The latest chapter in the annals of standardization skullduggery–or, so far, alleged standardization skullduggery– involves the Universal Mobile Telephone System (UMTS) standard. Broadcom Corp., a manufacturer of semiconductor ICs (chipsets) for communications applications, has sued Qualcomm Inc., another chipset manufacturer and the owner of patents essential to complying with the standard. Br...

The cellular telephone success story prompts the wireless communications community to turn its attention to other information services, many of them in the category of "wireless data" communications. One lesson of cellular telephone network operation is that effective power control is essential to promote system quality and efficiency. In recent we have applied microeconomic theories to power c...

Augmented and alternative communication (AAC) devices enable users with certain communication disabilities to participate in everyday conversations. Such devices often rely on statistical language models to improve text entry by offering word predictions. These predictions can be improved if the language model is trained on data that closely reflects the style of the users’ intended communicati...

This article reviews the "first generation" of tailored print communications studies in the published literature, describing the purpose, theoretical framework, sample, research design, message type and source, outcomes measured, and findings of each. Eight studies compared tailored versus similar nontailored print; one compared tailored print versus an alternate intervention, and three include...

The future of integrated electronics is the future of electronics itself. The advantages of integration will bring about a proliferation of electronics, pushing this science into many new areas. Integrated circuits will lead to such wonders as home computers—or at least terminals connected to a central computer—automatic controls for automobiles, and personal portable communications equipment. ...

This research paper evaluates the development relationship between the adoption rate of Information and Communications Technologies (the Internet, mobile phone, pager, personal computer, and telephone) and per capita income gap between the urban and rural areas in China, mainly between 1985 and 2006. The Pearson’s correlation coefficients suggest there has been a strong correlation in the devel...

The increasing demand for high-bandwidth services such as corporate communications, fast Internet access and digital audio and video delivery presents both a great challenge and a great opportunity. To respond to this challenge, and to take advantage of the opportunity, the telecommunications industry is developing communication equipment based on clever implementations of highly efficient modu...

T he “net neutrality” debate, as it has emerged over the last five years, is a social, political and economic debate over the public information network known as the Internet and the duties of its private carriers, which include telephone and cable companies and other Internet service providers (ISPs). In the early 2000s, questions surrounding the rights of Internet carriers to block certain ne...

Long-distance telephone companies in the United States (U.S.) pay access fees to local telephone companies to transport calls that originate and terminate on their networks. These charges form the largest portion of the cost of providing long-distance service. Recent changes in the structure of access rates, which were mandated by the Federal Communications Commission (FCC), have created opport...

ENUM" is an Internet protocol designed to enable one to be reached on an array of different electronic communications devices by means of just one number – a telephone number. ENUM effectively bridges the telephone and Internet worlds by placing telephone numbers from the International Telecommunication Union (ITU) Recommendation E.164 public telecommunication numbering plan into the Internet D...
