Land-line Phone
The term is also used for the fixed line to describe the connection between two or more points, consisting of a dedicated cable, as opposed to always be available to a private link that is actually delivered in the circuit connected to the larger system (usually public switched telephone network using a network). So-called leased lines are invariably of the latter type, the impact on the fixed network in this context is the security and survival. For example, the headquarters of the armed forces may be combined with front line units, "the landline" to ensure that communication is still possible, even though the traditional telephone network is damaged or destroyed.
A fixed (or fixed) was originally an Overland telegraph wire, as opposed to a submarine cable. Currently, fixed (or land phone or main line or fixed line) refers to a telephone line that travels through a solid medium, wire or optical fiber is, which differs from a line of mobile cell, where transmission takes place via radio waves. In 2003, the CIA reported approximately 1.263 billion of main telephone lines worldwide. China has more than any other country of 350 million and the United States in second place with 268 million euros. In 2008, there were 1.27 billion fixed line subscribers in the world.
Mobile Phones
A mobile phone, mobile phone or hand is an electronic device used to make mobile phone calls over a wide geographic area served by many cells of the public that allows the user to be mobile. However, a wireless phone for use only within the scope of a private basis only, for example within a home or office.
Used mobile was first demonstrated by Dr. Martin Cooper of Motorola in 1973, with a combined weight of 2 kg.In 1983, the DynaTAC 8000X was the first to become commercially available. In the twenty years from 1990 to 2010, worldwide mobile phones increased by 12.4 million to over 4.6 billion dollars, entering and developing economies to reach the bottom of the pyramid.
A cell phone can make and receive calls to and from a public telephone network, which includes other mobile and fixed around the world. It does this by connecting to a wireless network provided by a mobile network operator.
Besides telephony, also modern mobile phones support a wide range of other services such as SMS, MMS, Email, Internet, wireless short-range (infrared, Bluetooth), enterprise applications, games and photography . Mobile phones that offer these more general computing capabilities are called smartphones.
smart phone
A smartphone is a mobile phone that offers high quality of the capacity of the most advanced computer connection and a modern phone functionality (ie, a modern low-end phone). A smartphone combines the functions of a personal digital assistant (PDA) and mobile phones. Today's models are usually also serve as portable media players and camera phones with high resolution touch screen, GPS navigation, Wi-Fi and mobile broadband access.
A smartphone complete operating system for mobile phones. Examples are widely used iOS Apple, Google Android, Microsoft Windows 7 Phone, Nokia, Symbian, Research In Motion BlackBerry OS, and embedded Linux distributions such as Maemo and MeeGo. Such systems can be installed on many different phone models. They can run third party applications, using an application programming interface (API)
A report by Olswang in early 2011, the adoption rate is accelerating smartphone: From March 2011 22% of UK consumers had a smartphone, this percentage was 31% between 24-35 years.They are different qualities of different types of smart phones.
Volpe Telephone
The VoIP phone uses Voice over IP (VoIP) technology that allows telephone calls to an IP network like the Internet instead of the ordinary PSTN system. Calls can browse the Internet or a private IP network, as a business. The phones use protocols such as Control Session Initiation Protocol (SIP), Skinny Client CONTRL Protocol (SCCP) or one of various proprietary protocols, such as that used by Skype.
VoIP Softphones are software-based devices or single-purpose with an appearance similar to a regular phone or cordless phone. Ordinary PSTN phones are used as mobile VoIP analog telephone adapters (ATA). You can have many features an analog phone is not compatible, such as email ID and contacts that may be easier to remember than names or phone numbers.
Satellite Phone
A satellite telephone, satellite phone, or satphone is a type of mobile phone that connects to orbiting satellites instead of terrestrial cell sites. They provide similar functionality to terrestrial mobile telephones; voice, short messaging service and low-bandwidth internet access are supported through most systems.
The mobile equipment, also known as a terminal, varies widely. Early satellite phone handsets had a size and weight comparable to that of a late-1980s or early-1990s mobile phone, but usually with a large retractable antenna. More recent satellite phones are similar in size to a regular mobile phone while some prototype satellite phones have no distinguishable difference from an ordinary smartphone Satphones are popular on expeditions into remote areas where terrestrial cellular service is unavailable.
