5G NR: An Overview

  Add to Google Calendar
Date:  Wed, June 19, 2019
Time:   6:30pm - 8:00pm
Location:  Holmes Hall 244
Speaker:  John Imperial, IEEE Hawaii Section Vice-Chair, and Joint Signal Processing and Communications Hawaii Section Chapter Chair

5G has been the in the news, both at the technical/professional level and everyday media.

As a practitioner, Mr. Imperial will not focus on theoretical research or processes, but on the specific effects that impact actual implementation and everyday end-user experience.

5G has been confused with 5 GHz WiFi. All Radiofrequency (RF) technologies are governed by fundamental RF concepts.

Mr. Imperial’s presentation will begin with fundamental RF Concepts; a comparison 5G vs 5G E vs 5GHz; a broad overview to highlight issues related to 5G; different 5G Market Areas; 5G Frequency Bands; Comparison of WiFi vs Cellular Architecture; 4G/4G LTE/5G NR Architecture; 5G NR Radio Access Network Architecture; and Toolsets and Real-World Measurements.

Mr. Imperial will focus on the Radio Access Network (RAN) for 5G NR since this will differ based on the targeted User Equipment (UE) device.
