* Rollout: 2019 - 2020

* Frequency Range: 30-300 GHz (Early versions possibly 100 MHz - 6 GHz. Current WiFi uses 2 GHz - 6 GHz)

Radio Frequencies explained:

* Speeds: 100 Mbps to 20 Gbps

* Numerous small antennas

* 1st Phones: Samsung 1st 1/2 of 2019, Apple 2020

* 60-120 times lower latency, usually < 1 millisecond

* Peak speed ~ 20 x 4G speeds

* Faster for non-mobile connections than mobile connections

* Uses:

  • Smart cities
  • Smart grids
  • Smart home devices
  • Vehicle-to-vehicle communications
  • Traffic signal status & control
  • Wearable tech
  • "Internet Of Things" {IoT}
  • Remote connected sensors such as air quality, weather, pressure, open parking spaces, & way more.
  • "Tele-medicine" applications

* Security concerns because of how many devices will be networked and super-fast speeds at which cyber-attacks will be able to propagate.

• ITU ( https://en.wikipedia.org/wiki/ITU ) Standards -15 & -16 will represent Phase I & Phase II rollouts of 5G standards. -15 (Phase I) is due to be finalized in April of 2019. -16 (Phase II) is due for finalization in April of 2020.

• I have not as-yet been able to locate specification standard transmitter power levels for 5G RF transmitters. I suspect that's because the ITU standards are not finalized yet.

• It would appear that mobile carriers are labeling their own proprietary technologies as "5G" in some cases, but that these early "5G" are not necessarily going to be representing "standardized" 5G network technologies. This sounds like a nightmare for governmental regulating entities to monitor and control. AT&T has in the past couple of days (as of 01/08/2019) been a notorious example, simply rolling out a software update to existing 4G phones that changes the network icon to show as 5G-E with NO change in the abilities of their phones or their networks.
