Is it true that Huawei shut down Canada's 5g?

It is true that Huawei closed Canada's 5g, and Huawei has already withdrawn from Canada.

The fifth generation mobile communication technology (5G for short) is a new generation broadband mobile communication technology, which has the characteristics of high speed, low delay and large connection, and is the network infrastructure to realize man-machine interconnection.

20 18 June, 3GPP released the first 5G standard (Release- 15), which supports 5G independent networking and focuses on enhancing mobile broadband services. In June 2020, the Release- 16 version standard was released, focusing on supporting low-latency and high-reliability services, and realizing support for applications such as 5G car networking and industrial Internet. The Release- 17(R 17) version of the standard will focus on realizing differentiated IOT applications and realizing medium and high-speed Dalian connection, and it is planned to be released in June 2022.

In order to meet the diverse application scenarios of 5G, the key performance indicators of 5G are more diversified. ITU defines eight key performance indicators of 5G, among which high speed, low delay and large connection are the most prominent features of 5G. The user experience rate reaches 1 Gbps, the delay is as low as 1 ms, and the user connection capacity reaches 1 10,000 connections /km2.
