Siemens S45
Announced in 2001, the Siemens S45 was Siemens' first ever GPRS mobile phone, allowing for faster data transmission and Internet access with the coupled dual-band GSM-900 and GSM-1800 networks The phone came with 360 KB of internal memory, which was considered generous at the time. This storage space was marketed as flexible because it could be manipulated like a hard disk via a supplied phone-to-serial cable, and the included software ensured that files could be transferred from the computer desktop to the phone in the drag-and-drop manner Later, Siemens released the S45i, with added E-mail client.

BenQ Mobile
BenQ Mobile GmbH & Co. OHG was the mobile communications subsidiary of Taiwanese BenQ Corporation, selling products under the BenQ-Siemens brand. The group, based in Munich, Germany, was formed out of BenQ's acquisition of the then struggling Siemens Mobile group in 2005. The newly formed company won the most iF product design awards in 2006 and also won many design awards in Germany's Red Dot competition. BenQ Mobile failed later that year. History Siemens Mobile was loss-making and struggling in the market, and the division was then sold to BenQ Corporation in June 2005 to try to turn the business around. As part of the deal, Siemens would pay BenQ at least 250 million euros to get the new venture to a solid start, in return of a 2.5% stake in BenQ. The acquisition was completed on 1 October 2005 with the formation of BenQ Mobile, led by a German CEO, Clemens Joos, and a Taiwanese chairman, Jerry Wang. Joos had already been president of Siemens Mobile since 2004. Part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Packet Radio Service
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 ...

Dual 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E-mail Client
An email client, email reader or, more formally, message user agent (MUA) or mail user agent is a computer program used to access and manage a user's email. A web application which provides message management, composition, and reception functions may act as a web email client, and a piece of computer hardware or software whose primary or most visible role is to work as an email client may also use the term. Retrieving messages from a mailbox Like most client programs, an email client is only active when a user runs it. The common arrangement is for an email user (the client) to make an arrangement with a remote Mail Transfer Agent (MTA) server for the receipt and storage of the client's emails. The MTA, using a suitable mail delivery agent (MDA), adds email messages to a client's storage as they arrive. The remote mail storage is referred to as the user's mailbox. The default setting on many Unix systems is for the mail server to store formatted messages in mbox, within the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Absorption Rate
Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed per unit mass by a human body when exposed to a radio frequency (RF) electromagnetic field. It can also refer to absorption of other forms of energy by tissue, including ultrasound. It is defined as the power absorbed per mass of tissue and has units of watts per kilogram (W/kg). SAR is usually averaged either over the whole body, or over a small sample volume (typically 1 g or 10 g of tissue). The value cited is then the maximum level measured in the body part studied over the stated volume or mass. Calculation SAR for electromagnetic energy can be calculated from the electric field within the tissue as: :\text = \frac\int_\textrm \frac d\mathbf where :\sigma is the sample electrical conductivity :E is the RMS electric field :\rho is the sample density :V is the volume of the sample SAR measures exposure to fields between 100 kHz and 10 GHz (known as radio waves). It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siemens Mobile Phones
Siemens Mobile was a German mobile phone manufacturer and a division of Siemens AG. Siemens sold Siemens Mobile to the Taiwan-based BenQ in 2005, subsequently becoming BenQ-Siemens and succeeded by Gigaset. The last Siemens-branded mobile phones, the AL21, A31 and AF51, were released in November 2005. History The first Siemens mobile phone, the Siemens Mobiltelefon C1, was launched in 1985. In 1994 the Siemens S1 GSM phone was launched. In 1997 Siemens launched the first phone with a colour screen, the Siemens S10, with a screen capable of displaying red, green, blue and white. In the same year Siemens launched the first " outdoor" phone, the Siemens S10 Active, with enhanced shock, dust and splash protection. Siemens launched the first slider phone, the Siemens SL10, in 1999. Siemens acquired the mobile phone division of Bosch in 2000. In the same year Siemens launched one of the first phones with an MP3 player and external memory card support ( MultiMediaCard), the Siemens S ...
