Satellite data system may expand teleradiology's orbit

June 16, 2008

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 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.
