Citizens Broadband Radio Service Device (CBSD) for 4G: CBSD devices using CBRS (Citizens Broadband Radio Service) is defined in the USA for Shared Spectrum Access in 4G Band 48 (5G Band n48) in the 3.5GHz spectrum, 3550 MHz to 3700 MHz. CBRS can be implemented using 4G, 5G or proprietary technology wireless systems What is […]
CDR (Call Detail Record) is used for billing of voice calls in 4G/5G/LTE systems What is CDR? CDR refers to the call detail record provided by a telecom service provider. It is data containing information about system usage, documenting the details of calls or other communication transactions.It contains multiple call attributes such as identities of source and destination, […]
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 […]
RadioMobile: Popular software for 4G Network planning RadioMobile is a widely-available software package which can be used for 4G Network planning, including path profiling and clearance criteria, power budgets, choosing antenna sizes and tower heights. For website for RadioMobile, please see this link here: RadioMobile functions For 4G Network Planning, the software package can be […]
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 […]
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 […]
Introducing Massive MIMO Technology Massive MIMO will play a key part in the 5G networks of the future. Several mobile network operators around the world have already begun rolling the technology out. Massive MIMO is important to 5G Networks Explaining Massive MIMO MIMO stands for Multiple-input multiple-output. While it involves multiple technologies, MIMO can […]
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 […]
MMW: Millimeter Wave essential to meeting spectrum crunch and data demand Gigabit LTE is boosting capacity to meet demand today and setting the stage for a smooth roll out of 5G that will enable users to have a consistent network experience as they move from 5G hot spots onto gigabit LTE. But there’s a big […]
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 […]
