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.
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.
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.
The industry’s next big thing: Cloud gaming explained
It’s gaming on the go, but for internet that’s not slow
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.
Your MagSafe Questions Answered
Do you really need it?
If you’ve ever owned an old MacBook before, you’ll know that those chargers magnetically snap onto place. That particular technology is called the ‘MagSafe’.
The MagSafe technology might not be new but the implementation for the latest iPhones makes the technology even more usable. Other than the securely-placed phone for wireless charging, there are a plethora of case manufacturers who continuously work on future accessories that support MagSafe existing ecosystem.
But is the Apple MagSafe more than just a gimmick? And do you really need it?
Watch our in-depth Apple MagSafe explainer here.
Here’s how India is trying to be China in the smartphone game
The world’s second-largest smartphone market has more to offer
China is practically the world’s production powerhouse. And India wants to follow the same path. India’s Central government has approved three schemes to enable large scale electronics manufacturing and attract fresh investments worth almost INR 50,000 crore (US$ 6.3 billion) in the sector.
The government aims to provide companies a production-linked incentive of 4 percent to 6 percent on incremental sales for locally made goods over a period of five years. This not only includes mobile phone manufacturing but also assembly, testing, marking and packaging.
The other policy offers a 25 percent financial incentive for capital expenditure that goes towards “the manufacturing of goods that constitute the supply chain of an electronic product”. With these incentives, the government is optimistic that companies will come to India, contribute to progressing infrastructure, and make export-quality goods.
According to their estimates, domestic value addition for mobile phones is expected to witness 35 to 40 percent jump by 2025, from the current 20-25 percent.
So far, companies have focused on assembling equipment like smartphones in India. A huge chunk of the components are still imported. These policy changes could act as a stimulant to locally source electrical components, semiconductors, as well as develop production clusters.
Bangalore and Hyderabad are infamous for their IT Tech Parks that house thousands of employees from IT service firms like TCS, Infosys, Accenture, and many more. Similarly, the government wants to create production clusters that can develop an eco-system of their own. These clusters can create a seamless supply chain when paired with proper land, air, and shipment infrastructure.
The timing of the announcement is what matters the most. China is embroiled in a trade war with the US for quite some time and we’ve seen how a giant like Huawei got caught in the cross-fire. Companies are skeptical about depending too much on China for production and sourcing. Hence, countries like Vietnam have witnessed a huge inflow of foreign investment from the likes of Nintendo, Foxconn, and even Samsung.
India is very much like Vietnam. A developing economy that’s on the look-out for foreign investment and enhances local production capabilities. This not only helps the government increase its tax revenue via taxation, but also provides employment. Considering the current Coronavirus crisis, it’s obvious that these plans may not materialize soon. But, as soon as the storm is gone, companies would want to find an alternative to China.
It’s reported that the alleged low-cost iPhone from Apple has been delayed due to the pandemic. Irrespective of the current health crisis, Apple has been trying to ramp up its local production in India and has done so, cautiously. India is the world’s second-largest smartphone market and every brand wants a piece of the cake. Realme and Xiaomi have been intensely fighting for supremacy, Samsung continues to lead via the offline market, and OPPO and Vivo have flooded all commercial banners with their products.
Xiaomi currently has seven plants in India, major ones being at Sri City and Sriperumbedur. It also makes its televisions in Tirupathi. Manu Kumar Jain, Vice President, Xiaomi, and Managing Director, Xiaomi India said that 95 percent of Xiaomi’s phones are made in India with 65 percent of a phone’s value being sourced locally. The government has been successful in compelling companies to make in India because it consistently kept on raising import duty on smartphones.
Samsung already has the world’s largest mobile phone factory in India that assembles top-tier variants, ready for export. We don’t know the volume it churns out right now, but their long-term investment is a precedent for other brands to take the market seriously. OnePlus has a research facility in Hyderabad where it makes software products intended for the Indian market.
According to industry ICEA, the NOIDA region (a part of Delhi NCR) has close to 80 mobile manufacturing factories that provide employment to approximately 50,000 people. It’s normal today to see companies release press notes announcing new facilities across the country that’ll employ thousands of people.
Prime Minister Narendra Modi kickstarted the “Make in India” campaign five years ago to encourage foreign companies to invest and build in India. While its effects are debatable in a few industries, there’s no doubt that the mobile industry has picked up exponentially. State governments of Karnataka, Andhra Pradesh, Telangana, Uttar Pradesh, and Tamil Nadu have played a major role in establishing these clusters that symbolize progress.
Engineers are widely available in India, the country has developed multiple ports under the private-public model, and numerous airports are under construction. India is already the world’s second-largest smartphone maker, but the gap is huge. It’s about briding this. Obviously, the scale at which China produces is unmatchable. But that cannot undermine India’s efforts to be more relevant on the global stage. From a purely consumption-based economy, it’s slowly trying to turning into a production backed state.
