Toshiba to promote TransferJet at CES

You may or may not be familiar with TransferJet, a technology that allows for short range wireless data transfer speeds of up to 560Mbps using the 4.5GHz band. So far there isn't much in terms of devices that supports the standard, but Toshiba and the TransferJet consortium are set to change this at CES where they will be showing off a range of new devices that supports the technology.

You may or may not be familiar with TransferJet, a technology that allows for short range wireless data transfer speeds of up to 560Mbps using the 4.5GHz band. So far there isn't much in terms of devices that supports the standard, but Toshiba and the TransferJet consortium are set to change this at CES where they will be showing off a range of new devices that supports the technology.

Toshiba's press release didn't reveal too much about the specific devices, but we can apparently expect tablets, laptops and smartphones featuring TransferJet. As you'd expect, Toshiba is one of the driving forces behind TransferJet alongside Sony, but many other companies are standing behind the technology including Canon, JVC, Nikon, Olympus, Panasonic, Pioneer, Samsung and Sony Ericsson to mention a few of the promoters of the standard. So far most of the companies are Japanese and this is part of the reason why the technology hasn't taken off.

Another reason is the relatively high cost and this is what Toshiba is hoping to address with its new LSI, the TC35420 which is a single chip solution for TransferJet that incorporates bot the IC and the RF part. This should not only help simplify the implementation, but also help drive down cost, although at US$5 a pop in sample quantities one can hardly accuse Toshiba for selling the chips on the cheap. Compare this to a USB 3.0 host controller which by now we'd expect to be below US$2 in large quantities and you can see why TransferJet is struggling a bit.

Actual transfer speeds of TransferJet are close to that of USB 2.0 at 375Mbps (USB 2.0 has a theoretical data speed of 480Mbps), so as long as you don't mind plugging in a cable, there are much faster alternatives. In as much as we're all for ease of use, it's hard to justify the extra cost and getting slower speed than a wired connection can offer at lower cost. Still, it'll be interesting to see what Toshiba and the TransferJet consortium will demo at the show.
