Jipp curve is a term for a graph plotting the number (density) of telephones against wealth as measured by the Gross Domestic Product (GDP) per capita. The Jipp curve shows across countries that teledensity increases with an increase in wealth or economic development (positive correlation), especially beyond a certain income. In other words, a country's telephone penetration is proportional to its population's buying power. [1] The relationship is sometimes also termed Jipp Law or Jipp's Law.
The Jipp curve has been called "[p]robably the most familiar diagram in the economics of telecommunications". [2] The curve is named after A. Jipp, who was one of the first researchers to publish about the relationship in 1963. [3]
The number of telephones was traditionally measured by the number of landlines, but more recently, mobile phones have been used for the graphs as well. It has even been argued that the Jipp curve (or rather its measures) should be adjusted for countries where mobile phones are more common than landlines, namely for developing countries in Africa. [2]
The term has sometimes been used in analogy for other curves as well, for example as a "postal Jipp curve" plotting letters posted per capita and GDP per capita. [4]
Brazil has both modern technologies in the center-south portion, counting with LTE, 3G HSPA, DSL ISDB based Digital TV. Other areas of the country, particularly the North and Northeast regions, lack even basic analog PSTN telephone lines. This is a problem that the government is trying to solve by linking the liberation of new technologies such as WiMax and FTTH) only tied with compromises on extension of the service to less populated regions.
Since being liberalized in 1991, the Colombian telecommunications sector has added new services, expanded coverage, improved efficiency, and lowered costs. The sector has had the second largest investment in infrastructure since 1997. However, the economic downturn between 1999 and 2002 adversely affected telecommunications. During this period, Colombia's telecommunications industry lost US$2 billion despite a profit of US$1 billion in local service. In June 2003, the government liquidated the state-owned and heavily indebted National Telecommunications Company and replaced it with Colombia Telecomunicaciones. The measure enabled the industry to expand rapidly, and in 2004 it constituted 2.8 percent of gross domestic product (GDP). Telefónica of Spain acquired 50 percent plus one share of the company in 2006.
The People's Republic of China possesses a diversified communications system that links all parts of the country by Internet, telephone, telegraph, radio, and television. The country is served by an extensive system of automatic telephone exchanges connected by modern networks of fiber-optic cable, coaxial cable, microwave radio relay, and a domestic satellite system; cellular telephone service is widely available, expanding rapidly, and includes roaming service to foreign countries. Fiber to the x infrastructure has been expanded rapidly in recent years.
Telecommunications in Pakistan describes the overall environment for the mobile telecommunications, telephone, and Internet markets in Pakistan.
Telecommunications in the Philippines are well-developed due to the presence of modern infrastructure facilities. The industry was deregulated in 1995 when President Fidel Ramos signed Republic Act No. 7925. This law opened the sector to more private players and improved the provision of telecom services are better and fairer rates, leading to the creation of many telecommunication service providers for mobile, fixed-line, Internet and other services.
Telecommunications in Sri Lanka commenced in 1858 after the first telegraphic circuit between Colombo and Galle was commenced. The sector continues to grow in the modern times.
Telecommunications in the United Kingdom have evolved from the early days of the telegraph to modern broadband and mobile phone networks with Internet services.
A telecommunications company is a kind of electronic communications service provider, more precisely a telecommunications service provider (TSP), that provides telecommunications services such as telephony and data communications access. Many traditional solely telephone companies now function as internet service providers (ISPs), and the distinction between a telephone company and ISP has tended to disappear completely over time, as the current trend for supplier convergence in the industry develops. Additionally, with advances in technology development, other traditional separate industries such as cable television, Voice-over IP (VoIP), and satellite providers offer similar competing features as the telephone companies to both residential and businesses leading to further evolution of corporate identity have taken shape.

International telephone calls are those made between different countries. These telephone calls are processed by international gateway exchanges (switches). Charges for these calls were high initially but declined greatly during the 20th century due to advances in technology liberalization. Originally they were placed via long-distance operators. The calls were transmitted by cable, communications satellite, radio, and more recently, fiber optics and Voice over Internet Protocol (VoIP). International direct dialling was introduced in the 1970s, so calls can be dialed by country code without an operator.

Telephone numbers in Pakistan are ten digits long. Landline numbers and mobile numbers have different structures.

The country code "91" was assigned to India by the International Telecommunication Union in the 1960s.
This article includes several ranked indicators for Chile's regions.
Telephone density or teledensity is the number of telephone connections for every hundred individuals living within an area. It varies widely across the nations and also between urban and rural areas within a country. Telephone density has significant correlation with the per capita GDP of the area. It is also used as an indicator of the purchasing power of the middle class of the country or specific region.
