CSignum Demos Electromagnetic RadiEM Modem CSignum demonstrated its new RadiEM Modem at Ocean Business. The company touts RadiEM as the ? rst platform to use low-frequency electromagnetic (EM) ? elds to transmit more data wirelessly. According to CSignum, RadiEM is the only technology that can transmit data through the water-air boundary, water column, seabed and subsea structures, as well as connect digital devices in networks below the water with those networks on land and in the air. “EM signals are resilient ©DWTEK sustaining their integrity where sound and light scatter: at the surface; in shallow
