Sometimes you just stumble into new discoveries. This morning I came across this video about 5G. I learned about the evolution of mobile networks and how the 5G network will enhance our lives.
Breakdown of the Video Timeline
(00:18) Introduction to the Video
(00:22) Quick History of Mobile Networks
- (00:31) 0G: Mid-1940's car phones;
- (00:58) 1G: 1981, first generation personal mobile phones;
- (01:16) 2G: 1992, digital standards for text messaging;
- (01:41) 3G: 2001, multimedia integrating video, data, and voice;
- (02:13) 4G: 2011, faster speeds;
LTE is an acronym for Long-Term Evolution

(02:55) Core Technologies and Stats
(03:14) Millimeter Waves (mmWaves)
- (03:44) Exponential growth in interconnected devices
Snapshot from video
- (04:00) mmWaves open up the spectrum;
Snapshot from video
- (04:20) Shared spectrum for mission critical functions (controlled (self-driving) vehicles, remote surgeries, industrial processes);
(05:15) Massive Multiple Input Multiple Output (MIMO)
(05:17) High data rates, increased capacity for multiple users, better cell-edge and indoor use experience;
(05:37) 256 element antenna array;
(06:05) Alble to provide connectivity to 1,000,000 devices per sq. kilometer;
(06:30) Massive MIMO beamforming;
(06:38) 3D Beamforming
- (07:33) Qualcomm Research 5G mmWave Prototype -- demonstrating sustained and robust mobile broadband;
(08:46) Small Cells
(10:00) Full Duplex Radio Integrated Circuits
(11:02) Speed -- 5G speed over 10 Gbps;
(11:30) Latency -- time between action and instruction -- 5G reduces latency down to 1 millisecond;
(12:02) Nokia demonstration of reduce latency -- 4G versus 5G faceoff;
(13:17) Bandwidth -- 5G enables 1 million devices per sq. kilometer;
(13:37) Energy Consumption -- 5G enables longer battery life of devices -- 5G requires 90% less energy than 4G;
(14:20) Transition from 4G to 5G
(14:45) 4G Lte (Longer Term Evolution) and 5G NR (New Radio)
(15:16) 4G Lte-A (Longer Term Evolution - Advanced)
(15:23) Why 4G Speeds Are Slow
(15:44) 3G and 4G networks supporting more devices than anticipated;
(16:06) 4G Lte Advanced Pro -- Propel mobile broadband, Proliferate LTE connectivity, Progress towards 5G;
(17:40) Timeplan -- 2018, 2019, 2020;
(18:06) Nokia presentation and insight into the complexity of carrier aggregation;
(19:12) Rollout of 5G in year 2020+
(20:00) Deceptive Advertising
