The Wireless Revolution: Cellular Systems and Networks

GSM = Better roaming international CDMA = Doesn't use SIM cards 3G Networks = Offer higher transmission speeds 4G Networks = Entirely packet-switched

GSM = Widely used globally CDMA = Common in certain regions 3G Networks = Enabling video, graphics, and broadband Internet access 4G Networks = Voice, data, and high-quality streaming video

GSM = Time Division Multiple Access (TDMA) CDMA = Code Division Multiple Access 3G Networks = Higher transmission speeds 4G Networks = Speeds up to 100 Mbps
