Event A3 (Loveren Hysteresis)
Geopolitical sovereignty in the 21st century is no longer a fixed geometric abstraction established by historical treaties, but an elastic, volatile gradient dictated by corporate telecommunications infrastructure and signal hysteresis.
Autonomous cart painting the fluctuating LTE hysteresis border over historical treaty lines. · motion: jittering laterally across the rigid white crosses to chase the fluctuating RF boundary
wall text
In the enclave-riddled streets of Baarle-Hertog and Baarle-Nassau, geopolitical boundaries are formally etched as rigid white pavement crosses. This robotic cart interrogates that static geometry by executing 3GPP Event A3 handover protocols in real time, measuring Received Signal Strength Indicator (RSSI) fields between Belgian Proximus and Dutch KPN cell towers. Applying a 3dBm hysteresis threshold, the machine physically charts the fluctuating digital border in yellow spray paint. Rather than respecting 12th-century treaties, the resulting line jitters and drifts with atmospheric noise and corporate RF propagation, exposing how digital sovereignty operates as a volatile, algorithmic gradient across physical space.

anchor facts used
- The municipality consists of 22 distinct Belgian enclaves entirely surrounded by Dutch territory.
- The exact international border is physically painted on streets and floors as a line of white crosses.
- The 'front door rule' dictates that a building's nationality is determined by which side of the border its main entrance lies upon, famously bisecting the front door at Loveren 2 (Belgian #2 / Dutch #19).
mechanism
- Measurement Control and Reporting (3GPP Event A3) — An autonomous wheeled chassis slowly drives along the painted white crosses at Loveren 2, continuously pinging Belgian (Proximus) and Dutch (KPN) LTE network towers to log Received Signal Strength Indicator (RSSI) metrics.
1. Network Discovery - Hysteresis Margin Filtering — The onboard controller applies a standard 3dBm hysteresis threshold to the live RSSI data, mathematically refusing to switch its registered nationality based on momentary signal noise caused by passing pedestrians or atmospheric shifts.
2. Handover Evaluation - Break-before-make (Hard Handover) — When the hysteresis threshold is definitively breached, the chassis deliberately drops its current national data connection, entering a momentary, stateless 'dead zone' before authenticating with the neighboring country's network.
3. Execution - Late Path Switch Request — Upon successfully establishing the new IP address on the foreign network, a pneumatic valve triggers, blasting a permanent dot of high-visibility yellow marking chalk onto the cobblestones to map the exact digital border.
4. Completion
lineage
- Julian Oliver, 'Border Bumping' (2012) — Extends Oliver's passive cellular mapping software into an active, autonomous robotic mechanism that physically defaces the historical terrain.
- Francis Alÿs, 'The Green Line' (2004) — Replaces the artist's subjective, poetic walking of a geopolitical boundary with the rigid, algorithmic determinism of telecommunication protocols.
- Eyal Weizman, 'Hollow Land' (2007) — Grounds Weizman's architectural theory of elastic, volumetric sovereignty into a falsifiable, micro-local measurement apparatus operating in real-time.
curatorial qa (machine verdict, unedited)
SCORE 4/5 after 1 attempt(s)
READS: The physical chassis actively overwrites the historical treaty border (white crosses) with an erratic yellow paint trace representing the dynamic RF threshold.
FAILS: The exact moment of LTE network disconnect (the 'dead zone' hard handover) is not visually distinguished from continuous signal tracking during the spray run.
