Don't know how many of you remember Sony's Transfer Jet technology that promised to deliver fast wireless transfer speeds for devices that are in close proximity to one another, but the Japanese company has just come forward with a second generation of TransferJet chips that promise to offer even faster transfer speeds while also boasting an improved power consumption.

If that doesn't ring any bells to you, then you may check out one of our previous reports regarding this technology, but, basically, TransferJet enables devices to exchange data at speeds up to 375 Mbit/s when the two gadgets are in close proximity to one another, about 3cm (1.25 inches) or so.

So, recently, Sony has just developed a second generation of its TransferJet chip, needed in order to enable this technology inside your devices, that is now able to support the PCI Express and USB 2.0 interfaces.

This eliminates the need for a bridge chip and micro-controller, enabling Sony to lower the power consumption from approximately 1W to somewhere between 500 to 600mW in this second generation, CXD3270GG, chip.

Speed was also increased in the CXD3270GG, Sony going from a maximum of 190Mbps in the first-generation products to more then 300Mbps, the Japanese company transferring an 180 MB video file at a speed of about 350Mbps during a live demonstration that took place at CEATEC.

Impressive as this may sound, even more important is the fact that by enabling a lower power consumption in its chip, Sony will make this technology far more friendlier for devices such as netbook PCs, tablets, smartphones and other gadgets that have more stringent power consumption requirements.

Finally, Sony is saying this chip is now sampling to its partners for about $21.18 US, planning to mass produce it by the end of 2010, so this will soon go head to head with Bluetooth 4.0. (via Tech-On)
