CPRI and eCPRI Interfaces for 4G

Posted on

What Are CPRI and eCPRI? CPRI, or Common Public Radio Interface, defines key interface specification between REC (Radio Equipment Control) and RE (Radio Equipment) of radio base stations used for cellular wireless networks. It is a protocol of choice for fronthaul communications between towers and base stations (BSs) through several generations of wireless networks. CPRI […]

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 […]

Gigabit 4G LTE Technology 8T8R Beamforming

Beamforming and 8T8R LTE Radios New technologies, new techniques One of the early lessons learned by operators deploying LTE TDD was that of implementing beamforming with 8T8R (8 transmit, 8 receive) radio modules from the beginning. China Mobile is utilizing beamforming with 8T8R within the majority of its base stations from day one, a consequence […]

Voice over LTE (VoLTE)

What is VoLTE? VoLTE stands for voice over LTE and it’s more or less exactly what it says on the tin. It’s voice calls over a 4G LTE network, rather than the 2G or 3G connections which are usually used. We tend to think of 4G as mostly being about downloading, streaming and web browsing, and indeed that’s […]

ITU Regions for 4G, 5G, LTE

Posted on
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 […]
