Reliable cellular coverage is more than a convenience—it’s a necessity for both homes and businesses. Many people struggle with dropped calls and slow data speeds due to building materials, remote locations, or distance from cell towers. Nextivity’s Cel-Fi product line has become a trusted solution for these challenges, with the RS1 and RS2 models standing out as popular choices. Both are designed to transform weak signals into strong, stable coverage throughout your space. Choosing between them requires a closer look at their features, performance, and value.

How Do RS1 and RS2 Signal Boosters Work?

Nextivity’s RS1 and RS2 signal boosters are built on a foundation of advanced technology that sets them apart from traditional amplifiers. At the heart of both models is the IntelliBoost processor, a proprietary innovation that intelligently filters and amplifies cellular signals. This technology ensures that only the desired signals are boosted, while unwanted noise is minimized, resulting in clearer calls and more reliable data connections.

Each system uses a two-unit design: a Network Unit (also called a Window Unit) and a Coverage Unit. The Network Unit captures the signal from the nearest cell tower, while the Coverage Unit rebroadcasts the amplified signal inside your home or office. These units communicate wirelessly, eliminating the need for complicated wiring and making installation straightforward. The wireless link operates on UNII bands, which are carefully chosen to avoid interference with Wi-Fi and other household devices.

A key feature of both models is their carrier-specific design. By focusing on a single carrier, these boosters can deliver up to 100 dB of gain—far more than most broadband amplifiers. This approach not only maximizes performance but also ensures compliance with carrier and regulatory requirements, making them a safe and effective choice for improving coverage in even the most challenging environments.

What Networks and Frequencies Do RS1 and RS2 Support?

Network compatibility is a crucial factor when selecting a signal booster. The RS1 was developed primarily for 3G networks, with limited support for early 4G technologies. It operates on specific frequency bands tailored to the carrier version you select, usually focusing on UMTS/WCDMA (3G) bands.

The RS2 takes compatibility a step further by supporting both 3G (UMTS/WCDMA) and 4G (HSPA/HSPA+) networks. However, neither the RS1 nor RS2 supports LTE, which is now the standard for high-speed data. If your main goal is to boost LTE performance, you’ll need to consider newer Cel-Fi models such as the DUO+.

Both the RS1 and RS2 are programmed to work with a single carrier. This specialization allows them to deliver exceptional gain without causing network interference, but it also means you can’t use one device to boost multiple carriers at once. This design choice is intentional, ensuring that each booster operates safely and effectively within the carrier’s network.

Setting Up Your Signal Booster: What to Expect

Installing the RS1 or RS2 is a straightforward process designed for non-technical users. There’s no need for professional installation or special tools. The process begins by placing the Network Unit in a location where it can receive at least a minimal signal—usually near a window or exterior wall. The Coverage Unit is then positioned in the area where you need better coverage.

Both models require a minimum signal strength of about -120 dBm, which is roughly equivalent to one bar of service on most phones. This makes them suitable for areas with weak, but not completely absent, cellular signals. No internet connection or GPS is needed; the boosters work by amplifying whatever signal is available.

The RS2 offers a slightly improved setup experience, with more intuitive indicator lights and a smoother registration process. Both models feature self-configuration, automatically adjusting to changes in network conditions. For especially challenging environments, such as basements, optional external antennas are available for both models (look for versions with the _EXA suffix).

Comparing Coverage and Performance

Coverage area is a major consideration when choosing a signal booster. The effective range of both the RS1 and RS2 depends on the distance between the Network Unit and the Coverage Unit. In typical wooden-framed homes, you can expect a coverage radius of about 20 meters (66 feet) from the Coverage Unit. Buildings with concrete walls will see reduced coverage due to signal attenuation, while open commercial spaces may achieve a radius of up to 65 meters (200 feet) under ideal conditions.

The RS2 generally delivers better performance than the RS1, especially in challenging environments. This improvement is due to advancements in signal processing and distribution algorithms. Both models provide approximately 100 dB of system gain, making them about 1,000 times more powerful than many competing solutions. This high gain allows them to create usable signals from very weak inputs, transforming previously unusable spaces into areas with reliable coverage.

Key Features That Set RS1 and RS2 Apart

Both the RS1 and RS2 offer a range of features designed to make them user-friendly and effective. Some of the standout features include:
