<h1>ARFHL Open Wi-Fi HaLow Mesh Network</h1>
<p>
A standards-based, sub-GHz wireless mesh networking system designed to form a
secure, infrastructure-independent backbone for messages and moving imagery
in realistic field environments. Built on IEEE 802.11ah to enable long-range,
low-power connectivity without vendor lock-in.
</p>
</div>
</header>

<div class="container">
<h2>Product Overview</h2>
<p>
The ARFHL Open Wi-Fi HaLow Mesh Network is a modular networking system composed of
dual-band Wi-Fi HaLow gateways and portable nodes. It is designed to interconnect
a wide range of IP-based devices — sensors, cameras, handheld terminals, edge
computers — into a resilient mesh without reliance on proprietary waveforms or
closed radio ecosystems.
</p>
<p>
The system prioritizes <strong>operational reach, interoperability, and deployability</strong>
over peak throughput. It is suitable for environments where cellular, fiber, or
fixed infrastructure cannot be assumed.
</p>
<div class="grid">
<div class="card">
<h3>Backbone Philosophy</h3>
<ul>
<li>Open IEEE 802.11ah radio standard</li>
<li>Native IP networking (IPv4 / IPv6)</li>
<li>No vendor-locked waveform or controller</li>
<li>Composable with third-party devices</li>
</ul>
</div>
<div class="card">
<h3>Supported Traffic</h3>
<ul>
<li>Secure messaging and telemetry</li>
<li>Moving images (video streams or buffered clips)</li>
<li>Sensor and control traffic</li>
<li>Store-and-forward under constrained links</li>
</ul>
</div>
<div class="card">
<h3>Topology</h3>
<ul>
<li>Star and relay-based mesh</li>
<li>Self-forming and self-healing</li>
<li>Portable, fixed, and mixed deployments</li>
</ul>

<h2>Typical Deployment Scenarios</h2>
<div class="grid">
<div class="card">
<h3>Forward / Remote Sites</h3>
<p>
Establishes a local wireless backbone connecting sensors, cameras,
and command terminals where no backhaul exists or infrastructure
is degraded.
</p>
</div>
<div class="card">
<h3>Mobile Teams and Assets</h3>
<p>
Wearable or vehicle-mounted ARFHL-UM nodes extend the mesh dynamically,
maintaining message and image flow as teams move.
</p>
</div>
<div class="card">
<h3>Temporary Operations</h3>
<p>
Rapid deployment for exercises, disaster response, or temporary
installations without permanent spectrum or infrastructure commitments.

<h2>Security Model</h2>
<p>
Security is based on open, auditable mechanisms rather than proprietary obscurity.
The system supports current best-practice encryption while allowing algorithm
agility for post-quantum transition.
</p>
<ul>
<li>WPA3 link-layer encryption and mutual authentication</li>
<li>Certificate-based device identity and access control</li>
<li>IP-layer security overlays independent of radio hardware</li>
<li>Post-quantum readiness via hybrid key exchange and cryptographic agility</li>
</ul>
<p>
The system does not claim inherent LPI/LPD characteristics. Emission control and
spectrum discipline remain operational considerations.
