Our Future With 5G In Central Florida!
Dear Friends & Neighbors,
5G Future (presented at: WindermereSun.com)
(Please click on red links & note magenta)
It was recently (September 11, 2018) announced that Orlando and Jacksonville will be among the 19 cities (Las Vegas, Los Angeles, Nashville, Orlando, San Diego, San Francisco, San Jose, San Antonio, New Orleans, Houston, Jacksonville, Louisville, Dallas, Atlanta, Waco, Charlotte, Raleigh, and Oklahoma City) to debut AT&T’s new standards-based mobile 5G technology in early 2019. Across its 19 5G deployments, AT&T had selected Ericsson, Nokia, and Samsung as its vendors.
When AT&T announced the first three cities to get mobile 5G, in the video below:
Let’s see what wikipedia has to say about 5G, in italics, below:
5G is the fifth generation of cellular mobile communications. It succeeds the 4G (LTE/WiMax), 3G (UMTS) and 2G (GSM) systems. 5G performance targets include high data rate, reduced latency, energy saving, cost reduction, higher system capacity and massive device connectivity. The first phase of 5G specifications in Release-15 will be completed by March 2019, to accommodate early commercial deployment. The second phase in Release-16 will be completed by March 2020, for submission to the ITU as a candidate IMT-2020 technology. [1]
The ITU IMT-2020 standard provides for speeds up to 20 gigabits per second and has only been demonstrated with millimeter waves of 15 gigahertz and higher frequency. The more recent 3GPP standard includes any network using the NR New Radio software. 5G New Radio can include lower frequencies, from 600 MHz to 6 GHz. However, the speeds in these lower frequencies are only modestly higher than new 4G systems, estimated at 15% to 50% faster.[2]
5G NR speed in sub-6 GHz bands can be modestly higher than 4G with a similar amount of spectrum and antennas.[3][4] Adding LAA (Licensed Assisted Access) to a 4G configuration can add hundreds of megabits per second to the speed.[5]
Until there is substantial field testing, 5G speeds can only be estimated. Qualcomm, the leading chipmaker, presented at Mobile World Congress a model that has been cited by many.[6][7][8] The simulation predicts 490 Mbit/s median speeds for a common configuration of 3.5 GHz 5G Massive MIMO. It predicts a 1.4 Gbit/s median speed for a configuration using 28 GHz millimeter waves.[9]
Some 3GPP 5G networks will be slower than some advanced 4G networks. T-Mobile’s LTE/LAA network is deployed and serving customers at over 500 megabits per second in Manhattan.[5] The 5G specification allows LAA as well but it has not yet been demonstrated.
With increased ability to collect data at a faster rate, our cities will be smarter and our world will be smarter.
