In the 5G era, Chinese manufacturers are set to play a more prominent role on the global stage. As the first mobile communication standard developed by China and adopted worldwide, 5G has given the Chinese industry a historic opportunity to break through and leap forward at a deeper level. This is not just about catching up—it's about leading the next phase of technological evolution.
By the end of 2017, the 3GPP NSA (Non-Standalone) standard was finalized, marking a significant step toward the establishment and operation of commercial 5G networks. Today, China’s IMT-2020 (5G) Promotion Group held its third-phase specification conference for 5G technology R&D trials in Beijing, releasing the first batch of specifications for the third round of testing. Through these trials, it is expected that the core components of the 5G industry chain will reach pre-commercial readiness by the end of 2018, accelerating the development of 5G and laying the groundwork for large-scale trials and commercial deployment. This marks a crucial milestone before full commercialization.
Spreadtrum has been actively positioning itself in the 5G landscape. According to Wang Yanhui, secretary-general of the China Mobile Alliance, as the mobile phone industry has grown over the past few years, so too has the entire supply chain, including integrated circuits. Companies like Spreadtrum have emerged as key players. Spreadtrum has made 5G R&D a top strategic priority, with dedicated resources and budgets allocated for this purpose. Ziguang has also provided strong support for its 5G initiatives.
Currently, Spreadtrum has established a dedicated 5G product team, emphasizing the need to align with national strategies and work under the guidance of the state and the group. The goal is to leverage 5G technologies and collaborate with global communication leaders to return to an equal playing field and become a leading communications company.
Unlike previous generations of mobile networks, China now holds a stronger position in the 5G ecosystem, excelling in standard-setting, commercial progress, chip development, and terminal research. Breaking monopolies and achieving autonomy requires a strong patent portfolio. Spreadtrum began pre-research on 5G core technologies as early as 2015, while its standardization team worked to deeply understand and interpret all aspects of the standards, ensuring solid support for prototype and chip development.
In addition to internal efforts, Spreadtrum has actively collaborated with domestic universities and research institutes. This includes sharing patents, promoting standardization, and conducting joint research projects, which have significantly enhanced its patent reserves.
On the technical front, Spreadtrum’s 5G product team has been working on both terminal prototypes and chips simultaneously with the standardization process. The prototype was based on a private draft similar to the 3GPP specification, successfully completing air interface tests with base station equipment from vendors. It passed the two-stage scale test conducted by the Ministry of Industry and Information Technology.
On the chip side, the algorithm platform evolved in sync with each 3GPP meeting. Within a month after the NSA standard was finalized, a floating-point simulation platform implementing all features was released. Based on 3GPP requirements, Spreadtrum completed the final architecture of the terminal chip and provided preliminary evaluations on chip area and power consumption.
On January 16, the IMT-2020 (5G) Promotion Group released the first batch of specifications for the third phase of 5G R&D trials. Spreadtrum followed closely, using pilot V2 prototypes and chips to meet the technical requirements of 5G test terminals and complete key technology verification and interoperability testing with equipment. A chip-level verification platform was used to evaluate 5G terminal solutions, and the first chip supporting the 3GPP R15 5G standard was launched according to the third-phase timetable.
Looking ahead, Spreadtrum aims to become a top-tier player in the 5G chip market. In 2018, it participated in the Ministry of Industry and Information Technology’s three-phase 5G field tests, starting with prototype platforms and later moving to chip reference designs. By the end of 2018, the first mobile chip supporting the 3GPP R15 5G standard was expected to be launched.
5G represents a massive opportunity. According to the China Institute of Information and Communication, by 2030, 5G could drive direct economic output of 6.3 trillion yuan, add 2.9 trillion yuan to the economy, and create 8 million jobs. Indirectly, it could generate 10.6 trillion yuan in total output, 3.6 trillion yuan in added value, and 11.5 million jobs.
However, challenges remain. Technologically, one of the biggest hurdles is the flexibility of the 5G standard. While the framework is defined, many physical layer parameters—such as bandwidth, subcarrier spacing, frame structure, and reference signals—are highly configurable. This creates a vast number of possible configurations, making it challenging to design chips that can support them all.
To address this, Spreadtrum has built in sufficient software processing capabilities and worked with key industry partners, including equipment vendors and operators, to define product profiles within the 3GPP framework. This helps clarify what is "reasonably achievable" in terms of specifications.
In the market, despite slower growth in the smartphone sector, 5G is seen as a catalyst for innovation. Spreadtrum believes that the slowdown at the end of 2017 doesn’t mean the industry is entering a cold winter. After rapid growth, the market is now stabilizing, and new applications will drive further expansion. With 5G, smartphones could offer new experiences in AI, AR/VR, 4K/2K, and more, supported by strong government backing.
Battery life and 5G flexibility will pose design challenges for terminal chips, but they also open the door for innovation. The 5G industry must work together to develop new applications that fully leverage the potential of this next-generation network.
As Wen Ku, director of the Information and Communication Development Department of the Ministry of Industry and Information Technology, pointed out, the next steps include following international standards, accelerating pre-commercial equipment development, building comprehensive R&D platforms, and synchronizing frequency planning for 3.5GHz and 4.9GHz bands.
Wang Yanhui also emphasized that in the 5G era, China has greater influence in setting global standards. With China leading in 5G commercialization, Chinese equipment manufacturers and brands now have a chance to capture the first wave of opportunities in the global market.
In 5G terminal chip design, companies must keep pace with evolving standards. As the standard is locked down, the industry follows suit. Beyond smartphones, 5G will unlock new opportunities in industrial internet, smart manufacturing, autonomous driving, drones, personal entertainment devices, and cloud applications.
4G Industrial Router
Analysis of advantages and disadvantages of 4G industrial routers
First, what is the classification of industrial routers?
Industrial Router (a communication device that can be divided into 2G routers, 2.5G routers, 3G routers and 4G routers according to network standards.
For users, you can communicate with the Internet by setting a default gateway on your PC or network device. In fact, the default gateway configured for network devices is the packet export for network devices. After the packet is sent to the Ethernet port of the router, the router performs the next job, so the router is an Internet relay.
Second, how do industrial routers work
So how does the router forward the packet? Just like getting somewhere, you need to place a route. This route is a routing table. This routing table contains all the destination network addresses owned by the router, as well as the best path to reach those networks through the router. This is because there is a routing table, so the router can forward packets according to the routing table. That's how routers work.
Understand what is an industrial router and how it works, it is not difficult to understand the advantages and disadvantages of the router. Here we focus on the advantages and disadvantages of 4G industrial routers.
Third, the advantages of 4G industrial routers
For networks interconnected via single-protocol industrial-grade wireless routers, the same or different protocols can be used at layers 1-2. Layer 3 uses the same routable protocol and requires the same or compatible protocols at layer 4 and beyond.
Industrial routers can perform complex routing calculations and are suitable for connecting three or more large networks with complex network topologies.
Industrial-grade routers can isolate broadcast storm information in the source network, thereby reducing and mitigating the impact of broadcast storms.
Multiprotocol industrial wireless routers can be used as network interconnection platforms using different communication protocols because they can connect to the network using different communication protocols.
The entire network router can also be used as a bridge to handle non-routable protocols.
Industrial 4G routers enable you to isolate unnecessary communications so that the interconnected network maintains its own area of independent management and control, thereby improving network security performance. Therefore, industrial-grade 4G routers are commonly used as firewalls to restrict access to the internal and external networks (Internet) of the LAN, as well as the internal areas of the LAN, and act as network masking.
It can provide reliable transport and prioritization services, and industrial LTE routers do not need to maintain a persistent connection between networks that communicate with each other.
Complete Netcom router network segmentation improves network performance and reduces host load.
Third, the advantages of 4G industrial routers
High price
When installing an industrial LTE router, it is difficult to install and maintain due to the large number of initial configurations
If you spend more time processing, the transmission performance of the entire network of the industrial router will decrease.
Unlike Bridges, routers across industrial networks are protocol-related. Each advanced protocol used for network connectivity must be configured separately, and an industrial-grade network-grade router with a separate protocol for each protocol must be provided.
Industrial Netcom routers do not support non-routed protocols, so when interconnecting multiple networks, there are restrictions on the protocols used by the connected networks.
