BLACK SKY: No Power. No Internet. No Communications. Think Tigertek.
What happens when the lights go out — and the internet, mobile networks and vital infrastructure fail with them? The BBC's 7 November 2026 report on a possible 'Black Sky' event is a timely reminder that resilience is not just about restoring electricity. It is about preserving critical information and communications when conventional systems are unavailable.
The BBC recalls the December 2015 Lancaster floods, when power was lost to approximately 61,500 people and disruption spread into water supplies, transport, shops and telecommunications. FM radio and traditional copper telephone connections helped people communicate. Today's interconnected world brings enormous advantages, but the incident illustrates how quickly dependent systems can fail together.
NO POWER. NO INTERNET. NO SIGNAL. WHAT HAPPENS TO YOUR DATA?
When an electrical or communications outage hits, a business still needs to know whether temperatures are safe, pressure is maintained, pumps are functioning, assets are secure and conditions are deteriorating. Hospitals, water utilities, food and pharmaceutical cold chains, industrial plants, remote infrastructure and local authorities all depend on timely information. The ability to collect, move and display essential sensor data locally can be critical to informed decisions.
Tigertek's advantage: communications engineering that starts with the real problem
Tigertek specialises in finding practical ways to move sensor data from where it is generated to where it is needed — even when terrain, distance, obstructions, infrastructure or commercial constraints make conventional connectivity unsuitable. Our strengths span specialist radio communications, sensor integration, practical R&D, emerging mesh architectures, multi-protocol bridging and local-display concepts. Rather than assuming a permanent internet connection, we examine the full route from sensor to useful information.
1. Local data, local decisions
A cloud platform is not always the right place for the only copy of operational information. Tigertek's local-display and multi-protocol bridge development points toward architectures in which essential measurements can be available near the equipment, under the customer's control, with optional server, gateway or cloud connectivity when appropriate. Local operation still needs functioning sensors, controllers, displays and a suitable power supply.
2. Radio and mesh: alternative pathways
Properly designed radio networks can connect sensors without relying on a site's broadband connection. Mesh topologies may offer alternative routes around an unavailable node, depending on the radio technology, network layout, power provision and failure conditions. No mesh can overcome every outage, and resilient design requires testing of coverage, redundancy and operating time.
3. Designed for difficult environments
Remote rural sites, mountains, glens, dense urban locations, industrial buildings, underground or obstructed installations and challenging materials can all create communications problems. Tigertek's approach combines experience and R&D to select and integrate appropriate technologies rather than forcing every customer into a one-size-fits-all system.
4. Less unnecessary infrastructure
Where an application permits direct sensor-to-display or local-network communication, eliminating unnecessary gateways, subscriptions and cloud dependencies can reduce cost and complexity. The right architecture depends on security, range, reliability, interoperability and support requirements. Fewer components can also mean fewer points of failure — provided the remaining system is properly engineered.
5. Security and customer control
Outages and cyber incidents are different threats, but both highlight the risks of uncontrolled dependencies. Customer-governed data paths, limited external exposure, appropriate authentication, encryption, segmentation and update processes should be considered from the beginning. Internet independence is not a substitute for cybersecurity; both must be engineered.
6. Resilience begins with power
Radio links and local displays do not operate without energy. A Black Sky-ready solution must define its power budget and include appropriately sized batteries, UPS, generator or other independent supply as needed. Sensor sampling rates, message frequency, radio duty cycle, display usage and realistic battery endurance all matter. A 72-hour resilience objective must be designed, measured and tested — never assumed.
From emergency planning to everyday commercial value
The same principles that support contingency planning can improve normal operations: independent condition monitoring, early warnings, reduced infrastructure dependence, better access to sensor data and flexible integration with existing equipment. For customers, that can mean better visibility, stronger operational continuity and more cost-effective engineering.
A practical resilience checklist
Ask five questions: Which measurements remain essential during an outage? What equipment and communications links depend on mains power, broadband or a third party? Can staff see trusted information locally? How long will each component operate on backup power? Has the complete system been tested under realistic failure conditions? The answers reveal where targeted communications R&D and sensor integration may add value.
BLACK SKY. NO POWER. NO INTERNET. NO COMMUNICATIONS. THINK TIGERTEK.
Tigertek's mission is simple: get important sensor data from anywhere to where it is needed, with practical technology choices, customer control and a focus on value. When conventional connections are unavailable, a carefully designed independent communications path can make a real difference. Let's engineer for the difficult days — and deliver value every day.
