Our initial fixed sensor network was deployed in the immediate aftermath of 3/11 with the intention of providing ongoing measurements from specific locations primarily in Fukushima. Each Pointcast device required existing infrastructure and a labor intensive custom installation. Ongoing maintenance, updates and trouble shooting had to be done in person, with only a few volunteers being able to fill that role. This resulted in poor functional reliability as devices would be offline for weeks or months at a time awaiting service or relocation. These devices are now depreciated and being replaced by our newer solar models.
