What Is the Difference Between 3G and N & G Networks?

3G is a mobile telephone standard, while "N" and "G" are two wireless network standards.

3G is a standard for mobile telephone networks. It is officially called "International Mobile Telecommunications-2000" (IMT-2000). "N" and "G" refer to two related standards published by the Institute of Electrical and Electronics Engineers (IEEE). These are Wi-Fi standards for data communications.

Function

The IEEE's 802.11 suite of standards aims to define systems for Wireless LANs (Local Area Networks). Each publication is identified by the code 802.11, but is distinguished by a terminating letter. So 802.11n and 802.11g are among that body of work, and the standards they define are sometimes referred to as an "N" network, or a "G" network. The 802.11g is the most popular standard for Wi-Fi routers in the consumer market. Many 802.11g products started to emerge even before the standard was officially finalized. 802.11n adds Multiple Input Multiple Output (MIMO) capabilities to the 802.11g standards. This increases throughput from 54 Mbps (Megabits per second) to 600 Mbps.

Features

802.11n and 802.11g are principally concerned with wireless data networks. These networks can carry video streaming and voice. 3G is a standard for the transmission of voice, but 3G systems must also be able to carry video and data.

Differences

The 802.11 standards are meant for transmission of high rates of data over short distances. 3G cannot achieve the throughput achieved by Wi-Fi, but it operates over a much wider physical area.
