Last Thursday, Huawei once again released the Pura 70 series "without warning", causing a sensation on the whole network with its new brand concept and product positioning. Lei Technology was the first to experience the Pura 70 Ultra of the Pura 70 series, and conducted an in-depth evaluation of the imaging capabilities of the Pura 70 Pro+.

Just when the whole network focused on the design, image, and performance of the Pura 70 series, Xiaolei unexpectedly found that the Pura 70 series had "quietly" achieved another leap in satellite communication functions - Pura 70 Pro, Pura 70 Pro+, and Pura 70 Ultra realized satellite image transmission for the first time.

It has to be said that since Huawei debuted the satellite messaging function on the Mate50 series in 2022, its progress in the field of satellite communication can be described as rapid, from short text messages at the beginning, to satellite calls, and then to today's satellite picture messages, step by step to improve the satellite communication experience of mobile communication equipment.

But when it comes to the new function of "satellite picture message", Xiao Lei can't help but be curious, since there is already satellite message and satellite call, what is the meaning of picture message? And using satellite to send pictures, is the use experience good? With this question, Xiao Lei personally went to Baiyun Mountain to experience a "satellite picture message" to see how far Huawei's black technology has evolved.

Satellite picture message, the experience is really silky

Last year, Xiaolei tested the Mate60 ProSatellite call function, and it was mentioned that whether it is the operation process of opening the satellite call function, or making and connecting to the satellite call, it is simple, fast and convenient. On the Pura 70 Pro+, the experience remains silky smooth.

The Pura 70 Pro+ supports Beidou and Tiantong dual satellite communications, the latter being operated by China Telecom. On the main menu of the phone's settings, all the functions related to satellite communication are integrated into the "satellite network" section, which is simple and straightforward.

Compared with the Mate 60 Pro, the new "Picture Message" function of the Pura 70 Pro+ is hidden in the "Connect to Beidou Satellite Messages" column, click on this item to go to the "Connect" function. At present, there is no need to open an additional service package to use the satellite images sent by Changlian, and it is completely free to use, but like the early satellite message function, it is limited to 30 pieces per month.

Since you need to use satellites to send messages, you still have to follow the rules of use, such as connecting to satellites outdoors in an open area, trying not to be obscured by buildings or trees, and more importantly, as a "life-saving function", it can only be used when you can't connect to wireless and mobile networks.

According to the rules, we tried to search for satellites and connect satellites in the relatively empty square halfway up the Baiyun Mountain, and the whole process was still very smooth, and the star search speed was significantly faster than that of the Mate 60 Pro, and there was not much difference in connection speed. It's worth noting that if you need to send a picture message, you still need to hold the handheld position for a little longer than a normal message or call, but considering that sending a picture is not a simple matter, the wait is worth it.

Satellite connection and messaging is already one of the specialties of the current flagship model, and Xiaolei has also tried many times in previous evaluations, and here we still focus on the image messaging function.

After selecting the image to send, the Pura 70 Pro+ automatically generates a "compressed" image to ensure efficient satellite delivery to the specified device. In addition to the pictures being sent, Huawei also thoughtfully attached the time and latitude and longitude so that professionals could carry out the rescue, which was well received.

When a picture message is sent to a non-Huawei device, it is presented in the form of text message + connection, but there are also priorities, such as longitude and latitude information will provide text information, while image content and specific maps are linked, which has the advantage of improving the efficiency of transmitting core information, and professionals can immediately go to the rescue after seeing the latitude and longitude information. As for privacy, it has always been the most important part of Huawei, and even if the recipient clicks on the link of the picture information, it needs to be confirmed again through the SMS verification code to further ensure privacy and security.

Limited by the byte length, the image content of the Pura 70 Pro+ will be greatly compressed, and the receiver can only receive an image of about 100KB when it sends a picture of about 6MB. Although detail has been severely lost, it is still not a problem to confirm the location and landmarks.

From the perspective of experience, Huawei's satellite communication function has formed a unique system, which is suitable for most ordinary consumers in terms of operation process and transmission efficiency. However, compared with satellite messages and satellite calls, satellite image messages may not seem so "magical", but is this really the case?

One-click sending, AI mapping?

Compared with text messages and voice calls, pictures may be the best solution for ordinary people to save themselves.

For example, although Huawei's initial satellite message only supports 19 characters, the shortcuts provide the most core rescue information, so that users in distress can be rescued quickly. In fact, with the increasing number of consumers of hiking, hiking and adventure, these ordinary people often lack professional training and are likely to be unable to accurately describe their location and situation, which is a great obstacle to rescue efforts.

In many cases, when we are lost in the woods and mountains, it is difficult to find the right words to describe the troubles we are experiencing, and we even become incoherent because of panic. At this time, if you can provide picture information to professional rescuers, then the efficiency of rescue will be greatly improved.

So, is Huawei's picture information really reliable?

Although Huawei uses "compression" technology to process images to make their file sizes conform to the standards of satellite messages, from the actual experience on the Pura 70 Pro+, Huawei seems to use AI to recognize, analyze, and reassemble images, so that there is no need to worry about the size of the images taken at hand and not being processed correctly.

In addition, Huawei's processed images retain as much as possible the most conspicuous "details" of the images, for example, in the images we took during the test, the most iconic building is a gazebo, and the Pura 70 Pro+'s AI processing perfectly preserves this part.

What's more, because the size of the picture is greatly compressed, its sending efficiency is greatly improved. According to Xiaolei's measurement, even when the satellite signal is only 50%, the waiting time for sending will not exceed 30 seconds, and for most users, the picture message can be sent smoothly. Even if the sending fails, the user can click the relevant prompt and choose to resend it with a single click, which reduces the process of repeated confirmation and improves the efficiency of calling for help.

If there is a fly in the ointment, it is that the creation of image messages is still not fast enough. For example, many times the person in distress may not have so much energy to take a photo in the camera app, and then go back to Changlian to select the contact, select the photo, wait for processing, and finally complete the sending. If Huawei can provide the option to take photos directly in Changlian, it may be able to further simplify the distress process.

It is true that under the limited satellite resources, Huawei can realize the satellite picture message function through the artificial intelligence large model solution, which is already the embodiment of its years of technology accumulation in the field of AI and communication.

Write at the end

As a pioneer of mobile satellite communication, Huawei has been continuously improving the practical scenarios of this feature in the past few years, such as simpler and simpler operation processes, richer content carriers, and higher delivery efficiency. Picture messages can be said to be a detailed extension of Huawei's "life-saving function", but Huawei wants to do much more than that.

At the end of last year, Huawei demonstrated a number of technologies and patents at the 6G Mobile Communications Conference, the most notable of which is the satellite Internet function, although this is not new in the professional field, but it is difficult to realize it on the mobile phone.

Judging from the completion of satellite image messages, Huawei seems to have found a correct and unique direction, and perhaps in the near future, we will see Huawei launch a satellite Internet function, completely overturning the crime of "satellite communication is not practical".

The Beijing International Automobile Exhibition (Beijing Auto Show) will be held from April 25th to May 4th, with the theme of "New Era, New Automobiles", which is the vane of "Cars from Electrification to Intelligence".

At that time, including BYD, Xiaomi, AITO, Xiaopeng, Weilai, ideal, Extreme Krypton, Jiyue, Changan Deep Blue and other head brands will all appear, in addition to the new model "big competition", the advancement of autonomous driving technology, the evolution of intelligent cockpit and the combination of AI large models and cars, will be important highlights. Lei Technology's "Pay attention to electric vehicles, understand more intelligent" account tram will send a reporting team to Beijing to conduct first-line professional reports, so stay tuned.
