Wireless USB Catches Up With USB 2.0 in Transfer Speed
NEC Electronics Corp demonstrated a wireless data communication in a high bandwidth ranging from 6.3 to 7.6GHz by using its Wireless USB-compatible LSI chip at Intel Developer Forum (IDF) Fall 2008.
NEC Electronics also exhibited a prototype system whose effective transfer speed was enhanced to more than 200Mbps by improving its firmware. In the past year, the company showcased a system featuring a effective transfer speed of about 130Mbps at IDF 2007.
This time, NEC Electronics used a PCI Express card adapter equipped with the company's host controller LSI chip, μPD720171, a hub incorporating its DWA (device wire adapter) LSI chip, μPD720180, and so forth. The company wirelessly connected the hub with a notebook PC in which the adapter was inserted and transferred video and image data.
