The module realizes the necessary PHY/MAC
layers to support WLAN applications in
conjunction with a host processor over a SDIO
interface.
The module also provides a Bluetooth platform
through the HCI transport layer. Both WLAN
and Bluetooth share the same antenna port.
Need to get to market quickly? Not an expert in
802.11. or Bluetooth? Need a custom
antenna? Would you like to own the design?
Would you like a custom design? Not quite
what you need? Do you need help with your
host board? LS Research Design Services will
be happy to develop custom hardware or
software, integrate the design, or license the
design so you can manufacture yourself.
