4G internet is the 4th generation of mobile internet technology, successor of 3G technology which is most used broadband wireless internet access. Most of the mobile operators have almost 100 percent 3G internet coverage. Lately, the most of them are offering the 4G mobile internet. Do you really know what are exactly the 4G internet and 4G technology? According to International Telecommunications Union-Radio communications sector (ITU-R) the requirements for the 4G internet are:

  • Peak speed of 100 Mbps for high mobility communications (for cars and trains)
  • Peak speed of 1 Gbps for low mobility communications (for pedestrians and stationary users)

These requirements, set by ITU-R, are called International Mobile Telecommunication Advanced (IMT-Advanced) specifications.

Is there Real 4G Technology on the Market?

Today on the market, real 4G technology, defined by IMT-Advanced specifications is still very rares. All mobile operators are using a term “4G” in their marketing campaigns, but which one of them offers the wireless speed of 1 Gbps for their mobile subscribers. Y

Which Technologies are “4G technologies”?

Which technologies are 4G technologies? Which technology is used in the marketing campaigns of the mobile operators? They are the following technologies:

  • Mobile WiMAX – Worldwide Interoperability for Microwave Access
  • LTE – Long Term Evolution

The first Mobile WiMAX network was released in South Korea in 2006. The first LTE network was released in Norway and Sweden in 2009. In the United States, Sprint first released its Mobile WiMAX network in 2008, while MetroPCS was the first operator with the LTE service. In Europe all operators for the “4G internet” are using LTE technology and there are no available Mobile WiMAX networks.

Mobile WiMAX- Worldwide Interoperability for Microwave Access

WiMAX data rates

Mobile WiMAX (IEEE 802.16e) or MWBA – mobile wireless broadband access is called WiBro in South Korea. They are offering the wireless data rates of maximum 128 Mbps for downlink and 55 Mbps for uplink. Sprint is using Mobile WiMAX with the name 4G internet, even though it doesn’t fulfil the IMT advanced requirements for 4G. More about the WiMAX and how WiMAX works you can read in the article What is WiMAX and How WiMAX Works. WiMAX technology has lots of advantages and disadvantages. Read about the WiMAX technology all its pros and cons in the post Disadvantages of WiMAX Technology. Is the WiMAX the right choice. WiMAX is defined by the IEEE 802.16 family of standards for WMAN – Wireless Metropolitan Area Networks. More about the 802.16 read in the post 802.16 – Standard for Wireless MAN or WiMAX Network.

LTE – Long Term Evolution

LTE data rates

LTE is mostly called 4G or 4G-LTE, but its first version doesn’t fulfill IMT-Advanced requirements. Peak wireless data rate is 100 Mbps for downlink and 50 Mbps for uplink in 20 MHZ channel. LTE, working on the frequency channel with the bandwidth of 20 MHz and using the 4X4 MIMO antennas, can work on maximum wireless download data rates of 300 Mbps and upload data rates of 75 Mbps. The advanced version of LTE – LTE-Advanced will be a real 4G internet technology with the speeds up to 1Gbps for fixed and 100 Mbps for mobile users. Learn how are the voice calls deployed in the LTE in the post Voice over LTE (VoLTE) – the New Features in the LTE. I recommend that you check the post WiMAX vs LTE – What is a Better 4G Technology to find out what is the best 4G technology.
