A reliable supply of computer chips is essential for Arnob Roy, the co-founder of Tejas Networks.
His company, based in Bangalore, India, supplies the equipment behind mobile phone networks and broadband connections.
“Essentially, we provide the electronics that carry traffic across telecom networks,” he says.
That requires special chips designed for telecoms tasks.
“Telecom chips are fundamentally different from consumer or smartphone chips. They handle massive volumes of data coming simultaneously from hundreds of thousands of users.
“These networks cannot go down. Reliability, redundancy and fail-safe operation are critical – the chip architecture has to support that,” Roy says.
Tejas designs many of those chips in India, a country well known for its expertise in designing computer chips (also known as semiconductors).
It’s estimated that 20% of the world’s semiconductor engineers are in India.
“Almost every major global chip company has its largest or second-largest design centre in India, working on cutting-edge products,” says Amitesh Kumar Sinha, Joint Secretary of India’s Ministry of Electronics and Information Technology.
What India lacks is companies that manufacture semiconductors.
So Indian firms like Tejas Neworks design the chips they need in India, but then have them manufactured overseas.
