What is RBF Technology?

RBF, developed by Roombanker, is an exceptional two-way radio protocol that delivers outstanding performance in long-range capabilities, low power consumption, and high-security data transmission. RBF provides a reliable solution for seamless interaction between the Home Security Hub and wireless peripherals.

Kilometer-level Two-way Wireless Communication

The RBF protocol enables the extensive range of up to 3500m, effortlessly covering various scenarios such as apartments, villas, retail stores, and more.

Vast Coverage

The RBF protocol is built upon the Sub-1GHz spectrum and leverages advanced FSK/DSSS modulation technology to achieve wireless communication with an impressive range of up to 3500 meters.

Vast Coverage

Omnidirectional Antenna

The balanced signal strength in all directions provides wider coverage and can resist signal loss caused by obstacles in the transmission path, effortlessly covering complex scenarios.

Automatic Signal Adjustment

Devices with RBF technology can adjust RF transmission power based on signal strength, resulting in lower power consumption, extended battery life, and reduced frequency of battery replacement.

Stable, Secure and Solid Data Transmission

TDMA (Time Division Multiple Access Technology)

In RBF wireless system, peripherals’ working time and wake-up intervals follow strict rules. Peripherals are allowed to alarm only during designated time slots for reporting. All devices synchronize their reporting activities to their respective time slots, thereby minimizing internal system interference.

LBT (Listen Before Talk)

When multiple alarm events are triggered simultaneously, each peripheral will activates the LBT mechanism to checks if the current channel is busy, and either hops to a different frequency or waits for the channel to become idle before transmitting the signal, preventing channel congestion and data loss.

FHSS (Frequency-Hopping Spread Spectrum)

Anti-Jamming: works when meeting continuous interference from an intruder using signals within the same frequency range.

AES-CCM Encryption

The RBF protocol employs AES-CCM data encryption in conjunction with FHSS, rendering the intrusion attempts of attackers futile in terms of interference, signal interception, and replication.

Low Power Consumption

All RBF devices have undergone CE/RED low-power certification tests, with standby power consumption below 2 uA. Just need two AA batteries for a standby lifespan of up to 2 years, significantly reducing maintenance frequency.

Low Power Consumption

OTA Multicast

RBF devices support OTA firmware updates, which features fast transmission speeds and high throughput, allowing for simultaneous firmware transmission and updates across multiple devices.
