Broad, dedicated channels, ideally 50MHz or more comprehensive, are required for 5G to provide a user experience that is considerably superior to 4G. The frequency that could save 5G is C-band, which is where it comes in.
After months of conflict with the airlines and FAA, AT&T and Verizon activated their C-band 5G networks. Knock on wood, so far, there are no significant flight interruptions or threats to aviation safety.
After two years of "nationwide 5G" networks from AT&T and Verizon feeling a lot like 4G, C-band could eventually significantly increase speeds. What are the C-band and 5G？ What about a C-band phone? Do you need to be afraid of C-bands? Let's discuss it here!
The 4GHz to 8GHz frequency range of the electromagnetic spectrum, known as the C-band, is reserved for satellite communications. C-band satellite antennas are widely employed in parts of the world where signals can be weakened by heavy rain or other severe weather-related situations. Typically, C-band satellite antennas are between 1.8 and 2.4 meters in length. Although C-band satellite communications need larger antennas and are mainly utilized in Asia, Africa, and Latin America, they are less susceptible to rain attenuation.
Functions of C-Band
- Re-establishing communication channels and allowing for humanitarian relief: When the public needs it most, C-band enables emergency support. When a crisis occurs and the terrestrial infrastructure is disrupted, current information is essential for people looking for help and organizing relief operations. In these situations, C-band satellite connectivity is vital to launching communications services.
- Enhancing community life: Most NGOs and humanitarian organizations use C-band as their primary form of communication for e-learning and e-health. One of the most valuable capabilities of satellite communication is empowering distant populations and providing them with access to healthcare and educational opportunities.
- Assisting companies: The commercial maritime sector, the oil and gas industry, and land-based VSAT applications like mobile backhaul services across challenging terrain and remote areas all rely significantly on C-band for their critical communication links, which have the highest availability.
- Broadcasting on a large number of channels: Hundreds of millions of households rely on C-band for TV programming due to its strong endurance to severe rain, especially in tropical regions like Latin America, Africa, and Asia. More than 1,300 TV channels are transmitted in Latin America using the C-band, also used to distribute TV content to 140 million people in Africa and most TV viewers in Indonesia and India. 115 of the 145 C-band satellites currently in operation are utilized for broadcasting. C-band feeds terrestrial transmission networks, supplies programming to cable head-ends, and delivers DTH services in some rural locations, whether for live sports, news, public events, or international programs.
- Providing weather predictions: The government can share operationally and quickly crucial meteorological data with the public, allowing for early warning of dangerous weather events. If adequate planning is done to evacuate people, thousands of lives could be saved.
Features of C-Band
- C band's frequency is 4103, 3096, and 3085. It only has four digits.
- The C band operates between 3.7 and 4.2 GHz (or 3700 to 4200 MHz).
- Although a frequency with H or V can also be C-Band. A C-band frequency typically has a polarity of L or R, and due to the low frequencies, C-band waves have longer wavelengths.
- As a reminder, a Mesh dish cannot be used with a KU Band frequency and LNB. Here, a C-Band is required.
- Given that we are discussing longer wavelengths, a larger dish is needed to receive these frequencies.
- C band frequencies are received using prime focus dishes.
Therefore, to receive C-band frequencies, a C-band LNB is required. The most petite Prime focus dish that is obtainable commercially measures 1.8 meters.
Benefits of C-Band
- On phones, C-band can give fast rates of up to 100 Mbps.
- Long-range C-band communication is possible without a lot of cell towers.
- Telecom businesses have access to a large amount of C-band spectrum for wireless applications.
Here's the comparison between C-Band and other bands:
- L-Band: The radio spectrum's operating frequency range of 1-2 GHz is referred to as the L band, and the L band's wavelength range is 30–15 cm. The L band is one of the leading operating bands used by many applications, including radars, GPS, radio, telecommunications, and aircraft surveillance. Due to its low frequency and limited bandwidth, the L band is the most widely used since it is the simplest to construct and requires less expensive and complex equipment. L-band satellite stabilization systems are the simplest to install. L-band requires less expensive and sophisticated RF equipment to handle, and because it has a greater beam width, the pointing precision of the antenna is not as critical as it is for higher bands. 1-2 GHz low-frequency range.
- C-Band: Typically, the C-band (4 to 8 GHz) transmits at about 6 GHz and receives at about 4 GHz. Large (2.4–3.7 meter) antennas are used. The C band is a lower range frequency better suited to voice and ISP requirements. A signal can be picked up on considerably smaller dishes since the signal intensity in spot beam zones of the Ku band is often significantly higher (antennas).
1. Is C-Band only for 5G?
The C-band is located in the middle of the 2.4GHz and 5GHz Wi-Fi channels. It is incredibly close to and slightly above the 2.6GHz band that Clearwire, Sprint, and later T-Mobile utilized for 4G beginning in 2007 and is presently being used by T-Mobile for mid-band 5G.
2. What does that mean for the future of 5G?
When you ask the typical individual what they know about 5G technology, the first thing that comes to mind is probably anything related to cell phone technology. And if you take into account how 5G was deployed so far in 2019, you might not be too far off. 5G is a faster successor technology to 4G LTE.
However, the 5G scenario in the next two to three years will be very different from what 5G offers now, how it's deployed, and what it currently looks like. To use a cliché, 5G NR (New Radio) technology is positioned as "disruptive".
However, this next generation of wireless network technology will also enable a wide range of sectors and uses, and it's likely to inspire brand-new use cases.
3. In recent years, 5G is always mentioned by people. What does 5G exactly mean?
The fifth-generation (5G) technological standard for broadband cellular networks, which cellular phone providers started rolling out globally in 2019, is the anticipated replacement for the 4G networks that connect most modern cell phones.
Under this circumstance, you may want to know how to quickly transfer large files over the network.
4. Relationship between C-Band and 5G, or C-Band, 5G and C-Band spectrum.
Our mobile devices can receive internet data from 5G using a variety of radio bands. The millimeter-wave spectrum (24–47 GHz), the much-hyped 5G technology that can transmit gigabit speeds over close lines of sight, lies lower on the radio dial than C-band. C-band, on the other hand, has a greater frequency than low-band 5G (600 MHz–1 GHz), which is capable of speeds and ranges comparable to those of 4G.
C-band, which occupies the middle of the electromagnetic spectrum, falls between mm-wave and low-band, combining quicker speeds with greater range.
5. Why is the C-Band so important?
To get permission to use a portion of this highly sought-after radio spectrum in their 5G networks, AT&T, Verizon, T-Mobile, and a few other US telecom corporations have jointly spent more than $95 billion. The federal government has approved the deployment of the C-band, starting in many American cities in January 2022.
Mobile internet connectivity is offered by wireless providers using electromagnetic spectrum radio waves. The electromagnetic spectrum used for 5G networks also includes the C-band, which, by federal requirements, refers to the frequency range of 3.7–3.98 GHz. This is near the bottom of the C-band spectrum, which has been predominantly utilized since the 1970s for satellite TV broadcasts and distribution.
When we transfer data to mobile devices, 5G uses a variety of radio frequencies. Compared to the millimeter-wave spectrum (24–47 GHz), the much-hyped kind of 5G that can deliver gigabit speeds across close, line-of-sight distances, C-band is lower on the radio dial. Conversely, C-band has a greater frequency than the low-band 5G (600 MHz–1 GHz), which is comparable to 4G in terms of speed and range.
Due to its mid-spectrum location, C-band strikes the ideal balance between mm-wave and low-band, combining higher speeds with greater range.
The two primary cell carriers now deploying C-band 5G are Verizon and AT&T. Therefore, you're OK to go if you have a cell phone plan with either. Of course, to access any C-band networks, you'll also need a 5G phone with that functionality.
Currently, 46 major cities have C-band 5G service, covering 60% of the US population. Although Verizon and AT&T still need to expand their cell sites to guarantee C-band coverage in all of these locations, it will be much more widespread starting in 2022.
Beginning in December 2023, 53 significant additional markets will have access to the second chunk of the C-band spectrum. That includes a considerable portion of T-C-band Mobile's spectrum, which has been devoted to developing lower-band, significantly slower versions of 5G.
The locations where C-band 5G will be accessible as of January 2022 are listed by Allnet Insights & Analytics. The areas where C-band will be made available starting in December 2023 are also listed.
