1) The document discusses the evolution of wireless technologies from 1G to 5G. 1G used analog signals for voice calls only, while 2G introduced digital networks and text messaging. 2.5G added basic data services via GPRS. 3G increased speeds and added video calling and mobile internet. 4G provides speeds up to 1Gbps for video and cloud-based services. 5G is expected to offer speeds over 1Gbps and enable new applications with low latency. 2) Mobile networks have both circuit-switched and packet-switched cores. The circuit-switched core handles legacy voice and video calls, while the packet-switched core provides access to data networks. The IMS core
