  • 1G

    Launched by Nippon Telegraph and Telephone in 1979, 1G was first introduced to the citizens of Tokyo. By 1984, the first generational network covered all of Japan, making it the first country to have 1G service nationwide. It wasn’t until March 6, 1983, that Ameritech introduced 1G to the United States. Soon after, Canada got coverage in the mid-1980s.

  • 2G

    Following the success of 1G, 2G launched on the Global System for Mobile Communications (GSM) in Finland in 1991.

    2G provided significant mobile talk advancements, introducing encrypted calls. 2G improved sound quality, reducing static and crackling noises while you were talking. 2G’s download speeds were also significantly faster
    The 2G network also allowed us to transfer data bits from one phone to another. 2G also gave us some basic smartphone functionality.

    2G introduced text messages

  • 3G

    Deployed for the public in Japan by NTT DoCoMo in 2001, 3G focused on standardizing vendors’ network protocol. In turn, users could access data from anywhere, which allowed international roaming services to begin. Compared to 2G, 3G had four times the data transferring capabilities reaching up to 2 Mbps on average.
    What made 3G revolutionary, though, was the ability to surf the internet, and stream music on mobile. In Canada, download speeds today are almost 6 Mbps.

  • 4G

    Introduced for commercial use in Norway near the end of 2009, 4G offered today’s standard services.
    Mobile devices needed to be specifically designed to support 4G.
    However, when 4G first started, it wasn’t actually 4G. The ITU-R decided that LTE (Long-term evolution) could be labelled as 4G.
    When 4G first came out, what you were seeing was 3.9G or 3.95G instead.

  • 5G

    South Korea was the first country to offer 5G in March 2019. The 5th generation was rolled out by KT, LG Uplus, and SK Telecom – all South Korean telecom providers. 5G in Canada has already been introduced in major cities.
    The median 5G download speed in Canada is 169.46 Mbps. That’s already 205% faster than 4G!
    A big difference between 4G and 5G is its latency and bandwidth size. 5G has a larger frequency range (between 30GHz and 300 GHz),
