Hua Zhou, Wireless Technology Specialist at Ofinno, recently wrote a whitepaper which presents an overview of some 3GPP Rel-17 features enhancing efficiency and performance of 5G NR Rel-15/16, addressing the needs of vertical industries and supporting satellites and HAPs. There are many other features targeting different performance metrics (such as latency reduction and quality of … Read more

During a recent Lunch & Learn, Weihua Qiao presented on the topic of “Smart Railway Stations.”  A Smart Railway Station uses different types of electronic Internet of Things (IoT) sensors to collect data to improve efficiency, mobility and sustainability.  The premise of this concept is to create a barrier and stress free experience for every … Read more

In the modern lexicon, pilotless aircraft are known as “drones”. In English, the term has long referred to male honeybees. Unlike worker bees, who gather nectar and pollen, a drone’s only function is to mate with an unfertilized queen bee. According to military historian Steven Zaloga, the term has been applied to pilotless aircraft since … Read more

Cellular communications have made major technological advancements to keep up with developments in other fields such as automation, multimedia, and sensor management. These technological developments can be repurposed to support ISR purposes. In particular, the 5G terrestrial infrastructure can provide a national radar tracking network. download the article

Advancements in battery technology continues to be slow compared to increasing data rate and bandwidth demands of fifth generation (5G) cellular technology such that battery life could become a bottleneck for 5G. Power saving techniques are therefore vital to the success of 5G. This article gives a brief introduction to many of these power savings … Read more

Coexistence of Wi-Fi and LTE-Unlicensed (LTE-U) technologies has drawn significant concern in industry. In this paper, we investigate the Wi-Fi performance in the presence of duty cycle based LTE-U transmission on the same channel. More specifically, one LTE-U cell and one Wi-Fi basic service set (BSS) coexist by allowing LTE-U devices to transmit their signals … Read more

Overview New radio (NR) is a study item in the 3rd Generation Partnership Project Radio Access network Working Group (3GPP RAN-WG) focusing on a new Radio Access Technology (RAT) for the 5th Generation (5G) cellular communications systems. Together with the next generation core network (NextGen Core), NR fulfills requirements set forth by the International Telecommunication … Read more

In mission critical situations, communications among responders must maintain a high level of reliability, availability, quality of service and security in scenarios that go beyond the limits that are stipulated in a commercial wireless network. The 3rd Generation Partnership Project (3GPP) Technical Specification Group on Service and System Aspects (TSG-SA) has developed a series of … Read more

Herndon, VA – Fifth generation (5G) wireless networks are expected to support massive connectivity, high capacity, ultra-reliability and low latency. Such diverse use case scenarios require disrupting approaches for the realization of future 5G systems. It is envisioned that multiple transmission and reception points (multi-TRPs) will be vital in 5G in order to improve reliability, coverage, … Read more
