Sundar Pichai, the chief executive of Google, has been put in charge of its parent company Alphabet, after co-founders Larry Page and Sergey Brin announced they were stepping down. The 47-year-old said the pair had set up a "strong foundation" on which he would "continue to build". Pichai's life story is remarkable, and his rise to the top of Google is an endorsement of India's standing in the global technology industry - and equally, a reassuring reminder of the so-called "American Dream". Pichai was born and schooled in Chennai, India. He captained his school's cricket team, leading it to win regional competitions.

Wearable technology that can predict cancerous growths'several months' before they form are just around the corner, according to one technology expert. Nokia's chief says the firm is working on a scanning device that will pick up on biomarkers that indicate the conditions needed for abnormal cell growth to happen. A number of other medical innovations have also been envisaged that will make use of ultra-fast 5G mobile internet networks in the future. That includes remote surgery conducted from across the world, as well as ambulances that are able to transmit data to a hospital ahead of its arrival.

AT&T has revealed plans to roll out next generation 5G mobile internet in a dozen U.S. cities by the end of the year. If it hits the deadline, it would make the firm, which is America's second-largest wireless carrier, the first U.S. company to introduce the technology. New 5G networks are expected to provide speeds at least 10 times and up to maybe 100 times faster than today's 4G networks, depending on the type of systems used. However, AT&T refused to say where mobile 5G will be offered, what phone or phones the service will work on or the precise speeds consumers can expect.

Ultra-fast mobile broadband could soon be with us, thanks to a prototype 5G network currently under development. The system uses small antennae to send data between two micro signal towers, either based on the ground or in the air, at high speed. This could overcome one of the key hurdles of 5G technology, by avoiding the need for huge masts to transmit signals above buildings and other obstacles.

The Samsung-US network relies on small multi-directional antennas for line-of-sight connections.
