Laptops need to use the Internet when working on the move or in other environments without WiFi. Generally, we will use mobile phones to build hotspots to provide WiFi. However, there are two disadvantages to using mobile phone hotspots for a long time? The heating problem of mobile phones and battery life Problems, portable WiFi can solve these problems. The following is about the experience of Feimao Zhilian U8 portable WiFi, which can be used as a reference.

Overall configuration and appearance

From the packaging point of view, the packaging of Flycat Zhilian U8 Portable WiFi is relatively simple. On the front of the box is Flycat’s big logo? FLYMODEM. The packaging box The whole body is made of blue, and the product model and IMEI code and other related information are printed on the back.

Unpacking, it mainly consists of Feimao Zhilian U8 portable WiFi, Type-C to USB-A adapter and quick guide.

Looking at the appearance details, Feimao Zhilian U8 Portable WiFi is small and light. The thickness of 9.4mm is about the same as a mobile phone, and the weight is as light as 25g, which is close to a USB flash drive. You don’t have to worry about adding weight to your luggage when you go out.

The surface of Feimao U8 Portable WiFi adopts a metallic frosted style, with a silver dividing line on the front and Feimao Zhilian’s logo on the bottom.

The interface part uses the mainstream Type-C, which can adapt to more than 98% of mainstream models and mid-range networking devices. In addition, the Type-C interface can be used to achieve first-line connection, plug and play, direct connection to the Internet, the network speed is increased by more than 40%, and up to 8 devices can be connected at the same time, supporting uplink and downlink rates of 50Mbps/150Mbps.

In addition, Feimao U8 adopts a battery-less design, which requires reverse power supply from the device before it can be used. When there is power, there is high-speed network, so after opening the back cover, you can only see the SIM card slot inside. Feimao Zhilian U8 portable WiFi currently supports 4G full network. The equipped Feimao clone card can achieve one card and three networks, and can switch to the best network in 12 seconds. In terms of SIM card specifications, it only supports mini-SIM cards. After installing the SIM card When using it, the SIM card chip must be facing down and the notch facing out before it can be used.

When the SIM cards are placed correspondingly, and then the Type-C interface is connected to a device that supports OTG reverse power supply, Feimao Zhilian U8 will automatically turn on. At this time, if the SIM has completed activation and other steps , the device will automatically search for signals to connect.

Network speed test results

Whether the speed is fast is one of the important factors to test the performance of portable WiFi. The following is a simple test using a third-party speed test APP, indoors, outdoors and on the subway. Wait for the underground environment to be tested.

The data measured outdoors is slightly better than indoors, reaching 57Mbps. This speed is definitely sufficient for daily short video browsing and app downloading. However, the subway has a little interference with the signal due to the underground environment. , its test network speed is the slowest among the three scenarios, but it is only 40Mbps, about 5MB/s, and the uplink speed is also 21Mbps. It is easy to listen to music online and catch up on dramas when commuting to and from work.

The signal is also another important factor in testing the performance of a portable WiFi. Thanks to the built-in three high-gain 3D three-dimensional LDS antennas of Feimao Zhilian U8, the 4G network is more stable. The distance from the portable WiFi will also affect the network speed. We also tested the network speed performance of this portable WiFi at different distances when connected to WiFi, respectively at the distance of 1 meter, 10 meters and blocked by a wall. Perform testing.

The actual measured WiFi distance is 1 meter and 10 meters, and the network speed basically does not change much. The uplink rate is stable at 26-27Mbps, and the downlink rate is slightly reduced, but it is still sufficient for daily use. In addition, we also tested the wall penetration capability. When separated by a wall, the delay and jitter did not increase significantly. The downlink rate is still 44Mbps, and the stability is good.

We also measured the WiFi signal strength at a distance of 1 meter, 10 meters and a wall. The signal strengths of the three are all within -70dBm, which is a good range. The number of dBm The smaller the value, the better the signal.

It must be noted that due to differences in test environments and operator networks, the above data only represent the results of the scenario at that time. To be precise, this kind of data performance is consistent with most usage scenarios of the vast majority of users.

Real usage environment simulation

After reading the above theoretical performance test, you might as well take a look at the performance of Feimao Zhilian U8 portable WiFi in actual scenarios. We will simulate users’ daily usage scenarios. , respectively conduct game delay tests, live streaming and short video viewing to see whether this portable WiFi can meet the needs in different scenarios.

When using Feimao Zhilian U8 portable WiFi to directly connect to the iPad, we used Genshin Impact for testing. Compared with the local connection to WiFi, in the direct connection state, the latency of Genshin Impact is only 74ms, and the operation is smooth. Even in large-scale battles, there is no lag. After all, a one-second delay is the treatment of being shot in the head in a chicken-fighting game.

Browsing short videos and watching videos online are now the norm for most people. Internet speed lags often affect the user experience. After being directly connected to Feimao U8 portable WiFi, we can actually watch live broadcasts smoothly, even if Playing online videos is no problem, 4K? 60 frame videos are smooth and silky when you drag them.

Finally, we also used a third-party speed test app to conduct theoretical tests on games, videos, and video calls. In actual tests, whether it was playing games or video chatting, Feimao Zhilian FM-U8 portable WiFi experienced excellent network speed and signal coverage. The experience in terms of transmission delay and transmission delay is both good.

System setting experience

Using Feimao Zhilian U8 portable WiFi is also very simple. First, connect the Feimao clone card to the U8 portable WiFi and use the Type-C interface to connect to the electronic device. After installing the device, you can directly connect to the Internet by turning off the WiFi of the device itself. However, some devices cannot be used if they do not have the OTG reverse power supply function.

Before you start using it, you need to install the "Flying Cat Butler" App, complete the binding of the data card and the device, etc. Once everything is ready, you can start surfing at high speed.

If the direct connection to the Internet function cannot be used on some devices, you can disassemble the back cover of the fuselage. There is an initial account and password on the label, and you can connect to the Internet. In addition, the "Flying Cat Butler" App also has many practical functions, including checking data usage, controlling device restarts, and changing WiFi passwords.
