The 5G network promises to transform industries and our digital society by providing enhanced capacity, higher data rates, increased battery life for machine-type devices, higher availability and reduced power consumptions. In a way, 5G will act as a vehicle to drive much needed digital transformation race and will push the world into the information age. Also, 5G can be used to replace the existing emergency communication network infrastructures. Many countries are about to launch 5G services commercially as 5G standards have been developed by the 3GPP group, including security procedures. The following map in Figure 1 shows 5G deployments worldwide.
