First Android 4.3 hands-on video shows camera updated UI


Sony Xperia Z vs Google Nexus 4 aa (25)

After the first images showing Android 4.3 Jelly Bean running on a Nexus 4 at Thailand Mobile Expo surfaced, a first video showing the camera app updated UI has hit the web.

As you can see in the following video, only the camera app is shown (unfortunately), with the person recording the video not revealing other Android 4.3 features, although he or she clearly had access to the device. Not to mention that the video is recorded in portrait mode rather than landscape, but we’ll end our complaining there.

The video is pretty consistent with the images offered before and reveals that the button layout of the camera app has been redesigned to allow easy access to settings with just the thumb, without worrying about unintentionally pressing the wrong buttons.

Interestingly, a countdown timer feature is apparently available in the camera app on Android 4.3.

It’s still not clear why this particular Nexus 4 running Android 4.3 has shown up at Thailand Mobile Expo, and we’re certainly looking forward for more details about this particular sighting.

Google introduces natural language search and machine recognition for photos

You know what photos we’re searching for, right? (Image credit: Photographer / Shutterstock)

Search is increasingly becoming human. While users from my generation have been used to search operators like “and”, “or” and the plus and minus signs, search queries are becoming more and more natural language like. Take for instance Facebook‘s Open Graph search, which launched earlier this year with mixed reception. You can use natural language like “photos of my friends taken in Tokyo,” for instance.

Google has announced a better way to find photos, which uses natural language, as well as photo recognition. This new feature lets you search for photos within your Google+ network using simple queries. To make search even better, Google is now employing “computer vision and machine learning,” which will recognize even generic images based on their characteristics.

With this update, you can simply do a search for “my photos of flowers” and Google will come up with images of flowers from your Google+ photos. You can then add qualifiers to focus your search: “my photos of flowers in New York,” for instance. This has a few implications, of course. First, Google is moving toward doing away with tags and captions. With the new update, Google’s algorithms (neural networks?) will attempt to identify the image based on image recognition.

Photos of flowers from Google search

Product manager Matthew Kulick says this is limited to English searches within Google.com (no support for other country domains, yet), and when you are logged in via Google+.

Going beyond photo search, of course, the bigger implication that comes to mind is that this improvement will tie in well with Google Glass. With Google improving its image recognition technologyand having an improved ability in recognizing faces and objects, tying this in with persistent photo and video captured through wearable computers will become a rich source of data and analytics for the search giant.

 

HSPA+ vs LTE: Which one is better?


We have all marveled at the revolution in mobile communications technology. The 1980′s saw the introduction of the “brick” style wireless mobile phone accessible to a privileged few. Since then, we have seen a lot of shifting trends in designs and capabilities, but an exponential increase in availability and popularity. We now live in a world boasting over 6 billion mobile phone users, with most high-end devices mimicking the capabilities of a computer, featuring dual-core or even quad-core processing capability.

Ah, the Zach Morris brick.

I still recall a time when the primary purpose of a mobile phone was voice communication. Now, with smartphones bursting onto the scene in ever growing numbers, the mobile landscape is changing rapidly. With devices now featuring messaging, social networking connectivity, email and browsing capabilities, and the ability to stream or download high-quality music and videos, making and receiving calls has almost become a secondary feature.

Of course, none of this would be possible without an equally impressive evolution in mobile networking technology. From first generation communication networks to the current 4G craze, these advances have made it incredibly easy for any user to always be connected. Today we will compare the latest networking technologies, namely HSPA+ and LTE, and take a look at what the future holds.

History

First generation mobile networks were basic analog systems designed purely for voice calls. Mobile devices and call rates were very expensive and therefore not available to everybody. The early nineties saw the introduction of the first digital cellular networks. 2G brought with it improved sound quality and a higher capacity, allowing for data services, albeit at very low speeds up to 14.4 kbps. Further advances in this technology introduced GPRS and EDGE features with quicker data speeds between 40kpbs to 100kbps.

This was followed by the 3G revolution. Apart from wide-area voice telephony, it introduced high-speed internet access, far improved audio and video streaming capabilities, support for video calls and conferences, and internet TV. With effective speeds ranging from 128kbps to 384kbps, the advent of 3G completely changed the way people use their mobile phones.

The effective entry of the tablet and increasing dependency on handheld mobile devices led to demand for even faster speeds and connectivity options, leading to a new standard, HSPA+, followed by 4G LTE.

What is HSPA+ and LTE?

HSPA+

HSPA+ or Evolved High Speed Packet Access, is a souped-up version of HSUPA and HSDPA 3G standards with speeds comparable to the newer LTE networks. Theoretical speeds are said to feature download speeds up to 168Mbps and uplink of 22Mbps. These are of course theoretical speeds, with the actual speed available to users being much lower. While most HSPA+ networks around the world boast a theoretical 21Mbps(download) speed, T-Mobile(USA) and Deutsche Telekom(Germany) feature 42Mbps networks. A hotly debated issue is the 4G tag offered by cellular network companies to advertise their HSPA+ networks(T-mobile and AT&T), while most accept that it should be considered, at most, a 3.75G network.

LTE

On the other hand, LTE, or Long Term Evolution, is considered a “true” 4G network. Theoretical speeds boast downlink speeds of 300Mbps and uploads of 75Mbps. LTE, which is an IP-based system, is a complete redesign and simplication of 3G network architecture resulting in a marked reduction in transfer latency. Because of this, LTE is not compatible with 2G and 3G networks and thus, functions on an entirely different wireless spectrum. Unfortunately, this means that erecting an LTE network requires it to be built from the ground up. This is one of the main factors behind the delayed launch of  complete 4G LTE networks.

Bottom Line

HSPA+ is the tip of the mountain with 3G technology, and LTE is simply the foundation for a new mountain. LTE, also known as 4G, is the most advanced telecommunications technology currently available, and is one that defines a clear path toward future developments, making it the most attractive choice for carriers these days.

Speed Comparison

Neil Shah

The biggest question consumers have is whether the additional cost of buying an LTE-enabled device and the higher data charges are worth it, compared to the “slower” but relatively cheaper 3G and HSPA+ networks. Let’s take a look.

Under consideration are speed comparisons based on the recently conducted wireless speed tests byPCWorld, of the major network carriers in the US (AT&T, T-Mobile, Verizon, and Sprint). For our purposes, we are going to compare the LTE-based AT&T and Verizon 4G networks, against the 42 Mbps HSPA+ based T-Mobile “4G” network. While Sprint and T-Mobile both aim towards launching their LTE networks soon, as of now, they are based on Wi-Max technology and HSPA+ respectively.

PCWorld, along with their testing partners Novarum, conducted the tests using Ookla’s speed test app in 13 cities across the US including San Francisco, Los Angeles, San Jose, Seattle, Las Vegas, Denver, Dallas, Chicago, New Orleans, New York, Washington D.C., and Boston.

There are a few key points to note from the chart above:

  • T-Mobile’s HSPA+42 network performs admirably against, what is supposed to be, far superior LTE networks. The high speeds offered by this network should be more than enough for most users.
  • LTE is fast! While HSPA+ is definitely good enough, the LTE networks(in their current state) are 20-30% faster. A big plus for all the speed demons out there.
  • Unrelated to the topic, but is anyone as surprised as I am at how poorly Sprint’s Wi-Max network performed?

Granted these results for HSPA+ aren’t standard the world over, with most networks featuring 21Mbps download capabilities. But all these network carriers are planning to upgrade to 42Mbps and even 84 Mbps networks, so HSPA+ still has a lot of potential, and is certainly “good enough” for now.

As you can see from the map above, 4G LTE is certainly the network of the future. With the much faster speeds, higher efficiency, and increased reliability, it is the next logical step in network technology development. There are some key points to note about the map though, which shows that LTE coverage isn’t as “colorful” as it seems:

  • While a lot of countries are marked “red” indicating countries with commercial LTE services, it is slightly misleading. For example, while India as a whole is marked, only one carrier(Airtel) offers 4G LTE services in only one city(Kolkata) thus far. Of course, plans are in the works to rollout the network eventually, it will take quite a lot of time before complete coverage is achieved.
  • The above point is true for most countries, with none boasting a full coverage LTE network. Full coverage in some regions will be achieved at the earliest by late-2013 to early-2014, with most others much later.

On the other hand, HSPA+ is more along the lines of a software enhancement that elevates 3G data network performance. Of course, the process isn’t as simple as it sounds, but it is definitely easier than building a completely new LTE supported network. As such, any carrier that has an established 3G network, have upgraded to an HSPA+ network. With over 100 network carriers worldwide featuring HSPA+ networks with most boasting over 80% coverage. To keep up with current LTE speeds, carrier networks are also upgrading the their “slower” 21Mbps networks to 42Mbps or even 84Mbps (theoretical) download speeds.

Cost

As mentioned earlier, the biggest issue with taking advantage of the faster speeds of a 4G LTE network is coverage. Availability is still quite limited but that will of course, get better. What surprised me is the lack of a difference in cost between a carrier’s HSPA+ and LTE networks.

  • AT&T and Verizon have standard data rates of $50 for 5GB regardless of whether you have access to 3G, HSPA+, or 4G LTE networks.
  •  T-Mobile, which currently features a 42Mbps HSPA+ networks, also features the same data rates.
  • In India, while available only in Kolkata so far, 4G LTE costs Rs 1399(~$28) for 9GB, with HSPA+ being Rs 1250(~$25) for 10GB.

Of course, I’ve only used the information from two places I’m most familiar with, so there might be other networks worldwide where there is a more evident price difference (or not), so if there are, do let us know in the comments section.

Device availability

HSPA+ and LTE variations of the Samsung Galaxy Nexus

Device availability is another area where I consider LTE to be at a disadvantage. Here’s why:

  • Most smartphones and tablets (3G versions) released in the last 2 years or so can access the faster speeds offered by HSPA+ networks.
  • On the other hand, accessing a LTE network requires a significant hardware change, i.e. the need for an LTE radio.
  • Options for LTE capable devices are comparatively limited and generally range towards the higher end of the price spectrum.
  • There has been an incompatibility issue with latest Nvidia quad-core Tegra 3 processor and LTE radios, as seen with the HTC One X where the international version features the quad-core processor, and the US releases with LTE radios “falling back” on Qualcomm dual-core Snapdragon S4 processors. Whether this issue will be prevalent in other quad-core processors such as the Samsung Exynos 4412, is yet to be seen.
  • LTE radios are also infamous for being a huge drain on battery life.

The Future

HSPA+

Evolution of HSPA

HSPA+, with its theoretical 168Mbps downlink speeds, still wasn’t the pinnacle of HSPA technology. Back in 2010 began talk of LTHE or Long Term HSPA Evolution. LTHE brought with a lot of advantages including:

  • Backward compatibility with existing WCDMA and HSPA networks. This provided the possibility of an easy transition to LTHE as opposed to a network upgrade to LTE.
  • Theoretical download speeds up to a whopping 672 Mbps.
  • Carriers and hardware companies claimed that LTHE could have been ready for deployment by 2013.

Unfortunately, almost every network around the world has decided to move onto LTE as their network for the future. HSPA+ networks will likely be upgraded to the 42Mbps or even 84Mbps download capability, but now, it seems like that is as far as this evolutionary technology will be pushed.

LTE

While HSPA+ was the peak of 3G technology, the current variation of 4G LTE is only the first step in this next stage, opening up numerous possibilities for much further advancement in this field. It is somewhat strange that advances in LTE technology are already being spoken about when the “original” standard networks aren’t even close to being fully established. Yet, that is the rapid speed in which the tech world progresses. Let’s take a look at some of these developments:

  •  TD-LTE:  TD-LTE or Time-Division LTE was developed by China Mobile over the last few years. Unlike LTE networks which carries two separate signals for data traveling in either direction, TD-LTE features a single channel and allocated upload and download bandwidth depending on your usage. This accounts for higher data speeds. TD-LTE is also compatible 4G WiMax and it will easier to upgrade from WiMax to TD-LTE than to LTE.
  • LTE Advanced: LTE Advanced is a further evolution of current LTE networks which brings with it theoretical peaks of 1GBps download speeds, increased spectrum efficiency(upto 3 times more bandwidth), and reduced latency. Like the upgrade from HSPA to HSPA+, a move from LTE to LTE-Advanced is also a software deployment upgrade.
  • TD-LTE will also see a shift to TD-LTE advanced in the future.

Conclusion

Advantages of LTE over HSPA+

  • The most obvious advantage is the higher data speeds
  • Much better spectrum efficiency
  • Far lower latency
  • LTE has a simpler architecture compared to an HSPA+ network

Advantages of HSPA+ over LTE

  • HSPA+ is an already established network, whereas complete LTE coverage still has a while to go
  • HSPA to HSPA+ evolution required much less investment in infrastructure and was less costly to upgrade as opposed to LTE which needs a completely new network built from the ground up.
  • LTE requires specific LTE radio featured devices, whereas HSPA+ is available to any user with a 3G enabled phone.

As you can see, LTE is definitely the way of the future, and the potential with this technology is incredible. But I still think there are a lot of factors that lead me to conclude that HSPA+ networks are certainly more than enough for now.

What are your thoughts? Is HSPA+ good enough for now? Is LTE not here fast enough? Let us know in the comments section below. We’d love to know what you think!

Born to avert another 26/11, Heuristics Info Systems offers location based security systems


Sometimes opportunities knock at our door at the wildest of circumstances and take us off guard. For Amit Dubey and his team members at Heuristics Info, this happened with 26\11 Mumbai terrorist attacks. During this unfortunate incident the police was late to learn about the attacks and in the interim Railway Protection Force (RPF) guards were left at the mercy of the AK47s against their normal weapons.

PP

Heuristics Info System Pvt Ltd has emerged as a leading company in the field of location-based products, solutions and services. It offers VTS and Mobile Application software and provides unique cost effective quality solutions to various industry segments. The Heuristics team has an extensive experience in GPS Based Vehicle Tracking System (VTS) and Mobile Based Personnel Tracking Solutions, e-Beat, e-Investigation Solutions etc. Amit shares “In case of 26\11 attacks, management found out that the failure of beat operation co-ordination was because communication between RPF and Police was not made in time.”

Beat (patrol) is a very important activity of Police department, where constables at each station are assigned some important sensitive locations to patrol, such as hospitals, railway stations, bus stands, schools etc. They are supposed to keep an eye on these locations frequently, but in the former case there was no tool to ensure the patrol was done efficiently. To improve the scenario Punjab Police invited Heuristics Info to develop a tool to monitor their beat constables. Amit and his team members analyzed the whole situation and came up with Mobile Phone and Server based beat monitoring solution. It’s a client server based solution where a software runs in the background of the mobile phone which keep sending live location of a mobile to the server and if the mobile takes any image/video that also gets uploaded to the server instantly. This became a huge hit and subsequently they were recommended for e-governance award also. lt was deployed in Punjab Police as e-Beat/e-Investigation System on 6th Jan 2011. Following this success the startup started focusing on Private Industries and developed a very strong GPS/GIS Cloud based server platform which could track any GPS device available in the world.

Heuristics Info is led by Amit Dubey, as co-founder and CEO he has over 12 years experience in embedded and mobile software industry as senior manager with Samsung, ST-Micro and ST-Ericsson. He is also a renowned Crime Investigation Expert. Amit is well supported by Pradeep Rai (co-founder and CTO) and Rahul Shivhare. Pradeep has rich experience of 14+ years in Location Based Services and GIS Industry in Tele atlas Infotech, and TomTom. He also has expertise in developing highly optimized cloud based server solutions. While Rahul has 12+ Years in enterprise sales of Software Solutions, Experience with GPS, logistics and Fleet Management Industry. A total of 16 other members in the team also provide valuable support in strengthening the services.

The vision which was framed to help Indian Police Department was diversified to other business prospectus. Amit chips in “When we started developing the server solutions for various kinds ofebeatGPS tracking units, we realized the scalability potential of this business and we started identifying various gaps in this business. We thought of becoming number one GPS software service provider in India.” Their cloud based server now supports more than 150 different types of GPS trackers, these can be easily tracked on their server. They also offer a very specialized GPS Tracking Based Software Solution to Manufacturing Industries like Maruti and Transport Corporation of India (TCI), Coldex etc.

In August 2012 they had started office in Ghana and this year they have touched a partner count of 55 and achieved 800 + direct/indirect customers. Amit shares “The whole idea to select Africa (to expand our services) was to explore the under-developed markets. But we do have plans to expand to other countries as well. This year we opened an office in US and we are aiming for the same in UK as well.”

Heuristics was started with the initial savings from the founders, later they got a grant of 25 lakhs from Amity Incubator. They have been growing by 25-30% per month while focusing on the African market. Team Heuristics wish to touch a revenue count of five crores by the end of this financial year. They have also eyed to become a leader GPS software service provider in Africa by 2014/15.

 

CDAC Experience- Ist Year


My C-DAC(N) experince has me lot in my initiatves becasue it taught me how business and real life works. It has helped me produce working examples in my focus areas. It also taught me how mangerial function and decesion are made. My approach has been to gauge h0wI can apply the analytical skills and tools that i have learnt at C-DAC (in all my current initiatives. And I am tried my best to get value out of the MCA programmefro that I keeping my focous a lot. I never faced a lack of support from my peer and proffesors here at C-DAC. They encourage me in terms of giving me plateform to actually take my initiataves forward. I could participate in many of competition till now. The exposure has beenn tremendous. I personally feels that C-DAC(N) culture is an add-on-experience to my comming 2 years. I have to work hard, more than what i did at the undergrad level. But the best part is that is that i am here working with some of the great mind of the country. Beside, with the vibrant culture here at C-DAC(N) it is not all work and not to play. I also engage in fun student activities well . It also given me opportunites to arrange many movements in my hostl as well. According to me it is the tough of the programme that really one life in C-DAC(n) togeteher with the expirence of best learning. I has found my calling and i am also i am very clear in my mind about how i can my MCA degree to follow my passion. It is very important to have big dream of what is want to do in life and then pursue it. Search where i passionate sometime is may not ur dream fulfilled but is should continue in ur pursuit. I am a man for many season. If anything that distinguish myself from others is my fleeting interactin and my wit not to hurt anyone. Beside this, i work pretty early on projects as soon as possible. A bit of initiative, oppurtinity, luck landed me, till now is best in my programming part. Which Ipersonally feel i could on a much higher plane owing to my extrovert nature in C-DAC hostel. In C-DAC I have structured plan at the back of my mind to took at every opportunity as soon that could strenghten my candidature fo my IT career. Extracurricalars activities have always been part fo my pursuits and i belives that i am evolve holistacaly as a person owing to the diversity till which i lernt. One of the great experice till to tackle the confliciting priorites and keenness to strtech is the best part of C-DAC(N). At the end of first year this is my experience in C-DAC(N) Hostel and in college.
