Wireless LAN standardized for SD cards

Jan 12, 2012 at 08:20 GMT

CES 2012: The Secure Digital Association has announced a standard for wireless communications from SD cards. The standard builds on the work done by Toshiba, which has been showing compliant cards at CES. The standard includes two communications systems, denoted 'W' and 'D.' 'W' cards can communicate with other devices (such as tablets and televisions), in a peer-to-peer fashion, or can upload to 'cloud' services.  The 'D' section of the standard aslo allows connection to home networks. 'W+D' cards that allow both communication types will also be available.

SD ASSOCIATION ADDS STANDARDIZED WIRELESS COMMUNICATION TO WORLD-LEADING SD MEMORY CARD STANDARDS

LAS VEGAS – CES Booth South Hall 4 #36231 -- Jan. 9, 2012 – A new SD memory card standard can transform millions of everyday consumer electronics into wireless LAN devices with portable storage and communications. The Wireless LAN SD standard announced today is the SD Association’s first wireless SD memory card standard combining storage and wireless capabilities. Consumers will be able to transfer pictures, videos and other content wirelessly from most existing digital cameras and digital video cameras to web-based cloud services and between SD devices over home networks.

The Wireless LAN SD standard combines the world-leading memory card storage standard with the ubiquitous wireless standard IEEE 802.11a/b/g/n, part of the Association’s strategy to expand SD services and features by incorporating other global standards. This standard is applicable to full size SD/SDHC/SDXC and microSD/SDHC/SDXC memory cards. It taps into a billions-strong SD standards market for which manufacturers can develop products and consumers can reliably use Wireless LAN applications.

“As cloud servers and wireless technologies continue to penetrate the consumer experience, wireless accessibility will become increasingly more important,” said Michael Yang, senior principal analyst, memory and storage, IHS iSuppli. “The addition of wireless capability to the existing SD memory card standard, will enable SD memory cards to remain relevant to shifting market demand, and add value to consumers and manufacturers of new cameras, tablets, and mobile phones.”

With wireless communication capabilities in their familiar SD memory cards, consumers around the world will be able to:

The Wireless LAN SD memory card standard defines two interface types:

The Web interface supports server upload and peer-to-peer functions.
The home network interface supports server upload and home network communication functions.
A Wireless LAN SD memory card can provide both of the wireless communication types, designated by both symbols.

“Wireless LAN SD offers you a standardized approach to transfer pictures, video, documents and other content easily with most existing cameras and video cameras,” said Norm Frentz, chairman of the SD Association. “The Wireless LAN SD memory card standard demonstrates how SD Association innovation continues to respond to market demand and improve consumers’ digital lives.”

For more than a decade, SD standards have increased the value, usefulness and longevity of consumer electronics by allowing consumers to easily upgrade storage instead of replacing devices and creating more electronic waste.
