Let's see the difference between 5g + connectors!

According to the data published by the global mobile Providers Association (GSA), by September 2020, the number of 5g networks put into commercial use in the world has reached 106, an increase of 14 in the last month alone, which proves the accelerated development of the 5g era. This year's new crown disease does not seem to slow down the commercial pace of 5g. According to GSA's analysis, at present, the penetration rate of 5g in the global population has reached 7%. It is estimated that 20% of the global devices will access 5g network by 2025.

1、 Different positioning

5g positioning urges people to put crazy enthusiasm and great expectations into 5g: if cellular wireless communication technology solves the connection between people anytime and anywhere from 2G to 4G and constructs the wireless Internet world, 5g will expand this connection to a broader field of the Internet of things, and 5g will become the framework for everything to connect the world in the future.

There is a standard Metcalf's law in the network field, which is to the effect that the value of the network is directly proportional to the square of the number of network users. The value growth space of cellular wireless technology before 5g is finally limited by the total world population. When 5g meets the ceiling of development, the number of users - people or machinery - at least increases. With the expansion of application, the potential value exceeds people's imagination.

In order to realize the vision of interconnection of all things and shape all-round players, 5g should meet the following three application scenarios in the same network architecture:

1. EmbB (enhanced mobile broadband)

Due to technologies such as millimeter wave and super large MIMO, it is generally considered that the peak speed of 5g can reach 1Gbps, 10 times that of 4G, which will make many applications that people could not realize before (such as high-definition video wireless transmission) become a reality, and it is also easy to support new applications requiring big data transmission such as virtual reality / ar.

2. Urllc (high reliability and low delay communication)

When the very low network delay is less than 1ms, the system has high redundancy and reliability. 5g penetrates into the fields with strict real-time requirements, such as automatic driving, industrial control, telemedicine and so on.

3. Mmtc (large machinery type communication)

For IOT applications requiring low power consumption, low speed and remote connection, large-scale connection is provided. 5g can cover a wide range of applications in smart cities, smart meters, public facilities management, wearable devices, smart homes and other fields, and the market imagination space is huge.

From this almost no dead corner application scenario setting, we can see the ambition of 5g Unified Wireless Jianghu. In other words, anyone who can grasp the opportunity of 5g can take the ride of rapid development.

2、 Different structures.

5g draws a large picture during positioning, which includes the wireless connection scene within the scope of imagination. The hegemonic positioning of 5g determines that structural planning and design must also be hegemonic.

The familiar 4G / LTE network structure can be simplified into network edge devices (mobile phones and tablets, etc.), base stations (connecting edge devices and transmitting data to local switches and other devices for processing), and local central clouds (data centers of communication networks). However, this network structure obviously can not meet the needs of 5g.

Relatively speaking, 5g edge devices are more diversified, and the communication requirements of different devices vary greatly. The number of terminals and data throughput that need to be connected by a single base station also increase significantly. Because it needs to support very low network delay within 1ms, millimeter wave is adopted, and the transmission distance is limited, it is necessary to configure more dense cellular base stations. Therefore, the 5g network architecture should also be adjusted accordingly.

III Connector Different.

The change of 5g network structure will be transmitted to the upstream hardware, and new hardware solutions are needed to adapt to this change. Among them, connector products are no exception.

In the hardware system,Connector It usually does not occupy the most important C-bit, but as a connecting part for transmitting data and power supply, it can ensure the stability and reliability of the system,Connector Very important, mistakes in selection and application often bury imperceptible dangers.

these Connector The application scenarios are different, but in order to match 5g, additional constraints need to be met.

1. High performance.

As mentioned above, the 5g distributed network structure makes the edge data center undertake more computing and processing tasks, and the high-performance interconnection scheme previously seen in the cloud data center also lands in the edge data center.

2. High reliability.

5g base stations need to adapt to the challenges of different environments, so Connector Better reliability and durability.

3. Miniaturization.

The function of 5g equipment is more complex, which requires more content in unit space, and puts forward higher demands for the connection density of connectors.

4. Diversity.

The above 5g use cases have the characteristics of diversity, which means to deal with the diversity of connector product portfolio and achieve the best results. This requires locking the most appropriate connector product according to the specific application.

In short, 5g brings many new design challenges to hardware connection, and its large-scale commercial configuration also brings huge business opportunities. This requires Connector The product optimizes the adaptability around 5g requirements, develops different products, and finds a new application foothold in this important wireless technology upgrading.
