The Mobile World Congress, the largest and most influential exhibition in the field of global communication, was held in Barcelona from February 25 to 28, and was attended by many well-known global enterprises engaged in the communication industry.

     This year is the first year of 5G commerce. Looking back the 2019MWC, under the background of verious fields starting 5G commerce work one by one , gives new meaning to the World Mobile Communications Congress (2019MWC), which opened on February 25.In the industry, MWC is the highlight of products, the technical strength of the vane, this year 5G has become a hot topic, also shows that the 5G network has been officially boarded the stage of history.

     It is worth noting that in 2019, most of the recommended stocks of SEC are communication stocks, which belong to 5G concept stocks, because 5G is pre-commercial in 2019.The provisional license issued by China in 2019 will complete the trial spectrum allocation and stand on the same starting line as developed countries.Unlike 4G, 5G is a cross-era technology. It will penetrate into all vertical industries from the Internet of Things era, and be applied in all aspects of production and life, especially for the telecommunications industry.

      At present, China is in the process of the transition from 4 to 5 G. Copper to optical fiber. Although most of the users have not been fully covered, the overall coverage of optical fibers has exceeded 80%.It is mainly used for the construction and maintenance of optical cables in optical communications. It can quickly splice in the process of avoiding splicing loss as far as possible.With the landing of 5G network, it has a great impact on the products of the related communication industry, and it also drives the market sentiment of the whole communication sector.

      With the issuance of temporary licenses by the Ministry of Industry and Information Technology, operators' confidence has been enhanced and the concrete implementation of 5G commercial and communication infrastructure construction has been accelerated.Meanwhile, the overall rhythm of the relevant policies of the 5G in 2018 lays the main tone for the first year of the construction of the 5G in 2019.

      5G, with its characteristics of high bandwidth, low latency and broadband Internet of Things, will bring huge changes to our lives.Tumtec will follow the lead of MWC, adapt to market changes, and devote itself to building a world-renowned brand of welders, becoming the world's most reliable manufacturer of optical fiber fusion splicers (equipment and instruments).
