• 5G Wi-Fi Use Notice
  1. the device for operation in the band 5150-5250 MHz is only for indoor use to reduce the potential for harmful interference to co-channel mobile satellite systems;
  2. the maximum antenna gain permitted for devices in the bands 5250-5350 MHz and 5470-5725 MHz shall comply with the e.i.r.p. limit; and
  3. the maximum antenna gain permitted for devices in the band 5725-5825 MHz shall comply with the e.i.r.p. limits specified for point-to-point and non point-to-point operation as appropriate.
  4. Users should also be advised that high-power radars are allocated as primary users (i.e. priority users) of the bands 5250-5350 MHz and 5650-5850 MHz and that these radars could cause interference and/or damage to LE-LAN devices.
• Antennas information for FCC & IC
  ♦The module itself does not have an antenna. During the test, the host provides a FPC antenna with a maximum gain of 3dBi.
  ♦The module is limited to Yealink installation only
  ♦ Yealink integrators is responsible for ensuring that the end-user has no manual instructions to remove or install module
  ♦For FCC only: The module is limited to installation in mobile or fixed applications, that separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations
  ♦ Antenna installation requirements: refer to Pin Definition, while installing the module, the antenna also has been installed in the host;
