China Mobile's Everest camp is 6500 meters above sea level.

　　ChinaNews.net client, April 30 (Reporter Wu Tao) On the 30th, China's 5G sent good news again, and 5G signals officially covered the summit of Mount Everest, the world's highest peak.

　　The reporter learned from China Mobile and Huawei on the 30th that China Mobile and Huawei have worked hard for several days to open the world's highest 5G base station at the 6,500-meter elevation camp on Mount Everest to achieve the coverage of 5G signals on the mountain climbing route and peak of Mount Everest. .

　　At this point, China Mobile ’s five 5G base stations at the 6,500-meter elevation campground at Mount Everest, the transitional campground at 5,800 meters altitude, and the 5,300-meter base camp at Everest have all been put into use for Mount Everest, scientific research, environmental monitoring, high-definition live broadcast, etc. The activities provided communication guarantees, which effectively demonstrated the strength of China's rapid development of 5G.

5G signal officially covers the summit of Mount Everest

　　It is understood that this action is a special action for "Mount Everest on 5G" and has been officially launched since April this year. The action plan is to build 5 5G base stations in the form of SA + NSA networking in the Everest Base Camp at 5300 meters above sea level, the Transition Camp at 5800 meters and the Forward Camp at 6500 meters, while providing Gigabit broadband and dedicated line access.

　　Specifically, the operation will lay 25 kilometers of optical cables in 5,300 meters, 5,800 meters, and 6,500 meters high and cold areas, transfer 8 tons of network construction equipment and life support materials through shoulder-bearing pig packs, and use Huawei equipment to build and open 3 4G base stations and Five 5G base stations and 12 network maintenance and optimization personnel are on duty 7 * 24 hours in an area above 5300 meters above sea level to ensure smooth and good network performance in the Everest area.

　　In addition, the operation also upgraded, renovated, maintained and strengthened the 177-km transmission trunk line around the Everest guarantee zone and the node computer rooms along the line, and opened up the Lhasa-Chengdu core network.

　　According to reports, in addition to meeting the basic communication needs of staff in the base camp, Huawei has also launched 5G + 4K slow live broadcasts to the public in conjunction with media such as Migu Video to "Appreciate Mount Everest in the Cloud" anytime and anywhere. At the same time, in view of the high altitude of Everest and the difficulty of on-site operation and maintenance, Huawei HoloSens SDC innovates the "3 free 9 self" capability, supports one-click tuning of video quality, one-click fault positioning, and the device is always online, allowing 6500 meters of Everest live broadcast become possible.

After many ups and downs

　　The reporter noted that on the 20th, China Mobile had sent a message that it was expected to complete the construction and opening of two 5G base stations and all points of the 6,500-meter advance camp by April 25. Why is the time delayed?

　　The reporter learned from people familiar with the situation that in the past few days, there was a continuous snowstorm in the area of ​​5800 meters and above in Mount Everest. Considering the physical condition and construction safety of the construction personnel, all the construction personnel and yaks were evacuated to the 5300 meters area and the opening time of the 6500 meters 5G base station was delayed Rear. After the 25th, the weather conditions improved and the construction staff sprinted again.

　　According to reports, in order not to damage the natural ecological environment in the core area of ​​Mount Everest, the construction plan design adopts the method of laying armored optical cables with the least damage to the natural environment to ensure that no excavation or damage will be done in the core area; During the construction process, a living area shall be set up in a unified manner, and domestic and construction waste shall be treated in a centralized manner.

　　In addition, in order to ensure the realization of the goal of laying the optical cable to the 6,500-meter forward camp, the construction and construction personnel should be trained in climbing in advance, and a responsibility letter should be signed to ensure the smooth and safe implementation of this work. In order to guarantee the operation, China Mobile sent more than 150 employees in charge of construction and maintenance. Huawei coordinated the technology delivery and network assurance team of more than 20 people to the area above 5300m above sea level for 7 * 24 hours to ensure the construction of the 5G network in the Everest region. And activation to ensure optimal network performance.

　　Why build a base station in an area as dangerous as Everest, where few people use the network? Ren Zhengfei, the founder of Huawei, said on May 18, 2019, whether Everest is on the south or north slope, the base station is basically installed by us. There are not many people on Everest. What money can I make? But there may be an Internet that can save the climber's life.

What kind of equipment can mount Everest?

　　Netizens who have watched the movie "Climber" must be very impressed. The Everest environment is quite bad, and this time the construction technology of 5G base stations is more complicated, the construction volume is larger, and the construction environment requirements are higher. It is understood that because the Everest Base Camp and the above areas belong to the National Nature Reserve, it is very difficult to move materials and enter the site.

　　In order to solve these difficulties, Huawei's 5G minimalist site and Zhijian all-optical network are used in this construction. It has a high degree of integration, small size, light weight, easy handling and easy installation, which effectively reduces the difficulty of Everest deployment. Moreover, the equipment must be resistant to low temperatures. According to reports, Huawei's 5G equipment can adapt to the extreme environment of Everest's low temperature and low pressure, ensuring long-term stable operation.

　　In addition, the highest site of 5G base stations deployed by China Mobile and Huawei is at an altitude of 6,500 meters, and there is still a drop of more than 2,000 meters from the summit of Mount Everest. In order to effectively cover the peak, this deployment of 5G base stations uses Huawei 64-channel Massive MIMO ( Large-scale antenna technology) products, through flexible beamforming and high vertical dimension gain, can better match the complicated mountain scene of Mount Everest.

　　At the same time, combined with Huawei's Massive MIMO technology and algorithm, the cell capacity and peak user rate have been greatly improved. According to on-site measurements by staff, the peak value of the downlink exceeded 1.66Gbps, and the uplink rate was as high as 215Mbps, which can effectively meet the requirements of 4K + VR HD live broadcast on Mount Everest.

　　Huawei said that in terms of hardware, related 5G products use chip technology with higher integration to continuously improve single-board integration. The product's low energy consumption is very necessary for Everest sites with difficult energy supply and protection of Everest's natural environment. .
