Broadband Wireless consists of many areas including WiFi, WiMAX, and broadband cellular technologies.
Fourth Generation (4G) cellular, manifest in the Long term evolution (LTE) stadard, is a major step forward in cellular 3G services. LTE technology is a based on a 3GPP standard that provides for a down-link speed of up to 150 Mbps and an up-link speed of up to 50 Mbps. Fixed wireless and wired standards are already approaching or achieving 100 Mbps or faster, and LTE is a way for cellular communications to operate at that high data rate.
Fifth Generation (5G) cellular represents the latest stage in the evolution of mobile communications. It is also a new standard that relies upon various supporting technologies including millimeter wave propagation, IPv6 transmission protocol, and many others including some that are still in the R&D stage with major infrastructure providers. Among other major differences as compared to the fourth generation of cellular, 5G network demands higher data rate in a range of several gigabits per seconds (Gbps) and this can achieved using steerable antennas with Millimeter Wave (mmWave) technologies.
