5G

The subscriber appetite has historically driven new mobile technology generations every 10 or so years.

• 1982: First Generation (1G — analog voice only) systems with large heavy phones and poor network quality were introduced.

• 1992: Second Generation (2G) was deployed with improvements in signaling and hardware that were primarily aimed toward the voice market but, unlike the first-generation systems, used digital modulation to enhance call quality and enable new applications such as Short Messaging Services (SMS) and other low-data-rate (9.6 to 237 kbps) wireless applications.

• 2001: Third Generation (3G) was introduced, providing a significant leap over 2G, with much higher data rates (typically ranging from 400 Kbps to 16 Mbps), significant increases in network voice capacity, along with better channel quality and — most important — support for advanced services and applications, including multimedia.

• 2012: Fourth Generation (4G) was deployed (some call it 4G-LTE). This was an all IP-network with increased speeds ranging from 21 Mbps to 1 gigabit speeds with wireless network latencies of 5 milliseconds. The wireless service providers were able to reduce network-per-megabyte costs with this new technology, while responding to increasing bandwidth demands from subscribers. One of the goals of LTE was to make the mobile Internet experience as good as or better than that offered by the wired broadband access systems deployed today.

• 2020: 5G is on schedule to be deployed in this timeframe.
