Elevate Business Connectivity with 5G
The SureCall SpeedLink 5G is purpose-built to extend 5G C-Band coverage in commercial buildings, overcoming metal roofs, cement walls, e-glass windows, and other obstacles that interfere with next-gen connectivity.


Simple Setup. Serious Boost.
SISO architecture eliminates the need for complex antenna setups, making it easy and cost-effective to install. It effectively closes coverage gaps and enhances data speeds up to 500 Mbps, keeping operations running smoothly.
Swift 5G Without Delays
As the only C-Band signal booster approved by Verizon, the SpeedLink 5G SISO is ready for use with Verizon’s Ultra-Wideband (UWB) network. FCC-certified and requiring no fiber backhaul, it’s built for rapid deployment in office, enterprise, and commercial spaces.


Control Your Boost with Ease
SureCall’s Cloud platform allows easy management and control of the SpeedLink 5G C-Band Signal Booster from anywhere, ensuring optimal operation and enabling swift troubleshooting if needed.
The SpeedLink 5G SISO is SureCall’s C-Band signal booster, designed to work with mid-band frequencies 3.70 to 3.84 GHz. It helps bypass signal-blocking obstacles (metal roofs, cement walls, e-glass windows, etc.) and transform 5G connectivity in office, enterprise, and commercial spaces.
With up to 75 dB gain and up to 28.5 dBm uplink, it strengthens communication with cell sites and delivers robust 5G C-Band coverage up to 50,000 sq ft. For wideband coverage, it can be installed in tandem with a 4G/LTE signal booster.
Its SISO architecture makes installation much easier and more cost-effective than with a MIMO unit. Mobile phones, cellular routers, POS systems, and all other devices that keep your business running smoothly can expect speeds up to 500 Mbps.
Obtaining special approvals to deploy is not necessary. FCC-certified and Verizon-approved right out of the box, the SpeedLink 5G SISO is ready for immediate deployment without needing a fiber backhaul. Via the SureCall Cloud platform, integrators and IoT personnel can remotely monitor and manage performance for optimal operation.

What is so Special About 5G C-Band?
There are three flavors of < a href="/blog/5g-migration-what-you-need-to-know/">5G, each utilizing different frequency bands.
- Low-Band 5G: frequencies have the farthest reach. Speed is comparable to 4G.
- High-Band 5G: offers blazing-fast speeds and insane capacity. However, the tradeoff is range.
- Mid-Band 5G, especially C-Band: is considered to be the “Goldilocks” of the 5G spectrum. It offers a perfect blend of speed, range, and capacity.
As 5G technology continues to be rolled out, C-Band will also support Voice-over-New-Radio 5G (VoNR-5G).
See our guide on C-Band for more information.
How Does the SISO SpeedLink 5G C-Band Signal Booster Work?
The SpeedLink 5G consists of three core components:
- A donor antenna, typically mounted on the roof, captures existing C-Band signals from nearby cell towers.
- The amplifier boosts those signals, improving signal strength and reliability.
- Indoor antennas, placed throughout the building, distribute amplified 5G signals to targeted areas.
Bi-directional, it also strengthens communication with 5G C-Band base stations. The results include increased 5G C-Band coverage and faster data speeds.
What’s the Difference Between the SpeedLink 5G SISO and SpeedLink 5G MIMO?
The SISO model uses a single input/output path, making it significantly easier to install and more cost-effective – ideal for straightforward deployments. The < href="/surecall-speedlink-5g-c-band-commercial-signal-booster/">MIMO SpeedLink 5G has a dedicated input and output path. This allows it to provide up to double the data speeds of the SISO model. However, it requires a more complex setup. It’s best for data-intensive applications.
What Cellular Carriers Does the SISO SpeedLink 5G C-Band Booster Work With?
It’s only compatible with Verizon.
What Frequencies Does the SpeedLink C-Band Booster Support?
It supports C-Band frequencies 3.70 to 3.85 GHz. For wideband coverage, it can be used alongside a 4G cell phone booster.
What’s the Benefit of the SpeedLink 5G Being Verizon Approved?
Other C-Band signal boosters require carrier approval for deployment. Obtaining approval can take months. Verizon approved right out of the box, the SISO SpeedLink 5G allows immediate deployment. You can power your business with 5G connectivity without delay.
How is Remote Monitoring Handled?
Remote monitoring is done through the SureCall Cloud app.
