In this paper, we propose Airshark—a system that detects multiple non-WiFi RF devices in real-time and using only commodity WiFi hardware. To motivate the need for systems like Airshark, we start with measurement study that characterizes the usage and prevalence of non-WiFi devices across many locations. We then present the design and implementation of Airshark. Airshark extracts unique feature...

A mobile random network (MANET) is a self-organizing cordless network composed of mobile nodes and requires no set system. Routing is a crucial task in MANET as the nodes are moving. So, the principal goal of your ad hoc routing standard protocol is to determine the correct and reliable way between any couple of nodes with minimal overhead. Routing overhead is an essential metric. In the event ...

This paper deals with the design and implementation of a wireless Local Area Network (LAN), called DECT LAN, providing access to a backbone wired Ethernet network. Digital Enhanced Cordless Telecommunications (DECT) standard provides only the radio interface between mobile devices and Ethernet via a base station. The DECT protocol is implemented as a combination of hardware and software compone...

The self-management of asthma can improve clinical outcomes. Recently, mobile telephones have been widely used as an efficient, instant personal communication tool. This study investigated whether a self-care system will achieve better asthma control through a mobile telephone-based interactive programme. This was a prospective, controlled study in outpatient clinics. From 120 consecutive patie...

We thank Ahlbom et al., the authors of [1] for their interest in our paper [2]. Since this is an important issue, the letter deserves a comprehensive and thorough response. Some authors use brain tumor incidence data from Sweden to dismiss evidence of an increased risk for brain tumors associated with the use of mobile and cordless (wireless) phones as published in peer-reviewed scientific lite...

Recent studies show that high-power cross-technology interference is becoming a major problem in today’s 802.11 networks. Devices like baby monitors and cordless phones can cause a wireless LAN to lose connectivity. The existing approach for dealing with such high-power interferers makes the 802.11 network switch to a different channel; yet the ISM band is becoming increasingly crowded with div...

We performed a case-control study on the use of cellular and cordless telephones and the risk for brain tumors diagnosed during 2000-2003. We report the results for malignant brain tumors with data from 317 cases (88%) and 692 controls (84%). The use of analog cellular phones yielded odds ratio (OR) of 2.6 and a 95% confidence interval (CI) of 1.5-4.3, increasing to OR=3.5 and 95% CI=2.0-6.4 wi...
