5G All you need to know!

5G, or 5th generation mobile, is the next big leap in wireless communications. You’ve probably heard about it in commercials or seen it in headlines. But much of the discussion about the new technology has been focused on its engineering features, infrastructure requirements and public policy considerations. With technical buzzwords like “network slicing,” “beamforming,” and “multi-access edge computing,” it may be hard to really understand what 5G is all about and why we should care.

Here, then, is a brief explanation of how 5G will be used and what it will mean for your online experience — why you maybe should care!

Supplement rather than Replace

5G, which will supplement rather than replace today’s 4G networks, will radically improve the bandwidth, capacity and reliability of mobile broadband.

How?

In part by packing thousands of small antennae onto cell towers, utility poles and buildings, 5G will push mobile speeds from 100 Mbps to upward of 10 Gbps, a thousandfold increase that will make next- generation wireless competitive with even the fastest fiber- optic wired networks.With all that new capacity, expect to be watching even more high-definition video on your smartphone or tablet, including ultra- high- definition movies and emerging technologies such as augmented- and virtual- reality applications (think of Pokémon Go as a prototype).

The benefits to come

But the real excitement over 5G comes with new uses that simply aren’t possible with today’s networks. Many of these involve the revolution in sensors, low- cost transmitters and cloud-based software known as the Internet of Things ( IoT), or “connected” or “smart” devices.

Right now, IoT products include stand-alone devices such as fitness monitors, smart thermostats, programmable door locks and lightbulbs, connected appliances, and other gadgets. But as billions more things go online over the next several years, they will be using 5G networks to send and receive massive amounts of new data.

For example in 4G, you will wait for 6mins for your 2 hour movie to load online, but with 5G it will only take 3 and half seconds for the whole movie to load. It will not only be the internet speed that improves but also the response time. The 4G network responds to commands under 15 milliseconds while the 5G is expected to respond in 1 millisecond and that is 400 times faster than a blink of an eye!

Further if we get a bit more technical,

At the human level, for example, 5G will be used for connecting smart clothing, prosthetic devices and even ingestible health monitors. Consider a start-upVeryshoestride, which has been working since 2012 on smart shoe technology. That might sound silly, but not to the millions of people with temporary or permanent mobility issues, for whom constant feedback from onboard sensors could help teach them to walk again after a stroke or surgery.

At home, 5G networks will move beyond the cliche of refrigerators that automatically reorder milk to fully integrated living spaces that adjust to the needs of every member of the family, providing home security, optimizing power and water usage, and personalizing entertainment. Smart homes will be much more energy- efficient. But more important for an aging population, 5G networks will help seniors to age in place, monitoring their medications, connecting them to telehealth services and tracking indicators from sleep to insulin levels.

Rural users will benefit as well, as 5G enables smart agriculture, communicating with sensors in the ground, in crops, and on livestock and farm machinery. Along with weather satellites and drones, these technologies will help farmers know when and how much to water, fertilize and apply pesticides in more effective and environmentally friendly ways. Smart farming may

also drive the case for deploying 5G networks to rural areas more rapidly, closing what remains of the digital divide as a happy side effect. This is all not possible for our country but let’s just say there’s hope for everything one day!

In cities and across national borders, finally, 5G’s ultralow transmission delay (or “latency”) will be crucial for autonomous vehicles, smart energy grids and connected infrastructure. These will not only improve the quality of government and utility services but also enhance public safety, health and sustainability. Already, smart-city technology in such places as Barcelona, Singapore and Columbus, Ohio, is being used for instant crime reporting, smart streetlights, and sensors that monitor things like air quality, parking spaces and garbage collection.

The benefits of 5G to a country like Sri Lanka is quite questionable as our systems of transport, crime reporting, and health are not in the standard all over the world. We battle things way worse than first world problems, but rather than battling those out we also tend to make a mess out of things.

With the potential to remake and revitalize local industries in the U. S, including education, health care, manufacturing, energy, entertainment and agriculture, it’s no surprise that network operators, equipment providers and forwardthinking policymakers are fully engaged in the coming 5G revolution.

Wall Street, on the other hand, is skeptical. It’s estimated that deploying 5G technology will cost upward of $ 200 billion a year for the next five to 10 years in the United States alone — nearly all of it coming from private investors. Until it’s more widely understood how much and to whom the benefits of 5G applications will flow, build- out may not proceed fast enough to compete with other early- adopting countries, notably China.

However knowledge is treasure, so having 5G will improve communication and bridge the lag of many needed services. There’s many uses of 5G other than better and speedier smartphones, but of course we will buy ourselves new phones which support 5G and continue watching Netflix or browsing Facebook for all that’s worth!
