Cell Frequency: At&T's Network In Aromas, Ca

AT&T's mobile network in the United States is known for its reliability and extensive coverage. The company has discontinued its 2G and 3G networks in recent years, focusing on 4G LTE and 5G technologies. AT&T's 4G LTE network in the US utilises bands 2, 4, 5, 12, 14, 17, 29, 30, and 66. Band 17 in the 700MHz range is the company's primary band, with band 12 added in 2017 to meet FCC requirements. These two bands are now commonly referred to as one entity (band 12) and form the backbone of the LTE network.

AT&T's 5G network in the US operates on 6 5G NR bands, including 5G NR N77 (3700 MHz), a mid-band spectrum added in 2021, and 5G NR N260 (mmWave 39 GHz), a high-band spectrum offering the fastest speeds on AT&T's 5G network.

AT&T's 4G LTE network

Each band serves a specific purpose and is deployed in different areas across the country. For example, Band 2 is used in densely populated areas to offload traffic and provide higher capacity, while Band 5 is beneficial for both rural and urban environments due to its wide coverage and good building penetration.

AT&T has been continuously investing in its 4G LTE network, upgrading existing LTE networks to support LTE Advanced and LTE Advanced Pro features, marketed as "5G Evolution" (5G E). The company has also been working towards repurposing the spectrum previously used for 3G to improve its 4G LTE network, which required customers to upgrade to newer devices that support more advanced networks.

The combination of multiple bands and continuous upgrades ensures that AT&T's 4G LTE network provides reliable and fast connections to its customers across the United States.

Band 12/17 (700MHz)

The 700MHz band was previously used by television stations for analog broadcasts. In 2010, Verizon Wireless used the upper band of the 700MHz spectrum to deploy their LTE network.

AT&T's 4G LTE network also uses Band 12 and Band 17. These bands are used in conjunction with other bands such as Band 4/66 and Band 2.

The use of cellular frequencies is regulated by the Federal Communications Commission (FCC) in the United States. Companies must compete for the right to license parts of the radio spectrum in spectrum auctions.

Band 14 (700MHz)

AT&T acquired Band 14 from FirstNet, and it will be deployed in states that opt into the FirstNet service. This band is reserved for a federally-funded public safety channel, providing a vital service for first responders and emergency services.

The 700 MHz range, which includes Band 14, has been the backbone of 4G LTE coverage in the United States. It offers a good balance between capacity, density, and penetration/range, making it a popular choice for LTE deployments. The lower frequencies in this range can travel far and penetrate obstructions well, making them ideal for rural and remote areas.

AT&T's use of Band 14 demonstrates its commitment to providing reliable and extensive coverage across the country, especially in less populated regions. By utilising this frequency band, AT&T ensures that its customers in rural and remote locations, such as Aromas, CA, can stay connected and access mobile services.

In addition to Band 14, AT&T also employs other frequency bands, such as Band 2, Band 4, Band 5, and Band 12/17, to deliver its 4G LTE services. These bands, in combination with Band 14, contribute to AT&T's comprehensive mobile network, known for its reliability and wide coverage across the United States.

Band 29 (700MHz)

AT&T uses Band 29 to enhance download speeds, and it is deployed in most areas. Some lucky markets on the East and West Coasts have 10 MHz of this spectrum band.

Band 29 is part of the 700 MHz wireless spectrum, which was previously used by television stations' analog broadcasts. In 2008, Verizon Wireless and AT&T Mobility won the majority of the available spectrum.

The 700 MHz band is ideal for rural and remote areas as it can travel far and penetrate obstructions well.

Band 30 (WCS 2300MHz)

Band 30, also known as WCS 2300MHz, is a 4G LTE network frequency band. LTE (Long-Term Evolution) telecommunications networks use several frequency bands with associated bandwidths. LTE is designed to work across a number of frequency bands, ranging from 450 MHz up to 3.8 GHz.

LTE Band 30 is defined as follows: 2305-2315 UL / 2350-2360 DL. This is a frequency-division duplex (FDD) band, meaning it consists of two frequencies separated by a guard band to prevent interference. One band is used to send information to a cell tower (uplink), and the other is used to receive information from a cell tower (downlink).

The available hardware for Band 30 includes the CableFree LTE Base Station, CableFree Emerald LTE, UE Terminals, CableFree Outdoor LTE CPE, CableFree Desktop LTE CPE, and CableFree MiFi Handheld CPE.

LTE Band 30 is just one of the many cellular frequency bands that AT&T uses to provide its services. These bands allow AT&T customers to make calls, send text messages, stream videos, and browse the web.

Cellular frequencies are allocated by the US Federal Communications Commission (FCC), which divides the US geographically into areas that companies then compete to license. Different cellular companies in the same region may use different levels of cellular technology and different parts of the radio spectrum.

AT&T offers a range of internet services in Aromas, CA, including AT&T Fiber, which provides equal upload and download speeds and allows for multiple devices to be connected throughout the home.
