Mobile Wireless Communications

Mobile Wireless Communications

Global System for Mobile Communication (GSM). Mobile Wireless Market: Technology Forecasts

Everything is converging. The wired world and the wireless world are converging. The Internet and mobile wireless is converging. The distinction between the wireless, wireline and the Internet service providers is beginning to blur. And the glue certainly is "mobile wireless".

Mobile wireless has exploded in popularity because of the fact that it simplifies and revolutionizes communication. The market for mobile wireless is increasing by leaps and bounds. The success of mobile communications lies in the ability to provide instant connectivity anytime and anywhere and the ability to provide high-speed data services to the mobile user.

1G - 1st Generation mobile communications

With the creation of the micro-processor and digitization of control links between mobile phones and cell sites in the 1970’s, the first generation of cellular standards (1G) was developed around Analog technology. In the early eighties, Europe was concerned with the issue that multiple standards were being developed across countries, but with no conformity. Compared to the United States that concentrated on standards development within its own boundaries, Europe took on a different strategic approach of focusing on unification of its mobile growth efforts.

VoIP Voice-Over-Internet Protocol

Voice-Over-Internet Protocol (VoIP)

VoIP (Voice-Over-Internet Protocol) - also known as Internet Protocol telephony (IP telephony) - is becoming a key driver in the evolution of voice communications.

Voice Over Internet Protocol (VoIP) is a telephony technology used to transmit ordinary telephone calls over the Internet. VoIP takes analogue audio signals and turns them into digital signals (packets) that are transmitted using Internet Protocol (IP) networks. VoIP's advantages include low cost, flexibility, and mobility. Conversely, VoIP's disadvantages include sound quality such as latency (delay), jitter, and packet loss. VoIP has a number of cultural, social, and regulatory impacts that solution providers must consider when marketing their services.

VoIP is a relatively new technology useful not only for phones but also as a broad application platform that enables voice interactions on devices such as desktop computers, mobile devices, set-top boxes, gateways, and many devices with applications specific to certain businesses where voice communication is an important feature.
