“3G speeds support live video streaming to notebooks”— Pallab Talukdar, CEO, Fujitsu India
True notebook mobility occurs not when the connection becomes wireless, but rather when the connection becomes wireless and untethered from a physical location. Wireless wide-area data services—specifically 3G service offerings—offered by the major cellular carriers are making true notebook mobility a reality today. And notebook manufacturers like Fujitsu have realised that, just like 802.11, wireless wide-area capabilities need to be embedded into notebooks to optimise the usability and manageability of the technology.
Pallab Talukdar, CEO, Fujitsu India, spoke to Uma Bansal, deputy editor at EFY, about the importance of 3G-ready laptops, how these will revolutionise the mobile workforce and their plans for India.
