Responders need connectivity the day they arrive: for coordination, registration, payments and safety. A deployable kit of satellite and cellular backhaul, Wi-Fi and mesh, power and security brings a field office or warehouse online within days and keeps it running for as long as the operation lasts. [Plan a deployment](https://observatory.global/contact/deployment/) How it works [Station Builder](https://observatory.global/studio/builder/) **Industry**: Humanitarian **Measurements**: 4 **Sources cited**: 4 1. Humanitarian · Field connectivity for responders Connected on day one Responders need connectivity the day they arrive, for coordination, registration, payments, logistics and their own safety. After a disaster, local networks are often down or overloaded. A deployable kit brings a field office, warehouse or clinic online within days, and keeps it running for as long as the operation lasts. 2. What is measured Links, use, security and power The kit measures itself: availability and capacity of each backhaul link, Wi-Fi coverage and use across offices and warehouses, security events at the gateway and the state of its solar and battery system. Staff see the same status the support team sees. MeasuredLink availability · Capacity · Wi-Fi use · Security events · Power 3. The base node Priority, offline and separated The node caches updates and maps to save satellite capacity, gives coordination and safety calls priority, and keeps local services working offline when links fail, syncing when they return. The gateway separates staff, partner and guest networks, so sensitive data never shares a network with guests. 4. Radio and links Satellite first, then everything else Low-orbit satellite gives broadband on day one where terrestrial networks are down. Cellular is bonded with it where it works, Wi-Fi covers offices and warehouses, and mesh links reach a nearby clinic or warehouse without cables, so the whole compound shares one secured network. LinksSatellite · Public cellular · Wi-Fi · Mesh 5. How it works From a crate to a coordination call A kit arrives at a new field office two days after a cyclone. Staff mount the terminal and access points and power on; the site registers itself and is online within hours. That afternoon the coordination call runs on it, and registration teams start work on a separate, secured network. 6. From order to operation · Order Scope the operation The scope reads the operation's sites, staff numbers, services, expected length, security policy and the shared services already present. Nexus Observatory Inc. returns the kit per site, capacity plan, security design, support and a price per site and per month. [Plan a deployment](https://observatory.global/contact/deployment/) 7. From order to operation · Survey Survey remotely, then on site Sites are first assessed from maps and partner reports, then on arrival: sky view for satellite, cellular coverage, buildings for mesh points, power, and safe places for equipment. Findings are recorded so the next site in the same area deploys faster. 8. From order to operation · Permits Import, licences and security Equipment crosses borders under the relief telecommunications convention where the host country applies it, radio use is notified or licensed, and the agency's security and data protection officers approve the network design. Every approval is kept with the site record. 9. From order to operation · Build Build ready-to-run kits Kits are built and tested with terminals, routers, access points, gateways and nodes configured with the agency's security policy and networks. Nodes are enrolled with their identities, and every kit runs together for a day before it is packed for shipping. [Open the Station Builder](https://observatory.global/studio/builder/) 10. From order to operation · Install Set up in a day Staff or crews unpack the kit, mount the satellite terminal, place access points and mesh points, connect solar power, and power on. The kit registers itself, and the site is online, usually within the first day on site. Crews follow the site safety plan throughout the work. 11. From order to operation · Commission Commission the security Each node proves its identity. Link capacity is measured, Wi-Fi coverage walked, network separation and security policies tested, and emergency calling checked. The site enters service when its tests pass and the security officer signs off. Acceptance is recorded with the owner before handover. 12. From order to operation · Operate Keep the operation connected The operation sees every site's links, capacity, use, power and security events. Capacity shifts to sites in the hardest phase, failed links switch to the second path, and security events reach the agency's team at once. Every alert and action is kept on the record. 13. From order to operation · Maintain Support until the end Remote support handles most faults; spares travel with logistics; software and security updates roll out in rings. When the operation ends, kits are recovered, wiped, refurbished and returned to the stock for the next deployment. Maintenance history stays with each site for its whole life. [Book field services](https://observatory.global/contact/field-service/) 14. Data products For staff, telecom teams and security Field staff and partners receive connectivity; information technology and telecom teams receive link, capacity and power status; security and data protection officers receive security events; coordination bodies and donors receive service reports, each tied to the site and the period.

Operating contextHumanitarian operations depend on shared connectivity services, and the international convention on telecommunications for disaster relief eases the import and use of equipment across borders. Information security is managed to the international standard, and data about affected people is handled under humanitarian data protection guidance. Hazards - No working networks after a disaster - Satellite capacity that is costly and quickly saturated - Power cuts and fuel shortages - Theft of equipment - Sensitive data about affected people exposed on open networks **02** What must be measured ## What, where, how often, and under which rules. Each measurement names where it is taken, how often, and the public standard or regulation behind it. Numbers in the sources column open the cited source below. | Measurement | Where | Cadence | Sources | | --- | --- | --- | --- | | Link availability and capacity | Each backhaul link and the site network | Continuous | 1 | | Wi-Fi coverage and use | Offices, warehouses and common areas | Continuous | 2 | | Security events | The site security gateway | Continuous, events on detection | 23 | | Power state | The kit's solar and battery system | Continuous | 4 | **03** The observation stack ## From one base unit to a network. The same blocks at every scale: instruments and a base node, a site with its radio, a fleet run as one, and a network federated on the open protocol. 1. **01** Base unit A kit: a satellite terminal, a cellular router, a Wi-Fi access point, a security gateway and an edge node in a rugged case.

Radio and links ### Public cellular Cellular is bonded with satellite where it works, to add capacity and a second path. Radio and links ### Wi-Fi Wi-Fi covers offices, warehouses and common areas for staff and partner devices. Radio and links ### Mesh network Mesh links reach nearby buildings and a clinic without cables. Edge computeThe node caches software updates and maps to save satellite capacity, shapes traffic so coordination and safety calls come first, keeps working offline when links fail and syncs when they return, while the gateway separates staff, partner and guest networks. PowerSolar panels and batteries in the kit run the site through power cuts; the kit reports its own power so staff can shed load before it fails. **04** How it works ## From the instrument to the product.

Data products - **Connectivity at every site** Field staff and partners - **Link, capacity and power status** Information technology and telecom teams - **Security events** Security and data protection officers - **Service reports** Coordination bodies and donors Integration - **Agency network** Sites join the agency's own network and identity systems through the security gateway. - **Coordination services** Site status is shared with common connectivity services. - **Asset tracking** Kits are tracked from warehouse to site and back. Exchanged through IEEE 802.11, IPsec, SNMP. **07** Questions buyers ask ## Before you scope it. How fast is a site online? Usually within the first day on site. Is it secure enough for registration data? Networks are separated and secured to the agency's policy. What if satellite capacity runs out? Caching and traffic shaping keep priority services working. Can we reuse kits? Yes. Kits are recovered, wiped and redeployed. **08** Resources ## The sources behind this page. Public standards, regulations and guidance, cited where they apply.
