Why is the Cisco MPI350 not available for aftermarket
A. The Cisco MPI350 cannot be sold as an aftermarket adapter
Regulatory certification is based on the MPI350 being coupled with a
particular antenna. Although modular regulatory approvals are available, they
only apply to the original equipment manufacturer (OEM), who is responsible for
embedding similar antennas in different devices. Modular regulatory approval
does not eliminate the restriction on aftermarket sales since the end user
might embed the adapter in devices with unapproved antennas.
Although the MPI350 is based on the standard Mini-PCI Type IIIA form
factor, there are nevertheless variations in how an OEM embeds the adapter,
including how the adapter is secured in the device, how diversity is
implemented (on-radio vs. off-radio), and whether external LEDs or a radio off
switch is supported.
Potential warranty issues preventing an enduser from embedding the
MPI350 in a laptop or other device.
