HD Map (EdgeMap) Crowdsources Data From Connected Vehicles in Auto Edge Computing


New research paper from University of Nebraska-Lincoln, Xidian University and University of North Carolina at Charlotte. Abstract "High definition (HD) map needs to be updated frequently to capture road changes, which is constrained by limited specialized collection vehicles. To maintain an up-to-date map, we explore crowdsourcing data from connected vehicles. Updating the map collaborati... » read more

Open RAN Direct RF Sampling Radio Transceiver Architectures For Massive MIMO


With the exponential increase in wireless traffic, mobile networks are transformed into more software-driven, virtualized, flexible, intelligent, and energy efficient systems. These trends have stimulated significant change in the core network with the advent of software defined networks (SDN) and network functions virtualization (NFV), which have enabled building more agile and less expensive ... » read more

Security Risks Grow With 5G


5G mobile phones can download a movie in seconds rather than minutes, but whether that can be done securely remains to be seen. What is clear from technology providers, though, is they are taking security very seriously with this new wireless technology. More data is in motion, and the value of that data is growing as users rely on mobile devices for everything from banking to automotive saf... » read more

Power Amp Wars Begin For 5G


Demand is increasing for power amplifier chips and other RF devices for 5G base stations, setting the stage for a showdown among different companies and technologies. The power amplifier device is a key component that boosts the RF power signals in base stations. It's based on two competitive technologies, silicon-based LDMOS or RF gallium nitride (GaN). GaN, a III-V technology, outperforms ... » read more

Carriers Push Datacenter-Style Virtualization


The world’s largest telco carriers are leading a broad movement to bring data center-style virtualization to the core of their telecommunications networks. In an industry known for being extremely conservative when it comes to change, this one appears to be significant. The move has set off a scramble among a number of companies for unified control and forwarding plane designs, starting fr... » read more
