Huawei's Kirin chip has emerged as a "dark horse" in the 3G chip competition. The history of Huawei's Kirin chips dates back to 2004, when they were primarily used for industrial applications, supporting network and video functions, but not yet entering the smartphone market. In 2009, Huawei launched its first K3 processor for smartphones, marking a significant milestone in China’s mobile chip industry.
Today, smartphones are essential tools for internet access, messaging, and streaming videos anytime, anywhere. Major phone manufacturers continuously strive to enhance their products by increasing screen sizes, boosting performance, and adding more features. However, many consumers often overlook one of the most critical aspects of a smartphone: its network connectivity performance.
Without reliable network connectivity, a smartphone is essentially in "flight mode," rendering it similar to a PDA from the 1990s. Most users lack the technical knowledge or tools to evaluate a phone's network performance, as testing such capabilities requires expensive equipment costing over a million dollars.
In June 2017, China Mobile released the “White Paper and Terminal Quality Report,†offering an objective evaluation of smartphone quality in the market. This report highlighted the strong performance of Huawei's Kirin chips in various models.
As shown in the report, the Huawei P10, Glory V9 (with Kirin 960), and the Huawei nova Youth Edition (with Kirin 658) ranked among the top models across different price ranges. In the 3,000 yuan and above category, three Kirin-powered devices secured top positions, with the Huawei P10, P10 Plus, and Mate 9 Pro leading the way.
In communication capability tests, the Huawei P10 Plus, Glory V9, and Changxiang 7 Plus (all equipped with Kirin chips) topped their respective price categories. These results demonstrate the strength of Huawei’s baseband technology in real-world scenarios.
To better understand how these chips function, it's important to recognize that smartphones rely on two key components: the application processor (AP) and the baseband chip. While the AP handles tasks like video, image processing, and gaming, the baseband chip manages signal transmission, modulation, and demodulation, making it crucial for communication between the device and the network.
The baseband chip also runs network protocol stacks, which determine how the phone connects to and switches between base stations. Optimized algorithms can significantly improve connection speed, especially in weak signal areas, enhancing user experience.
Mobile phone certification tests are usually conducted under ideal conditions, but real-world environments are far more complex. To achieve superior connectivity, Huawei invests heavily in optimizing baseband design and algorithms through extensive network experience.
When evaluating Kirin chip performance, factors like VoLTE call stability, download speed, and interference resistance are considered. The Kirin 960, for instance, demonstrated excellent performance in weak signal scenarios and high-speed environments.
Download speed is influenced by interference, which occurs when multiple users share the same frequency band. Error correction coding and power control mechanisms help reduce this interference, and these processes are managed by the baseband chip.
Carrier aggregation technology further enhances speed by combining multiple frequency bands into one. This requires coordination between the radio frequency and baseband chips to ensure optimal performance, especially in challenging conditions like high-speed movement.
VoLTE, which uses LTE networks for voice calls, relies on end-to-end service guarantees. This means that both the network and the device must work together to maintain call quality. The Kirin 960 excels in this area, particularly in low-signal environments.
Overall, the success of a smartphone depends on seamless collaboration between the network and the device. Behind every smooth call or fast download lies years of research, optimization, and innovation by communication engineers.
**Huawei Kirin Processor Models**
The Kirin series includes several generations:
- **Kirin 9 Series**: Starting with Kirin 910, followed by Kirin 920, Kirin 930, Kirin 950, and Kirin 960. These chips powered popular devices like the Huawei P7, P8, P9, P10, Mate 7, Mate 8, Mate 9, and the Glory 6, 7, 8, and 9 series.
- **Kirin 6 Series**: Including Kirin 620, Kirin 650, and Kirin 658. These chips were used in budget-friendly models such as the P8 Youth, Nova Youth, and Glory 4X, 5C, and 6X.
- **K3V2 Series**: One of the earliest chips from Huawei, used in early smartphones like the Honor 3 and P7.
Each generation of Kirin chips brought improvements in performance, efficiency, and connectivity, solidifying Huawei's position in the global semiconductor market.
