Radio Frequency – RF

Radio frequency (RF) is a rate of oscillation in the range of around 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals. RF usually refers to electrical rather than mechanical oscillations; however, mechanical RF systems do exist (see mechanical filter and RF MEMS). Although radio frequency is a rate of oscillation, the term “radio frequency” or its abbreviation “RF”Continue reading “Radio Frequency – RF”

Ad Hoc/BSS/IBSS/Infrastructure/AP/BSA/SSID/DS/Roaming/802.11 ac (IEEE working group)

Wi-Fi Alliance is a trade association that promotes Wi-Fi technology and certifies Wi-Fi products if they conform to certain standards ofinteroperability. Not every IEEE 802.11-compliant device is submitted for certification to the Wi-Fi Alliance, sometimes because of costs associated with the certification process. The lack of the Wi-Fi logo does not necessarily imply a device is incompatible with Wi-Fi devices. The EuropeanContinue reading “Ad Hoc/BSS/IBSS/Infrastructure/AP/BSA/SSID/DS/Roaming/802.11 ac (IEEE working group)”

How to Setup an Ad Hoc Wireless Network with Windows Built-in Utility (Windows XP)

The Ad Hoc mode, also called peer to peer mode, allows nodes to communicate directly (point-to-point) without the need for an AP, as in the following Figure. There is no fixed infrastructure. Nodes need to be in range with each other in order to communicate.  For more information about an Ad Hoc network, please referContinue reading “How to Setup an Ad Hoc Wireless Network with Windows Built-in Utility (Windows XP)”
