Hello everyone, I am a big national treasure I brought a business artifact to everyone today. This thing is called a mobile stick. Now the name is very direct, um, this stick, that great one. Let me first summarize the role of this small thing: 1. Turn the wired broadband to WIFI; 2. Transfer the USB 3G network card to WIFI; 3. Transfer the ADSL dial-up to WIFI; 4. USB as the power supply source, light in weight and small in size to prepare From time to time. First, the appearance. Second, the basic operation. Charging treasure, mobile phone charger, laptop USB port, etc. can all be used as a power source. After the power is turned on, the blue light flashes, indicating that the startup was successful. The wireless network with the hotspot name dostyle_WR201_XXX is searched. After entering the password, it is connected. After connecting, you can follow the steps to set up the router. You can set up an ADSL dial-up account, set up dynamic IP, static IP, etc., insert the wired broadband in the hotel, and simply set it to use. This article will not repeat them. The following plans to focus on signal strength, network speed, and the use of 3G network card to WIFI evaluation. Third, the signal test. Method: There is a Dafa Z3 on hand to test signal strength and download speed for different distances and obstructions. Basic comparative tests, not professional quantitative tests, do not spray The first is a distance of 0.1 meters, without obstructions. At this time, the intensity is -41dbm, and the download speed is 557KB/s, which is acceptable, but it does not reach the peak value. Contrast next to the red curve is telecommunication cat WIFI wearing a wall, the signal is slightly poor, but the download speed reached 1M/S or more, after all, relatively large, certainly strong ah. (My home is 10M fiber optic bandwidth) Look at the speed in the upper left corner: Look at the speed in the upper left corner: At a distance of 3 meters, a wall is blocked, the signal is attenuated to -75DBM, and the download speed is reduced to 200-300KB/s. It is still acceptable. The signal of the telecommunication cat in the red curve is strengthened. Why do you think I just said? Did the light cat wear a wall? It is now closer to this cat and it does not have a wall. It can be seen that wall penetration affects both the signal and the speed of the moving stick. At a distance of 5 meters, two walls are blocked, and the signal is further attenuated. Above -80DBM, or even higher. At this time, although there is a signal connection, it is no longer possible to access the Internet, and soon it is disconnected. The red curve next to it is a comparison of telecommunications. Light cat, for him also wears a wall, so the signal is also attenuated. As a result of the test, two walls were defeated. Fourth, 3G Internet card to WIFI. There is no modem inside the stick, so you can't directly insert the SIM card. You need to insert the 3G network card on the stick. Theoretically, it supports the mobile, telecommunication, and Unicom standard internet cards. I tested the use of the Internet card produced by Chrysanthemum. Perfect support, mainstream internet cards should all support. After the fit is like this After the card is plugged in, the red light flashes first, then the blue-violet light flashes, then the blue light flashes, and the last blue light turns on, indicating that the automatic dialing was successful and the 3G network has been connected. This speed depends on where you are, the signal, and so on. The network card that I use here is HSDPA standard, namely the highest peak is 14Mbps. Look at the upper left corner about 200-400KB / s or so, you have reached the peak. The advantages and disadvantages are summed up: advantages, the emphasis is on compact and convenient, all kinds of functions have; disadvantages, general performance, does not support 4G network card. what? You say no use? All tell you that it's a small stick, a little stick, and if you want to have a strong function, you can look at the amount of moving sticks or sticks.
