Can anyone suggest me Layout guideline or Xbee Pro S1 ?

Hello All,
Can any one suggest me recommended layout guide lines for XBee Pro S1.

How much ground required for it or any special take care in layout for better performance of it ?

Have you read over the product manual or looked at the XBIB schematics yet?

Dear Sir,
I have read product manual and schematic, but I didn’t find it.
Please provide me link or document name which contains recommended layout guidelines for it.

Digi does not offer a separate Guide for how to Layout a board to use the XBee modules.

In general, standard engineering practices for use with any IC are what is expected. Any special circumstances such as keep away areas are listed in the manuals in the Manufacturing sections.
