This is especially true for OEMs using Android to develop Business IP phones, medical devicesand other such devices that have a greater need for security than consumer-grade home entertainment devices.
With innovation comes frustration.
Introducing a new idea or technology innovation is exciting, but every once in a while there comes an idea so big, consumers aren’t quite sure what to do with it.
If you’ve ever sat in gridlock when you have somewhere to be, you understand the feeling of wanting to rip the steering wheel from the console and start walking. It seems like the Jetsons were able to solve the problem, what is taking us so long?
When it comes to innovation in the automotive space, infotainment systems and smart dashboards are quickly becoming the next big thing. And while there are many different ways to build these systems using embedded technology, Android is proving to be a strong contender for the top OS. Why is embedded Android ideal for telematics development? How does it differ from other operating systems? We answer these questions and more in the infographic below.
It’s truly an exciting time to watch the landscape of wireless technology expand. As the demand for wireless connectivity continues to increase, this demand is pushing the capacity and efficiency of wireless technologies to their limits. There is, however, a light at the end of the tunnel.
ANDSF, which stands for access network discovery and selection function, is an entity within the EPC (evolved packet core) with the purpose of assisting UEs in the discovery/selection of access networks, such as WiFi, WiMax, and LTE, in their vicinity; providing them with rules policing the connection to these networks.
The famous fictional astronaut Buzz Lightyear once said: to infinity and beyond! Wise beyond his years, Buzz saw the potential for toys. In what’s become a disruptive innovation for traditional hard plastic dolls and board games, embedded toys are true game changers for the toy industry.
Most Android-powered devices have built-in sensors that measure motion, orientation, and various environmental conditions. These sensors are capable of providing raw data with high precision and accuracy, and are useful if you want to monitor three-dimensional device movement or positioning, or if you want to monitor changes in the ambient environment near a device.
An introductory article on the different technologies emerging in the wireless space can feel like an introductory article how to speak a foreign language. For some, the language makes sense; they’ve been around it, taken a couple classes and maybe even traveled to a place where that’s the only language spoken. For others, it can be intimidating the first few times you hear the words and phrases.
Wireless technology is ever-evolving, and there’s no end in sight. But where did it all begin? How did we get to where we are now? We’ve put together an infographic illustrating the transformations of wireless technologies from 1G in the 80s to the latest developments, to projections of connectivity in 2020. It’s been quite a journey, with many steps along the way – check it out!
Intelligent toys are not something of the future – they’re already here! Today’s version of smart toys though, is very different from what we can expect to see in the coming years. Recent updates to Android have made the OS ideal for developing interactive, smart toys that not only change the way we define “play,” but foster interactive learning like never before. Why are Android toys different? What are the benefits of using Android over any other OS in smart toy development? How does the future of intelligent toys differ from where we are today? Check out the graphic below for the answer to these questions, and more!
The future of wireless technology is bright…and crowded. As more of the population connects through mobile phones, smart watches, tablets, and the many other wireless devices available, the competition for access to WiFi and cellular networks is increasing faster than ever before. We’ve already touched on how offloading, small cell technology and nodes help alleviate some of the traffic in previous posts. But believe it or not there’s more to the equation.
The phrase, “I’ll try you on your cell,” is quickly becoming obsolete when it comes to messages left on landline answering machines. Not only are most American households turning away from landlines in general, but those remaining that still use them are starting make the switch to modernized versions of the now-archaic, traditional home phone. Some are even combining their home phone and mobile phone into a single smart device. But what’s all this about? Why does anyone care about having a home phone anymore? There have been a lot of developments recently in this realm…
Your grandfather probably remembers a time when men’s razors had just one blade. It was sharp and it got the job done…but with some scrapes and cuts along the way. Saturday Night Live famously mocked the addition of more razors saying “the 6th blade gently removes the 1stlayer of skin.” But all mocking aside, this is the age of more. In a world of innovation from analog to digital to 3G and to 4G, the next logical progression is a 5G network. Innovation, however, does not always care about logic or what makes sense. It made sense for Apple to develop their own mapping applications right? The buzz surrounding a 5G mobile network is real, but the question is, is it something to get excited about?
For those tracking the evolution of Android, it is evident that the future of the Android based ecosystem goes far beyond just phones and tablets. The OS is already making its way into a host of other smart devices, like Google Glass for example, in a movement toward what’s being called “the internet of things” or IoT.
Six hours? Eight hours? Ten hours?! We all have our number. How many hours of sleep does it take for you to fire on all cylinders the next day? How hard is it for you to get out of bed in the morning? It’s amazing, we spend a good percentage of our lives sleeping and yet, how often do we look for ways to maximize and improve that time? Well, technology isn’t only meant for use on-the-go, and more and more we’re seeing the market for sleep tech grow. So here are some great cyber-slumber technologies to help you feel well-rested, and make the most of your time in the sack.
The massive consumption of data combined with the growing popularity of “anywhere access” is putting a strain on mobile network operators. How will technology respond to this change? How will operators offload enough data to meet the increasing demand for service in increasingly remote areas? The answer is small cell technology.
With the advent of IP capable smart devices e.g. mobile phones, tablets etc. and easy internet access, there has been an exponential growth in data traffic. Cellular network operators have been trying to cope up with this ‘tsunami’ of data traffic by adopting new technological innovations like … read more
In January of 2014, Google acquired DeepMind Technologies for more than $400 million (according to MIT Technology Review) to become Google DeepMind. Google does a great job of picking up companies in the advertising, search, and other services as assigned space without much of a splash, but the purchase of DeepMind Technologies reverberated a bit more than most. Sometimes a Google acquisition is more than just the usurping of a company, but rather a validation of an idea – that there’s something to see, something worth getting behind more than just getting it out of the way to make room for your own project.
The MySQL cluster demands at least 4 nodes to be present for deploying a High Available MySQL database cluster.

Believe it or not, there are some college campuses in the United States that do not offer WiFi in their residence halls! There’s something about connecting an Ethernet cord to your laptop to research a paper about the future of nanotechnology or another innovative science just doesn’t gel. And while some college campuses are slow to adapt, there are plenty of industries looking beyond routers (also known as access points – which can refer to either a wireless AP or a standard AP) and central hubs to explore the up-and-coming world of WiFi mesh technology. The next generation of WiFi is here, and it’s not just about hotspots.
To survive, businesses must find innovative ways to stay competitive in their market. Not only is this true for their products and services, but also for the technology used internally within a company. When many people think of Android technology, they might think of the app store, some project management sites, and a means for checking email during an extended lunch. But embedded Android technology wields so much more power than a productivity checklist app. And if you don’t already know about it, you definitely should. So here are just a few waysbusinesses are leveraging the value of Android to operate smarter than their competition.
Lately, the Android OS has been experiencing phenomenal success. The most recent reports from IDC show that 81% of all smartphone devices sold in Q3 2013 are running Android. If you’re familiar with the industry, this may not surprise you. But what might surprise many people is that Android is being actively used in devices beyond smart phones – and the adoption rate is exploding in these areas as well. The operating system has already been deployed in business IP phones, medical devices, set top boxes, gaming consoles, car dashboards/rear-end systems and a variety of additional vertical markets with new ones coming up every month. Those who have been tracking our coverage of the benefits of using Android beyond phones (see our articles on IoT and Android vs Linux) already know that for any system currently based on Linux that has a need for a rich UX and networking options, Android makes a lot of sense.

The healthcare industry is a tough nut to crack when it comes to innovation. Sure new medical developments and discoveries are happening almost every day, and there’s a constant push for more understanding, better tools, and faster results. But the reality is that there’s a lot of red tape when anything new comes on the scene – especially when it comes to technology. Reasonably so, there are regulations that need to be followed when developing a new medical device, in order to keep patients safe, test results reliable, and medical professionals accountable. But even given the strict nature of the environment, the medical space is still transforming (however slowly) thanks to the use of embedded Android technology. Currently, there are three major trends that are paving the way to a better-connected medical industry. Check out our graphic below for more information on where embedded healthcare technology is headed.
When we start thinking about wearable technology, it’s easy to think about Star-Trek. Wearable technology came out of the engineering closet looking clunky, sci-fi-in-a-bad-way-y, and uncool. Luckily, wearable tech has made some strides in the fashion department. Here are a few devices that get us excited about a little skin to tech contact.
Marissa Mayer recently brought the Yahoo workforce back to the office. For years, Yahoo let their employees work remotely, as long as the job was done and done well. This all changed in 2013 when Mayer stated in a memo to staff: “To become the absolute best place to work, communication and collaboration will be important so we need to be working side-by-side.” But while Yahoo-ers have returned to the office setting, many others are doing the exact opposite. According to globalworkplacestatistics.com, the percentage of workers based in a home office has grown around 4% each year since 2009.
Last week, Austin Texas hosted SXSW. Thousands of people converged to discuss everything from start-up companies to trending music. It’s a great example of just how fast technology moves and ideas spread. Remember your first smart phone purchase? That feeling of holding all that powerful technology in your palm? The feeling of being un-tethered as you’re surfing the web on the subway…or in the stall. We’ve gotten so used to having this technology, that we forget how amazing it really is. Programmers and tech-like-minded individuals aside, most consumers take smart devices for granted. In the classic Louis CK bit on cell phones and flying, he points out “we have this beautiful device and we hate it! I’ve never seen a person say look at what my phone can do. They are always like, this piece of [expletive]” followed by a lot more colorful language. We get angry when downloads take longer than a few seconds because we forget that really, we’re waiting for signals from space!
Looking for the scoop on next season’s must haves? Well, maybe not next season, but the idea of smart devices as fashion accessories is definitely on the horizon. Sure, we’ve all heard about Google Glass by now, but what about the Sony SmartWig? Wearable tech is on the rise; helping us get things done, and look good while doing it. Here’s a sneak peak at what you can expect to see in the not-so-distant future.
Starting 2007 (launch of the venerable iPhone), Smart phones have changed the way we look at mobile communication. The erstwhile ‘mostly voice phone’ device suddenly transformed into a computing device and opened a new world of possibilities for mobile users.
Amazing User Experience (UX), … read more
As the adage states: the customer is always right. Companies like Zappos, Dillards, and probably even your local “ma-and-pa” grocery store have built their reputations on remarkable customer service. Zappos, for example, stands out from the clutter by encouraging website visitors to call their headquarters with any questions, 24-7. They’ve provided a unique personal touch in an increasingly person-less internet. Companies with attitudes like the Zappos team are rare, yet data shows that customers react positively to their approach. By investing more in customer service, they are able to generate more word-of-mouth referrals and decrease the amount of push advertising.
When we talk about the Internet of Things (IoT) we are talking about connecting everyday objects to the internet via low power signals. Kevin Ashton is credited with coining the phrase and being one of the first to write about the concept. He discusses how humans are great at doing many things, but capturing clean and accurate data about events happening in real time in the real world is not one of them. This ability to capture large amounts of data about everyday usage of everyday things is what makes the IoT such a powerful innovation.
When you hear the phrase “embedded system,” it’s easy to tune out and think: that’s tech talk. But the truth is, the concept of an embedded system is actually pretty easy to understand. Simply put, an embedded system is a computer system built within a larger mechanical system. Think of the alien controlling the larger human robot from Men In Black. The alien is the embedded system of the larger mechanical system (the human). Okay, so that’s not a real-world example, but you get the picture of small operating system under a larger umbrella.
While Android and Linux are relatively new to the scene, the concept of an embedded operating system is not as recent of a development as you may think. In fact, the history of embedded systems dates back to the 1960′s. But the technology has come quite a long way since then, and the evolution is likely far from over. Check out the graphic below for a quick rundown of how embedded technology got to where it is today, and where we see it going in the near future…and beyond!
Big data makes it possible to track and record information in ways George Orwell only dreamt…nay…night-terrored about. The “big brothers” in this digital age are the people behind the scenes taking billions and trillions of data points and making decisions based on the analysis. But fear not – this kind of information can be used for plenty of good! Big data is what makes Google more accurate in predicting flu-outbreaks than the CDC. Big data is what the Obama campaign team used to purchase undervalued television advertising times in highly valued swing-state zip-codes. And big data is what marketing professionals, supply chain managers, and decision makers at all levels are clamoring for more of.
It’s no secret that Android is transforming everything from turning on the television to higher education. More and more, Android-powered devices are found on the roads, the schools, and even in your kitchen. But Android is doing more than just making daily life more convenient; in the medical industry embedded Android technology is helping save lives.
Over the past 18 months, bare bones, mini-computing has surged in popularity due to low prices and high customization. These ARMs average roughly the size of a credit card and are great for those tinkerers looking to develop specialized, low-cost/no frills desktop replacements. They’re also perfect for building customized embedded solutions.
Home entertainment has come a long way since the days of strategizing with aluminum foil-topped black and white boxes. Embedded systems have made it possible to create a gaming, TV watching, and internet browsing experience in your home that rivals most movie theaters. Shopping for televisions used to be easy. Did you want a 13, 15, or 17 inch? Now, consumers are faced with decisions about adaptability, connectivity, and smart technology, not to mention many more size options. With literally thousands of decision points, not to mention ongoing development of new smart TVs and set top boxes, how is the average consumer supposed to prepare for the tech-talk their likely to experience in the electronics store? This is a quick guide to help make sense of the options.
When the Internet powerhouse Google purchases a company, it makes news. Funny that a corporation so visible to hundreds of millions online every day, can keep such suspense over their next move. Technology newsfeeds like Techcrunch and Mashable instantly predict “what this move means” for the future of the company and for the future of innovation. Let’s take a look at some of the more notable acquisitions as it relates to their current Android Operating System and the technology team they’ve produced.
The world of Android open source is helping ideas everywhere go from scratch-paper to product. From applications to video game consoles, open source encourages innovation and the destruction of the phrase “that’s impossible.” Here are open source canvases:
If you thought Android OS was just for smartphones and tablets, you’re in for a surprise. The use of the OS in other embedded systems and devices is growing exponentially, and it’s all because of the many benefits Android has to offer. To put it plainly, the developer community is using Android for embedded projects due to its flexibility, ease of customization, and compatibility. Want some technical insight into how Android stacks up against other operating systems? Check out the graphic below for a breakdown of the benefits of Android as an embedded platform:
The new year! A time for reflection, a time for celebration, and when it’s all over… a time to get back in shape. And while some of us will receive new toys and gadgets during the holiday season, most of those devices make it easier to be immobile. Smartphone controlled ovens, smart TVs, and other home automation systems make it easy to take the path of least movement. But there are some products looking to curb the lucrative lure of laziness. Using a remarkable combination of bio-analytics and embedded Android technology; individuals now have insights into their physical health that just might motivate them enough to head to the gym…or at least take the stairs!

The sheer notion of open source coding might paint an image of the Wild West where maverick, renegade hackers swoop in to steal passwords and social security numbers. While the Internet and open source software has provided the world with plenty of good, there is the unfortunate reality that we have to take the good with the bad. In this case, the bad are people who steal our information, property, and identities. Protecting yourself or your business from technology breaches is just as important, if not more important than remembering to close and lock the front door of your house.
Google Glass has arguably become the most talked about use case for embedded Android to date. The ambitious hardware project is powered by Android 4.0.3 – Ice Cream Sandwich. Until recently however, developers were only able to build apps for Glass using the Mirror API which basically exposes web applications to Glass but doesn’t really install an Android application on the device itself.
There was a time when using a map meant going to the drawer, pulling out a piece of paper, and manually locating street names and highways to find the quickest route, by yourself. Fast-forward to today and you have devices that can tell you how to walk, bike, take public transportation, or drive to just about anywhere in the world, and roughly how long it will take you to get there. We all know how to punch an address into our phone and hit start, but fittingly, this is just the beginning of what is possible with navigation technology. Welcome to the Android-age of mapping and directions.
Walking out of his job, Tim is psyched that it’s Friday. He steps into his car and uses his Android stereo to “call Shane.” Using Bluetooth technology, the infotainment system connects to his smartphone and dials his friend.
When it comes to supply chain management, there is no such thing as business as usual. The modern day supply chain is experiencing exponential innovation. Companies like Wal-Mart have fine-tuned this process to place their efficiency levels at competitive advantage heights. You might be thinking, but it’s a supply chain: raw materials, manufacture, ship, sell…everyone knows what to do so how can some be so much better? The same reason we all know that eating healthy and exercising is a good idea and yet many of us still neglect to do it; it’s hard work.
With the exception of mobile phones, Linux has long been the standard for embedded devices, such as gaming consoles, smart TVs, set top boxes, ECG, monitors, and other medical devices. However, for the past year or so, there has been a strong indication that Android could potentially replace Linux as the platform of choice for the next generation of connected devices.
Say goodbye to the traditional work environment. With embedded Android technology now powering so much more than just smartphones, many industries are leveraging the OS to increase efficiency, productivity, and security. The flexibility of Android as an embedded platform gives businesses the freedom to customize the system to meet their exact needs. Integrating Android with everything from conference room displays to X-ray machines, adoption of the OS at the enterprise level is trending steadily upward. Here’s a look at how Android is changing the nature of the workplace:
Some things never change…but most do. With advances in embedded technology, many of the items we use today look and feel like the products we’ve been using since their inception, but are actually hard-wired quite differently. Here are some products and procedures we regularly encounter that have come a long way thanks to Android operating systems.
Classrooms provide many of us with our first exposure to a new technology and innovation. It’s in these classrooms where we feel safe to experiment, explore, and sample. It shouldn’t be surprising, then, that many K-12 school districts across the country are adopting new Android technology not only to engage students, but to make the school system more efficient and connected.
A disruptive innovation is one that improves a product in ways the market does not expect. For consumers, the disruption is welcomed by early adopters and quickly becomes the norm. Think of Cirque du Soleil as a disruptive innovation to the Ringly Bros. Circus. While change at Ringly Bros. meant deciding between one more elephant or two more elephants, Cirque du Soleil revolutionized the entire concept of a circus; using people instead of animals to create a highly visual performance
In the book Where Good Ideas Come From by Steven Johnson, Johnson explains the adjacent possible as a series of rooms and doors. Growing on the idea that innovation takes time and great entrepreneurs often stand on the shoulders of the technology that came before (think YouTube using Adobe and internet connection). He uses the metaphor of rooms and doors to show what is possible right now: if you are in one room, you open a door to get to the next room and expand your world, but you cannot get to a room five doors down without first opening more doors and building more rooms in between.

Embedded systems are not just for business environments anymore. The technology is coming home, and Android OS is coming with it. When it comes to home automation, Android is the #1 operating system of choice for developers of smart appliances and devices. The idea of a smart home encompasses much more than just a phone or tablet available for communication/entertainment; these devices are becoming full-blown command centers for the house. Need to switch on the lights or monitor the status of your laundry? No problem. And it doesn’t stop there;embedded Android can be found in TVs, baby monitors, ovens, and even exercise equipment. We’re heading down the road to a fully-integrated smart home, but there’s already plenty of great devices and appliances available in today’s market. Here’s a look at how Android OS is changing the home life experience.
According to Google Executive Chairman Eric Schmidt, the new digital age is upon us. Pointing to futures in virtual reality, innovations in health sciences, and transportation breakthroughs from here to there, the world will soon be even more connected than it is today. So how do we get from here (modern technology) to there (new digital age)? When it comes to transportation, we’re closer than you might think. Below are four embedded technology trends gaining traction in the automotive industry.
