Water, electricity, gas and telecommunications providers have field operations involving buried cables and pipelines, where the characteristics defined by the Sonim Rugged Performance Standards ensure 3-year service life and usability under duress in arduous working conditions that create unacceptable return rates and cost of ownership with lesser devices (see Construction above). For customer premises installation and maintenance, enterprise class GPS performance with unpreceented GPS tracking battery life allows the nearest worker to be accurately located and dispatched to the customer site. The safety of workers at risk climbing towers, digging trenches or descending into man-holes can be monitored with Sonim’s man-down/lone worker solutions. For water utilities, Sonim’s IP-68 products are certified for submersion in 2 meters of water and in practice stand up to water jets at extreme pressure that may escape from leaking pumps and pipes.
