Welcome to the WISP Wiki.

This wiki contains information pertaining to the older WISP 4.1 platform. See the new WISP 5 wiki at wisp5.wikispaces.com

The NFC-WISP project has now been open sourced!! See the new nfc-wisp wiki to learn more!

Thanks to JaeMin Shin and everyone in the Computer Network Lab at South Korea's Sungkyunkwan University for their contribution of a version of the WISP code that can operate with the Asian version of Impinj Speedway R420 readers, the R420-GX2!! Find the new WISP5 firmware repository branch here.

This project is supported in part by NSF Grant CNS-1305072, entitled "CI-ADDO-EN: Infrastructure for the RF-Powered Computing Community." Additional support from NSF Grant EEC-1028725, Intel Corporation, and the Google Faculty Research Awards program.

Book with many wisp-related articles available now! "Wirelessly powered sensor networks and computational RFID."Publisher's webpage., Amazon.com product page.

WISP (Wireless Identification and Sensing Platform) is a sensing and computing device that is powered and read by off the shelf UHF RFID readers. WISPs have on board microcontrollers that can sample a variety of sensing devices, creating a wirelessly-networked, battery-less sensor device. WISPs have powered everything from analog light sensors to temperature sensors to strain gauges. The computing features of WISPs have also been used by RFID security researchers.

If you're interested in using WISPs, take a look at the WISP Challenge Website.

Wiki Sections

(grouped on the navigation bar to the left)

Downloads and Releases includes status information and instructions for obtaining current releases.

Getting Started has tutorials for getting everything set up and running.

Community has various informational sections for WISP collaborators.

Current Documentation and Archival Documentation are for in-depth explanatory information, as opposed to Downloads and Releases which is for quick status updates.

Learning includes informational pages that are not WISP documentation or getting started tutorials. Topics include power management, RFID protocol, etc.

Management has administrative tasks and to-do lists for Wiki developers and WISP developers.

The Wiki is currently needs development help. See the Wiki ToDo list for ideas.
