    Recently I have designed board on which Ethernet and gsm module need to be placed. Already I have exported Ethernet related chip to pcb and arranged in this order s shown in below image[​IMG]

    This is how I placed U10 (Ethernet-spi controller), U9(magnetics) ,J2 (RJ45).Whether this plcmnt is correct?? This complete board is consists 4layers. Mid-Layer 1 will be power plane. Mid- Layer 2 will be ground plane.

    One more GSM module need to be placed yet, where I don't have enough place on top layer except on below layer ...

    My question is.... 1.Shall I place gsm below this Ethernet setup..?

    2.what are the pros & cons if I place in this Passion.

    1. Is there any other option to place?
