The MSD45N combines the 2.4 and 5 GHz signal path to signal U.FL type antenna connectors to
support dual band transmission and receive. An antenna diversity function is NOT supported in
this product. Supported host device antenna types include dipole and monopole antennas.
Regulatory operational requirements are included with this document and may be incorporated
into the operating manual of any device into which the MSD45N is installed. The MSD45N is
designed for installation into mobile devices such as vehicle mount data terminals (which
typically operate at distances greater than 20 cm from the human body) and portable devices
such as handheld data terminals (which typically operate at distances less than 20 cm from the
human body). See “Documentation Requirements” for more information.
