Verizon is an American wireless network operator. The mobile network previously operated as a separate division of Verizon Communications under the name of Verizon Wireless. In a 2019 reorganization, Verizon moved the wireless products and services into two new divisions, Verizon Consumer and Verizon Business, and stopped using the Verizon Wireless name. Verizon is the largest wireless carrier in the United States, with 121.3 million subscribers as of the end of Q2 2021.[4]

The company is headquartered in Basking Ridge, New Jersey. It was founded in 1998as a joint venture of American telecommunications firm Bell Atlantic, which would soon become Verizon Communications, and British multinational telecommunications company Vodafone.[5] Verizon Communications became the sole owner in 2014 after buying Vodafone's 45-percent stake in the company.[6]

It operates a national 4G LTE network covering about 99 percent of the U.S. population,[7] which in the second half of 2020 won or tied for top honors in each category of the RootMetrics RootScore Reports.[8] Verizon Wireless offers mobile phone services through a variety of devices.[9] Its LTE in Rural America Program, with 21 rural wireless carriers participating, covers 2.7 million potential users in 169 rural counties.[10] Verizon Wireless announced in 2015 that it was developing a 5G, or fifth-generation, network.[11]

History

Verizon's original logo, used from September 1998, to September 1, 2015. It is still seen on the front of many stores.

In September 1999, American phone company Bell Atlantic and British-based Vodafone Airtouch PLC proposed they would create a new wireless phone service joint venture valued at $70 billion.[12] The joint venture was being created as Bell Atlantic underwent a merger with GTE Corporation. In April 2000, the companies announced that the Bell Atlantic–GTE merger would take the name Verizon and that the Bell Atlantic–Vodafone wireless unit would be called Verizon Wireless (legally Cellco Partnership d/b/a Verizon Wireless).[13] Verizon Communications owned 55 percent of Verizon Wireless while Vodafone retained 45 percent ownership.[5] Regulators with the Federal Communications Commission approved the Bell Atlantic–GTE merger on June 16, 2000,[14] creating the largest wireless company in the United States.[15] Verizon Wireless held this market position until Cingular acquired AT&T Wireless Services in 2004.[16]

Throughout the 2000s, Verizon acquired several wireless phone companies and assets across the country, including West Virginia Wireless in 2006;[17] Ramcell in 2007;[18] Rural Cellular Corporation[19] and SureWest Communications, both in 2008.[20] Also in 2008, Verizon struck a deal to buy Alltel for $5.9 billion in equity while assuming $22.2 billion worth of debt.[21][22] The deal finalized January 9, 2009, again making Verizon Wireless the country's biggest cellphone network.[21] As per the agreement, Verizon sold rural wireless properties across 18 states to AT&T. Those properties were in Alabama, Arizona, California, Colorado, Iowa, Kansas, Michigan, Minnesota, Montana, Nebraska, Nevada, New Mexico, North Dakota, South Dakota, Tennessee, Utah, Virginia and Wyoming.[23] Verizon's acquisitions continued in the 2010s, including the purchases of some Plateau Wireless markets in 2012[24] and Golden State Cellular's operator in 2014.[25]

Majority owner Verizon Communications became sole owner of its wireless business in 2014, when it bought Vodafone's 45 percent stake.[26] Vodafone received $58.9 billion cash, $60.2 billion in stock and $11 billion in other transactions.[6][27] An article in The New York Times estimated Verizon Wireless' valuation at about $290 billion.[6]

In late 2014, it became known that Verizon Wireless uses deep packet inspection for server-side insertion of a customer-unique ID field ("X-UIDH") into all unencrypted HTTP headers. The mechanism has been referred to as "supercookie" or "perma-cookie", although it is not technically a cookie in that it does not store information on the customers device and is transparent to the user. It can not be averted with common mechanisms like ad-blockers; however it can not be inserted into encrypted HTTPS and VPN connections. Verizon advertises the system to marketing partners. The Electronic Frontier Foundation has called on Verizon to terminate the program, calling it a "profound violation of trust", expressing concern over abuse by third parties, and questioning the legality of Verizon modifying their users' outgoing data without offering them the possibility of a full opt-out.[28][29][30][31][32] In January 2015, Verizon announced they would give customers the option of opting out, and since April 1, 2015, Verizon has allowed customers to opt-out, either online or by calling a special phone number.[33]

In August 2016, Verizon hired Ronan Dunne, the former head of British provider O2, as the new president of its wireless business.[34]

In September 2016, Comcast confirmed that it planned to launch a mobile service, using Verizon's network as an MVNO, in mid-2017.[35][36]

In February 2017, in the wake of competition from Sprint and T-Mobile, and initiatives to expand the capacity and improve the quality of its network by using macrocells and supporting carrier aggregation, Verizon announced that it would bring back an "unlimited" data plan (subject to throttling in heavy network areas after 22 GB of usage). Verizon's decision not to restrict the bitrate of video services prompted Sprint and T-Mobile to remove similar restrictions from their own plans.[37]

In March 2017, Verizon announced that all their Android phones will have AppFlash, to help users find content and services across different apps.[38] Critics spoke harshly against it.[39]

In May 2018, Former Verizon executive, Miguel Quiroga, launched the pre-paid carrier Visible in Denver Colorado, which Verizon funds and owns.[40][41]

On June 8, 2018, Verizon announced that Hans Vestberg had been picked to become CEO on August 1, 2018.[42]

In August 2018, the fire department of Santa Clara County, California, filed evidence in a lawsuit seeking the reinstatement of net neutrality policies, which accused Verizon of throttling an "unlimited" wireless data plan associated with a vehicle that was being used to coordinate responses to the Mendocino Complex Fire. The department reported that a Verizon Wireless customer service representative insisted that they must upgrade to a higher-cost data plan in order to restore their internet speed. In a statement, Verizon acknowledged that they did not properly explain the terms of their contract, and that the representative did not adhere to a company policy of removing these restrictions during emergency situations.[43]

In 2019, Verizon Wireless services were split between two new divisions: Verizon Consumer and Verizon Business.[44][45]

In 2020 Verizon launched a prepaid mobile phone service named Yahoo! Mobile[46] following acquiring the overall Yahoo! brandname in 2017.[47]

On September 14, 2020 Verizon entered into an agreement to purchase TracFone Wireless which was worth an approximate $6.25 Billion[48]


Network

Verizon Wireless operates a 4G LTE network. اعتبارا من يناير 2020, Verizon claims that 99% of the population of the United States can access their 4G network.[49] However, OpenSignal's crowd sourced data showed 4G coverage of 95.9%.[50]

Before their LTE network was launched, they operated an exclusively CDMA2000 network (the other major CDMA2000 carrier in the US being Sprint). Verizon began its initial tests for the 4G LTE network in 2008[11] in order to move from older-generation mobile communications technologies to the emerging global standard.[51] In December 2010, Verizon Wireless launched a fledgling 4G LTE network in 39 markets.[52] By December 2011, only a year after launch, 200 million Americans were covered with 4G LTE, and 190 markets were covered.[53] اعتبارا من 2016, 98% of the U.S. is covered with LTE, and 92% of all data traffic is on LTE.[54]

In 2012, the service provider bought spectrum from the country's biggest cable companies, including Comcast, and Spectrum (Time Warner Cable and Bright House Networks at the time) to improve its data network across the U.S.[55] The new capacity allowed Verizon to launch what it calls XLTE (LTE on Band 4) in 2013, providing more capacity in congested and well-populated markets.[56]

Because 4G LTE is a data-transmitting network, when it launched, Verizon customers' voice calls were still carried over the company's CDMA2000 network,[57] which was developed for 3G cellphones. In September 2014, Verizon launched voice over LTE (VoLTE);[58] this allowed voice calls to transmit via the data-only LTE network. This also allows for simultaneous voice and data services, something that is unavailable on traditional CDMA2000 calls. Along with VoLTE, Verizon also announced support for HD Voice, which provides higher quality audio for VoLTE calls, and native Video Calling for Android phones. In March 2016, Verizon enabled support for Wi-Fi Calling, which allows calls to be placed over a Wi-Fi network. اعتبارا من أغسطس 2015, nearly 4 million of Verizon's 103.7 million subscribers used VoLTE.[58] In 2019, Verizon announced that they plan to shut down their CDMA2000 network by the end of 2020, making VoLTE the only way to make calls on their network.[59]

A report by RootMetrics on carrier performance in the second half of 2020 ranked Verizon's network as the best in overall national performance, network reliability, network speed, data performance and call performance.[8] Verizon Wireless and AT&T tied for first in text performance.[8]

In September 2015, Verizon's chief information and technology architect Roger Gurnani stated that Verizon was planning to trial a 5G wireless network within 12 months, with "some level of commercial deployment" by 2017.[11] In late-August 2016, Verizon officially announced that it had rolled out LTE Advanced services in 461 markets. The company promoted that the technology would allow at least 50% higher LTE data speeds on supported devices.[60]

By the end of 2019, Verizon had launched 5G service in 30 cities across the U.S.[61] Verizon's 5G network is deployed on millimeter wave spectrum (mmWave).[62] While fast, the high-band spectrum Verizon uses has limited range and high penetration loss.[63][64]

In October of 2020, Verizon launched its low-band Nationwide 5G service in multiple cities across the United States, and in December of 2020, expanded Nationwide 5G coverage to "over 230 million people".[65]

Verizon intended to retired its 2G and 3G CDMA network in favor of 4G LTE, 5G UWB, and Low-Band Nationwide 5G on January 1st, 2021, but made a last minute decision to “indefinitely” halt the retirement.[66] They later confirmed that the CDMA network will be retired on December 31, 2022.[67] Verizon customers using a CDMA-only device, or a 4G LTE device that does not support HD Voice are required to upgrade to a newer device in order to continue using the network once the network is retired.

Apps

Verizon Wireless offers certain applications and services that are exclusive to its subscribers. Many of these apps are pre-loaded on Verizon devices—primarily Android smartphones. The company has received criticism for this practice, as users and critics have viewed the applications to be "bloatware" that are sometimes redundant to applications already included with the device's operating system.[77][78][79]

The NFL Mobile app allows Verizon Wireless subscribers to stream National Football League games and NFL Network on their devices. While previously a subscription-based service, NFL Mobile was made free to all subscribers beginning in the 2015 NFL season. As part of an exclusivity agreement with the NFL, only Verizon Wireless subscribers could stream NFL telecasts to devices with screens 7 inches (18 cm) or less in size. This contract ended after the 2017 NFL season;[80][81][82][83] Verizon agreed to a new five-year, non-exclusive digital rights agreement, which removes the device class exclusivity, and focuses more upon distributing its streams and other enhanced digital content via its portfolio of internet media brands, rather than being exclusive to Verizon Wireless subscribers.[84][80]

As part of a deal that also granted the carrier title sponsorship of the series, Verizon subscribers also have access to exclusive streaming content within the official IndyCar Series app.[85]

The My Verizon app is used for account management, including checking usage statistics and managing the user's service plan and account features.[86][87][88] Verizon Cloud, which allows photos, videos, contacts, messages and call logs to be synchronized online, was released in April 2013 initially for Android phones,[89] followed the next month by a launch for iOS.[89][90] Verizon Messages, otherwise known as Message+, is an alternative text messaging app that additionally allows messages to be synchronized between multiple devices.[91] VZ Navigator is a subscription-based maps and navigation service which provides turn-by-turn navigation, crowdsourced traffic data, weather, events and entertainment listings, gas prices, roadside assistance, 2D and 3D views.[92] The Verizon Support & Protection app provides technical support services, lost device location, and on Android, antivirus functionality.[93]

Verizon Family Locator is a subscription-based service and app can be used to track the locations of family members on a map for up to 10 devices.[94][95] Verizon Family Base allows parents to restrict when and how their children use their phones, view their children's contacts and lock the devices.[95][96] Verizon also offers the GizmoPal, a wristband-worn phone for children that is restricted to only placing or receiving calls from one of two designated caregivers, and has GPS tracking.[97][98]

Other Verizon Wireless apps include Field Force Manager, which allows employers to manage employees with GPS, management timesheets and oversee travel,[99] Visual Voice Mail[100] and Roadside Assistance.[101][102]

The LTE in Rural America Program (or LRA program), introduced in May 2010, covers 2.7 million potential users over 225,000 square miles (580,000 km2) in 169 rural counties.[10] Under this program, partners lease spectrum from Verizon Wireless and connect to the company's network, and Verizon provides technical support and resources to help the rural wireless company build out its own 4G LTE network. The program extends the footprint of 4G LTE coverage for both the rural carrier and Verizon, as customers can take advantage of both networks.[110] اعتبارا من 2015, all LRA members have fully rolled out their 4G LTE networks.
