Samsungs Wireless USB Chips Coming to Phones, Cameras, Laptops

Samsung has created a new wireless universal serial bus (W-USB) System-On-Chip (SoC) which promises to allow mobile devices such as phones camera and laptops to connect to each other or other devices through an interface that is virtually identical to a cabled USB connection, only without the wires.

The perks of keeping the USB technology in the W-USB SoC are numerous. One important factor is security; with the proper encryption, USB can be a relatively secure technology. Furthermore, USB is fast, as is W-USB. With Samsungs system, a 700 MB file takes approximately a minute to copy.

The new tech works in the 3.1~10.6 GHz-band and uses CMOS technology. Samsungs single chip solution consists of an ARM core, a UWB physical layer, and a memory controller with SD card, MMC, NAND flash memory, and a high-speed USB 2.0 OTG (On-The-Go) interface also built in. The UWB transmitter offers a throughput of 480Mbps, with a speed under average payloads of around 120 Mbps, compared to 50 Mbps using the most advanced Bluetooth technology (currently not yet standard).

The signal is also hard to hack as it employs a 128 bit AES (Advanced Encryption Standard) encryption algorithm. It also uses a static signal to further prevent signal monitoring.

All of these features are packed into a small power envelope of 300mW. Samsung will begin shipping the chips in Q2 2009 and expects them to be invading electronic devices of all types by holiday season of this year.
