Japanese consumer electronics giant, Sony Corp., has recently introduced its own shortrange, wireless data transfer technology that could be a direct competitor to the more widely supported wireless USB standard.
TransferJet, as the Sony technology is called, offers a theoretical data transfer rate of up to 560Mbps in the 4.48GHz band, with average realworld transfer rates estimated at around 375Mbps. It only operates over very short distances of 3cm or less, due to its lowpowered nature.
Wireless USB, meanwhile, delivers speeds of around 480Mbps, over a distance of up to 3 meters, but its use of multiple spectrum bands is a key disadvantage, causing it to suffer from greater radio interference in certain situations.
Sony intends to market TransferJet, which it unveiled at the recent Consumer Electronics Show in Las Vegas, as ideal for transferring data from mobile phones, digital cameras, and camcorders onto television sets. Users could view footage by simply placing the host device next to a receiver on their TV.
TransferJet would also be useful to quickly transfer songs between cell phones and portable music players.
Sony has yet to release details of when TransferJet might start appearing in its products.
