No more cords: Wireless charging explained

More and more things are going wireless

Published

on

A lot of things have gone wireless over the past few years. From internet connections to gaming with your friends, the world is becoming more accessible without the need for physical wires. Over the course of 2018, another aspect of our lives has gone this route: charging one’s device.

Perhaps you’ve already heard of wireless charging and its presence in today’s smartphones, particularly the latest Apple devices. You may have even owned something that could wirelessly charge devices. But, what is wireless charging all about?

Let’s break down the technicalities

Wireless charging is a highly technical concept in the world of electronics. Basically, the way it works is that your charging pad contains coils that give off electromagnetic fields. These fields carry energy with them, which can be converted into electricity to power up the compatible device when placed on the pad. 

There are two ways devices can wirelessly charge: inductive charging and resonance charging. Inductive charging is mostly present in low-power charging devices, or ones that require less electricity to power up. This form is limited in range, to the point that the only way your phone charges is if it’s on the pad. Resonance charging, on the other hand, maximizes the range but lessens the amount of charge transferred.

Induction charging

Within the last ten years, several non-profit organizations have created and set wireless charging standards for companies to follow. The most popular of which is the Qi standard established in 2008 by the Wireless Power Consortium (WPC). Other standards include the Power Matters Alliance (PMA) standard in 2012, and Rezence by Alliance for Wireless Power (A4WP) from 2012 to 2015.

All about that Qi

As mentioned earlier, the Qi standard is the most popular wireless charging standard in the world. Most of today’s smartphones and peripherals are supported by Qi. It was established in 2008, with smartphones first adopting it in 2012 through the Nokia Lumia 920.

Qi focuses primarily on energy regulation. Most charging pads that use this standard work with flat surfaces for better energy distribution. Chargers with the Qi standard regulate the amount of charge they give to devices, and immediately go on standby once full. These chargers only activate once a device is placed on top, saving on the cost of electricity in the process.

Magnetic resonance charging

Most smartphone companies have made the choice to implement the Qi standard in their latest models. Apart from Nokia, companies like LG and Samsung have adopted it beginning with the LG Nexus 4 and Samsung Galaxy S6, respectively. In 2017, Apple accepted the standard with the release of their iPhone 8, iPhone 8 Plus, and iPhone X. The company also planned a charging mat called AirPower that could charge multiple devices all at once, but it has yet to be launched.

Why do most companies prefer Qi, but some don’t?

The goal of the WPC is to put forward one standard for wireless charging in the world. The organization developed the Qi standard in such a way that companies are able to integrate them into their products seamlessly. It’s because of this standard that smartphones are aligned to wireless charging pads through magnets for better charging capacity.

Apart from that, the Qi standard allows for more intelligent control over charging your phone. It can tell if your phone is fully charged and will stop sending electricity to avoid overdoing it. Of course, you’ll be able to maximize the charging capacity of your Qi wireless charger if you’re only charging one device at a time.

However, some companies recognize that most people own several smart devices. This is where other organizations like Power Matters Alliance come in. PMA initially used inductive charging as their base for wireless charging, which is what Qi uses, as well. Now, that same organization was able to look into resonance charging, which removes the limitation Qi has.

That’s one of the reasons why Samsung, for example, incorporated both Qi and PMA standards into their Samsung Galaxy S6. With resonance charging, devices can be charged a few centimeters away from the pad. This is especially good for people who use their phones while charging. While WPC is looking to incorporate resonance charging into Qi, certain factors and compatibility issues with devices make the standard less effective.

What does the future hold for wireless charging?

With all the talk about standards and devices, there’s no denying that wireless charging is here to stay. There are talks between the WPC and PMA on possibly coming up with just one true standard for all companies to follow. The best part is that it doesn’t stop there.

Both organizations are looking to expand their technologies beyond smartphones and consumer devices. WPC has already done so with furniture retailers like IKEA to apply wireless charging peripherals to office tables and couches. Meanwhile, PMA is looking to introduce wireless charging to restaurants and establishments, like McDonald’s and Starbucks with wireless-charging tables. It even reached a point wherein tech startups are developing their own hardware for wireless charging from longer distances.

It’s safe to say that the future is definitely bright for wireless charging. Whether companies will start making it a must-have feature for all their products remains to be seen.

What you need to know about Elon Musk’s Starlink

The much-awaited internet service is coming sooner than later

Published

on

Over the last few weeks, reports started pouring in about the possible arrival of Starlink internet service to the Philippines under a partnership between Converge ICT and SpaceX. These reports came after a senator’s meeting with representatives of SpaceX discussing the benefits, possible timeline, and requirements needed from the internet service.

These reports quickly became the talk of the town especially with the frenzy surrounding Starlink. You may have heard it before given the media attention it had received in the past. SpaceX — the company behind Starlink — promised fast network speeds and coverage almost anywhere around the planet with its internet service. There’s so much more to that though, so here are the things you need to know.

What is Starlink?

For those out of the loop, Starlink is a satellite internet service provided by SpaceX. SpaceX is a company founded by Elon Musk that builds next-gen space exploration technologies. The company is also behind the high-profile launches of reusable rockets as well its plans to bring people to Mars.

Starlink works through a constellation of small satellites. These satellites are placed in low to medium Earth orbit, communicating signals through an array of antennas and lasers. They work in tandem with dedicated ground transceivers to receive from and transmit signals to the satellites. In effect, the internet service relies on satellites instead of physical cables to provide an internet connection to consumers.

The technology behind Starlink is not a novel one, with the first satellite internet service dating back to the 1990s. However, most of these services ultimately failed due to logistical constraints and the prohibitive costs involved in setting things up. Granted, there had been few services that have seen some success but their adoption is few and far between. Reducing latency and lowering costs for consumers remain major challenges to many satellite internet providers.

Wanting to improve the whole situation, SpaceX began product development of Starlink in 2015. By 2018, it began testing its satellites which culminated in the launch of operational ones last 2019. Just last year, the company reached a milestone by launching up to 60 satellites at a time. This 2021, it is setting its sights for the global coverage of the populated world. Ultimately, SpaceX aims to put about 42,000 satellites in orbit in the future.

One goal of Starlink is to provide people in remote areas with a fast and reliable internet connection, which means a lot for developing countries like the Philippines.

How do I sign-up for the service?

Right now, the company is offering a limited beta service in the US and Canada. If you live in areas where the service is available, you can go ahead and sign-up for the service on Starlink’s website. Not all who signed up can avail of the service though since they are limiting their users at the moment on a first-come, first-serve basis. If you’re lucky, you may receive an email containing further instructions.

What does it feel like to use the service?

During its beta phase, Starlink claims speeds of 50 to 150 Mbps. Latency — which is also a crucial factor in internet-related tasks such as gaming and streaming — ranges from 20ms to 40ms. These figures are far from the advertised 1Gbps speed, as well as the advertised latency of 25ms to 35ms.

Still, those figures are fast enough for everyday use, especially when compared to other satellite internet services. Those figures are also close to the actual experiences by people participating in the limited beta service. For its part, Starlink promises continued improvement to network speed, latency, and software.

At the moment, the cost of signing up for Starlink is much higher than availing of a cable internet connection. The satellite setup kit is reported to cost around US$ 499 (PhP 24,000) while monthly fees start at US$ 99 (PhP 5,000). In comparison, PLDT’s internet plans max out at PhP 6,099 for 300Mbps while Globe’s internet plans max out at PhP 9,499 for 1Gbps.

To get connected, Starlink users must configure their setup kits and download the respective app. Each setup kit consists of the satellite dish, Wi-Fi router, power supply, cables, and a mounting tripod.

A clear view of the sky is also a prerequisite for a stable connection. As a note, weather disturbances can affect the connection between the user and the satellite infrastructure.

Starlink also requires its setup equipment to be stationary at all times. This is unlike cellular networks, which are designed to be mobile. While it offers a “wireless” connection to the internet, it still is “fixed” in the sense that it requires constant communication between the transceiver (the satellite dish) and the orbiting satellites.

When is it really coming to the Philippines?

Recent reports suggest that Starlink is coming soon to the country, but no definitive timeline has been given. Rumors suggested that the service will arrive later in Q3 2021. The most recent development squash any hopes of imminent arrival though, with Converge ICT stating that the partnership is still “premature”.

During the later weeks of February, however, Filipinos who signed up for Starlink started receiving a reservation email. The reservation fee costs around US$ 99 (approximately PhP 5,000) though it is fully refundable too. The email also details a possible coverage of the whole country by 2022. The exact date, however, remains unclear at the moment.

Likewise, the internet service still has many obstacles towards its widespread adoption in the country. The initial cost for would-be subscribers comes to mind. As mentioned, the approximate cost of Starlink hovers at PhP 24,000 with a monthly fee amounting to PhP 5,000. For that cost, you are getting better speeds with local telco offerings.

Despite its high cost, the promise of a fast and reliable internet connection is tempting especially in far-flung areas. Reaching out to these far-flung areas is a major challenge for all local telcos since the necessary physical infrastructure is non-existent or hard to setup.  Starlink could reach these areas easily, providing internet connection to those willing to shell out money.

Are there any other things that I should know about the service?

Starlink has garnered some concerns as well, with most directed towards its potential to cause light pollution. The potential to contribute to light pollution is a particular concern for astronomers. Apparently, Starlink’s satellites are bright enough to leave a trail of light, “photobombing” shots of the night sky. To this end, SpaceX said that it is already working on a solution to amend the problem.

As Starlink continues to push forward, more and more people are hoping to get aboard with the service. After all, a fast and reliable internet connection is still far from reality for many people living in remote areas. Hopefully, the service would come sooner as this will greatly improve the current situation of the internet in the Philippines.

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.
