Mobile / Wireless / Cellular Service
Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor.
The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters fortelevision or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPSunits, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones.
Somewhat less common methods of achieving wireless communications include the use of other electromagneticwireless technologies, such as light, magnetic, or electric fields or the use of sound.
The term wireless has been used twice in communications history, with slightly different meaning. It was initially used from about 1890 for the first radio transmitting and receiving technology, as in wireless telegraphy, until the new wordradio replaced it around 1920. The term was revived in the 1980s and 1990s mainly to distinguish digital devices that communicate without wires, such as the examples listed in the previous paragraph, from those that require wires. This is its primary usage today.
LTE, LTE-Advanced, Wi-Fi, Bluetooth are some of the most common modern wireless technologies.
A mobile phone is a telephone that can make and receive calls over a radio frequency carrier 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). Most modern mobile telephone services use a cellular network architecture, and therefore mobile telephones are often also called cellular telephones or cell phones. In addition totelephony, modern mobile phones support a variety of other services, such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming, and photography. Mobile phones which offer these and more general computing capabilities are referred to as smartphones.
The first handheld mobile phone was demonstrated by John F. Mitchell[1][2] and Martin Cooper of Motorola in 1973, using a handset weighing c. 4.4 lbs (2 kg).[3] In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. From 1983 to 2014, worldwide mobile phone subscriptions grew to over seven billion, penetrating 100% of the global population and reaching the bottom of the economic pyramid.[4] In 2014, the top mobile phone manufacturers were Samsung, Nokia, Apple, and LG.[5]
Coral Springs
Coral Springs, officially the City of Coral Springs, is a city in Broward County, Florida, United States, approximately 20 miles (32 km) northwest of Fort Lauderdale. As of the 2010 United States Census, the city had a population of 121,096.[5] It is a principal city of the Miami metropolitan area, which was home to an estimated 6,012,331 people at the 2015 census.
The city, officially chartered on July 10, 1963, was master-planned and primarily developed by WCI Communities, then known as Coral Ridge Properties, a division of Westinghouse. The city’s name is derived from the company’s name, and was selected after several earlier proposals had been considered and rejected.[6] Despite the name, there are no springs in the city; Florida’s springs are found in the central and northern portions of the state.[7]
During the 1970s, 1980s, and 1990s the young city grew rapidly, adding over 35,000 residents each decade. Coral Springs has notably strict building codes, which are designed to maintain the city’s distinctive aesthetic appeal. The city government’s effective fiscal management has maintained high bond ratings, and the city has won accolades for its overall livability, its low crime rate, and its family-friendly orientation.
Coral Springs is a planned community. Prior to its incorporation as a city in July 1963, the area which is now Coral Springs was part of 20,000 acres (81 km2) of marshy lands bought by Henry Lyons between 1911 and 1939. After several floods in 1947, Florida created the Central and Southern Florida Flood Control District (now the South Florida Water Management District). Canals and levees drained much of the area upon which Coral Springs was built. After the land was drained and cleared, most of the area was used as a bean farm. After Lyons’ death in 1952, his heirs changed the focus to cattle.[8]
A post-World War II real estate boom in South Florida attracted the interest of developers. Coral Ridge Properties, which already had several developments in Broward County, bought 3,869 acres (16 km2) of land from the Lyons family on December 14, 1961 for $1 million.[6]The City of Coral Springs was chartered on July 10, 1963. Other names that were considered for the new city included “Curran Village,” “Pompano Springs” and “Quartermore”. By 1964, the company had developed a master plan for a city of 50,000 residents. On July 22, 1964, the first sale of 536 building lots netted $1.6 million. The landmark covered bridge was built that same year to promote the town. In 1965, Coral Ridge Properties bought an additional 6,000 acres (24 km2) from the Lyons family, increasing the city’s land area to 16 square miles (41 km2). The first city government elections were held in 1967.
