    5GHz Wireless Frequency: Properties, Applications & Comparison to 2.4GHz WiFi

    What is the 5GHz frequency? This is a frequency at which electromagnetic energy can be transferred from one point to another in waves. One gigahertz is equal to one billion Hertz, which measures cycles per second. The 5 gigahertz frequency band is denoted as super-high frequency (SHF) by the International Telecommunications Union (ITU). It may also be described as a [...]

    If Antenna frequency band exceeds needed range: Use Filter on system board to reduce excess band

    Example: You need only 860-960 MHz GSM band but the antenna covers 800-960MHz: One customer told us that using an antenna that includes 824-960 band allows too much interference, that comes from the low end of that band 824-860MHz. Our recommended solution is to add a filter in your system board (or AP [...]
