What is C-Band?
C-band is a mid-range 5G frequency spectrum from 3.3 to 5.0 GHz. Within this frequency range, band n77 covers 3.3 to 4.2 GHz and major US carriers utilize a portion of n77 spectrum between 3.7 to 3.98 GHz for their cellular broadband networks to expand the availability of 5G technology to mobile users.
The SureCall SpeedLink 5G supports both ‘narrowband’ 3.7 to 3.84 GHz and ‘wideband’ 3.7 to 3.98 GHz of the available C-band frequency spectrum. With SpeedLink 5G, devices have a stronger connection to the network over C-band and users can expect ultra-fast data speeds up to 1 Gbps. C-band will also support Voice-over-New-Radio-5G (VoNR-5G) as that technology is rolled out over each network in the next few years.
What is C-band used for?
C-band 5G spectrum has high capacity and low latency, which means more high-speed data can be transmitted and connect more simultaneous users in an area. This makes it an excellent option for many 5G applications allowing users to stream live video, download movies and TV shows instantly, video-conference in real-time, and take advantage of new gaming and immersive opportunities. 5G wireless connectivity offers businesses a way to seamlessly connect wireless devices such as, point-of-sale systems and mission-critical communications to the network. C-band 5G also supports new and emerging technologies that depend on fast wireless connections to transfer large amounts of data in real-time, such as artificial intelligence, machine learning, and virtual/augmented reality.
SureCall and C-Band
SureCall’s SpeedLink signal booster helps with one of the biggest challenges for C-band 5G networks by providing sufficient coverage and connectivity inside of buildings for cellular users who find themselves outside of 5G range because of natural and man-made obstructions (cement walls, e-glass windows, metal roofs) that block signal between the base station and their mobile device. The advanced SpeedLink system bypasses those obstructions and amplifies the RF signals simultaneously to the users’ devices and back to the base station, providing strong 5G connectivity for users inside signal-challenged buildings.

SureCall C-Band Products
Instantly expand 5G coverage, deliver ultra-fast data speeds up to 1 Gbps, and increase network
capacity inside large buildings with SpeedLink 5G, the ONLY C-band signal booster approved by Verizon
for use on their 5G UWB (Ultra Wideband) network in addition to being FCC-certified for immediate
deployment. With MIMO or SISO compatibility, the flexible design allows it to deploy quickly and
economically inside offices, enterprise buildings, and commercial spaces without the need for fiber
backhaul. The system is also scalable and can be installed in tandem with existing 4G/LTE 5-band booster
systems for full cellular coverage inside the building..
The SpeedLink 5G C-Band Signal Booster ships ‘narrowband’ supporting the 3.70-3.84 GHz and can be
easily and quickly configured to support the ‘wideband’ 3.7-3.98 GHz C-band spectrum, for
futureproofing and the ability to install one system that covers multiple carriers. The upgrade kit
contains all the parts needed to modify the outdoor installation along with remote wideband activation
of the booster to support the additional C-Band frequencies. Kit includes: wideband activation, exterior
MIMO antenna, 2 x 2-way splitters and 8 cable connectors. SC-400 cable sold separately.
What is the difference between C-band and 5G?
C-band is a specific frequency range used to transmit 5G signals. National US carrier networks broadcast 5G signals over three types of frequency band spectrums– low, mid, and high bands. Low-band carries signals cover wider geographic areas while high-band travels shorter distances but are good for fast data speeds and capacity. Mid-band spectrum, where ‘C-band’ resides, is widely viewed as the ‘Goldilocks spectrum’ or ‘sweet spot’ within the available 5G frequencies because it can deliver faster data rates and higher capacity than low band spectrum and c-band signal can travel a greater distance than the high-band spectrum.
How do I get a C-band booster?
SpeedLink 5G (part# SC-5G-CB) is available for purchase and immediate deployment from SureCall’s distribution partners. Please see the list below with our authorized distributors and resellers that offer C-band boosters and accessories.

Calculate your boost with SureCall
We created an adjustable chart that helps installers determine the approximate boost that can be expected after installation. Simply enter the input signal, cable lengths, antennas, and other details from the site survey to produce an estimate. On average, with a minimum of 300 Mbps C-band speed outside, most can expect indoor coverage up to 50,000 sq ft with the standard SpeedLink kit, which ships complete with an outside donor antenna and four indoor server antennas, along with all the splitters and accessories necessary for quick installation. SureCall also offers iBwave design services for buildings over 25,000 sq. ft. for a small fee. Submit your design request at surecall.com/design-service.
How far can C-band travel?
Usable cell distance from 5G towers depends on many environmental factors, including urban or rural surroundings, density of buildings, terrain, and power/frequencies used by the tower. In early field testing, C-band networks vary by location and can go up to 1 mile from each site in an urban area and up to 6 miles in a rural area. So, approximately a half-mile to 1-mile average distance for C-band frequencies is a good estimate for most tower locations.
Does Verizon 5G use C-band?
Yes, all major US Carriers including Verizon own and use a portion of the C-band 5G spectrum, which falls in the 3.7-3.98 GHz frequency range.
What is C-band DOD?
The U.S. Department of Defense (DoD) made 100 megahertz of mid-band spectrum that was once used by the military available to the private sector for 5G technologies. US carriers now have a contiguous mid-band (C-band) spectrum to enable and broadcast their higher-capacity 5G networks.
Who owns the C-band spectrum?
The majority of the 5G C-band ‘n77’ frequency band – which covers approximately 280 megahertz of spectrum between 3.3 and 4.2 GHz – is owned by the ‘Big Three’ carriers, Verizon, AT&T, and T-Mobile. Major US carriers currently utilize a portion of this n77 spectrum between 3.7 to 3.98 GHz which offers an attractive combination of speed and range.
If I have the Verizon C-band booster can I upgrade to also boost AT&T?
Yes! The SpeedLink signal booster ships ‘narrowband’ supporting the Verizon C-band frequency band. The booster can also be remotely configured as ‘wideband’ to support AT&T and/or T-Mobile C-band frequencies for an additional fee. Please follow the steps below to purchase and set up the 'Wideband Upgrade Kit'
