RF Module placement amidst two other RF modules

[sridharan_eee]

Dear Members,

I am currently developing RF module based circuit prototype. This design
includes 3 different RF modules. Even though the module placement
recommendation given in datasheet, I am concerned of placing Zigbit module amidst
other 2 modules in PCB.

Please refer to the attached image, which shows the pcb layout of RF
modules placement.

I need your suggestions, tips and help in this regard;

1. Placement

Option-1. Placing Zigbit MNZB-24-A2 in the corner of PCB; other two
modules will sit adjacent with 1 inch distance.

Option-2. Placing Zigbit MNZB-24-A2in the middle of other two modules
at a distance of 1 inch from them.

Which option I should use for the design?

2. Tolerance of MNZB-24-A2
What is the tolerance of Zigbit MN-24-A2for any other frequency. Is it
tolerant to Wifi/blue tooth etc.
