700MB Movie Download in One Minute via Wireless USB

Up until now, wireless USB has not really managed to hit it mainstream, probably due to the fact that it’s still a rather young technology, which implies some pretty high costs (the price of wireless USB adapters is still quite high). However, things might change dramatically in the future, as Samsung has announced the development of a new System-On-Chip (SoC) designed specifically for the upcoming ultra-wideband (UWB) market.

The fresh Samsung W-USB SoC is a single chip solution featuring a built-in ARM core, a UWB physical layer, and a memory controller. It uses advanced CMOS process technology and 3.1-10.6 GHz-band UWB technology, and also provides an SD card, an MMC, a NAND flash memory, and a high-speed USB 2.0 OTG (On-The-Go) interface without additional logic circuitry.

One of the most important things worth mentioning about this highly innovative chip from Samsung is its level of versatility. Apparently, this chip will work on a very wide array of consumer electronic products, including here digital cameras and mobile phones, wireless printers, beam projectors, wireless hard disks, wireless displays, and wireless speakers. In other words, you’ll be able to stream photos from your mobile phone directly to a TV set, or listen to the music stored onto an MP3 player directly via your wireless speakers.

Besides versatility, the chip should also provide a fairly high speed, of around 120Mbps. According to Samsung, this translates into the possibility of downloading a 700MB movie in under one minute.

Other two important issues related to the W-USB SoC are that of security and power consumption. As far as security is concerned, Samsung’s chip features a 128-bit AES (Advanced Encryption Standard) encryption algorithm and a static signal that makes hacking through wiretapping and signal tracing difficult. The power consumption level has also been maintained at a minimum, since we’re talking about somewhere around 300mW (milliwatt).
