Windows CE to stay here ? A ‘Real-time’ analysis.

Windows CE to stay here ? A ‘Real-time’ analysis.

After the advent of windows on ARM/Windows Phone 8, there is always a concern among the windows CE community on the future of Windows CE. When compared to windows on ARM/windows phone 8 there are many reasons to believe that windows CE is here to stay, in this blog I compare one of the interrupt handling features – priority inheritance mechanism, of Windows CE that determines its real-time capability. How predictable and reliable a system is, on reacting to an interrupt, defines its real-time effectiveness. When a common resource is shared among 3 tasks using Mutex there is a possibility of a situation where the high priority task had to wait for the lower priority task to release the shared resource. In this case the high priority  task remains blocked, causing a priority inversion situation where high priority task is indirectly pre-empted by a low priority task, effectively “inverting” the relative priorities of the two tasks, meaning the high-priority task has to wait for the completion of the lower...

FireFox OS and Android: Dual boot on Smart Phone

FireFox OS and Android: Dual boot on Smart Phone

Smartphones have become integral part of our life, where user likes to be connected always and use creative applications on shiny smart phone user interfaces. Today Android has captured the smart phone market and maturing which is completely open sourced. Operators and customers are looking towards an option alternative to Android. This is to enable user to have more options while buying phone and take advantage of different technologies. Users will be able to use HTML5 applications being developed by over 10 million HTML5 application developers. The number of HTML5 application developers is very big compared to about 1,00,000 iOS developers and about 5,00,000 Android developers. Firefox Smartphone operating system from Mozilla which is called as B2G (Boot to Gecko) meets all the features of smart phone with HTML5 application programming.  Gecko browser engine interfaces with below GONK HAL layer to talk to the hardware. Firefox GONK layer is built on top of android which means Linux kernel and core libraries of Android are adopted to execute Gecko and...

Wi-Fi Offload

Wi-Fi Offload

Smartphones growth is demanding higher data usage with 3G and LTE, this data usage is expected to explode going forward. Mobile industry has been looking at using Wi-Fi as a complementary access technology. With the advent of dual-mode handsets, Wi-Fi has become an access network alternative primarily to enhance coverage in doors. Current estimates show already more than 60% of content delivered to smartphones is provided over Wi-Fi access networks. Challenges Making Wi-Fi Offload Secure & Automatic Making Carrier Services Available on Wi-Fi Enhancing Network Discovery & Selection Monetizing Wi-Fi Hotspots Forging Partnerships across the Wi-Fi Ecosystem ePDG (LTE & eHRPD) and Wi-Fi Offload Non-3GPP accesses can be split into two categories: the “trusted” ones and the “untrusted”: Trusted non-3GPP accesses can interact directly with the EPC (Enhanced Packet Core) LTE network. Untrusted non-3GPP accesses interwork with the EPC via a network entity called the ePDG (for Evolved Packet Data Gateway). The main role of the ePDG is to provide security mechanisms such as IPsec tunneling of connections with...

Spoilt for choice – The completely swatchable phone

Spoilt for choice – The completely swatchable phone

Imagine walking into the friendly neighborhood phone store, selecting your hardware platform, choosing the OS that you want and going over a menu of possible enhancements to the standard fare.  That’s not where your choices will stop. You see what’s on offer for the camera, will you settle for the super megapixel camera of the OEM or insist on one from a specialist camera manufacture? Will you be content with the stereo speaker that come as standard fitment or go for the Hi-Fi special that will satisfy the  audiophile in you? Among the choices you can make are camera enhancements like clip on zoom lenses and filters, biometric readers, sensors of different kinds, memory size, battery type, charging options, pre-built application bundles, customized cases and the list could go on. It looks the Smartphone is poised to go the route that PC’s went through and offered the consumer a choice of hardware, operating system, application software and type of peripherals and add-ons. The auto industry too offers multiple options...

FAQ – Why mobile device and why mHealth?

FAQ – Why mobile device and why mHealth?

mHealth or mobile device driven healthcare delivery is slated as the next big wave amongst all the major stakeholders in the Healthcare ecosystem – Providers, Payers, Pharma and Lifesciences organizations. The typical mHealth benefits mentioned in various blogs, articles are: “Anytime Anywhere Access to Health Information”, “Physicians and nurses are always on the move and hence mobility”, “Most individuals have smartphones today and hence patient engagement can be greatly improved”, etc. These are all very valid and compelling reasons for the surge in mHealth. However, in our exchanges with various individuals in the health system (physicians, nurses, researchers, business development personnel, etc), we are frequently asked questions like – “Why mobile?”, “We have Mac stations and kiosks for patients, why do we need support for iPads and iPhones?” In augmentation to the typical mHealth benefits covered in various blogs and articles, listed below some scenarios that highlight benefits of mobility: Space benefits: Lots of situations requires e-engaging with a patient at the hospital premises. For e.g. asking a patient...
