BVS Wireless Security White Papers

PDF	Title	Abstract	Date
	NEW Selection of Systems for Cell Phone Detection & Location in Confined Spaces NEW	Before committing to a detection system, the prospective user needs to assess the extent to which each of these factors is applicable in a building or facility where the system would be deployed.	6-20-11
	European Carriers Agitated with U.S. DECT 6.0	Use of DECT 6.0 phones in Europe by U.S. and Canadian expatriates have been noticed to cause significant interference in the uplink bands of the European UMTS licensed services. This paper discusses the problem and proposes a detection-based strategy for preventing such use of DECT 6.0 phones..	2-9-11
	Detect & Locate Contraband Cell Phones	The advent of the cell-phone technology with the relentless push towards micro-miniaturization of devices increases the temptation to exploit and mis-use this technology for illegal purposes. Consequently, a very real need exists today, for individuals, businesses, institutions and the government to take measures to detect and identify the unauthorized use of cell-phones within the bounds of their controlled premises and facilities.	3-16-10

BVS Wi-Fi White Papers

PDF	Title	Abstract	Date
	Multipath Detection	It is common to have signal power from the same transmitter arrive at the receiver through different paths. Since each of these paths typically have different lengths, the signals arrive at the receiver delayed from one another and often with a different RF carrier phase. These signals can combine destructively and reduce the signal power or, if the delays are significant enough, they can cause inter-symbol interference. The combination of signals at the receiver that arrive from different paths is called multipath.	7-3-09
	Wi-Fi Antenna Alignment & Rogue AP Detection	There are many factors associated with the deployment and maintenance for 802.11b/a/n/g Networks of WiFi networks today. Providing an efficient and secure wireless network takes a considerable amount of time and effort.	1-29-09
