5G Networks Proposed for 2020 (estimate)

7 Sep 2015


1G started + 1980 – used analogue; wireless networks became digital in 2001.  3G was born in 2010 and later 4G providing mobile devices with broadband access.  4G is based on standards called Long Term Evaluation (LTE).

Wireless devices currently operate in the crowded 700 MHz to 2.6 GHz radio frequency compass.  This is known as Very High Frequency (VHF).

5G will operate in bands between 3GHz to 30 GHz Super High Frequency (SHF) or from 30 GHz to 300 GHz Extra High Frequency (EHF).

Mobile phone companies are currently discussing what to include in 5G – other heavy weights  such as Google and Facebook are likely to have their influence.  Instantaneous connectivity will be a given.  Latency is the term for response time – the speed at which two devices can communicate with each other.  4G speed is 50 milliseconds; the data rate of 5G is likely to be an average speed of 1 Gbps increasing to 10 Gbps.

All this tells us that mobile technology is not about plateaus – be prepared.  Report from “Economist” ed May 30th to June 5th 2015.
