Cutting edge technology

Introduction: In last year's MWC, Huawei actually revealed the upcoming model of the 5G baseband chip, the Barong 5000. Today, Huawei held a 5G conference in Beijing and officially released the Barong 5000.

Remember the last 5G commercial chip released by Huawei at MWC last year – Baron 5G01? Although the chip was the world's first 5G commercial chip at the time, Huawei also released a 5G CPE (5G user terminal) product based on this new product, but this chip is not suitable for miniaturized mobile terminals such as smart phones. Therefore, if Huawei's mobile phone wants to support 5G, it must wait for the subsequent launch of the 5G baseband chip for mobile phones.

▲Barong 5G01, such a large 5G chip obviously can't be stuffed into the "sweet body" of the smartphone.

On the MWC last year, Huawei actually revealed the upcoming model of the 5G baseband chip, the Barong 5000. Today, Huawei held a 5G conference in Beijing and officially released the Barong 5000.

As we all know, the 5G chips that have been released by major chip manufacturers, such as Qualcomm Xiaolong X50, Intel XMM8060, Samsung Exynos Modem 5100, and MediaTek Helio M70 are 5G single-mode chips, so we want to support 5G network. At the same time, to achieve compatibility with 4G/3G/2G networks, they must be combined with the original 4G baseband. And this will undoubtedly greatly increase the cost.

In contrast, the Barron 5000 is a multimode 5G chip that implements independent networking (SA) and non-independent networking (NSA) modes on a single chip. Supported by the 5G New Air Interface (NR) standard, it also supports access technology for 4G/3G/2G networks.

The design of Barron 5000 multimode single chip not only avoids the design complexity, power management and device appearance adjustment of single mode 5G chip, but also in terms of power consumption, size and scalability. Both have brought about significant improvements. In addition, the cost is also greatly reduced compared to the 5G chip 4G chip combination.

However, it seems that Yu Chengdong called Baron 5000 the world's first 5G multimode chip. Because Intel was in November last year.The first 5G multimode modem XMM8160 was released. The chip also supports 5G SA and NSA standards, while being backward compatible with 4G/3G/2G networks.

In terms of specific indicators, Yu Chengdong said that the Baron 5000 chip is smaller than the fingernail, and has a speed increase of more than 10 times compared with 4G. It supports TDD and FDD bands and supports millimeter wave, which is the highest in the millimeter wave band. The downlink rate can reach 6.5Gbps, which is more than twice as fast as competing products (it seems to be slightly exaggerated here. Before the Qualcomm Xiaolong X50 in the millimeter wave band, the data transmission speed of 4.51Gbps was realized in the test environment).

It is also worth mentioning that the Baron 5000 also added support for the R14 standard V2X technology, which also made the Baron 5000 the world's first 5G chip supporting V2X.

V2X is a cellular vehicle networking technology. It is a technology for real-time perception of the surrounding conditions of vehicles by means of wireless communication between the vehicle and X (people, vehicles, road infrastructure, background). Compared with the camera, radar, lidar and other technologies commonly used in autonomous driving technology, V2X has a wider range of use, it has the ability to break through the visual dead angle and across the obstruction, and can share real-time driving with other vehicles and facilities. State information, and prediction information can also be generated by a research algorithm. In addition, V2X is the only vehicle sensing technology that is not affected by weather conditions, and it will not affect its normal operation regardless of rain, fog or strong light. Therefore, the current V2X technology is also a hot spot in the field of autonomous driving and car networking.

Obviously, the release of the Barong 5000 also indicates that Huawei will continue to enter the automotive networking market.

5G CPE Pro: The world's fastest 5G commercial terminal

After the official launch of the Barong 5000, Huawei also announced the launch of the world's fastest 5G CPE based on the Baron 5000. According to reports, this 5GCPE supports Huawei smart home protocol, its coverage enhancement is up to 30%, WI-Fi6 is supported, and the multi-device Internet access rate is increased by about 4 times. It is the fastest WiFi device at present.

Although Yu Chengdong did not announce more details of the Barong 5000 at the press conference, he announced the terminal equipment 5G based on the Barong 5000.Some test data for CPE Pro.

According to data released by Huawei, the peak rate of 5G CPE Pro can reach 3.29Gbps, and the average rate can reach 3.22Gbps.

In addition, 5G CPE Pro also uses Huawei-designed high-frequency antenna to achieve small size and high signal sensitivity. For different 4G/5G frequency requirements, flexible antenna selection is possible, which also makes 5G CPE Pro Compared with the previous generation, the antenna is reduced by 20% while achieving a 30% improvement in signal coverage.

Finally, according to Huawei's Yu Chengdong, Huawei will release its first folding screen 5G mobile phone at the MWC show in February.
