Factors of Bluetooth Technology to Mitigate Interference with Wi-Fi

Bluetooth wireless technology (BT) operates in the unlicensed Industrial, Scientific, Medical (ISM) band in the 2.4GHz frequency range. It randomly uses 79 1Mhz wide channels ranging from 2.402MHz to 2.480MHz. Each channel is occupied for a maximum time slot of 625us. During this time the radio must change the operating frequency, receive or transmit data, and provide enough off time before switching to the next hop frequency. In reality, the time the radio is actually transmitting on a given channel is much less and is dependent on the amount of data being transmitted. WIFI WiFi or 802.11 b/g, also operates in the same ISM band as BT. Due to complicated modulation techniques, 802.11g channels are 20MHz wide while 802.11b channels are 22MHz wide. This means a common WiFi channel can occupy from 20 to 22 BT channels. COURTESY: HTTP://EN.WIKIPEDIA.ORG/ WIKI/IEEE_802.11B-1999 INTERFERENCE For an RF signal to be received by the radios receiver, the RF signal must contain enough energy to be detected by the receiver circuit. The minimum receive level is known as the receivers sensitivity. This is similar to the lowest whisper that a human ear can detect. What if there happens to be two signals present at the same time and both are greater than the receiver’s sensitivity? Which signal will the radio detect? One would think that it would not be able to correctly detect either signal. That would be true if both signals are close to the same power level. If one signal had a higher power level than the other signal by a specific amount, the radio would be able to detect the more powerful signal. This is similar to a human ear being able to clearly understand members at a dinner table while there are many others talking at tables that are further away. The minimum ratio of power level for two signals when a radio can correctly detect the desired signal is known as the carrier/interferer ratio, or C/I. This means that two RF signals can exist on the same frequency at the same time without causing interference if the ratio of their power levels meet the radios C/I specification.

Red Hulk - Marvel Universe Wiki: The definitive online source for ...

Red Hulk As a young man, Thaddeus Ross enlisted in the military and received his nickname from his troops because he "struck like a thunderbolt" when leading them into action. Now he has become the very thing he hated most in life. He is the Red Hulk. Military Man General Thaddeus E. Ross was born into a family with a proud tradition of military service. Both his father and his grandfather served heroically in past American wars. As a boy Thaddeus immersed himself in military history, and he learned how to fly by barnstorming at country fairs. When he came of age Ross enlisted in the military, graduating first in his class at West Point. He married Karen Lee, the daughter of his commanding officer at the time. Ross rapidly rose in rank to captain and then major while serving in his first war. Ross made a great reputation as a leader in combat, but after the war, he was stationed at the nuclear research facility at Los Alamos, New Mexico. There he met nuclear physicist Brian Banner, the father of Robert Bruce Banner. Ross had risen to the rank of colonel by the time he was sent to his next war, during which he became a general in the U.S. Air Force (Ross never rose beyond three-star general). As he gloried in combat, he was dissatisfied with the "desk jobs" he was given before and after the war. Ross's wife, Karen, bore him only one child, his daughter Betty. Karen died when Betty was in her early teens. General Ross came to command Desert Base, New Mexico - a missile base and nuclear research site. He resented the fact that Bruce Banner, a civilian, was appointed supervisor of the gamma bomb project. Moreover, the general had contempt for the scrawny, intellectual Banner for failing to live up to Ross's own vision of true manhood. Making matters worse was the growing attraction between Banner and Betty, whom Ross hoped would marry a military officer. A New War to Fight Banner was transformed into the Hulk as a result of intense radiation exposure during...

Windows 7 Migration Policy - Utah Technical Architecture

Windows 7 Migration Policy DTS Technology Policy 4300-0040 Status: Approved Effective Date: November 1, 2010 Next Review Date: November 2011 Sponsor: ARB Approved By: Architecture Review Board Stephen Fletcher, CIO Introduction The purpose of this policy is to document and clarify the direction of the State for Windows 7 migration. Policy Prior to installation of Windows 7 on agency computers, “the business” must certify that all agency business applications run properly on the Windows 7 operating system. This testing may be done in collaboration with DTS staff as appropriate.  The agency IT Director will be responsible for determining when the business has completed the process of testing and certifying all necessary business applications.  Once this process has been completed, the agency may purchase new machines (as part of the regular replacement cycle) with Windows 7 installed.  Existing PCs are not authorized to have Windows 7 installed (unless originally purchased with Windows 7) but should continue to use the existing operating system licensed for that computer.  On an exception basis, IT Directors may authorize Windows 7 installation on existing machines, if there is an approved business justification. Authority The Department of Technology services is charged in Utah Code 63F-1-104 et seq with the overall responsibility for defining technology standards. The Chief Information Officer (CIO) has rule making and policy making authority for technology standards and practices for the Executive Branch agencies as specified in Utah Code 63F-1-206 et seq, with the exception of those agencies exempted in Utah Code 63F-1-102. Implementation Agency IT Directors must certify that agency applications have been tested successfully with Windows 7, and submit their tested application list to the Architecture Review Board (ARB) for posting on the ARB Wiki. Suggestions for changes, revisions, and additions to this document are encouraged. This standards document will be subject to review and revision six months from the initial date of publication, and every six months thereafter. Suggestions for changes, additions, or revisions may be e-mailed to the Architecture Review Board (ARB@utah.gov) or to Robert Woolley (bwoolley@utah.gov) at any time. Change recommendations will follow approved processes for enterprise standards and policies approval and changes...
