Nokia E7-00
The Nokia E7-00, also known as Nokia E7, is a smartphone by Nokia with a QWERTY keyboard that was marketed as part the business-oriented Nokia Eseries. It was announced at Nokia World in September 2010 together with the Nokia C6-01 and Nokia C7 and started shipping in February 2011, retailing for 495€ / HK$4898 / £375. As with the other two, it ships with the Symbian^3 operating system. When compared with the multimedia flagship of the time, Nokia N8, the E7 has fixed mass storage of 16GB without a memory card slot, no FM transmitter and a less advanced camera, with Extended Depth of Field, instead of autofocus as in the N8 and the E90. Like the Nokia N8, it comes with an HDMI-out connector and a non-user-replaceable battery that is smaller than the E90's. It has the same keyboard spring mechanism as the Nokia N97 mini, but has like the N8 an anodized aluminium casing. All this is different from the bulkier and heavier E90. Compared to the Nokia N97 mini and E90, the E7- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Read-only Memory
Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware. Software applications, such as video games, for programmable devices can be distributed as ROM cartridge, plug-in cartridges containing ROM. Strictly speaking, ''read-only memory'' refers to hard-wired memory, such as diode matrix or a #Solid-state ROM, mask ROM integrated circuit (IC), that cannot be electronically changed after manufacture. Although discrete circuits can be altered in principle, through the addition of Jump wire, bodge wires and the removal or replacement of components, ICs cannot. Correction of errors, or updates to the software, require new devices to be manufactured and to replace the installed device. Floating-gate ROM semiconductor ...

Nokia E90 Communicator
Nokia E90 Communicator is a high-end 3G mobile phone from Nokia, the fifth generation and final Communicator, also part of the Eseries. It was announced on 11 February 2007 at the 3GSM show in Barcelona. It succeeded the Nokia 9500 Communicator as the company's flagship business-oriented device. Its clamshell form and design are reminiscent of older palmtop computers. Unlike its predecessors, the E90 runs on the S60 platform of Symbian OS (3rd Edition Feature Pack 1 and v9.2 respectively). Previous Communicators meanwhile have been based on either GeOS or Symbian-based Series 80. The move to the common S60 was essential for software compatibility, but it did get rid of some exclusive Series 80 UI behaviours. The E90 is also the first Communicator to have UMTS/HSDPA connectivity and integrated GPS. It features OSGi and eRCP, Eclipse RCP for embedded systems. The first Nokia E90 unit was sold in an auction in Jakarta, Indonesia on 17 May 2007 for Rp. 45,000,000 (5,000 US ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nokia Eseries
The Nokia Eseries is a discontinued line of business-oriented smartphones running Symbian OS, produced by Nokia from 2005 to 2011. The Eseries brand became the partial replacement for the top-line products of the Nokia 6000 'Classic Business' range - the 6000 range itself would turn into a mid-range line with broad appeal beginning in 2007 mostly using the 'classic', 'slide' and 'fold' monikers. The Nokia Eseries have emphasis on enhanced connectivity and support for corporate e-mail push services, as well as enterprise-styled products and many featuring QWERTY keyboards. All devices have advanced office features through its S60 platform. Phones equipped with Wireless LAN also provide a VoIP client ( SIP Protocol). Throughout the series' lifetime its main competitors were BlackBerry products from Research In Motion. Models On October 12, 2005, mobile phone manufacturer Nokia Nokia Corporation is a Finnish multinational corporation, multinational telecommunications industry, ...

Ampere Hour
An ampere-hour or amp-hour (symbol: A⋅h or A h; often simplified as Ah) is a unit of electric charge, having dimensions of electric current multiplied by time, equal to the charge transferred by a steady current of one ampere flowing for one hour (3,600 seconds), thus equal to 3600 A⋅s or Coulomb. The commonly seen milliampere-hour (symbol: mA⋅h, mA h, often simplified as mAh) is one-thousandth of an ampere-hour (3.6 coulombs). Use The ampere-hour is frequently used in measurements of electrochemical systems such as electroplating and for battery capacity where the commonly known nominal voltage is understood. A ''milliampere second'' (mA⋅s) is a unit of measurement used in X-ray imaging, diagnostic imaging, and radiation therapy. It is equivalent to a ''millicoulomb''. This quantity is proportional to the total X-ray energy produced by a given X-ray tube operated at a particular voltage. The same total dose can be delivered in different time periods d ...

Enhanced Data Rates For GSM Evolution
Enhanced Data rates for GSM Evolution (EDGE), also known as 2.75G and under various other names, is a 2G digital mobile phone technology for packet switched data transmission. It is a subset of General Packet Radio Service (GPRS) on the GSM network and improves upon it offering speeds close to 3G technology, hence the name 2.75G. EDGE is standardized by the 3GPP as part of the GSM family and as an upgrade to GPRS. EDGE was deployed on GSM networks beginning in 2003 – initially by Cingular (now AT&T) in the United States. It could be readily deployed on existing GSM and GPRS cellular equipment, making it an easier upgrade for cellular companies compared to the UMTS 3G technology that required significant changes. Through the introduction of sophisticated methods of coding and transmitting data, EDGE delivers higher bit-rates per radio channel, resulting in a threefold increase in capacity and performance compared with an ordinary GSM/GPRS connection - originally a max ...

General Packet Radio Service
General Packet Radio Service (GPRS), also called 2.5G, is a mobile data standard on the 2G cellular communication network's global system for mobile communications (GSM). Networks and mobile devices with GPRS started to roll out around the year 2001; it offered, for the first time on GSM networks, seamless data transmission using packet data for an "always-on" connection (eliminating the need to "dial-up"), so providing improved Internet access for web, email, WAP services, Multimedia Messaging Service (MMS) and others. Up until the rollout of GPRS, only circuit switched data was used in cellular networks, meaning that one or more radio channels were occupied for the entire duration of a data connection. On the other hand, on GPRS networks, data is broken into small packets and transmitted through available channels. This increased efficiency also gives it theoretical data rates of 56–114 kbit/s, significantly faster than the preceding Circuit Switched Data (CSD) ...

Quad Band
In telecommunications, a multi-band device (including (2) dual-band, (3) tri-band, (4) quad-band and (5) penta-band devices) is a communication device (especially a mobile phone) that supports multiple radio frequency bands. All devices which have more than one channel use multiple frequencies; a band however is a group of frequencies containing many channels. Multiple bands in mobile devices support roaming between different regions where different standards are used for mobile telephone services. Where the bands are widely separated in frequency, parallel transmit and receive signal path circuits must be provided, which increases the cost, complexity and power demand of multi-band devices. The term quad-band describes a device that supports four frequency bands: the 850 and 1900 MHz bands, which are used in the Americas, and 900 / 1800, which are used in most other parts of the world. Most GSM/UMTS phones support all four bands, while most CDMA2000/1xRTT phones (mostly North A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
