The new online generation: Explaining 5G internet

Faster, better, and more available?

Published

on

Are you still bothered by slow internet in your country? Even with the advancements and supposed improvements in infrastructure, we’re all living in a 4G world. The current generation of internet connectivity is still present in today’s mobile and telecommunication networks. But now, a new generation has emerged, and it has the potential of taking the whole world by storm.

Let’s stop and ask first: What really is this new generation? How different is it from the existing generation’s internet? And, what needs to be done to welcome the change?

What really is 5G?

5G is the new generation we’re speaking of here. Specifically, it’s the next level of mobile network connectivity being rolled out at the moment. What 5G offers to everyone is pretty straightforward: faster internet speeds, close to zero latency, and improved accessibility. It’s expected that 5G will replace existing 4G technology once fully deployed in the near future.

Currently, 5G is still in its early stages of deployment — much like an early-access game. Companies are given plenty of time to integrate the 5G connectivity interface on their devices, or at least until March 2019. Once the initial deployment is done, 5G will be available in more devices, whether it’s your phone or your smart device.

A connection that comes in waves

Remember that one science class you had about the electromagnetic spectrum and visible light? Basically, devices that emit electromagnetic waves fall under a spectrum depending on their frequencies and wavelengths. For most network connections, their waves follow a similar concept, with 4G found on the leftmost and 5G in the middle.

There are two ways that 5G can work in any place at any time, and one of them includes waves. This strand of 5G is called the millimeter wave (mmWave), and is currently present in most research facilities and military devices. With mmWave, 5G connections are ideally faster (peaking at 10Gbps) and provide lag-free services because it adds additional bandwidth for devices to use. Although, it is held back by obstacles such as walls and floors that just bounce the signal off.

The second way is through a sub-6GHz spectrum. Unlike mmWave, the sub-6GHz spectrum is more of a middle-of-the-pack approach to 5G connectivity. Basically, 5G signals will strengthen connections that currently exist in the world like 3G and 4G. This is mostly because 3G (2.4GHz) and 4G (5GHz) fall under the 6GHz limit. This method is the more cost-effective approach, and it doesn’t easily experience interference.

How different is it really from 4G?

We always talk about how 5G is faster than 4G in terms of data transfer, which is true. But, there are other things that differentiate 5G from its predecessor. For starters, 5G connections can cover a wider area than 4G. This means that even if you’re far from your router or cell tower, you can still access 5G networks at the same speed. Just don’t be too far away, as the technology isn’t capable of reaching that far yet.

Apart from that, 5G is less prone to interference compared to 4G networks. Even if mmWave is hampered with the presence of obstacles, it still doesn’t stop it from performing relatively better than 4G. For example, even if there were several other antennas in your area, you still experience better speeds while on a 5G network compared to 4G. 5G targets devices directly, instead of spreading the waves across the whole area.

Finally, with 5G connections, more devices have access to the network. Currently, 4G networks still have a cap when it comes to the number of devices simultaneously connected. As more devices connect to the same 4G network, internet speeds tend to get slower. With 5G, however, adding more devices won’t hamper its overall performance mostly because of additional bandwidth and wider coverage.

What’s next for the new generation?

Believe it or not: We’re living in the early-access world of 5G. We hear about major telecommunication companies starting to adopt 5G in their mobile networks, and things are about to get bigger. While their data plans are available to the general public, several improvements to network infrastructure are to follow. We’re talking better signal towers, and more of them across the world.

In the future, 5G may not be limited to just mobile networks. Car companies are looking at the possibility of applying 5G to smart cars, especially for navigation. Cars on the road will be able to share data like traffic situation, road hazards, and other delays. Even things like virtual and augmented reality can make use of 5G for better simulations.

By March 2019, the early deployment of 5G will be finished. Hopefully by then, we can get more information on what 5G can do for the world. The new generation is here, but we still have to wait and see how far 5G will take us.

How Google alerted the Philippines during the July earthquake

Crowd-sourcing data

Published

on

Illustrations by Kris Blanco

Back in July, an earthquake rocked Metro Manila. Unbeknownst to most but noticed by some, a globally renowned company was helping everyone through the natural incident: Google. In the few minutes leading up to and during the 6.7 magnitude earthquake, Android users received important alerts warning them of the ongoing tremors. Though it wasn’t the dreaded Big One, the alert afforded attentive users a few precious seconds to either seek appropriate cover or stop doing dangerous tasks.

Incidentally, the tech surrounding Google’s earthquake alert system wasn’t just hastily built on ongoing databases or social media. Google actually packed in a fully responsive earthquake sensor for Android phones.

Faster than an earthquake

The forever-increasing speed of technology has always been a contentious element since the rise of smartphones. Developers and users alike have wondered how accurate or quick our favorite devices can warn us of things happening around us. There’s even an XKCD comic about how Twitter can warn us of an earthquake minutes before it reaches the reader.

Over the years, technology has developed new ways to deliver alerts. From simple weather apps to city-wide messaging systems, users can receive warnings in a timely fashion. Practically nothing is a surprise anymore with the right technology.

That said, Google has successfully developed a new system that can rely on other Android smartphones to accurately tell whether or not an earthquake is happening.

A quake detector in your pocket

Speaking to Android Police, the feature’s lead engineer Marc Stogaitis described how Google’s earthquake sensor leveraged other devices to tell users about the quake. It all revolves around the different sensors built inside your phone.

As it is, every smartphone comes with a host of sensors to support its different functions. A light detector can seamlessly adjust brightness and camera settings, and a gyroscope can support compasses, for example. With earthquakes, the biggest element to ponder on is a smartphone’s movement and vibrations during an earthquake.

According to the lead engineer, figuring out the metrics for detecting an earthquake wasn’t a problem. After decades of accurate seismograph technology, developers already have an idea on what they need to measure.

However, the technology does not stop there. Naturally, there are hiccups to relying on just a single (or even every) phone’s data. For one, a city-wide messaging system can set off everyone’s phone in a single area, potentially causing false positives. Plus, relying on a single phone is definitely tricky. There are multiple actions which can cause vibrations akin to an earthquake.

Crowdsourcing a quake

The feature doesn’t rely on just one phone. It doesn’t tap into every Android phone in an area either. Instead, it collates data from phones plugged into a charger. Naturally, a plugged-in phone is the most reliable barometer in terms of battery reliability. They won’t die out in the middle of an earthquake and ruin a source of data. Additionally, charging phones are often stationary. They won’t be affected by motions that mimic earthquakes.

Google “listens” to charging devices in an area. If the subset meets the criteria for an earthquake, the company quickly determines the earthquake’s epicenter (based on approximate location) and magnitude. Once the system declares that a quake is indeed happening, it sends out an alert to nearby devices and gives them the time needed to seek shelter.

The alerts naturally prioritize people nearer to the epicenter. But, of course, the speed will ultimately depend on the phone’s connectivity. A phone hooked up to a building’s fast Wi-Fi connection will receive alerts faster than a commuter’s phone on data while going through a tunnel.

Still, the short time that the alerts give users is enough to save themselves from a precarious situation. Though the feature can potentially warn users of quakes minutes in advance, Stogaitis says that it will more realistically push alerts five to ten seconds before the incident. However, five seconds is enough to go under a table and have some sort of protection against falling debris.

Still keeping things private

For anyone worrying about how Google is handling their data, Stogaitis says that the company removes all identifiers from the data except for approximate location. And, despite that, Google still maintains that the feature will be the most accurate that it can be. Either way, the feature will be useful for any earthquakes in the future.

The earthquake sensor is available for any Android phone running Lollipop and above. Naturally, the feature still necessitates that users turn on emergency alerts on their phone.

The industry’s next big thing: Cloud gaming explained

It’s gaming on the go, but for internet that’s not slow

Published

on

Everybody’s getting into gaming these days, and you can’t blame them. With the pandemic continuing its ravaging ways in the world, people turn to their consoles or PCs for some action. However, not everyone can afford all the expensive PCs and the next-gen consoles when they come out.

Instead, a new player comes into the fray with a pretty great idea. What would happen if you can just play your favorite games from any device? Also, what if we told you that this won’t take up space on your device at all? This is basically what cloud gaming offers to you: a way to play games from any device at any time!

So, how does that actually work? What do you need to ensure quality gameplay, and should you even consider it?

The basics of playing on a cloud

On paper, it’s pretty easy to understand how cloud gaming works. Basically, you have access to a library of games from a cloud storage service. When you subscribe to the service, you can virtually play your library from any device regardless of the specs. Also, you don’t have to worry about storage problems since these games are stored on a server.

It’s no joke when these companies tell you that you can play your games on any device. With their dedicated data servers, they make sure that the games run smoothly once you access them from the cloud. On your end, you will need a strong and consistent internet connection to play the games smoothly.

Several companies already have cloud gaming software available for people to subscribe to. Some examples include NVIDIA’s GeForce Now, Microsoft’s xCloud, and Google Stadia — all of which store PC games on a server. These companies even take the time to update their server hardware every so often to bring the best possible quality.

System requirements for cloud gaming

Much like your ordinary PC or gaming console, companies that run cloud gaming servers need certain equipment to run smoothly. First, these companies must set up active data centers and server farms that run the games. These data centers ensure that games are up and running, while reducing latency. In other words, these serve as the powerhouse of cloud gaming.

Next on the list is the network infrastructure necessary to send these to the users. To ensure that people don’t experience lags when they play their games, companies also invest in acquiring proper data connections. However, in most cases, this isn’t something these companies have control over; it’s mostly coming from their available internet service providers.

On the front-end, companies also provide dedicated hardware and software to house the cloud. For example, NVIDIA integrated GeForce Now into their own cloud streaming device, the NVIDIA Shield back in 2013. Meanwhile, Google Stadia relies heavily on using pre-existing Google software like Google Chrome and the Stadia App.

Something great to offer, for the most part

Cloud gaming services offer something unique in the industry. Essentially, it eliminates the user from investing so much into buying expensive PCs as it allows people to play from virtually any device. Whether it’s on a smartphone, laptop, or even a smart TV, people get access to games at high frame rates without an RTX 3080.

Furthermore, the game and save files are stored on the cloud, and don’t take up any storage on your devices. This is greatly beneficial for people who are already running on limited storage space, especially if they play Call of Duty: Warzone. With everything stored on the cloud, you don’t need most of the 512GB of SSD storage.

However, one of the biggest issues with cloud gaming revolves around the thing it’s based on: the internet. Specifically, it’s on the user’s internet connection as these services require the fastest internet to run smoothly on any device. Basically, you will need either an Ethernet or a 5G wireless connection to ensure the lowest latency possible.

That infrastructure isn’t readily available in most markets, which is a prominent issue among several third-world countries. Furthermore, even if there are companies that have 5G in their pipeline, these same providers also put data caps on it. Even if the user can play at an optimal frame rate, they’re doing so with a restriction in place.

Does this new player have any place?

With the world continuously opening its arms to the gaming industry, innovation becomes the forefront of success. Companies come up with a variety of gaming technologies that seek to cater to a wide variety of people. From individual hardware to pre-built systems, gaming often revolved around these things.

With cloud gaming, it gives people not just another option within the mix. Rather, it seeks to challenge the notion of availability and accessibility, and give it a viable solution. Essentially, it takes away the physical hardware limitations on the user’s end, and makes it available for everyone.

But like most gaming technologies, everything is still limited somehow. These systems still experience bottlenecks both on the manufacturer and the user’s end. In the end, it will depend on how much you’re willing to shell out for them, and how willing you are to accept the risks.
