18. WiBro 단말 Technical Issue
CF, PCI, SDIO interface
We can also choice a CF or PCI Interface.
But in this case, we have to make a Glue Logic

MSM chipset internally has a SDIO Interface.(MSM6500 -> 1bit, MSM6550 -> 4 bit)
therefore it will be one of the most simple connection between MSM and Wibro BB chipset.
