Huawei Technologies Co., Ltd. shared a video on a personal Weibo, a three-minute video is the "Huawei Brand Story" in the CCTV "National Brand Plan", in-depth interpretation of how to carry consumers trust In all aspects, the quality of the product is created into the international pass, and Huawei brand is created into an international brand.
A fragment in the video shows that Huawei mobile phone high quality mobile phone signal, thanks to advanced antenna test equipment, it is the first way to ensure the quality signal of the mobile phone. As Huawei signal detector is in the video: "If the phone signal is from weak to strong metaphors, we will ensure that the gun is ten rings, and it is not bad." The antenna test system is self-evident on mobile phone signal, and even the quality of mobile phone.
The device in the video is a solution SG 24, which is created by the French MVG Group to deal with the performance test of wireless equipment. With the broadcast of the video, well-known manufacturers in this global antenna test measurement began to gradually be known.
SATIMO SATIMO Source of the French MVG Group was established in 1986, in successive acquisition of electromagnetic field measurement system design and manufacturer Antennessa / FR, antenna measurement and test solution vendor Orbit / FR (along with its AEMI), absorbing and Shielding darkroom Solutions Manufacturer Rainford EMC Systems, and established a global partnership with Ar / Amplifier Research (US), its industry status is increasingly consolidated.
At present, MVG includes four major business units: Antenna Test Measurement Business Department, provides fast, accurate measurement of antenna solution, and the company's 81% business volume; electromagnetic compatible business unit (EMC), R & D is in line with various The dark room of the electromagnetic compatibility test requires industry and academic research institutions for telecommunications, aerospace, defense, automotive, electronic and EMC, 16% of the company's business comes from the department; environmental and industrial control business units are committed to R & D, production Efficient radio frequency monitoring and alarm system to ensure the radio frequency safety of the public and telecommunications, accounting for 3% of the business; the last one is the medical care and security business department under construction.
Leading 5G wireless connection at the forefront
MVG Group Orbit / Fr German Liability Company General Manager and 5G Project Leader Aleksis Anterow and MVG Group Global Sales Director Gianni Barone received its latest high-frequency segment, super precision test Product Starlab 50GHz and new concepts of portable integrated antenna measuring tool "Little Big Lab", and analyzes test cases and test results.

According to the explanation of Aleksis Anterow, the MVG test system includes two probes techniques: single probe and multi-probes, with multiple probe systems from source company Satimo, mostly used for 6-18GHz telecom bands, advantage is fast and accurate measurement and super stable mechanical design ORBIT / FR, which is acquired later, its advantage is that single probe technology can measure any frequency band, even up to 110g frequency band, which is generally used in aviation and defense fields. By integrating two technologies, Starlab 50GHz becomes the world's first multi-probe system advantage, but also high-frequency segment test.
Starlab 50GHz
"In 3G, 4G antenna test, the antenna can be contacted, and the traditional test method is feasible. However, in the 5G antenna test, there is no large-scale antenna array, but the antenna and equipment are integrated, so it is not possible In touch, it is necessary to test in OTA air downloads. At the same time, the test object is not only antenna, but the entire equipment and system. This is a new challenge to the industry to test the industry. "Aleksis Anterow said,
In multi-antenna testing, the number of MVG products does not limit the number of antennas. In Massive MIMO test, the number of antennas supported by the device can be supported by 256. In the latest MIMO test plan in CTIA, MVG is one of the world's only one of the official certified test equipment suppliers. Aleksis Anterow believes that 5G testing can be different and adjustable for multi-antenna arrays, and the tester can be set to a multi-beam, pointing to one place; in high frequency, there is a narrow beam; when there is interference, the direction can be adjusted. Test and LTE protocols of less than 60 GHz are similar, and the tests greater than 60 GHz can be adjusted to achieve different test results.
Further, in consideration of 50 times the 5G transmission speed of 4G, the frequency range of its test also extends to millimeter waves, resulting in a traditional RF test, the coaxial cable test method cannot meet the demand, thereby giving birth to the dark room, MVG can also Provide corresponding solutions and turnkey system projects.
Gianni Barone said that 3G / 4G comes from the global unified standard, China is in followed, in the upcoming 5G era, China will have been actively participating and led. He summarized the 5G development strategy of MVG from three aspects, including: cooperation with manufacturers of production network equipment; actively participating in standardization development, including cooperation with 3GPP; accelerating new products for 5G testing. In the past two years, MVG has delivered 5G antenna test equipment for some companies that produce 5G products, such as Hui, and Sony Lund from Sweden.
