For the author, the Internet has become one of the indispensable projects like eating and drinking. Once the Internet is disconnected, inexplicable impatience often appears, and it always feels like something is missing. For young people who like tossing and turning, the network has become an indispensable and important function in modern life. When you get used to the Internet, one day you suddenly find that you can't access the Internet. You will feel that your life has lost some important aspects. Whether you use the Internet to chat about QQ, or use the Internet to send microblogs, or stick to reading all kinds of news every day, in any case, the Internet has become the most important and indispensable function of modern people, For most mobile phone parties or Pad parties, the wireless Wifi network obviously occupies a larger position. The author has personally experienced that some high-altitude areas of Qinghai Tibet Plateau do not even have a signal from China Mobile. It is difficult to realize the call function of wireless Internet, that is, to use the telephone normally. However, in these remote areas with high altitude, WCDMA network coverage is available. In these areas, The advantages of universal WCDMA are far stronger than those of mobile and telecom companies. Today, the product that I was lucky to get for testing is a smart product that converts WCDMA 3G network signals into wifi and shares it with everyone. Its name is 747 box S1 upgrade.

Like most electronic products, the upgraded version of the 747 box S1 also uses environmentally friendly pulp packaging, with blue wrapping paper wrapped outside to display some basic information of the 747 box S1.

The basic technical parameters and product specifications of the 747 box S1 are marked on the outside of the blue package on the back of the box. It can be clearly seen that the box supports WCDMA, and the manufacturer is Beijing Heimi Century Network Technology Co., Ltd. The box is a combination of Wifi and mobile power supply. The configuration of the main and auxiliary antennas allows you to stay on the high-speed railway without disconnection. The Wifi speed at a certain speed will be tested later. The box capacity is 5200mAh, the mobile mode used is WCDMA, and it has the NFC Internet access function. The charging input is 5V/1A and the output is 5V/2A, which can meet the charging requirements of most mobile phones and tablets. In a good network environment, it can be used for about 12 hours.

Open the package, you can see the internal structure of the 747 box, the box body, the data line and the instructions of the box.

All accessories are 747 box S1 upgraded host, MicroUSB data cable for charging, quick use guide and manual.

The SIM card attached to the box is placed inside the red simple instructions, and the 3.5G traffic promised by the box and the 2000 minute network phone are included.

The front of the 747 box is the battery power indicator, wifi signal indicator and NFC indicator, and the bottom of the middle of the box is the logo of the 747. The NFC indicator shows that the 747 supports the function of NFC touch to access the Internet, which adds a simple option for customers to access the Internet.

The back of the upgraded version S1 of the 747 box provides some basic sending parameters, such as charging input parameters, charging output related parameters, and battery capacity.

On the side of the 747 box is the relevant interface and description. It can be seen that the 747 box has a default wifi name and wifi password when it leaves the factory. From the password and name, the factory default account password of each machine in the 747 box is randomly generated, which makes it easy for users to use without changing the default account password, MicroUSB is used to charge the 747. The USB output port can be used as a charging bank to meet the charging of mobile phones and tablets. The reset button of the box can realize the reset function when you forget the password you set, which is convenient for users.

The SIM card slot and switch button of the box are designed on the side. Press and hold the switch once to realize charging output. Press and hold the switch button for more than three seconds to automatically turn on wifi and realize the WCDMA to Wifi function. The SIM card slot can be opened easily. The SIM card slot adopts a pop-up design to facilitate the user to put in or take out the SIM card.

The three icons on the front represent the meaning. Under strong light, the blue light is slightly dim, but when the wifi is powered on, it is red light, and the color is relatively easy to identify. After the connection is successful, the wifi icon will also change to blue.

The 747 box provides Android version and iOS version applications. There is no problem with the iOS version I have, but after the installation of the Android version (cloud OS3.0.2), there is a flash back when I open it. The first time you use the 747 box, you need to register. It is recommended to use your own mobile phone number to register, so that you can use the Internet phone later. After the registration is completed, when the box is not connected, you cannot obtain relevant information. You can complete the registration by scanning the barcode on the mobile phone card, so the mobile phone card is still very useful. Don't litter it.

After the connection is completed, you can query the 3.5G traffic of the 747 box. The settings of the box are relatively simple. You can modify the SSID and its password. The connected devices display the devices currently being connected, and you can choose to add the devices to the blacklist.

The 747 box provides convenient recharge and purchase functions, which can complete the flow recharge of the box through flow recharge, The price of the 3.5G national 180 day traffic package of 159 yuan is moderate, not too cheap, but not too expensive. The key is that the package function provided by the card will be activated after the previous level of 3.5G traffic is used up, so don't worry about shortening the use time due to early recharge. The 747 box store provides a convenient connection to purchase 747 in the app. At present, only this product is sold, but the color is different.

The side navigation of the 747 is also very simple. You can change the nickname and gender. These two functions don't really matter. Only the mobile phone number in the account can be used for displaying the network phone.

The 747 box network phone function can only be used when the 747 box is connected, and the dial provided with the 747App must be used. After several tests, the author found that the 747 has serial numbers, that is, sometimes registered phone numbers can be displayed normally, but many times unknown phone numbers are displayed, It is easy to be mistaken for harassing calls and added to the blacklist, but this is also a common problem of the current network phone. However, in the case of a good network, the actual voice quality of the call is still good. However, the recharge function of internet phone is not yet available.

To test the speed of the 747 box, we use a popular speed measurement software, SPEEDTEST， The author tested the home network speed. At present, the 10M China Mobile optical broadband is used, and the measured speed is basically the same as the broadband speed. From the 2G/3G display on the author's mobile phone, we can see that the 3G signal moved by the author's location is basically not connected and has automatically switched to the 2G signal, but the author cannot intuitively test the speed of WCDMA. Therefore, the 747 box is connected and the speed of WCDMA to wifi is tested. The measured effect is not good, and the download speed is only 0.78Mbps.

The author tested the network speed of the 747 box in four locations and five situations, namely, the urban rural junction without China Mobile 3G signal, the factory office area in the city, the 60 mile car The 80 mile car and coal mine locomotive power supply charging room (the place where the coal mine signal is weakest is generally located in the miner's lamp charging room. This time, due to the work and schedule, the miner's lamp charging room could not be accessed for testing, which is a pity in this evaluation). The following is the test situation:

In the box above the picture on the left is the network speed of the factory office area in the city, which can basically be stabilized at about 2.5 Mbps; In the middle box of the left picture is the network speed of the urban rural junction without China Mobile 3G signal. From the measured results, the network speed is not ideal, and has not exceeded 1Mbps; The box at the top of the middle picture shows the test of a car speed of 60 miles. The overall network speed is relatively stable, more than 2 Mbps. However, when passing through the urban and rural fringe in the middle, the network speed test found that there was less than 0.5 Mbps; The lower box on the right side shows the measured data of the 80 mile car. Except for the 0.2Mbps measured in the case of a poor signal, the rest can be relatively stable at more than 2.5Mbps, indicating that the 747 box can still provide a relatively stable network speed on high-speed cars; The coal mine locomotive power charging room is located in a remote location, and the measured network speed is the best one. First, it shows the stability of the 747 box, and it also shows that China Unicom is very powerful in WCDMA layout.

Summary:

After more than a week of actual use, it is found that the overall operation of the upgraded version of the 747 box S1 is relatively stable, which can basically meet users' needs for the network; The power bank function of the 747 box can provide twice charging requirements for the iPhone 4S, but individuals do not recommend using the 747 as a power bank. After all, students who often travel on business usually have more than one power bank on hand, and the capacity of the 747 box is still used for the functions of the box itself as much as possible. In the process of use, it is found that the 747 box's shell still has some heat, but it is still within the acceptable range. Therefore, it is recommended to choose a well ventilated location when using the 747 box. The 747 has very perfect 3G support for WCDMA, and it can be more convenient to use the online network to realize the function of accessing the Internet at any time and anywhere, At the same time, the opening of the 747 box is also very high, and the use of the SIM card is not locked, so you can easily replace your own large flow card.

Through the use of 747 boxes for one week, the suggestions for 747 boxes are as follows:

1. At present, China Unicom Mobile 4G has obtained licenses. I hope that the 747 box can consider adding the function of 4G to wifi. After all, 4G is different from 3G in network speed;

2. At present, the USB output port of the 747 box is only used to realize the function of the power bank. It is recommended to add the function of the USB data interface, which can easily insert the USB network card, so that the USB network card in the hands of consumers can continue to play a role, and can also expand the use of other mobile operators on the basis of WCDMA;

3. Since there is obviously no advantage for individuals to negotiate with mobile operators, it is hoped that 747 boxes can negotiate with operators on high traffic packages with higher cost performance. For 180 days of use, 3.5G traffic is slightly insufficient;

4. The network phone often displays other mobile numbers. If feasible, it is recommended to focus on development so that the network phone can normally display the user's own number to avoid the embarrassment of entering the blacklist.

In a word, as a travel tool, the upgraded version of 747 box S1 is very powerful, and can basically meet the needs of frequent travel or travel or travel friends.
