, bạn có thể lưu dữ liệu đi kèm của mình cho các tình huống khi bạn có thể không ở gần bất kỳ điểm phát sóng Wi-Fi nào.

     Trong nhiều trường hợp, tốc độ của bạn sử dụng kết nối Wi-Fi mạnh mẽ, chuyên dụng sẽ nhanh hơn tốc độ sử dụng mạng di động của bạn. Nó là rất đáng chú ý khi chuyển các tập tin lớn hơn. Nếu bạn cần tải xuống các tệp lớn hoặc truyền trực tuyến nội dung đa phương tiện cho điện thoại thông minh của mình, tốt hơn hết là bạn nên thực hiện điều đó qua Wi-Fi.

     Tuổi thọ pin rất quan trọng đối với điện thoại thông minh vì bạn sẽ không thể kết nối với Internet hoặc sử dụng một số chức năng nhất định như đèn flash của máy ảnh nếu pin quá yếu. Việc sử dụng Wi-Fi để kết nối với Internet sẽ tiết kiệm ít thời gian sử dụng pin hơn so với sử dụng mạng di động, đặc biệt là trong các tình huống mà phạm vi phủ sóng di động dao động. Vì Wi-Fi thường nhanh hơn so với sử dụng mạng di động, bạn cũng sẽ không mất nhiều thời gian chuyển dữ liệu, điều này sẽ làm giảm mức sử dụng pin hơn nữa.

Read the passage and choose the best answer.

When the era of digital technology has bloomed all over the world, human beings have witnessed thousands of wonderful inventions which can be applied in a variety of fields. Among those, robots are considered as a brilliant human creativity and have been developed further to serve people. Shaped into human bodies, robots are machines built to do tasks. Normally, they can be controlled by built-in computers so that they can do a series of automatic actions. These human-like machines help us explore new places, and uncover the mystery of the deep and cold ocean which is very dangerous for a normal body. They seem to play an unlimited role not only in exploration, but in medical fields as well. In hospitals, they can do a wide range of jobs in cooperation with doctors to improve the health care system. For instance, robots can assist physicians remotely to check on patients and even inspect them. They can search around hospitals to collect information about the sick and transmit it to the doctors through a screen to help them interact efficiently. With cutting-edge technology they can even do an operation with a high level of accuracy under professionals’ control. Thanks to robotic assistants, medical workers can save time and save many lives from fatal diseases. It is believed that the number of robots applied in the medical industry will be expected to increase dramatically over the next few years.
