With the saturation of the market and the intensification of competition, it seems less and less important whether there are Nokia branded mobile phones in the future, and the name may once again attract the attention of the industry. It should be the communication infrastructure, such as 5g technology. Last year, Nokia group announced a US $16.6 billion merger with Alcatel lucent. In terms of business revenue, the new company surpassed Ericsson and became the global communication manufacturer second only to Huawei. Nokia recently announced that they and U.S. operator U.S. cellular have jointly tested 5g signal technology based on 28ghz, with a rate of up to 5Gbps (the handheld terminal used is unknown), a delay of less than 2ms, and can synchronously carry six 4K HD video streams.
The test is divided into indoor and outdoor, in which the indoor is carried out in U.S. cellular's own experiment. In order to simulate the possible daily environment, obstacles are set up with trees, walls, windows, metal plates and so on.
In the current 5g progress, Huawei has a very fast pace, and Nokia & Alan, Ericsson and ZTE are also striving to be the first.
It is reported that 5g will no longer be divided into TD / FDD in the 4G era. It is expected that the witness of large-scale commercial is the 2020 Tokyo Olympic Games.
