This stage involves the sampling of traffic. The scan should ideally incorporate the entire band including any ranges that are not specifically defined for local use in a country as well as any proprietary modes.
Passively scanning all channels within the ISM 2.4 and 5 GHz bands. The common stages in this process consist of: 1 This process can aid in the location of rogue devices and in investigating possible breaches. To conduct a wireless site survey you will need a number of wireless network monitoring tools. The next chapter discusses more on radio frequencies and spectrum analysis.Ī wireless site survey report includes the availability of any licensed frequencies, any existing frequency usage by other agencies or companies, and, if necessary, developing a shared channel plan policy. A spectrum analysis provides additional information during the architectural design stage to ensure that once operational, the recorded video archives achieve the system requirements. However, with synchronous real-time video surveillance where each frame could potentially capture the identity of a person of interest, slow connectivity or reduced bandwidth means lost real-time data.
It’s not asynchronous, so if there’s a complaint about a slow network connection of slow download speeds from reduced bandwidth due to interference, nothing is lost. Remember that designing for video surveillance and physical security is unique. Monitoring while surveying with electronic equipment uncovers overlapping frequencies. Interference from other wireless equipment is probably the biggest reason for wireless network failures and problems, either during initial deployment or once the network has been established.
