Linux Foundation to Host Meego Workgroup
Linux Foundation To Host MeeGo Workgroup New Open Source Software Platform Backed by Intel and Nokia will Power the Next Generation of Computing Devices SAN FRANCISCO, February 15, 2010 – The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux, today announced it will host the MeeGo project, the open source software platform for the next generation of computing devices. MeeGo combines Intel’s Moblin™ and Nokia’s Maemo projects into one Linux-based platform. MeeGo, announced today in a joint release by Intel and Nokia, will be deployed across many computing device types - including pocketable mobile computers, netbooks, tablets, mediaphones, connected TVs and in-vehicle infotainment systems, and brings together the leaders in computing and mobile communications as the project’s backers. MeeGo is designed for cross-device, cross-architecture computing and is built from the ground up for a new class of powerful computing devices. The workgroup will be hosted by the Linux Foundation as a fully open source project, encouraging community contributions in line with the best practices of the open source development model. The Linux Foundation expects MeeGo to be adopted widely by device manufacturers, network operators, software vendors and developers across multiple device types and for many organizations and developers to participate in the workgroup. “With MeeGo, you have the world’s leader in computing – Intel – uniting with the world’s leader in communications – Nokia – in a true open source project hosted at the Linux Foundation,” said Jim Zemlin, executive director at the Linux Foundation. “MeeGo has been built from the ground up for rich, mobile devices and will deliver choice to consumers without lock-in. -

Answer:- Jolla has revealed its plans to use the following technologies in Sailfish OS: The Mer software distribution core A custom built user interface HTML5 QML and Qt Read More Answers. Question # 3 Do you know about Sailfish OS software availability? Answer:- Sailfish will be able to run most applications that were originally developed for MeeGo and Android, in addition to native Sailfish applications. This will give it a large catalogue of available apps on launch. Considering upon Jolla's declarations that Sailfish OS is be able to use software from following platforms Sailfish (natively created + ported like from Qt, Symbian, MeeGo - developers have reported that porting a Qt written software with Sailfish SDK takes a few hours only) Android applications are directly running in Sailfish OS. They are compatible as they are in third-party Android stores, with no needed modification (in most cases). MeeGo (because of backward compatibility thanks to MeeGo code legacy included in the Mer core) Unix and Linux (as Sailfish is Linux then using such a software is possible, especially RPM packages, either in terminal/console mode or with limitations implying from using Sailfish UI, if not ported and adjusted) HTML5 Read More Answers. -

Download Android Os for Phone Open Source Mobile OS Alternatives to Android
download android os for phone Open Source Mobile OS Alternatives To Android. It’s no exaggeration to say that open source operating systems rule the world of mobile devices. Android is still an open-source project, after all. But, due to the bundle of proprietary software that comes along with Android on consumer devices, many people don’t consider it an open source operating system. So, what are the alternatives to Android? iOS? Maybe, but I am primarily interested in open-source alternatives to Android. I am going to list not one, not two, but several alternatives, Linux-based mobile OSes . Top Open Source alternatives to Android (and iOS) Let’s see what open source mobile operating systems are available. Just to mention, the list is not in any hierarchical or chronological order . 1. Plasma Mobile. A few years back, KDE announced its open source mobile OS, Plasma Mobile. Plasma Mobile is the mobile version of the desktop Plasma user interface, and aims to provide convergence for KDE users. It is being actively developed, and you can even find PinePhone running on Manjaro ARM while using KDE Plasma Mobile UI if you want to get your hands on a smartphone. 2. postmarketOS. PostmarketOS (pmOS for short) is a touch-optimized, pre-configured Alpine Linux with its own packages, which can be installed on smartphones. The idea is to enable a 10-year life cycle for smartphones. You probably already know that, after a few years, Android and iOS stop providing updates for older smartphones. At the same time, you can run Linux on older computers easily. -

5G's Future Is Hybrid – the Non-Terrestrial Opportunity
WHITEPAPER 5G’s future is hybrid – the non-terrestrial opportunity The technology and antenna innovations that are enabling hybrid terrestrial/non-terrestrial 5G networks Published by In partnership with Executive summary 5G is widely touted as a gamechanger in mobile broadband services in terms of data speeds, low latencies and massive connectivity features. And it is. But there’s far more to the disruptive power of 5G than fast speeds – it’s also about the resulting network architecture that brings new levels of flexibility and service innovations the mobile industry has never seen before. In fact, the architecture itself will be like nothing seen before in the mobile sector because it will be the first architecture to combine terrestrial and non terrestrial networks (NTNs) – including highaltitude platforms (HAPs) such as unmanned aerial vehicles (UAVs) and low earth orbit (LEO) satellites constellations – into a hybrid network providing true ubiquitous mobile broadband to every corner of the globe. Hybrid terrestrial/NTN 5G networks unlock new revenue and service opportunities for operators, not least the rural consumer market that operators have found too expensive to serve. Other possibilities range from rural business applications such as agriculture, forestry and mining to automotive apps, industrial IoT services, logistics and asset tracking and remote healthcare, to name a few. However, just as 5G needs to evolve from its current incarnation to the full promise of gigabit speeds and millisecond latencies, NTNs have their own evolutionary path to pursue before full integration can be achieved. Challenges abound, from link budgets and terminal costs to mitigating RF interference and high Doppler shifts.
