NEC Electronics Expands Its Wireless USB Portfolio

NEC Electronics expands its suite of Wireless USB devices with the introduction of the uPD720171 Wireless USB host controller. Building on the company's first host controller (part number uPD720170), the new uPD720171 controller for PCI Express bus interfaces, enables high-speed, wireless data transmission between PCs that have MiniCard or Half-Minicard expansion cards and PC peripheral devices such as wireless hubs, printers, external storage equipment and digital cameras. The new host controller also provides laptop computer connectivity through an ExpressCard slot. Providing greater throughput and higher performance than previous host devices, the uPD720171 controller enables consumers to enjoy wireless lifestyles while maintaining wired USB functionality and ease of use.

Certified by the USB Implementers Forum (USB-IF), the uPD720171 controller conforms to the Wireless USB 1.0 specification and also to the Wireless Host Controller Interface (WHCI) specification developed by Intel with support from Microsoft, NEC Corporation, Philips, Texas Instruments and other experts in Wireless USB technology.

Developed by the Wireless USB Promoter Group, Wireless USB technology builds upon the current USB 2.0 standard, which has been hailed as the next-generation interface standard for computers and multimedia consumer electronics devices. The Wireless USB specifications supports data transfer rates of up to 480 megabits per second (Mbps) of data, comparable to wired USB 2.0 connections at close range. NEC Electronics' new controller can transfer up to 480 Mbps within a maximum range of three meters.

Unwiring the cable connection frees users from having to make cumbersome and unsightly wired connections and enables them to enjoy high-speed data access using Wireless USB. Currently, Wireless USB technology is making it possible for designers to expand the boundaries of computing and digital entertainment to discover new ways for consumers to enjoy digital media.
