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 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 centre of the home, communicates wirelessly with the Network Unit and “lights up” the house’s interior with significantly enhanced signal levels, thus enabling better quality calls and greater data throughput.
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 and configuring or 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 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. It is 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).
Yes, Cel-Fi smart signal boosters can support both voice and data simultaneously. Note that Cel-Fi RS1 and RS2 models do not support LTE.
Every installation is different. The differences depend on the “path loss” between the two units. Every obstacle in the line of sight means that the Coverage Unit and the Network Unit will have to be closer together. The cleaner the line of sight, the further apart they can be placed. The more walls, doors, or refrigerators (obstacles), the closer their units will have to be in the direct line of sight. The average distance for a typical construction home is 18 meters. However, the placement can be as little as 6 meters or much as 36 meters apart.
The radius (half the width) of the coverage bubble is approximately the distance between the Coverage Unit and the 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
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 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.
System gain is critical to a booster’s performance because it tells us how much a signal may be improved and how beneficial the boosted signal can be. Example: If you have a low-level signal such as -90 dBm per carrier, adding 100 dB of System Gain gives +10 dBm per carrier, covering a large area. In contrast, adding only 70 dB of gain would only give -20 dBm of signal per carrier which would only cover a very small space. Therefore, a booster with a gain of 70 dB would need a powerful donor signal to be of much use, regardless of the stated transmit power that likely is going unused.
In other words, the higher the gain of the booster, the better it will work, even when far away from a base station.
Yes, and for a good reason! Cel-Fi is controlled by and operates as an extension of an operator’s network, allowing Cel-Fi (by the regulatory authority) to boost signals about 1000x more than other solutions. Therefore, covering extensive areas even if the original network signal is weak. And it works very well.
Broad-spectrum repeaters can cause interference and damage to networks, so operators have adopted a strict policy against using these legacy signal boosters on their networks. However, Cel-Fi (the only smart signal booster of its kind) is authorised for use by each carrier and allowed to transmit on their licensed spectrum without ruining things for anyone else.
Cel-Fi system will support 3G(UMTS/WCDMA), 4G (HSPA/HSPA+) and LTE.
