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]
Bronxville
Bronxville /ˈbrɒŋksvɪl/ is a suburban village in Westchester County, New York, located about 15 miles (24 km) north of midtown Manhattan.[3] It is part of the town of Eastchester. The village comprises 1 square mile (2.5 km2) of land in its entirety, approximately 20% of the town of Eastchester. As of the 2010 U.S. census, Bronxville had a population of 6,323.[4] As of 2014, it was ranked 18th in the state in median income.[5]
Millionaire real-estate and pharmaceutical mogul William Van Duzer Lawrence sparked the development of Bronxville as an affluent suburb of New York City with magnificent homes in a country-like setting.[6] The area, once known as “Underhill’s Crossing”, became “Bronxville” when the village was formally established. The population grew in the second half of the 19th century when railroads allowed commuters from Westchester County to work in New York City.[6] Lawrence’s influence can be seen throughout the community, including the historic Lawrence Park neighborhood, the Houlihan Lawrence Real Estate Corporation, and Lawrence Hospital. John F Kennedy, the president of the United States, also resided here for a time.[7]
The village was home to an arts colony in the early 20th century during which time many noteworthy houses by prominent and casual architects were built.[8] After the Bronx River Parkway was completed in 1925, the Village expanded rapidly with the construction of several apartment buildings and townhouses much of it built by the Lawrence family. As of 1959, they continued to own or manage 97% of the rental market.[9] In both rentals and ownership, the village discouraged and effectively prohibited Jewish residency, earning the name “The Holy Square Mile.”[9]
