5G mmWave Spectrum New Radio (NR) is the wireless standard and foundation for the 5th generation of mobile networks.Its development is part of continuous mobile broadband evolution process to meet the requirements of 5G as outlined by IMT-2020. NR aims to make wireless broadband same as of wireline with the fiber-like performance at a significantly lower … Read more
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 we want to introduce an android App which can be used to calculated 5G NR-ARFCN and 4G LTE EARFCN for … Read more
5G Cell Phone Architecture 5G cell phones has to be designed to comply either 3GPP New Radio (NR) Release 15 and also need to support legacy radio access technologies . Intial, 5G cell phones will be support Non-Stand Alone (NSA) protocol stack. Requirements for 5G Cell Phone Comply to 3GPP Release 15 – NSA Support … Read more
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 is required for downlink and another for uplink as downlink and uplink frequencies are different while for TDD system … Read more
Recently, 3GPP has freezes specification for 5G NR and TS 38.104 section 5.2 provides the list of bands in which NR (New Radio) can operate. As per 3GPP release 15 , these frequency bands are desingated for different frequency ranges (FR) and current specification (Release) defines them as FR1 and FR2. Below table shows the … Read more

5G Technology Key Performance Indicators (KPIs) 3GPP is still in process of finishing out 5G/NR Key Performance Indicators (KPIs). These KPIs are driven from ITM-2020 and some of these are listed below. These KPIs mainly consider three broad categories: Enhanced Mobile Broadband (eMBB) Mission Critical Control (MCC) Massive Internet of Things (Massive IoT) Parameter Key Performance … Read more
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 symbol. Subcarrier Spacing In 5G NR, subcarrier spacing of 15, 30, 60, 120 and 240 … Read more
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 FFT size. Considering above equation timing can be calculated as follows: Tc = 1 / (480 x 103 x 4096) = 1 … Read more
