The International Telecommunication Union (ITU), the Geneva-based affiliate of the United Nations that governs issues concerning information and communication technologies, has set 2020 as the target year for completing the international standardization of 5G technologies so as to pave the way for its mass adoption, according to a roadmap the ITU refers to as "IMT-2020." However, there are signs that the ITU's timeframe may be too conservative, taking into consideration the boldness shown by international tech giants as they vie for dominance in the 5G industry at this early stage. In a market environment already featuring fierce competition, Chinese telecommunications companies are not only active participants, but also rising stars among the top ranks. (Xinhua/Joan Gosa)
