Near Field Communication
Near Field Communication or NFC is a technology that uses magnetic field to connect devices for wireless data transmission. Nokia launches this technology in model number 6131 in 2006. Near Field Communication is a short range wireless technology that can work up till a distance of a few centimeters. This technology was used for sharing content, streaming multimedia, multi player gaming and paring Bluetooth.
4G is the fourth generation of mobile communication technology standard. Till now 3G is still far from seeing mass adoption. This technology has IPv6 support with the browsing speed of up to 100 Mbps. It was launching this year but there are very few devices that support 4G connectivity.
WiFi 802.11 ad
WiFi is the primary and best wireless technology used for data transfer. This WiFi version supports the full HD videos and transfer large amount of data between two wireless devices. The wireless LAN protocol was divided into a, b, g, n, Ac and ad. The Wi-Fi version b, g and n are widely used in all the mobile communication devices. The first WiFi version was founded in 1997 which has the data rate of 2 Mbps. The WiFi 802.11 ad version is coming this February which will support date rate of 6.75 Gbps.
