What are the differences between 2G, 3G, 4G LTE, and 5G networks?

  • Simply, the "G" stands for "GENERATION". While connected to the internet, the speed of the connection depends upon the signal strength that is shown in abbreviations like 2G, 3G, and 4G, etc. on any mobile device. Each generation of wireless broadband is defined as a set of telephone network standards that describe the technological implementation of the system.

  • The aim of wireless communication is to provide high quality, reliable communication just like wired communication and each new generation represents a big leap in that direction. Mobile communication has become more popular in the last few years due to fast reform in mobile technology. For the comparison of 2G, 3G, 4G, and 5G we first need to understand the key features of all these technologies.

    SECOND GENERATION (2G)

  • 2G refers to the second generation of mobile networks based on GSM. The radio signals used by the 1G network were analog, while 2G networks were digital. 2G capabilities were achieved by allowing multiple users on a single channel via multiplexing. During 2G, Cellular phones were used for data also along with voice. Some of the key features of 2G were:

    • Data speeds of up to 64 kbps

    • Use of digital signals instead of analog

    • Enabled services such as SMS and MMS (Multimedia Message)

    • Provided better quality voice calls

    • It used a bandwidth of 30 to 200 KHz

    THIRD GENERATION (3G)

  • The 3G standard utilizes Universal Mobile Telecommunications System (UMTS) as its core network architecture. 3G network combines aspects of the 2G network with new technologies and protocols to deliver a significantly faster data rate. By using packet switching, the original technology was improved to allow speeds up to 14 Mbps. It used Wide Band Wireless Network that increased clarity. It operates at a range of 2100MHz and has a bandwidth of 15-20MHz. Some of the main features of 3G are:

    • Speed of up to 2 Mbps

    • Increased bandwidth and data transfer rates

    • Send/receive large email messages

    • Large capacities and broadband capabilities


    International Mobile Telecommunications-2000 (IMT-2000) were the specifications by the International Telecommunication Union for the 3G network. Theoretically, 21.6 Mbps in the max speed of HSPA+.

    FOURTH GENERATION (4G)

  • The main difference between 3G and 4G is the data rate. There is also a huge difference between 3G and 4G technology. The key technologies that have made 4G possible are MIMO (Multiple Input Multiple Output) and OFDM (Orthogonal Frequency Division Multiplexing). The most important 4G standards are WiMAX and LTE. While 4G LTE is a major improvement over 3G speeds, it is technically not 4G. What is the difference between 4G and LTE?

  • Even after it was widely available, many networks were not up to the required speed of 4G. 4G LTE is a “fourth generation long term evolution”, capable of delivering a very fast and secure internet connection. Basically, 4G is the predetermined standard for mobile network connections. 4G LTE is the term given to the path which has to be followed to achieve those predefined standards. Some of the features of 4G LTE are:

    • Support interactive multimedia, voice, video

    • High speed, high capacity and low cost per bit (Speeds of up to 20 Mbps or more)

    • Global and scalable mobile networks.

    • Ad hoc and multi-hop networks.

    FIFTH GENERATION (4G)

  • 5G uses the rarely used radio millimeter bands in the 30 GHz to 300 GHz range. Testing of 5G range in mmWave has produced results approximately 500 meters from the tower. Using small cells, carriers using millimetre wave for the deployment of 5G can improve overall coverage area. Combined with Beamforming, small cells can deliver extremely fast coverage with low latency.

  • Low latency is one of 5G’s most important features. 5G uses a scalable orthogonal frequency-division multiplexing (OFDM) framework. 5G benefits greatly from this and can have latency as low as one millisecond with realistic estimates to be around 1 – 10 seconds. 5G is estimated to be 60 to 120 times faster than the average 4G latency.


  • With speeds of up to 10 Gbps, 5G is set to be as much as 10 times faster than 4G. Following is a brief comparison of 2G, 3G, 4G, and 5G.

    2G vs 3G vs 4G vs 5G

  • Each generation in some way has improved over its predecessor. There is a lot of ground to compare the cell networks over. Following is the comparison between 2G, 3G, 4G, 5G

  • The comparison of 2G, 3G, 4G, and 5G clearly show the differences in the technologies. The comparison of 2G, 3G, 4G, and 5G also makes it evident that 5G is going to be one of the most ambitious leaps in the history of cell network technologies.
