mmwave 18 A chance to watch.  Press releases sometimes are as credible as politician's speeches, so I'm looking forward to watching Tuesday's live demo of a 5G network. At the Texas Wireless Summit, Arunabha Ghosh of AT&T will present Designing Ultra-Dense Networks for 5G at 9:40. At 10 a.m., AT&T will demonstrate their state of the art 5G testing. This will be one of the first public demonstrations of a 5G mmWave system. Webcast by RCR Wireless.

AT&T & Ericsson are working on phased arrays with ultra-fast beam steering, feedback-based hybrid precoding, multi-user multiple-input/multiple-output, dynamic beam tracking and beam acquisition. Beamforming and related technologies seem may be a breakthrough that extends the reach and throughput of mmWave systems. mmWave Works!, as Ted Rappaport proclaimed a few years ago. The question now is where it will prove financially practical. All those small cells and backhaul can be very expensive.

 The day will mostly be devoted to connecting and automating cars, with top speakers. Robert Heath of the University of Texas is one of the organizers; he co-wrote the book on millimeter wave and is working to solve some of the remaining problems. 


dave askJuly 2017 Gigabit LTE is real in 2017. So is 5G Massive MIMO. 5G mmWave to fixed antennas is likely 2018, with mobile to follow. China, Japan, Korea, and Verizon U.S. have planned $500B for "5G," with heavy investment expected 2019-2021. 

Being a reporter is a great job for a geek. I'm not an engineer but I've learned from some of the best, including the primary inventors of DSL, cable modems, MIMO, Massive MIMO, and now 5G mmWave. Since 1999, I've done my best to get closer to the truth about broadband.
