Explanation:

• 5G is the 5th generation mobile network. It is a new global wireless standard after 1G, 2G, 3G, and 4G networks. 5G enables a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, and devices.
• 5G wireless technology is meant to deliver higher multi-Gbps peak data speeds, ultra-low latency, more reliability, massive network capacity, increased availability, and a more uniform user experience to more users. Higher performance and improved efficiency empower new user experiences and connects new industries.
• Like its predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell. 
  • First generation – 1G
    1980s: 1G delivered analog voice.
  • Second generation – 2G
    Early 1990s: 2G introduced digital voice (e.g. CDMA- Code Division Multiple Access).
  • Third generation – 3G
    Early 2000s: 3G brought mobile data (e.g. CDMA2000).
  • Fourth generation – 4G LTE
    2010s: 4G LTE ushered in the era of mobile broadband.
• 1G, 2G, 3G, and 4G all led to 5G, which is designed to provide more connectivity than was ever available before.
• 5G is already here today, and global operators started launching new 5G networks in early 2019. In 2020, many countries expect nationwide 5G mobile networks. Also, all major Android phone manufacturers are commercializing 5G phones. And soon, even more people may be able to access 5G.
• 5G has been deployed in 35+ countries and counting.

Explanation:

• VoLTE is voice calls over a 4G LTE network, rather than the 2G or 3G connections. VolTE can transmit data too. VoLTE has up to three times more voice and data capacity than 3G UMTS and up to six times more than 2G GSM. So, both 1 and 2 are wrong.
