Among the technologies that we will see a lot of will be Near-field Communications (NFC), which could become the primary medium for transferring data over short ranges. A handful of smartphones from Nokia and Blackberry are already enabled, but 2012 could be the year in which they will finally get something to do.
Another upcoming technology to that will facilitate device-to-device connectivity in the future is Wi-fi Direct. Certified by the Wi-fi Alliance, the new technology will let Wi-fi devices connect with each other quickly to share content, sync or even print with or without traditional network available. This technology claims to offer data rates ranging between 54 Mbps to 250 Mbps within a 100-meter range depending upon the 802.11 a/g/n. This isn’t meant to replace traditional Wi-fi and as it doesn’t require any hardware specification to work, any Wi-fi enabled device can be upgraded to Wi-fi direct with the help of the software.
While India is still struggling with the 3G rollout, the world is gradually graduating to 4G networks. Although 4G is still a far-fetched dream for Indians, internationally we will see a lot many 4G enabled devices being launched.
