zigbee and BLE in the same board

[Esteban Gutiérrez Correa]

Hello,

I want to make a device that use a Zigbee SoC and a nRF51822 for BLE, and I want to make it in the same board, that imply to have two antennas in the board.

I was wondering if someone could make me some recommendations for this project, it is important for my purpose to avoid the interference.

thanks for your recommendations.

Having two wireless SoC on the same board that run their protocols independently is challenging as one might transmit while the other is receiving. How often will the two SoCs be active at the same time? Do you have a specific Zigbee SoC in mind? If so, do you know if has a co-existence interface, i.e. if the nRF51822 signals the ZigBee SoC via a gpio, then it will hold off its radio operations until the nRF51822 is finished?
