Fast internet connectivity is what everybody wants, especially at this time where gadgets and smart phones are pretty much a necessity in every household. This is why almost all major telecoms companies around the world are doing everything they can to improve the speed of internet connections. 5G, a totally new shape of wireless signal, is now needed to emit enough bandwidth for the wireless feed. The road to 5G actually began in earnest back in 2012, although China’s Huawei and ZTE both (separately) began working on the technology in 2009.
What specifically is 5G? It is the newest form of wireless connection specially made to go along with the increasing number of gadgets that requires internet connectivity. Aside from phones and computers, there are other home appliances, door security, CCTV, and cars that are now dependent on the web and so an improvised and enhanced kind of Wi-Fi connection is very much in demand.
“G” stands for “generation” in 5G. It is the better and faster version of 4G LTE, with an evident difference. Through 5G, people can still send text messages, phone calls, and browse the web, but it significantly speeds up data transfer across the network. As a result, downloading and uploading Ultra HD and 3D video will be much easier with a 5G connection.
5G works by converting your voice into an electrical signal once you make a phone call just like a mobile phone being a two-way radio. The electrical signal is then sent out to the nearest cell tower through radio waves then the cell tower bounces the radio wave by a network of cell towers then to the receiver’s phone. Same action takes place when you send other data such as photos and videos to the network or post them on social media.
Once a new form of mobile wireless technology becomes available like 5G, it gets assigned to a higher radio frequency. The reason behind this is because higher frequencies aren’t in use, resulting to fast information dissemination. The only loophole with this setup is that higher frequency signals don’t travel as far as lower frequencies, so several input and output antennas might be used to boost the signals where 5G is available.
Where are we now with 5G? The first 5G wireless channel models have already been published. A group of eight partners of the METIS Task Force accomplished the work and launched the first temporary 5G channel models formally accepted by the METIS community. This is an integrated project under the European Union Seventh Framework Program for study and improvement and also a chief large-scale global research activity on 5G. These published interim models were initially presented to the 5G technical community at the Brooklyn 5G Summit. The actual copies of the models are available on the METIS website.
There is already a reported 5Gbps speed in a 5G live test network that was reported by Ericsson. This test was done through the use of a modern radio interface concept along with highly developed MIMO (Multiple-Input Multiple-Output) technology with more extensive bandwidths, higher frequencies and faster transmission gaps. Talking about frequency, the 5G network consumed a 15 Ghz frequency band, which is higher and shorter range compared to 3G or 4G cellular frequencies.
Despite the current tests being done with 5G, most experts predict that it won’t be commonly available until 2020. We presume 5G will be worth the wait.
