Nokia 2650
The Nokia 2650 was first made public in the second quarter of 2004. The model was one of Nokia's few clamshell releases at that time, and being an entry-level phone, it became popular largely due to its low price. Features The Nokia 2650 has the following features: * LED light for alerts to sms and incoming calls * A high resolution 128 x 128 colour display * Full colour xHTML via GPRS * Multimedia Messaging * An enhanced phone book with images added to contacts available * An enhanced calendar function * Downloadable Java games and applications, Wallpapers, Polyphonic ringtones Specification sheet References {{Nokia devices, 1000 series=yes, 2000 series=yes, 3000 series=yes, 5000 series=yes, 6000 series=yes, 7000 series=yes, 8000 series=yes, 9000 series=yes, 3-digit series=yes, asha=yes, cseries=yes, eseries=yes, nseries=yes, xseries=yes, 3-digit symbian=yes, lumia=yes, internet=yes, n-gage=yes, x family=yes, android=yes, originals=yes, c series=yes, g series=yes, x ser ...

Series 40
Series 40, often shortened as S40, is a software platform and application user interface (UI) software on Nokia's broad range of mid-tier feature phones, as well as on some of the Vertu line of luxury phones. It was one of the world's most widely used mobile phone platforms and found in hundreds of millions of devices. Nokia announced on 25 January 2012 that the company has sold over 1.5 billion Series 40 devices. It was not used for smartphones, with Nokia turning first to Symbian, then in 2012–2017 to Windows Phone, and most recently Android. However, in 2012 and 2013, several Series 40 phones from the Asha line, such as the 308, 309 and 311, were advertised as "smartphones" although they do not actually support smartphone features like multitasking or a fully fledged HTML browser. In 2014, Microsoft acquired Nokia's mobile phones business. As part of a licensing agreement with the company, Microsoft Mobile is allowed to use the Nokia brand on feature phones, such as the ...

Li-Ion
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible Redox, reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for Battery storage power station, grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy density, energy densities, low self-discharge, and no memory effect (although a small memory effect reported in Lithium iron phosphate battery, LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use Intercalation (chemistry), intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although Lithium–silicon battery, silicon-carbon is also being increasingly use ...

CSTN
Pioneering passive-matrix STN LCD, Brown Boveri, Switzerland, 1984 A super-twisted nematic display (STN) is a type of monochrome passive-matrix liquid crystal display (LCD). History This type of LCD was invented at the Brown Boveri Research Center, Baden, Switzerland, in 1983. For years a better scheme for multiplexing was sought. Standard twisted nematic (TN) LCDs with a 90 degrees twisted structure of the molecules have a contrast vs. voltage characteristic unfavorable for passive-matrix addressing as there is no distinct threshold voltage. STN displays, with the molecules twisted from 180 to 270 degrees, have superior characteristics. Features The main advantage of STN LCDs is their more pronounced electro-optical threshold allowing for passive-matrix addressing with many more lines and columns. For the first time, a prototype STN matrix display with 540x270 pixels was made by Brown Boveri (today ABB) in 1984, which was considered a breakthrough for the industry. STN ...

GPRS
General Packet Radio Service (GPRS) is a packet oriented mobile data standard on the 2G and 3G cellular communication network's global system for mobile communications (GSM). GPRS was established by European Telecommunications Standards Institute (ETSI) in response to the earlier CDPD and i-mode packet-switched cellular technologies. It is now maintained by the 3rd Generation Partnership Project (3GPP). GPRS is typically sold according to the total volume of data transferred during the billing cycle, in contrast with circuit switched data, which is usually billed per minute of connection time, or sometimes by one-third minute increments. Usage above the GPRS bundled data cap may be charged per MB of data, speed limited, or disallowed. GPRS is a best-effort service, implying variable throughput and latency that depend on the number of other users sharing the service concurrently, as opposed to circuit switching, where a certain quality of service (QoS) is guaranteed durin ...

UMTS
The Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology. UMTS uses wideband code-division multiple access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators. UMTS specifies a complete network system, which includes the radio access network (UMTS Terrestrial Radio Access Network, or UTRAN), the core network (Mobile Application Part, or MAP) and the authentication of users via SIM (subscriber identity module) cards. The technology described in UMTS is sometimes also referred to as Freedom of Mobile Multimedia Access (FOMA) or 3GSM. Unlike EDGE (IMT Single-Carrier, based on GSM) and ...

MIDP
Mobile Information Device Profile (MIDP) is a specification published for the use of Java on embedded devices such as mobile phones and PDAs. MIDP is part of the Java Platform, Micro Edition (Java ME) framework and sits on top of Connected Limited Device Configuration (CLDC), a set of lower level programming interfaces. MIDP was developed under the Java Community Process. The first MIDP devices were launched in April 2001. General APIs The core application programming interfaces are defined by the underlying Connected Limited Device Configuration system. javax.microedition.io Contains the Java ME-specific classes used for I/O operations. javax.microedition.lcdui Contains the Java ME-specific classes used for the GUI. LCDUI has a simple screen based approach where a single Displayable is always active at anyone time in the application user interface. LCDUI API provides a small set of displayables common in mobile device user interfaces: List, Alert, TextBox, Form and Canv ...

CLDC
The Connected Limited Device Configuration (CLDC) is a specification of a framework for Java ME applications describing the basic set of libraries and virtual-machine features that must be present in an implementation. The CLDC is combined with one or more profiles to give developers a platform for building applications on embedded devices with very limited resources such as pagers and mobile phones.CLDC Overview http://java.sun.com/javame/technology/cldc/overview.jsp The CLDC was developed under the Java Community Process as JSR 30JSR 30, CLDC 1.0 http://www.jcp.org/en/jsr/detail?id=30 (CLDC 1.0) and JSR 139JSR 139, CLDC 1.1 http://www.jcp.org/en/jsr/detail?id=139 (CLDC 1.1). Typical requirements CLDC is designed for devices that have limited processing power, memory, and graphical capability. Devices typically have the following features: * 16-bit or 32-bit CPU with a clock speed of 16 MHz or higher * At least 160 KB ROM allocated for the CLDC libraries and virtual mac ...

Bluetooth
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must meet ...
