Palo Alto ( California, US): February 1 2016: Who better to help us understand what MU-MIMO means for us that the man widely known as the Father of MIMO -- India-born emeritus professor at Stanford University, Dr Arogyaswamy Paulraj?
It is exactly 20 years since he invented the MIMO standard and obtained a patent jointly with another Indian and Stanford don, Dr Tom Kailath.
"The increased data rate offered by MIMO is distributed across multiple users simultaneously - instead of a single user as in ordinary MIMO", he told IndiaTechOnline, but adds a caution: "11ac works at 5 GHz and is better at going through walls in the home or office. 11ad works at 60GHz and can deliver higher speeds but it doesn't penetrate walls and is useful only within the room " (Which is why products like the TP-Link Talon combine 11ac with ad )

Dr Paulraj who is also known in India as the naval officer-leader of the team which developed the country's first indigenous sonar anti submarine defence system, has received the Marconi Prize for his MIMO work - an honour he shares with Internet greats like Google search creator Larry Page, mobile phone inventor Martin Cooper and Internet protocol author Vint Cerf.
In recent weeks he became only the second PIO to be elected to the Chinese Academy of Engineering, a position he will take up in June.
