5 GHz Band WLAN Device DFS Tests

MainVisualDFS3.jpg

The recent popularity of smartphones, tablets, etc., has caused an exponential increase in WLAN traffic, resulting in demand for faster communications speeds to help reduce traffic congestion. Consequently, not only is use of frequency bands conventionally reserved for indoor traffic being investigated for outdoor traffic in the 5 GHz WLAN space, but also new 5 GHz band WLAN devices are being actively developed, promoting adoption of newer standards facilitating faster communications speeds. Since 5 GHz band WLAN devices can detect meteorological and marine radar, etc., systems using the 5.3 GHz/5.6 GHz bands, they require a built-in Dynamic Frequency Selection (DFS) function for suppressing signal collisions. Installing the MX370073A and MX370075A in the Vector Signal Generator MG3710A supports FCC, ETSI and TELEC-compliant test signals required by the DFS function test for WLAN devices to facilitate efficient development of 5 GHz band WLAN devices.

Features

  • Full support for all required test patterns
    About 400 test patterns must be supported just for ETSI.
    The MX370073A/MX370075A have all the waveform patterns required by the test, helping reduce the preparation burden.
  • Easy operation by just selecting and loading waveform patterns
    Even inexperienced operators with little knowledge of the DFS test and equipment can run accurate tests efficiently.
  • Supports FCC, ETSI, TELEC Standards
    All key DFS test standards are covered.
