You've probably heard of Bluetooth
. You may have even heard of Wi-Fi
Direct. But have you heard of TransferJet? That's Sony
's own short-range
transfer protocol, and the company has been quietly pushing it into
more and more products over in Japan for the past year or so. A few
TransferJet cameras have emerged, as well as a few TransferJet USB
The idea is simple. A TransferJet-enabled device can send short-range,
high-speed communications to a TransferJet-enabled PC or a TransferJet
adapter. But before Sony really puts a huge marketing effort behind the
technology, they're introducing the CXD3270GG second generation
transceiver chip. It's fully compatible with PCI Express and USB 2.0,
while the first generation edition supported just PCI and SDIO. The
newest module also requires fewer extra parts (namely a bridge chip and a
general purpose microcontroller) to function.
The second gen hardware also demonstrates data transmission as high as
300Mbps, but higher speeds have been recorded under ideal circumstances.
Sony has also managed to trim power consumption on the new chip, not to
mention the cost of building it. Currently, plans are to mass produce
the second generation chip at the end of this year, with each sample
priced at around $22 for companies who wish to buy in bulk and
integrate. We suspect Sony will use CES 2011 as a launching pad for next
year's TransferJet lineup, but by that time Bluetooth 4.0 may already
be well into the commercial stages. Looks like a short-rage war to us!
