List Of Open-source Mobile Phones
This is a list of mobile phones with open-source operating systems. Scope of the list Cellular modem and other firmware Some hardware components used in phones require drivers (or firmware) to run. For many components, only proprietary drivers are available (open source phones usually seek components with open drivers.) If firmware is not updatable and does not have control over any other part of the phone, it might be considered equivalent to part of the hardware. However, these conditions do not hold for cellular modems. , all available mobile phones have a proprietary baseband chip (GSM module, cellular modem), except for the Necuno, which has no such chip and communicates by peer-to-peer VOIP. The modem is usually integrated with the system-on-a-chip and the memory. This presents security concerns; baseband attacks can read and alter data on the phone remotely. The Librem 5 mobile segregates the modem from the system and memory, making it a separate module, a confi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DragonBox Pyra Mobile Edition
The DragonBox Pyra is an upcoming Linux-based handheld computer equipped with a keyboard and gaming controls. The project entered prototyping stage in 2015. Pre-orders began on 1 May 2016, with a final release date still undefined. In August 2020 the first production model had been shipped, but only to developers, as the software wasn't ready. History The ''Dragonbox Pyra'' is the spiritual successor of the OpenPandora device, and shares some of the original Pandora team members. The Pyra is designed and developed in close connection with the OpenPandora community, taking their feedback and experience with the Pandora into account. The OpenPandora GmbH, residing in Germany, organizes design, prototyping and the production in Europe (Greece and Germany). The Pyra was presented officially at the FOSDEM 2014 in Brussels. In 2015 several working developer prototypes of the Pyra have been produced and were given to software developers for evaluation and software creation. Devel ...

Mobile Phone Standards
This is a comparison of standards of mobile phones. A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s. Issues Global System for Mobile Communications (GSM, around 80–85% market share) and IS-95 (around 10–15% market share) were the two most prevalent 2G mobile communication technologies in 2007. In 3G, the most prevalent technology was UMTS with CDMA-2000 in close contention. All radio access technologies have to solve the same problems: to divide the finite RF spectrum among multiple users as efficiently as possible. GSM uses TDMA and FDMA for user and cell separation. UMTS, IS-95 and CDMA-2000 use CDMA. WiMAX and LTE use OFDM. * Time-division multiple access (TDMA) provides multiuser access by chopping up the channel into sequential time slices. Each user of the channel takes turns to transmit and receive signals. In reality, only one person is actually using the chan ...

Mobile Linux
Linux for mobile devices, sometimes referred to as mobile Linux, is the usage of Linux-based operating systems on portable devices, whose primary or only Human interface device (HID) is a touchscreen. It mainly comprises smartphones and tablet computers, but also some mobile phones, personal digital assistants (PDAs) portable media players that come with a touchscreen separately. Mobile Linux is a relatively recent addition to the Linux range of use, with Google's Android operating system pioneering the concept. While UBPorts tried to follow suit with Ubuntu Touch, a wider development of free Linux operating systems specifically for mobile devices was only really spurred in the latter 2010s, when various smaller companies started projects to develop open source phones.

Openmoko
Openmoko is a discontinued project to create a family of open source mobile phones, including the hardware specification, the operating system (Openmoko Linux), and actual smartphone development implementation like the Neo 1973 and Neo FreeRunner. The whole project was sponsored by Openmoko Inc. The first sub-project was Openmoko Linux, a Linux-based operating system designed for mobile phones, built using free software. The second sub-project was developing hardware devices on which Openmoko Linux runs. The first device released was the Neo 1973, in 2007, which was followed up by the Neo FreeRunner on 25 June 2008. On 2 April 2009, Openmoko suspended development of their third device, codenamed GTA03, to focus on the FreeRunner. In 2010, development of the GTA03 was continued by Golden Delicious Computers under the new codename GTA04, which includes major hardware revision, and the first unit was shipped on 10 October 2011. Unlike most other mobile phone platforms, these ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BQ Aquaris E4
The becquerel (; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. For applications relating to human health this is a small quantity, and SI multiples of the unit are commonly used. The becquerel is named after Henri Becquerel, who shared a Nobel Prize in Physics with Pierre and Marie Skłodowska Curie in 1903 for their work in discovering radioactivity. Definition 1 Bq = 1 s−1 A special name was introduced for the reciprocal second (s−1) to represent radioactivity to avoid potentially dangerous mistakes with prefixes. For example, 1 µs−1 would mean 106 disintegrations per second: 1·(10−6 s)−1 = 106 s−1, whereas 1 µBq would mean 1 disintegration per 1 million seconds. Other names considered were hertz (Hz), a special name already in use for the reciprocal second, and Four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BQ Aquaris E5
The Aquaris E5 and Aquaris E5 FHD are dual-SIM Android smartphones from the Spanish manufacturer BQ that were released to market in July 2014. The devices shipped with Android 4.4 (KitKat). BQ elected not to skin the operating system and as such it retains the unmodified "Google Experience", such as found on the Google Nexus. On 9 June 2015 BQ in partnership with Canonical launched the Aquaris E5 HD Ubuntu Edition. The phone is based on the Aquaris E5 hardware (with the 1280×720 screen) and was sold in the European Union only. Notably, this is only the third phone to be sold with the Ubuntu Touch mobile operating system, after the BQ Aquaris E4.5 and the Meizu MX4.

Ethernet Port
Ethernet () is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the latest , with rates up to under development. The Ethernet standards include several wiring and signaling variants of the OSI physical layer. Systems communicating over Ethernet di ...
