What is NANO?

NANO is a new type of mobile phone interface developed by Siemens mobile phone department in 25. Its durability and speed connectivity are better than those of the previous interface started from S55, and its dustproof ability is stronger because it is flatter and smaller. Later, its mobile phone department was taken over by BENQ, and it also continued to be used in some mobile phones using Siemens system. Shortly after BENQ6 announced the abandonment of its German factory in 26, Siemens also withdrew all related patents and technologies, including NANO port and S-GOLD series system.
