Gigabit 4G LTE Technology 8T8R Beamforming

What is Circuit Switched FallBack (CSFB) ? Circuit Switched FallBack (CSFB) is a technology used in 4G LTE whereby voice and SMS services are delivered to LTE devices through the use of GSM or another circuit-switched network. Circuit Switched FallBack is needed in some networks because LTE is a packet-based all-IP network that cannot support […]

Gigabit 4G LTE Technology 8T8R Beamforming

4G LTE Cells, Sectors and Antenna Beamforming Why Beamforming in Cellular Radio Design? In cellular radio network design, a simple hexagon is used to represent a complex object: the geographical area covered by cellular radio antennas. These areas are called “cells.” This shape lets us picture the cellular idea on a map, because when displaying […]

5G Network Speed

How fast will 5G be?  Examining how fast the promised speeds for 5G: Currently -at time of writing, October 2018:  The 5G standards are not yet finalised by the 3GPP and the most advanced services are still in the pre-commercial phase. In fact, we probably won’t see any commercial 5G services before at least 2020, so […]

ITU Regions

What are ITU Regions? The International Telecommunication Union (ITU), in its International Radio Regulations, divides the world into three ITU regions for the purposes of managing the global radio spectrum. Each region has its own set of frequency allocations, the main reason for defining the regions.  These regions are used to define the frequency bands […]
