LTE eNodeB Scheduler and Different Scheduler Type
What is a LTE Scheduler ? Scheduling is a process through which eNodeB decides which UEs should be given resources (RBs), how much resource (RBs) should be given to send […]
KPI Requirements for Next Generation Access Technologies
A fully mobile and connected society is expected in the near future, which will be characterized by a tremendous amount of growth in connectivity, traffic volume and a much broader […]
Narrow Band (NB) -IoT Modem Chip Vendors
There are a number of wireless technologies available for the Internet of things. These are mainly divided into two categories: Short Range (Zigbee, WiFi, Bluetooth, Z wave) Long Range (LoRa,SigFox, […]
Spectral Efficiency : 5G-NR and 4G-LTE
What do you think of when you hear word “spectral efficiency?” The answer will come, it has to do with the amount of information that fits in a given channel […]
5G/4G ARFCN Calculator Android App
Few weeks back, we wrote a post about 5G New Radio ARFCN calculator. Below is the link for the same. 5G Absolute Radio Frequency Channel Number (NR-ARFCN) In this post […]
3GPP Release-15 UE Cat Types, Throughput, Modulation and Supported UE DL / UL Combinations
UE Category information is used to allow the eNB to communicate effectively with all the UEs connected to it. The ue-Category defines a combined uplink performance capability and downlink performance capability. […]
5G Absolute Radio Frequency Channel Number (NR-ARFCN)
An Absolute Radio-Frequency Channel Number (ARFCN) is a code that specifies the a pair of reference frequencies used for transmission and reception in radio system. In a FDD system one ARFCN number […]
5G New Radio Throughput Calculation
The DL and UL max data rate supported by the UE is calculated by band combinations and baseband processing combinations supported by the UE. For NR, the approximate data rate […]
5G NR- Physical Layer Timing Unit
In 5 G New Radio the basic time unit is represented by Tc and as per 3GPP TS38.211 can be expression by following equation: Where is subcarrier spacing and is […]
5G NR Terminologies – Subcarrier Spacing, Fram-Subframe, Slot and Symbol
This post covers 5G Subcarrier spacing as compare to LTE, 5G Frame and Subframe, possibilities of different type of 5G NR slot depending upon the different subcarrier spacing and OFDM […]
