Frequently Asked Questions:
What is Cel-Fi by Nextivity?
Cel-Fi is Nextivity’s brand of self-configuring, environmentally aware, indoor coverage solutions. Each Cel-Fi system consists of two units. The Network Unit is placed in the area where the strongest native signal can be received from the carrier network (signal levels as low as -120 dBm are acceptable). The Network Unit comprises a transmitter and receiver which communicates with the cell tower. The Coverage Unit is placed in the center of the home, communicates wirelessly with the Network Unit and “lights up” the interior of the house with significantly enhanced signal levels, thus enabling better quality calls and greater data throughput.
What makes Cel-Fi so different from other signal boosters?
Cel-Fi is a smart signal booster. That means it relies on intelligent, self-organizing algorithms to ensure you benefit from the largest area of coverage without compromising or interfering with your mobile operator’s networks or impeding other subscribers’ signals. Cel-Fi does not require any new equipment, any configuring, or any changes to existing network infrastructure or mobile devices. It is also a plug and play device, which means that there is no need for professional installation, no drilling, and no cables. In addition, Cel-Fi has been recognized for its superior design and effectiveness and is the only consumer booster authorized for use by the communications commissions in Australia and the United Kingdom, and the only Smart Booster designed to meet the new FCC Safe Harbor 2 specifications that allow very high gain (very high signal gain is necessary to make low level signals useful in a large coverage area).
What coverage can I expect from a Cel-Fi system?
The radius (half the width) of the coverage bubble is approximately the distance between the Coverage Unit and Network (window) Unit. Here are some examples:
- Radius = 20 meters (66 ft.) for wood framed walls
- Radius is less for concrete interior walls
- Radius can easily exceed 65 meters (200 ft.) for open commercial spaces
Can Cel-Fi boost the signal of multiple cellular networks at once?
Cel-Fi signal boosters are Operator specific, and will only boost one Operator’s channels at a time. Being Operator specific is one of the main reasons that we are network safe and can provide 100 dB of signal gain, and why we are the only signal booster approved by a growing number of Operators.
What technologies does Cel-Fi support (3G? 4G? 5G)?
Cel-Fi system will support 3G(UMTS/WCDMA), 4G (HSPA/HSPA+), LTE, and certain kinds of 5G. Each Cel-Fi system is different. Check your box for a Quick Start Guide, or visit the support section for more specific information about your specific product.
