Its use implying ability to transceive wireless signals to and from a mobile handset at a quality unparalled by any other wireless competitor.
Although preliminary testing has not confirmed these speculations, it has been suggested that "Mad Seeg does not adhere to the laws of physics!". It is believed that speculations were brought on by other phenomenon such as PC4 and EDGE.
