Han 5g users actually use 5g signal for only 15%

According to the “June South Korea 5g user experience report” released by the British market research agency open signal, when using 5g smartphones in South Korea, the actual time to connect 5g signals is only 15% of the time used, Yonhap reported. From the proportion of 5g connection time of each communication company, SK Telecom accounts for 15.4%, the highest among the three major communication companies. Followed by LG U + and KT, 15.1% and 12.5% respectively. At present, the 5g commercial service NSA (non independent Networking) mode in Korea shares equipment with LTE network. Where 5g cannot be connected, the signal will be automatically converted to LTE.

According to people in the telecommunications industry, the coverage of 5g in South Korea is narrow, and most of the network is connected to LTE indoors. Moreover, due to the large battery consumption of 5g mobile phone, it is difficult to successfully connect to 5g signal in the boundary area covered by the signal.

Foreign media: British Prime Minister Johnson announced that he would gradually stop using Huawei Technology in British 5g network

According to Reuters, citing the daily telegraph, British Prime Minister Boris Johnson expects to phase out Huawei Technology from Britain’s 5g network construction as soon as this year.

It is learned that at present, British government officials are drafting suggestions, hoping to stop installing new Huawei equipment in 5g network within six months and speed up the demolition of installed equipment and technology.

Previously, GCHQ mentioned its security concerns about Huawei in its report. The US sanctions against Huawei will force the company to use untrusted technology, which may increase the potential risk. The report is expected to be submitted to Johnson this week.

Johnson’s spokesman said earlier this week that officials would soon complete a review of the impact of the latest U.S. sanctions aimed at cutting Huawei’s ties with U.S. chip manufacturers.

After the merger, T-Mobile shut down sprint’s 5g network

According to foreign media fiercewireless, the US operator T – Mobile has completely shut down the sprint 5g network in the United States after its full acquisition of sprint.
