Building resilient smart cities requires cost-effective, infrastructure-independent communication. goTenna’s low SWaP-C long-range communications solution ensures network resiliency and failover capabilities, supporting critical data pathways even in disrupted environments. By operating without traditional infrastructure, cities can rapidly deploy ad hoc smart networks, validating smart city concepts at low cost while ensuring continuous connectivity. This scalable system enables gradual, phased upgrades, expanding across localities, infrastructure, and technology layers—such as deploying transit connectivity before integrating personal mobility solutions. Its seamless extensibility supports independent failover networks and energy-resilient operations, ensuring urban leaders can maintain essential communication during crises. As a scaffolding for smart city growth, this solution provides a secure, adaptable framework that supports sustainable urban development, from initial deployment to full-scale innovation. By integrating goTenna’s technology, cities can establish reliable, scalable networks that evolve alongside their infrastructure needs.
