1. Foreword: Handset, hands-free dual-mode two-way satellite call OPPO to create
Nowadays, the integration and application of satellite communication technology in the field of mobile phones has made significant progress, which can provide a means of contact with the outside world in remote areas such as oceans, deserts, forests or so-called "information wastelands" without traditional signal coverage.
This is a valuable communication resource for people who explore, work, or live in these areas.
However, until now, there has been a general limitation in mobile phones equipped with satellite communication: users can only make voice calls through hands-free, which has reduced the usefulness 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 X7 Ultra satellite communication version, with the help of innovative antenna beam design and exclusive multi-satellite antenna pattern control technology, for the first time to achieve handset and hands-free dual-mode two-way satellite call.
Because of the addition of the handset mode, it not only improves the flexibility of satellite communication in emergency situations, but also significantly improves the convenience of daily use of satellite phones.

3. Communication ability test: handset and hands-free dual-mode two-way satellite call is the same as making a phone call
The OPPO Find X7 Ultra Satellite Communication Edition is OPPO's first satellite communication mobile phone and the first device to support 5.5G mobile communication.
5.5G, also known as 5G-Advanced, is an advanced version of 5G technology and is seen as a transitional technology between 5G and 6G.
The OPPO Find X7 Ultra Satellite Communication Edition's 5.5G network limit speed is up to 300% higher than that of the 5G network, leading the mobile phone into the 10 Gigabit mobile era.
In terms of satellite communication capabilities, Find X7 Ultra Satellite Communication Edition is the first mobile phone to support handset and hands-free dual-mode two-way satellite calling, combined with innovative antenna beam design, so that the satellite communication antenna fully covers the top position of the mobile phone, and based on OPPO's exclusive multi-satellite antenna pattern control technology, so that when satellite communication, the mobile phone can adjust the satellite pattern in the head and hand state, so that the antenna beam can accurately point to the satellite.
This makes the mobile phone satellite call experience upgrade from the traditional "satellite intercom mode" to the more intuitive "satellite phone mode".
This innovative technological improvement allows users to enjoy a more efficient way of communicating even in extreme environments.
In other words, with an optimized antenna design, users can easily make satellite calls in their ears as naturally as if they were using a regular phone. This dramatically improves communication reliability and convenience in challenging environments.
In this regard, we have also done a series of tests on the satellite communication capabilities of the OPPO Find X7 Ultra satellite communication version.
Compared with the regular version, the OPPO Find X7 Ultra Satellite Communication Edition has an additional "Satellite Network" option in the settings interface, which can be clicked to use the satellite communication function.
When using satellite communication, the first thing to do is to find an open and unobstructed field in front of you, and use the GPS and gyroscope of your mobile phone to shake the figure eight to calibrate according to the action shown in the diagram.
Next, the search for satellite signals begins.
To ensure signal reception, once you have found the general direction of a nearby available communication satellite, follow the prompts on the page and gently turn your phone to make sure it is aligned with the satellite.
The whole satellite search process takes about 5~6 seconds, and the connection time to connect to the satellite is a little longer, about 20 seconds, and the interface will display the satellite phone and satellite information button together after the connection is successful, we only need to choose the communication method as needed.
We started by testing the satellite phone feature.
After clicking the "Dialing" button, the phone will automatically call the system's built-in dialer program.
In order to get the best satellite signal during the dialing process, the mobile phone needs to be in the best position at all times.
If you deviate from this position, there will be a murmur during the call.
Therefore, in the call interface, the phone also provides a small window to guide the user in real time on how to maintain the best position for the best call experience.
In addition, the OPPO Find X7 Ultra Satellite Communication Edition is the first mobile phone to support handset satellite calling, and in the call interface, you can switch to handset mode by simply tapping the hands-free button.
At the same time, the system will give a reminder that users should hold the phone in the lower position when using it, and do not hold the phone close to their face as they usually do when calling, as this may block the satellite signal, resulting in signal loss and interrupting the call.
From these details, it can be seen that OPPO has really put a lot of effort into the satellite communication experience, and has always taken user needs as the starting point and strived to provide the best communication experience.
On the SMS interface, the OPPO Find X7 Ultra Satellite Communication Edition provides multiple sets of text content, and users can edit and enter multiple text contents 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, longitude and latitude information to the recipient, and also attach a jump link to the AutoNavi map.
Moreover, when the message is sent, 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, the user can view the current accurate location of the help-seeker through the map interface, and can use the navigation function of AutoNavi Map to go to the location in order to provide timely assistance.
Fourth, the image test: the resolution of the double periscope is greatly improved, and the image quality and color are delicate
OPPO Find X7 Ultra首发了全焦段四摄模组。
For the first time, the main camera is equipped with Sony Guangyu's LYT900 super one-inch CMOS, with a single pixel area of 1.6μm and up to 50 million effective pixels, with a default output of 12.5 million pixels, equipped with a 1G7P lens group and f/1.8 aperture, 23mm equivalent focal length, supplemented by OIS optical image stabilization technology, to ensure that every shot is clear and stable.
The Oppo Find X7 Ultra is equipped with two periscope telephoto lenses, namely a 3X optical zoom (native 2.7X 65mm focal length) equipped with Sony IMX890 outsole CMOS, and a 6X 135mm focal length with a Sony IMX858 sensor.
Among them, the 3X telephoto lens has an actual photosensitive area of 1/1.56 inch and a single pixel of 1μm, while the 6X ultra telephoto lens has a photosensitive area of 1/2.51 inch and a single pixel of 0.7μm.
Judging from the specifications of the above four telephoto lenses, the OPPO Find X7 Ultra directly pierces the ceiling level in terms of imaging.
After several months of iteration of the image algorithm, the quality of its photos has also been significantly improved.
We've also taken a number of samples with the new Find X7 Ultra, so let's take a look at it in action.
- Main camera
In daytime scenes, the Oppo Find X7 Ultra has gone through several system iterations to effectively control the overexposed or underexposed areas, ensuring that every part of the image is properly exposed, and the color expression of the image is improved in an all-round way.
Moreover, in the backlit scene, the dynamic range of the picture has also been significantly improved, which can correctly handle the relationship between light and shadow, so that the picture has a stronger rendering power and penetration.
- 3x periscope telephoto
The 3x periscope telephoto, thanks to the advantage of the outsole, is able to significantly reduce noise in the photo, which means that even when shooting at high sensitivity settings, the resulting image will not appear coarse pixelated, thus maintaining the fineness and clarity of the image.
Photographing brightly colored clusters of flowers can accurately capture and reproduce the vivid colors of the flowers, and without over-saturation, they can accurately show the realism of the colors, making the flowers in the photo look natural and vibrant.
Even in complex floral environments, the X7 Ultra is able to distinguish and display each color in detail, capturing subtle color gradients and contrasts in the flowers.
When shooting buildings in backlit scenes, it is also able to 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 does it capture sharper details, but it also doesn't suffer from white balance distortion, ensuring true and natural colors.
Second, at zooms above 10x (10x crop), recent optimizations ensure that the image is not blurred or out of focus, the contours and shapes of objects remain sharp, and the details are better and the image is more layered than in the telephoto samples taken in the previous version.
- Ultra-wide-angle
In the ultra-wide-angle lens, the distortion control on both sides of the frame is excellent, and the resulting image maintains a high level of accuracy, ensuring that the entire scene is captured evenly and realistically when capturing wide landscapes.
5. Game test: Genshin Impact High quality can run at full frame
In order to make a difference from the regular version, the Oppo Find X7 Ultra satellite communication version is directly given 1TB of storage, and we also tested the device in the game.
In the game test session, we conducted the game test in an office environment of 25 degrees Celsius, using two popular mobile games "Genshin Impact" and "Honkai: Star Dome Railway", using the highest image quality + highest frame rate supported by the device (image quality first), and recording the frame rate and temperature performance of the body during the game.
1. Genshin Impact
Genshin Impact Mobile Game is in the highest image quality +60 frame mode, the frame rate is stable at the 60 frame level, with an average of 59.38 FPS, and there are almost no particularly obvious fluctuations.
After gaming, the maximum temperature on the back of the fuselage was 41.7 degrees Celsius, and it was almost not hot to hold the phone horizontally during the game.
2. Honkai: Star Dome Railway
Honkai: Star Dome Railway mobile game, the highest image quality +60 frames mode, in the Xingcha Sea Pivot running map for 10 minutes test, the first 4 and a half minutes or so can stabilize the output of 60 frames, and then due to the temperature control strategy, resulting in a relatively stable frame rate decline trend, although the frame drops, but in the process of game testing, the picture does not have the slightest frustration.
The maximum temperature on the back of the fuselage is 39 degrees Celsius.
6. Charging and battery life: The 5000mAh large battery can be fully charged in less than half an hour and the battery life can reach 11.5 hours
The OPPO Find X7 Ultra Satellite Communication Edition has a built-in 5000mAh large-capacity battery, supports up to 100W wired fast charging, and takes into account 50W wireless flash charging.
In this regard, we also tested its charging and battery life.
- Charging test
We conducted a charging test with the screen off, and the battery started charging from 1%, the battery was more than half in 10 minutes, and the battery reached 86% in 20 minutes, and finally it took 26 minutes to fully charge, and it was fully charged in less than half an hour.
- Endurance test
For the endurance test, we use a professional endurance test tool - the battery dog produced by Fast Technology for testing.
In terms of test items, the default power test will be carried out to 20%, and at the same time, all test items including CPU high voltage, CPU multi-threading, AI recognition, picture browsing, video playback and web browsing will be checked, and the real load will be restored to the greatest extent by simulating user usage scenarios, infinitely close to the real power consumption.
During the test, in order to keep the environmental variables of all models tested in order to maintain the same and ensure the accuracy of the test results, Battery Dog automatically adjusted the brightness of the screen to 50%, and turned off the auto-brightness and adjusted the volume to 30%.
After continuous and uninterrupted measurement of the battery dog (1080P resolution), the power consumption from 100% to 20% took 10 hours, 01 minutes and 10 seconds, which can be converted into a full battery life of about 11.5 hours, such a strong battery life, which is rare in the mobile phone that focuses on images.
With this battery life, it is not a problem for ordinary users to turn on 2K resolution for a day of daily use.
