Excuse me, which company developed WCDMA network technology?

Hello, WCDMA technology is a combination of European and Japanese technologies. It was first proposed by the European Telecommunications Standards Committee and the Japanese mobile phone operator NTT. Later, many companies invested in research and finally produced this 3G system with the widest application, the largest number of terminals, the fastest speed, the most mature industrial chain and the largest number of network-building countries.

At present, the global WCDMA basic patents are in the hands of about 27 foreign companies, among which Qualcomm, Ericsson and Nokia own most of the patents, and Motorola, NTT, Lucent and Internet Digital also own some WCDMA basic patents, covering the core technologies that WCDMA system can't leapfrog, such as spread spectrum communication. WCDMA standard patent distribution: Nokia (Finland) 35%; Ericsson (Sweden) 31%; Qualcomm (USA) 6%; Siemens (Germany) 5%; Another 22%.

I hope you are satisfied with my answer, thank you!
