Monophony
In music, monophony is the simplest of musical textures, consisting of a melody (or "tune"), typically sung by a single singer or played by a single instrument player (e.g., a flute player) without accompanying harmony or chords. Many folk songs and traditional songs are monophonic. A melody is also considered to be monophonic if a group of singers (e.g., a choir) sings the same melody together at the unison (exactly the same pitch) or with the same melody notes duplicated at the octave (such as when men and women sing together). If an entire melody is played by two or more instruments or sung by a choir with a fixed interval, such as a perfect fifth, it is also said to be monophony (or "monophonic"). The musical texture of a song or musical piece is determined by assessing whether varying components are used, such as an accompaniment part or polyphonic melody lines (two or more independent lines). In the Early Middle Ages, the earliest Christian songs, called plainchant (a we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellular Phone
A mobile phone, cellular phone, cell phone, cellphone, handphone, hand phone or pocket phone, sometimes shortened to simply mobile, cell, or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called ''cellular telephones'' or ''cell phones'' in North America. In addition to telephony, digital mobile phones ( 2G) support a variety of other services, such as text messaging, multimedia messagIng, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, video games and digital photography. Mobile phones offering only those capabilities are known as fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Original Design Manufacturer
An original design manufacturer is a company that designs and manufactures a product that is eventually rebranded by another firm for sale. Such companies allow the firm that owns or licenses the brand to produce products while having to engage in neither the detailed engineering work required to specify a product for manufacturing nor the organization and running of a factory. (The ODM products may be the brand owner's primary business or may be a supplement to another line of business, such as general retailing.) This is in contrast to using a contract manufacturer, where the contracting company would design the product and supply those specifications to the manufacturer. Original design manufacturers have grown in size in recent years and, , many have the scale to handle production in-house for the products that are branded by the buying firm. This model is especially used in international trade, where a local original design manufacturer is used to produce goods for a foreign ...

OsmocomBB
Osmocom (open source mobile communications) is an open-source software project that implements multiple mobile communication standards, including GSM, DECT, TETRA and others. History and usage In 2008 Harald Welte and Dieter Spaar experimented with a base transceiver station from Siemens that was end-of-life and implemented the BSC side of the A-bis protocol, which eventually turned into OpenBSC. After attracting more interest, support for other BTS models was added. The first release of the OpenBSC project took place at the 25th Chaos Communication Congress held in December 2008. In the following years, the software has been used at various hacker cons such as the Chaos Communication Congress, Chaos Communication Camp and Electromagnetic Field to provide a cellular network. In 2010, a telephone-side implementation of the GSM stack was developed, named OsmocomBB. Together with OpenBSC, these projects became part of the new Osmocom umbrella project. The Sysmocom GmbH ...
