AirMagnet solutions are used by companies from all industries who need to make wireless LANs secure, predictable and compliant. The overall goal of the company is to let customers operate their wireless networks with the same confidence as their wired networks. Most enterprises have this need, which is one of the reasons why AirMagnet has had such consistent success in a variety of industries.
Because of differences in component configuration, placement, and physical environment, every network application is a unique installation. Before installing the system, you should perform a site survey to determine the optimum utilization of networking components and to maximize range, coverage, and network performance. A proper site survey provides detailed information that addresses: RF Coverage Interference Sources Equipment Placement Power considerations Wiring requirements
Consult your written security policy if you are unsure of classification of data information. The following guidelines should be kept in mind when preparing to perform a site survey: Perform the site survey when the RF link is functioning with all other systems and noise sources operational. Execute the site survey entirely from a mobile station. Set your client adapter's RF Transmit level at different settings to determine the minimum level required to cover the wireless cell.
A sine wave, is a mathematical construct (specifically a function) used to model and predict a variety of cyclic phenomena, including the rise and fall of tides, the oscillation of a spring, the incident light hitting the ground from the Sun over the course of a day, the intensity of a sound wave , and millions of other examples. The most basic way of writing a sine wave function is f(x) = sinx, where &quot;sin&quot; means &quot;sine,&quot; and x is the variable being operated on. Amplitude is the maximum positive displacement from the undisturbed position of the medium to the top of a crest. Frequency refers to how many waves are made per time interval. This is usually described as how many waves are made per second, or as cycles per second. Modulation is the process of varying some characteristic of a periodic wave with an external signals In electronics , gain is a measure of the ability of a circuit (often an amplifier ) to increase the power or amplitude of a signal . Signal Loss (Attenuation) is simply a reduction of signal strength during transmission. Refraction describes the bending of a radio wave as it passes thru as it passes thru a medium of different density.
2.4 are 4 inches long and 5 ghz waves are 1 inch long
Signal Loss (Attenuation) is simply a reduction of signal strength during transmission
This is an example of attenuation

Free-pérdida en el trayecto espacio es proporcional al cuadrado de la distancia entre el transmisor y el receptor, y también es proporcional al cuadrado de la frecuencia de la señal de radio
AirMagnet Survey is a software application that lets users perform fast site surveys of their networks and then see a visual “weather-map” of Wi-Fi performance. Users simply import a map of their locations, perform a survey, and then see where they have good coverage and performance, and areas where they could need some improvement. AirMagnet Survey is the industry standard for performing professional site-surveys and is the solution of choice for the vast majority of Cisco SEs when doing a survey in the field. Key Points – AirMagnet Survey Captures ACTUAL Data in the Environment Provides a complete “Weather Map” of Wi-Fi Performance The Clear Industry Leader in Live Site Surveys
AirMagnet Laptop is a software application that provides a complete solution for anyone managing a wireless LAN. AirMagnet Laptop proactively detects hundreds of network problems including security and performance alarms. Users are powered with everything that is needed to quickly pin down any wi-fi issue. This includes detection of rogue devices, configuration problems with the authorized devices, detecting denial of service attacks, security hacks, RF management issues, device overloading issues, excessive bandwidth usage, etc. AirMagnet Laptop Analyzer provides the complete Interference analysis for a Wi-Fi network, that includes interference due to Wi-Fi devices operating in the same channel or an adjacent channel, hidden nodes and non Wi-Fi devices. Users can obtain detailed frame information for any device, channel or frame type. Laptop Analyzer provides a set of active wireless troubleshooting tools, that is not available anywhere else.
