5G

History

5G is a not-yet-implemented wireless technology that's intended to improve on 4G.

        5G promises significantly faster data rates, higher connection density, much lower latency, among other improvements. 5G is the next generation of mobile networking technology following 4G. Much like every generation before it, 5G aims to make mobile communication faster and more reliable as more and more devices go online. 

           

          As billions more devices connect to the web, the entire infrastructure needs to accommodate the traffic to not only support faster connections but also better handle simultaneous connections and provide broader coverage for these devices. This is what 5G is all about.

How Is 5G Different Than The Other "Gs"?

5G is simply the next numbered generation following 4G, which replaced all of the older technologies.

• 1G introduced analog voice

• 2G introduced digital voice

• 3G ushered in mobile data

• 4G paved the way for widespread mobile internet usage

Speed

5G NR speed in sub-6 GHz bands can be modestly higher than 4G with a similar amount of spectrum and antennas.Adding LAA (Licensed Assisted Access) to a 4G configuration can add hundreds of megabits per second to the speed.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.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.
  
        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.The 5G specification allows LAA as well but it has not yet been demonstrated.

5G Will Integrate LTE

5G will likely be designed to build upon the existing LTE networks and many features will start to be available as part of the LTE-Advanced Pro standard.

          Some of those features include carrier aggregation, which lets operators use existing spectrum more efficiently and also increases network capacity. Carrier aggregation will also allow wireless operators to increase user throughput rates.
