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.
DITO is all-in for the next generation of mobile connectivity
But what do they mean by this, exactly?
For as long as most Filipinos can remember, the Philippines has always had only two major mobile networks that they could choose from. This made the choice of network provider a bit simple but very limited for consumers. Recently, however, an actual third player came into the picture in the form of DITO Telecommunity.
While availability started back in March, DITO is making strides in terms of the services it’s offering. Currently, they are available in over 650 cities and municipalities across the country. Also, for the most part, these offers consist of high-speed data plans at an affordable rate. Where they want you to shift your attention to, however, is that their network also supports 5G connectivity. In their words, it’s the “next-gen technology” they want their consumers to experience.
So, what is this “next-gen technology” that they’re going on about?
Let’s review: the essence of 5G
The biggest thing about DITO’s new network service is their claim to bring “the real 5G” to the Philippines, at least according to DITO CTO Retired Major General Rodolfo Santiago. We had already talked about the whole 5G experience and what it brings to the table, so let’s not get into it too much. Basically, 5G serves as the next big thing in mobile connectivity, promising faster connections and wider coverage.
As such, telecommunication companies are opting-in to provide just that to its consumer base. However, like most new technologies, there are obstacles in the way that makes fast mobile data a little impossible to achieve. Well, DITO pretty much has that covered with what they call their world-class digital infrastructure.
Standing alone, or not standing alone?
While competitors began to introduce 5G to its consumers earlier, what they initially deployed was 5G non-standalone (NSA) network. This means that their 5G architecture is assisted by their existing 4G infrastructure. DITO, on the other hand, began developing their 5G standalone (SA) network since their rollout in 2019.
In theory, 5G standalone networks like DITO provides super-fast transmission speeds with ultra-low latency, which is suitable for most enterprises. Per its namesake, it relies heavily on its own 5G infrastructure instead of using its legacy 4G infrastructure as a jump-off point. In turn, DITO users will experience true 5G speeds every time they connect to the internet through mobile data. In other words, 5G standalone is “true 5G”.
With 5G standalone, DITO unlocks the “true 5G” in accommodating what 4G networks previously couldn’t. While it is building on what 4G connectivity initially offered, over time, it will eventually solidify itself as the standard for mobile connectivity.
The true goal for DITO
“Our goal has been to allow Filipinos to experience next-generation technology and we in DITO are excited to bring 5G to more areas in the country to truly transform digital connectivity and online interactions,” added DITO Chief Technology Officer Rodolfo Santiago.
For DITO, this is the “breakthrough connectivity” they want to bring to the general public. Apart from achieving greater mobile data speeds, each DITO SIM gives users access to more enhanced versions of innovations that are already widely available since the introduction of 4G. Two of which are VoLTE and ViLTE, the latter of which is something DITO proudly boasts.
Their next-gen offer: VoLTE and ViLTE
What exactly are these two innovations they’re enhancing with their services? Let’s start with VoLTE, mostly because this isn’t necessarily something new for most people. Simply put, Voice over LTE or VoLTE allows users to make voice calls without compromising mobile data speed. Normally, it’s an either-neither thing, wherein one use case will be a priority.
What is new is ViLTE, or as DITO calls it: Video over LTE, which works the same way as VoLTE but for video calls. In essence, users can make video calls from your device without the need for a video calling app. Also, these video calls are charged with the same rates as a normal voice call. However, this feature is currently limited to video calls between DITO subscribers.
Bringing it all together, DITO offers a package with faster connections and greater savings considering the innovations. It’s not something that a lot of other telcos are offering; for DITO, however, the experience doesn’t stop there.
Any phone will do, but what exactly do you need?
Upon its early availability, DITO released a list of compatible phones that supposedly bring out the telco’s best features. Like most providers, the DITO SIM works with any smartphone, 5G or not, for the bare minimum features like calling, texting, and mobile data. To experience “the real 5G,” however, they want a 5G device with a more standalone architecture.
For context, the 5G smartphones on this list come with either 5G NSA or 5G SA. The main difference between the two is, well, non-standalone architecture isn’t necessarily true 5G; rather, it is applying 5G to a 4G network. Meanwhile, 5G SA is its own 5G network, built and connected to 5G network bases to deliver higher speeds with lower latency than 4G.
In DITO’s case, only a handful of smartphones actually support the 5G SA architecture, which is where their 5G capabilities are built on. Currently, they are continuously exploring avenues to expand their network in order to bring “the real 5G” to more Filipinos, provided they have a supported smartphone. Again, these kinds of smartphones are a bit pricey, but to experience “the real 5G,” it’s not a bad trade-off.
The future is DITO (here)?
DITO enters the scene with the goal of bringing the next big thing in telecommunications, and their offer hinges on it. In their eyes, the promise of faster internet and wider coverage is already here, and it’s just a matter of getting people to opt-in. With its latest innovations, DITO provides a more enhanced mobile data experience.
To fully experience the next generation of technology, users must be properly equipped to wield such power. There’s a reason that DITO put out a device compatibility list upon initial launch: to provide users the best possible experience with all the features they have. Sure, any device will work with the DITO SIM, but certain devices give you that best experience.
Is it time to make the switch to the next-gen? In DITO’s eyes, the answer is simple and they’re waiting for people to join them.

How Google alerted the Philippines during the July earthquake
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.
