The ClearMesh CM 300 nodes provide citywide broadband coverage to support first responder, video surveillance, transportation, and business community applications. It is an essential component that establishes a citywide wireless network. Designing the node presented Nectar with several challenges, including configuring the optical head for outdoor mounting on roofs, poles, and walls; for accurate aiming to and from connected nodes in the mesh; and for residence to widely varying environmental conditions. In addition to overcoming these challenges, Nectar had to create a design that could be easily assembled and manufactured at low cost.
To ensure that the ClearMesh CM 300 node would perform in extreme environmental conditions, Nectar leveraged industry-leading finite element analysis (FEA) and computational fluid dynamics (CFD) simulation tools to simulate the effects of potential temperature, wind, humidity, and seismic loads. Using these insights, Nectar developed a passive thermal regulation system to withstand extreme heat and cold, a weather-tight sealing system to protect against wind-propelled dust and water, and structural mounting features for secure installations onto rooftops and poles. The firm also labored to utilize low-cost materials and tooling to control assembly and manufacturing costs.
