Field Testing In 5G NR


5G NR network coverage measurements will be beam-based instead of cell-based. This will change the methodology of coverage KPI calculation. The amount of reference signals in the air is increasing as there will be multiple reference beams per cell, posing more stringent performance requirements for scanning receivers and test UEs. Both test UEs and scanners will be needed for 5G NR field verifi... » read more

Optimize 5G New Radio MIMO Test And Debug


Radio technology is evolving from single antenna transmit-receive communication systems to multiple-input multiple-output (MIMO) antenna communication systems. MIMO technology is a wireless communication technique for sending and receiving multiple data signals simultaneously over the same radio channel. MIMO techniques play a prominent role in Wi-Fi communications, as well as in 4G long-term e... » read more

The Great Migration To 5G Is Underway


Every decade brings with it a plethora of technology changes, and the cumulative effects of 50+ years of changes in wireless technologies are noteworthy for how they have changed the way we communicate. The 80’s began the era of personal computing along with 1G rollout The 90’s saw the advent of 64-bit microprocessor architecture in consumer devices coinciding with 2G rollout The... » read more

New technical paper from Georgia Tech. Abstract "This work presents a novel tile based approach to constructing, in a modular fashion, massively scalable MIMO and phased arrays for 5G/B5G millimeter-wave smart skins and large-area reconfigurable intelligent surfaces for Smart Cities and IoT applications. A proof-of-concept 29 GHz 32 elements phased array utilizing 2×2 “8-element subarr... » read more

Increasing Performance With Data Acceleration


Increasing demand for functions that require a relatively high level of acceleration per unit of data is providing a foothold for in-line accelerator cards, which could mean new opportunities for some vendors and a potential threat for others. For years, either CPUs, or CPUs with FPGA accelerators, met most market needs. But the rapid increase in the volume of data everywhere, coupled with t... » read more

A compact two elements MIMO antenna for 5G communication


Abstract: "This study presents a simple, miniaturized, and low-profile multiple-input multiple-output (MIMO) antenna operating at 29 GHz with reduced mutual coupling between the antenna elements for futuristic 5G communication. The proposed design employs two radiating elements with slits in the radiators to produce high isolation among the antenna radiators. The MIMO antenna maintains a compa... » read more

Accelerating 5G Baseband With Adaptive SoCs: Part II


In my previous blog, we discussed 5G split architectures with focus on the widely adopted option 7-2 split. In this article, we will cover the implementation of the fronthaul and L1 Hi-PHY for 5G base stations. The 5G distributed unit (DU) can be implemented to process fronthaul data with O-RAN processing and partial offload for Hi-PHY processing which includes the LDPC encoder, LDPC decoder an... » read more

The Search For 5G mmWave Filters


Cellular telephone technology takes advantage of a large number of frequency bands to provide ever-increasing bandwidth for mobile use. Each of those bands needs a filter to keep its signals separate from other bands, but the filter technologies in current use for cellphones may not scale up to the full millimeter-wave (mmWave) range planned for 5G. “MmWave will happen,” said Mike Eddy, ... » read more

Accelerating 5G Baseband With Adaptive SoCs


5G new radio (NR) network specifications demand new architectures for radio and access networks. While the 5G NR architecture includes new spectrum and massive MIMO (mMIMO) antennas, corresponding access networks architecture must also evolve to implement the services defined by 5G, which include enhanced Mobile Broadband, Ultra Reliable Low Latency Communications and massive Machine Type Commu... » read more
