“…DSSS radios are believed to operate better for large data packets in low to medium interference environments, while FHSS radios operate better for small data packets in high interference environments. Moreover, FHSS radios perform better indoors and in harsh multipath environments because frequency hopping techniques are able to manage multipath fading environments by hopping to new frequency channels [ 94 ].…”

Current progress in wearable and implanted health monitoring technologies has strong potential to alter the future of healthcare services by enabling ubiquitous monitoring of patients. A typical health monitoring system consists of a network of wearable or implanted sensors that constantly monitor physiological parameters. Collected data are relayed using existing wireless communication protocols to a base station for additional processing. This article provides researchers with information to compare the existing low-power communication technologies that can potentially support the rapid development and deployment of WBAN systems, and mainly focuses on remote monitoring of elderly or chronically ill patients in residential environments.

The proliferation of commercial-off-theshelf (COTS) and low-cost wireless communication technology has expanded into many new applications, many of which are relevant to the international security community. Although most applications of these new wireless technologies are for architectures typical of a business enterprise, the need to wirelessly monitor the transportation of nuclear materials inside a fully enclosed metal transportainer or vehicle is an important use. However, the complexity and changing performance of the different spread-spectrum protocols make a selection between these different wireless technologies difficult. The nature of the problem becomes complex within a highly RI-reflective metal trailer approximating a Faraday cage or metal box. The addition or removal of highly RF-reflective metal containers within this environment further complicates the wireless communication and causes the multipath environment to change. Tests were conducted for different wireless spread-spectrum communication technologies using worst-case scenarios for different configurations (numbers) of metal containers. This paper provides an evaluation of the results of these tests and compares the performance for IEEE 802.11, OpenAir, and HomeRF spread-spectrum protocols of a wireless communication environment typical of metal transportation vehicle which could used to transport nuclear materials.
