PORTA2030 deploys porta-pack, a mobile network unit that builds on a wifi harddrive (WL-HDD2.5) for multi-faceted transmission. Installed with a 1GB flashcard and programmed in open source codes, the porta-pack functions as a portable data sensing-storage-tranmission unit. A webcam streams images live while an LCD mini-terminal with 4 click action push buttons serves as basic communicative device. The urgency signals triggered by the sensors set in public space further commands porta-porters’ collective action.





PORTA-net uses OLSR protocol (Optimised Link State Routing) to create a single unified wifi network. The vast majority of wireless networks comprise of lots of WiFi antennas (nodes). Each antenna offers wifi access within its range. . Move out of range and you'll have to connect to the next one, and then the next one and so on. Going between the ranges, one loses connection. PORTA-net links each node in constant communication with every other node it can see in the network. Each node has an awareness of its neighbours and what they all can see - they continually exchange network information.

PORTA2030's 10 porta-pack is each assigned a fixed IP address (i.e. 192.168.22.101). When porta-porters move around in the PORTA-net wifi zone, the network shifts its routing to take in stronger signal for connectivity. The inter-communication of portersê signal sending and urgent calling relies on such a dynamic and adaptive PORTA-net.
