Hardening IEEE 802.11 wireless networks
IEEE 802.11 is a Wireless Local Area Network (WLAN) standard which specifies a radio interface and Layer 2 (Link Layer) protocol for data communications in the 2.4 Ghz spectrum. 802.11b supports up to 11 Mbps of capacity, depending on what part of the world you are in, and has a range of up to a hundred meters or more in open spaces, but more like 50 Meters in a practical office environment using off the shelf equipment. 802.11b is not just...

Radio frequency integrated circuit design
Radio frequency integrated circuit (RFIC) design is an exciting area for research or product development. Technologies are constantly being improved, and as they are, circuits formerly implemented as discrete solutions can now be integrated onto a single chip. In addition to widely used applications such as cordless phones and cell phones, new applications continue to emerge. Examples of new products requiring RFICs are wireless local-area...

The rapid progress of mobile/wireless communication and embedded microsensing MEMS technologies leads us toward the dream “Ubiquitous/ Pervasive Computing.” Wireless local-area networks (WLANs) have been widely deployed in many cities and have become a requisite tool to many people in their daily lives. Wireless personal-area networks (WPANs) provide a cableless personal working area by using wireless interconnection among devices, such...
