4G means fourth-generation wireless, the technology of broadband mobile internet communications that supercedes the third generation or 3G. According to the ITU (International Telecommunication Union), a 4G network requires a mobile device to be able to exchange data at 100 Mbit/sec. A 3G network, on the other hand, can offer data speeds as slow as 3.84 Mbit/sec. Although Carriers which use orthogonal frequency-division multiplexing (OFDM) instead of time division multiple access (TDMA) or code division multiple access (CDMA) sometimes market their services as 4G.

4G is just a cosmetic term in most cases than being a technical specification, though carriers justify in using the 4G badge because it tells the consumer that they can expect significantly faster data speeds over any 3G network. Carriers build 4G data networks using Long Term Evolution (LTE) or Worldwide Interoperability for Microwave Access WiMAX. It has, however, been debated whether first-release versions should be considered 4G (using LTE). The 4G system was originally envisioned by the Defense Advanced Research Projects Agency (DARPA).
