Product Description

Features of the SureCall SpeedLink

  • The SureCall SpeedLink amplifies Verizon’s 3.7–3.84 GHz C-band cellular network. It’s the only C-band booster approved by Verizon for use on their 5G Ultra Wideband (UWB) network—no licensing or broadcast agreement required!
  • An optional Wideband Upgrade Kit unlocks coverage for AT&T and T-Mobile C-band (3.7–3.98 GHz).*
  • C-band (band 77) provides faster cellular data speeds—up to 1 Gbps—with greater network capacity for more phones and cellular devices.
  • A SpeedLink DAS system extends the reach of C-band 5G inside large buildings, filling coverage gaps and delivering ultra-fast data speeds without the need for a fiber backhaul. The SpeedLink overcomes natural and man-made obstructions—cement walls, e-glass windows, metal roofs, etc.—that block signal between towers and cellular devices.
  • With a minimum of 300 Mbps C-band speed outside, the SpeedLine can provide up to 50,000 square feet of indoor coverage.
  • Includes remote monitoring to manage the booster system on- or off-site. The SureCall Cloud™ web interface indicates signal strength and booster performance in real time for help with initial installation and ongoing troubleshooting. (Learn more about SureCall Cloud.)
  • The SpeedLink’s IP54-ratedexternal link icon case protects against dust and water intrusion.
  • Industry-leading design, installation, and lifetime support from Powerful Signal, the leader in improved in-building cellular signal.

Wideband Upgrade Kit available at additional cost. AT&T and T-Mobile C-band coverage requires written carrier broadcast agreements.

SureCall SpeedLink 5G C-band cellular booster A SureCall SpeedLink system amplifies and distributes high-speed C-band 5G cellular signal coverage throughout your building.

Integrated SureCall Cloud service

The SureCall SpeedLink includes SureCall Cloud service that provides remote monitoring and administration tools for I.T. departments and system integrators anywhere, without having access to the building’s Ethernet or WiFi network.

With the SureCall Cloud you can remotely log on to the SpeedLink booster through your phone, computer, tablet, or other device with a web browser. Once logged in, you can:

  • Monitor the booster’s uplink and downlink gain and power and user capacity levels in real time and see historical reports.
  • Manually adjust uplink and downlink gain, power, and attenuation limits for each band of cellular frequency (if needed).
  • Remotely power cycle (reboot) the system.

Remote monitoring is available through a cellular connection and requires a SIM card.

A one-year SureCall Cloud subscription is included with the purchase of the SpeedLink and is billed annually thereafter. For subscription pricing information, please call Powerful Signal at 435-634-6800 or contact us online.

Optional plenum air coax cable upgrade

The SureCall SpeedLink 5G system includes 400-type coax cable to connect the amplifier to the inside antennas. If your building requires fire-rated cable in plenum spacesexternal link icon, please ask us about upgrading to ½-inch plenum air coax. Plenum cable fully meets state and federal building codes.

Plenum cable also has nearly half the signal loss per foot of cable compared to 400-type coax cable, delivering stronger signal from the SureCall amplifier to your phones and other cellular devices.

(Plenum air cable is available at additional cost. Call Powerful Signal at 435-634-6800 for details.)
