Japan’s Rakuten Mobile and Germany’s Telefonica Deutschland said that telecom operators shouldn’t really look at developing everything on their own rather bring in partners to develop technologies and solutions.

Rakuten Mobile chief technology officer Tareq Amin said that it is impossible to develop everything internally or have skill sets that cover everything end-to-end.

Chief technology and information officer at Telefonica Deutschland (O2 Germany), Mallik Rao said that a telecom operator can develop things in-house, but there has to be a “right balance.

“Telefonica developed the entire prepaid in house…unless it is adopted globally, unless you have a scale, you can’t sustain over a longer period. My belief is any solution should be at least regional, at least global, if not universal across the world,” he said in a fireside session at the event.

Their comments come in reply to a question posed on Reliance Jio’s approach to build 5G in-house during ETTelecom’s Digital Telco virtual summit.

“We have seen CDMA, which could not sustain for quite a long period of time. So it is important.. I’m sure RIL would be completely looking at as a global scale and what I strongly believe in participating and also leveraging the technology,” said Rao.
