- RF Spectrum Policy: Future-Proof Wireless Investment Through Better Compliance
- Radio Frequency RF spectrum is an overlooked but critical resource. It is through the spectrum between 800 MHz and 5.9 GHz that an organization will connect laptops and PDAs to the network, talk on cellular phones, cordless phones, and headsets. Unless properly managed, many of these technologies will crowd the...

- An Application Framework for Efficient, Reliable and Secure Access to Memory Spot
- Memory Spot is a microchip developed by HP Labs at Bristol. Compared to Radio Frequency IDentification RFID devices, Smart Cards and other Near-Field Communication NFC devices, this chip provides much larger storage capacity, faster data transfer rate, and smaller physical dimensions. The chip is normally passive and is energized by...

- The Case for Virtualized Wireless Access Networks
- Densely populated areas such as city centers are often sprinkled with numerous wireless access points operated for commercial or private use. Together they create what's known as tragedy of the commons phenomenon: without proper coordination, a significant amount of license-exempt radio frequency resources is wasted due to contention at shared...

- Making RFIDs Unique - Radio Frequency Certificates of Authenticity
- A Certificate Of Authenticity COA is an inexpensive, digitally signed physical object that has a random unique structure with high cost of near-exact reproduction. An additional requirement is that the uniqueness of COA's random structure can be verified using an inexpensive device. This paper proposes a design for objects that...
