Satellite data system may expand teleradiology's orbit

The launch of the experimental Japanese WINDS satellite in late February holds promise for teleradiology, with researchers hoping the geostationary Ka-band communications satellite will boost teleradiology into a new ultrahigh-speed communications era.

The satellite could offer Internet speeds of up to 1.2 Gbps. Such a backbone would address bandwidth limitation issues that plague teleradiology operations, particularly in remote locations. Ultrahigh-speed communications would also facilitate remote education.

The satellite carries high-gain antennas and a high-speed asynchronous transfer mode switch, according to the Japan Aerospace Exploration Agency. Data transfers of 1.2 Gbps will be available to clinics and offices with 5-m antennas.
