What is 5G you ask ?
5G simply means the fifth generation of mobile internet speed that is the newest and next mobile wireless technology which is built on IEEE 802.11ac, even though a formal benchmark is yet to be set. 5G network is a user eccentric, lightning fast and is a true successor to 4G LTE (Long Term Evolution).
5G network will be altogether speedier than 4G, taking into consideration higher profitability over every smart device with a claimed download speed of 10,000 Mbps. In addition, with more noteworthy data transfer capacity comes faster download speeds and the capacity to better web applications.
How fast is it ?
Lets say you want to download a 2 hour movie:
Under 3g it would have taken more the 26 hours or take a flight around the globe.
Under 4g it would have taken 6 minutes or the time it took you to check your facebook feed.
Under 5g it would have taken 4 seconds or the time it took you to to say is it downloaded yet ?
When can you get it ?
While all of the carriers are testing out potential 5G technologies right now, it’s not expected that actual 5G networks will launch until around 2020 or thereabouts. The final specifications for 5G networks are expected to be ratified by mid-2018, at which point implementation testing and network building can commence.
It’s also worth keeping in mind that some overseas networks may well launch what they call “5G” networks in advance of the specifications being finalized. That’s more likely to be a matter of branding and providing patching to existing networks than a “true” 5G network to speak of, depending on how those standards roll out.
The higher frequencies expected to be a large part of the 5G story do present a challenge to telcos, because those higher frequencies typically travel shorter distances than lower frequencies. As such, mixing and matching technologies and frequencies is going to be key for telcos, as well as the use of technologies such as MIMO (Multiple Input Multiple Output) antennas. These use additional antennas to allow for wider boosting of 5G signals, as well as enabling MIMO-compliant devices to access the best possible speeds even in areas where signal may otherwise be poor.
It’s expected that the first consumer 5G devices will be effective dual 4G/5G devices simultaneously in order to maintain network connectivity at all times, but it’s still way too early to theorise about what those devices will be.
