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 to telephony, 2000s-era 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 digital photography.As populations grow in certain areas, more and more prefixes are added to the list.You can find out even more than where on the map a cell phone prefix falls when you use an online locator.Verizon then inherited seven other Bell Operating Companies from AT&T following the latter's breakup.AT&T, Inc is the largest provider of landline telephony in the USA, and also provides broadband and subscription television services.Advanced systems determine the sector in which the mobile phone is located and roughly estimate also the distance to the base station.Further approximation can be done by interpolating signals between adjacent antenna towers.
It is also the largest company to have its headquarters in Dallas.
Verizon Communications, Inc is an international broadband and telecommunications company.
It is based in the Verizon Building in Lower Manhattan, New York City.
Qualified services may achieve a precision of down to 50 meters in urban areas where mobile traffic and density of antenna towers (base stations) is sufficiently high.
Rural and desolate areas may see miles between base stations and therefore determine locations less precisely.
