Fresnel Zone / HavenCo (Reed-Solomon)
Extraterritorial data sovereignty is not an absolute legal state, but a physical variable strictly bounded by atmospheric diffraction and the continuous operation of forward error correction algorithms.
Sealand microwave link degrading as a container ship enters the Fresnel zone. · motion: stuttering and violently striking in direct proportion to mathematical packet loss
wall text
HavenCo founded its offshore data haven on Sealand under the premise that legal autonomy could exist off the UK grid. In practice, its microwave line-of-sight link to Felixstowe was vulnerable to physical physics. This piece visualizes extraterritorial sovereignty as a dynamic signal budget. As container vessels penetrate the 10 GHz beam's first Fresnel zone, multipath propagation and diffraction cause heavy packet loss. The video feed stutters and disintegrates in lockstep with real-time Reed-Solomon forward error correction limits. Sovereignty here is not an immutable legal status, but an active mathematical recalculation against maritime interference.

anchor facts used
- Located 12 kilometres off the coast of Suffolk on a 1942 Maunsell Sea Fort (HM Fort Roughs).
- Hosted the unregulated data haven 'HavenCo' starting in 2000.
- Relied entirely on line-of-sight microwave links to the UK mainland due to the physical absence of submarine fibre cables.
mechanism
- Microwave Line-of-Sight (LoS) Propagation — Used not for data transfer, but as a volumetric spatial sensor measuring the interference of the North Sea maritime environment.
1. A continuous 10 GHz microwave link is transmitted across the 12km expanse between Sealand's platform and a mainland receiver in Felixstowe. - Fresnel Zone Clearance and Diffraction Attenuation — Physical maritime traffic and weather events are captured as real-time signal degradation (attenuation).
2. Cargo ships, weather systems, and tidal swells physically penetrate the invisible elliptical boundary of the radio beam, causing signal diffraction and phase shifts. - Reed-Solomon Forward Error Correction (FEC) — The error-correction rate is isolated as a continuous metric of environmental hostility to the data haven's existence.
3. The receiving hardware detects corrupted data frames and mathematically reconstructs the missing bits without requesting retransmission. - Pneumatic Actuation via Pulse-Width Modulation (PWM) — Invisible packet loss and mathematical reconstruction are rendered as concussive, physical impacts echoing across the concrete platform.
4. The instantaneous FEC byte-correction rate controls heavy pneumatic actuators that physically strike the fort's rusted 1942 anti-aircraft gun mounts.
lineage
- Trevor Paglen, 'The Last Pictures' (2012) — Builds on Paglen's materialization of communication infrastructure, shifting focus from orbital longevity to immediate atmospheric precarity.
- Timo Arnall, 'Internet Machine' (2014) — Inverts Arnall's depiction of hyper-controlled, climate-stabilized data centers by exposing the chaotic, weather-dependent vulnerability of HavenCo.
- Claude Shannon, 'A Mathematical Theory of Communication' (1948) — Physically embodies Shannon's concepts of channel capacity and noise, rendering the abstract mathematical fight against entropy as mechanical percussion.

SCORE 4/5 after 2 attempt(s)
READS: The passing cargo ship directly triggering severe signal degradation and digital compression artifacts across the Sealand transmission link.
FAILS: The direct mathematical operation of Reed-Solomon decoding remains an aesthetic glitch rather than explicit visual error telemetry.
