Today, the integration and application of satellite communication technology in mobile phones have made significant progress. It can provide connections with the outside world in remote areas such as oceans, deserts, forests, or so-called “information wastelands” without traditional signal coverage. means.
This is a valuable communications resource for those exploring, working, or living in these areas.
However, until now, mobile phones equipped with satellite communication functions have a common limitation: users can only make voice calls hands-free. This limitation has reduced the practicality and convenience of satellite phones to a certain extent.
In this regard, OPPO’s innovation is particularly important.
At present, OPPO has applied for a total of 26 patents related to satellite antennas. As OPPO’s first satellite communication mobile phone, OPPO Find and hands-free dual-mode two-way satellite calling.
The addition of the handset mode not only improves the user’s flexibility in satellite communications in emergencies but also significantly improves the convenience of daily use of satellite phones.

Communication capability test
OPPO Find X7 Ultra Satellite Communication Edition is OPPO’s first satellite communication mobile phone and the first device to support 5.5G mobile communications.
5.5G, also known as 5G-Advanced, is an advanced version of 5G technology and is regarded as the transition technology between 5G and 6G.
The ultimate speed of the 5.5G network of the OPPO Find X7 Ultra satellite communication version is up to 300% higher than that of the 5G network, taking the lead in leading mobile phones into the 10G mobile era.
In terms of satellite communication capabilities, Find The exclusive multi-satellite antenna pattern control technology allows the mobile phone to adjust the satellite pattern during satellite communication so that the antenna beam can accurately point to the satellite.
This upgrades the mobile phone satellite call experience from the traditional “satellite intercom mode” to a “satellite phone mode” that is more in line with user intuition. This innovative technological improvement allows users to enjoy a more efficient way of communicating even in extreme environments.
In other words, through the optimized antenna design, users can easily make satellite calls in their ears as naturally as using a regular mobile phone. This greatly improves communication reliability and convenience in challenging environments.
In this regard, we also conducted a series of tests on the satellite communication capabilities of the OPPO Find X7 Ultra satellite communication version.
Compared with the ordinary version, the OPPO Find X7 Ultra satellite communication version has an additional “Satellite Network” option in the settings interface, and you can use the satellite communication function by clicking on it.
When using satellite communication, you must first find an open space with no obstruction in front of you, follow the actions shown in the diagram, and use the GPS and gyroscope of your mobile phone to perform a figure-eight shake for calibration. Then, start searching for satellite signals.
To ensure signal reception, once you find the general direction of a nearby available communication satellite, follow the page prompts and gently turn your phone to ensure it is aligned with the satellite.
The entire satellite search process takes about 5 to 6 seconds. It takes a little longer to connect to the satellite, about 20 seconds. After the connection is successful, the interface will display the satellite phone and satellite information buttons together. We only need to select the communication method as needed.
We first tested the satellite phone functionality. After clicking the “Dial” button, the phone will automatically call the system’s own dialer program. During the dialing process, to obtain the best satellite signal, the mobile phone needs to be kept in the best position at all times. If it deviates from this position, noise will occur during the call.
Therefore, in the call interface, the phone will also provide a small window to guide users in real time on how to maintain the best position for the best call experience.
In addition, OPPO Find X7 Ultra Satellite Communication Edition is the first mobile phone to support handset satellite calls. On the call interface, just click the hands-free button to switch to handset mode.
At the same time, the system will give a prompt, recommending that users hold the phone in a lower position when using it, and do not hold the phone close to the face as they usually do when making calls, because this may block satellite signals, cause signal loss, and interrupt calls.
It can be seen from these details that OPPO has made great efforts in satellite communication experience, always taking user needs as the starting point, and striving to provide the best communication experience.
In the text message interface, the OPPO Find X7 Ultra satellite communication version provides multiple sets of text content, and users can edit and enter multiple text content by themselves.
Secondly, above the text content, we can also choose to send location information at the same time. At this time, the system will send the text content edited by the user and the longitude and latitude information to the recipient, and also attach a jump link to the Amap map.
Moreover, when sending a message, if it deviates from the satellite search range, the system will also pop up a small window to guide the user to connect.
At the receiving end, users can view the current accurate location of the person asking for help through the map interface and can use the navigation function of Amap to go to the location to provide timely assistance.
Cameras
OPPO Find X7 Ultra debuts a full-focus four-camera module. For the first time, the main camera is equipped with Sony’s LYT900 super one-inch CMOS, which has a 1.6μm single pixel area and up to 50 million effective pixels. It outputs 12.5 million pixels by default. It is equipped with a 1G7P lens group and f/1.8 aperture, 23mm equivalent. Focal length, supplemented by OIS optical anti-shake technology, ensures that every shot is clear and stable.
OPPO Find X7 Ultra is equipped with two periscope telephoto lenses, which are 3X optical zoom (native 2.7X 65mm focal length), equipped with Sony IMX890 outsole CMOS, and 6X 135mm focal length, and the sensor is Sony IMX858.
Among them, the 3X telephoto lens has a 1/1.56-inch actual photosensitive area and a 1μm single pixel, while the 6X super telephoto lens has a 1/2.51-inch photosensitive area and a 0.7μm single pixel. Both support floating prism OIS anti-shake. No matter how far or near, you can easily capture every wonderful moment.
The ultra-wide-angle lens sensor is equipped with Sony LYT600, a 1/2-inch photosensitive unit, 0.8-micron single pixel size, f/2.0 aperture, 14mm equivalent focal length, and supports 123° FOV.
Based on the parameters and specifications of the above four telephoto lenses, OPPO Find X7 Ultra directly breaks the ceiling in terms of imaging.
After several months of iteration of the imaging algorithm, its photo quality has also been significantly improved. In this regard, we also used the new version of Find X7 Ultra to take many sample photos, and then we will take a look at its actual image performance.
Main Photographer
In daytime scenes, OPPO Find X7 Ultra has gone through several system iterations to effectively control the overexposed or underexposed areas of the images captured, ensuring that every part of the photo can be properly exposed, and the color expression of the picture can be comprehensively improved.
Moreover, in backlit scenes, the dynamic range of the picture has also been significantly improved, and it can correctly handle the interlaced light and dark relationship of light and shadow, giving the picture stronger rendering power and penetration.
3x periscope telephoto
The 3x outsole periscope telephoto, thanks to the advantages of the outsole, can significantly reduce noise in photos, which means that even when shooting at high sensitivity settings, the resulting image will not have a rough pixelation effect. This maintains the delicacy and clarity of the picture.
Shooting some brightly colored flowers can accurately capture and reproduce the vivid colors of the flowers, and it does not add excessive saturation, but can accurately show the reality of the colors, making the flowers in the photos look natural and vibrant.
Even in a floral environment with complex and varied colors, X7 Ultra can distinguish and display each color in detail, thereby capturing the subtle color gradients and contrasts in the flowers.
When shooting against buildings in backlit scenes, it can also maintain a balance of light and dark, showing a rich sense of layering and three-dimensionality.
6x periscope telephoto
When shooting with a 6x periscope telephoto, not only can you capture clearer image details, but there is no problem with white balance distortion, ensuring that the color of the image is true and natural.
Secondly, when zooming to more than 10 times (10 times cropping), through recent optimization of the image, the image does not appear blurred or out of focus, and the outline and shape of the object remain clear. Compared with the longer shots taken by the earlier version, The focus sample has better details and a more layered picture.
Super wide angle
Under the ultra-wide-angle lens, the distortion control on both sides of the screen is excellent, and the resulting pictures can maintain a high degree of accuracy. When capturing a wide landscape, it can ensure that the entire scene is recorded evenly and realistically.
Game test
To differentiate the OPPO Find X7 Ultra satellite communication version from the regular version, it is directly provided with 1TB of storage. We also conducted game tests on the machine.
For the game test, we conducted it in an office environment at 25 degrees Celsius, using two popular mobile games “Genshin Impact” and “Honkai Impact: Star Rail”, using the highest image quality + the highest frame rate supported by the device (image quality takes precedence) ) conduct game testing and record the frame rate and body temperature performance during the game.
1. Original God
In the Genshin Impact mobile game, in the highest image quality + 60 frames mode, the frame rate is stable at 60 frames, with an average of 59.38FPS. There are almost no obvious fluctuations. It is quite good for a mobile phone that focuses on imaging to achieve such a level.
After the game, the maximum temperature on the back of the fuselage was 41.7 degrees Celsius, and there was almost no feeling of hotness when holding the phone horizontally during the game.
2. Collapse: Star Dome Railway
Honkai Impact: Star Dome Railway mobile game, in the highest image quality + 60 frame mode, ran a 10-minute test in the Xingchahai Center. The output of 60 frames was stable for about 4 and a half minutes. Later, due to the temperature control strategy, there was a relatively frame rate has a steady downward trend. Although the frame is dropped, during the game test, the picture did not feel frustrating at all. The maximum temperature on the back of the fuselage is 39 degrees Celsius.
