Samsung Electronics today introduced its latest wireless universal serial bus (USB) solution, developed using Ultra Wide Band (UWB) technology.
Offered in a two-chip set, Samsung’s newest S3C2680/ S5M8311 WUSB solution enables high-definition content to be wirelessly transmitted from a mobile host device to a tethered device for viewing.
Initial applications are high-resolution cameras, camcorders, TVs and PCs with prospects for adoption in other applications including tablet PCs, printers, beam projectors, portable HDDs, Blu-ray players, and mobile handsets.
“The ability to handle wireless high-speed data transmission while consuming less power is a key requirement for many consumer electronic devices,” said Samsung's Yiwan Wong. “Due to power-to-performance issues, previous generations of WUSB products were unable to meet expectations."
The Korean company's new WUSB chipset delivers up to 480Mbps data transmission rate, at an average power consumption of less than 300mW.
Manufactured using its advanced 65nm low-power logic process technology, the new chipset is a combination of a system-on-chip (SoC) baseband processor and an RF transceiver.
The new hardware is small enough to be crammed into an SD card, USB dongle, or embedded in any number of mobile devices.
It allows wireless transmission at an actual information throughput rate of over 200Mbps with power efficiency ten times greater than that of the 802.11g WiFi standard. With multi-threshold support, this new chipset also has decreased power consumption by 30 percent over existing WUBS chipsets.
With an embedded NAND flash memory controller built in, Samsung’s new WUSB chipset is the only product in the market that can support WUSB-enabled SD cards according to Samsung. This type of WSUB-enabled SD card allows pictures and video captured with a digital camera or camcorder to be transmitted wirelessly from the device to a host computer, a TV or a PC monitor for viewing without any wire connections to download the contents from the SD card.
Using an ARM 9 core, Samsung’s WUSB chipset features WiMedia v1.2 PHY and also has various interfaces such as SDIO, SD card, SD host, as well as a NAND flash controller and two high-speed USB 2.0 PHYs. This chipset solution also has a 128-bit AES encryption algorithm for secure data transmission.
Samsung’s S3C2680/S5M8311 WUSB chipset is now sampling to OEMs and will hit mass production by final quarter 2010.
