R250 Pro Ruggedized Radio Over Cellular Transceiver

An innovative ruggedized cell phone with Land Mobile Radio capabilities developed for Ericsson Indelec, Inc., Spain. Stone Mountain Design interfaced with the PCB layout/design group in Spain and a variety of mechanical groups and tooling houses across Europe and the Far East. We generated the detailed design in 3D solid model format and provided full finite element analysis, in-house prototyping, 2D documentation and tooling support. Several patents pending. Ultra-complex two shot rubber overmolded plastic substrate housing, with integrally molded side buttons resulted in a rugged and highly durable two-way radio. Notably, the radio also exceeded the customer’s fully submersible product specifications. To supplement our customer’s satisfaction, Stone Mountain Design completed the entire development cycle in 12 months.
