\section{Capability Gap Addressed}

Current tactical networks are vulnerable to centralized node loss, EW targeting, and vendor lock-in, as observed in recent contested environments.

\textbf{RLFHL} provides a low-signature, attrition-tolerant, IP-based mesh backbone to restore platoon-to-company level connectivity when traditional systems fail.

\section{Product Description}

RLFHL is a portable Wi-Fi HaLow (IEEE 802.11ah) mesh network providing secure IP transport for messages, telemetry, images, and opportunistic video. The system is designed to operate where traditional tactical radios and centralized command networks fail.

RLFHL prioritizes \textbf{survivability, simplicity, and manufacturability} over peak throughput. It deliberately avoids proprietary waveforms and closed ecosystems in favor of open standards and crypto agility.

\subsection{RLFHL Tactical Wi-Fi HaLow MESH Network}
Combining portable gateway mobility with robust access point capabilities

\subsubsection{Portable Gateway Features (RLFHL-UM)}
\begin{itemize}
	\item \textbf{Plug-and-Play, Zero Configuration:} No setup required, offering immediate access to wireless internet.
	\item \textbf{Energy Efficiency:} Wi-Fi HaLow ensures low power consumption, excellent signal penetration, and energy efficiency, all while reducing costs and environmental impact.
	\item \textbf{USB Power Bank Support:} A wearable, convenient solution. A standard power bank can keep the RLFHL operational for up to 8 hours.
	\item \textbf{Seamless On-the-Go Connectivity:} Lightweight, convenient wearable devices, combined with WiFi HaLow's long-range connectivity, provide wireless networking anytime, anywhere.
\end{itemize}

\subsubsection{Access Point Features (RLFHL-AP)}
\begin{itemize}
	\item \textbf{Versatile Connectivity:} Offers diverse connectivity options, eliminating the need for unnecessary hubs. Customize and expand your wireless network with unparalleled flexibility.
	\item \textbf{High Device Capacity:} Supports over 8,000 stable connections, four times the capacity of traditional Wi-Fi access points, thanks to innovative star network topology.
	\item \textbf{Long-Range Communication:} Pushes Wi-Fi boundaries, extending connectivity farther than ever before, exceeding 1 km per hop.
	\item \textbf{Robust Data Transmission:} Achieves reliable 150 Kbps data rates for distances over 1 kilometer, coupled with high-speed video streaming capabilities for shorter ranges.
	\item \textbf{Exceptional Signal Penetration:} Excels in cutting through barriers, providing tenfold improved signal penetration compared to standard Wi-Fi frequencies, ensuring strong and consistent connectivity.
\end{itemize}

\textbf{Unified Solution:}

RLFHL integrates both portable gateway and access point capabilities into a single, cohesive system designed for tactical edge communications.

\subsubsection{Graceful Degradation}
Maintains command connectivity even when bandwidth drops to 150 kbps under EW pressure.

\subsubsection{Attrition Tolerant}
Network survives loss of 30--40\% of nodes through self-healing mesh topology.

\subsubsection{Low Observability}
Sub-1 GHz, adaptive duty cycle reduces RF signature by 60--80\% vs typical tactical radios.
