Nova Engineering recently announced the addition of unidirectional link detection and avoidance (ULDA) to its NovaRoam mobile routers. The ULDA feature allows NovaRoam routers deployed in a mesh network architecture to automatically discover unidirectional link conditions prior to establishing a new route. Once bad routes are detected and designated, the routers avoid them as they continue to search for a bi-directional link, the company said. The result is increased network uptime, higher throughput, longer communication range and more stable operation, according to the company.
