In the 5G era, what kind of chips do you need most?

Over the past 40 years, the evolution of data networks has also witnessed the rapid expansion of mobile storage, from the earliest flip phone to the smart phone; from 3G to 5G, it is not only a great progress in data transmission, 5G mobile phones need more storage capacity to calculate than early Blackberry machines.

From the figure below, we can see the storage capacity of mobile phones, from 0 bandwidth and 0 storage capacity of 1G network in early 1981 to 21.6Mbps bandwidth and 256MB storage of 3G network speed, to 1G bandwidth and 6G storage capacity of 4G network speed. The higher the network speed, the greater the storage demand of mobile phones.

Mobile phone data network transmission, like uploading 4K movies, content composition is mostly information and voice. It can also be connected to various devices, including sensors, parking timers, smart cars, wearable electronic devices, etc.

Today's communications services are built on computer calculus systems. SRAM and TCAM are replacing flash memory and DRAM devices in the past. There is even more room for storage.

TCAM Small File

High-speed TCAM (Tristate Memory Memory Storage) can be used as a filter for large data to reduce the pressure of processing data and greatly reduce the power consumption during standby. TCAM can search all data in one clock cycle and is faster than traditional RAM.

TCAM is a storage that supports network devices. It is mainly used to shorten the data search time. They can improve the speed of router search, classify data, and access control column permissions, so as to speed up data processing.

Although TCAM has a long life span, it is still not common. According to Jim Handy, chairman of objective analysis, the main reason is the high cost and the scarcity of suppliers. Handy also believes that traditional DRAM will be replaced by high-speed SRAM.

Network Elimination Rate Increases

Handy said that 40 years ago, the limitation that telecom networks still need long life has disappeared. In the past, telecom operators required products to be able to use for more than 30 years, but now, because of the rapid development of the network, telecom operators can use it for five to ten years.

This partly reflects the speed of development of the network. Handy also points out that in less than 10 years, the 4G network has been replaced by 5G. According to Craig McGowan, Senior Customer Manager of Meguiar Technologies, 5G is more like a network platform and the basis of data broadband networks.

Network fluency is also one of the advantages of 5G broadband Internet access, 5G can improve network delay speed, so that network speed no longer card. At the same time, McGowan said that ultra-low latency will be able to be used in AR and VR online games to a large extent.

Hiep Pham, vice president of storage company Virtium, said that the main goal of 5G is high-speed network fluidity. He believed that the demand for AI in future networks would increase, so high-frequency bandwidth was needed to process data.

It is expected that in the future, the boundaries between telecommunication networks and technology platforms will become increasingly blurred. The network will not only pursue sound quality and data transmission, but also support computer calculus and the Internet of Things. It includes industrial automation, self driving cars and smart city.
