I have seen the nRF24L01+ ( http://iteadstudio.com/store/index.php?main_page=product_info&cPath=7&products_id=53&zenid=qa08tp07o8bn54mjpo155e5o1 ) module linked before as a solution for low cost short range communication between MCUs, but finding a reliable range numbers has been difficult.

Does anyone who has experience using these chips in a real environment give an approximate range at the lowest data rate?

That module hasn't got a chip antenna!

Range depends a lot on the relative orientation of the two modules. I can get about 20m indoors, but I haven't experimented with different data rates and power levels.

Sorry, I meant PCB antenna (I noticed it while going to bed last night). – pfyon Jun 4 '12 at 12:22
Thanks, I ended up ordering a module with the PA and LNA circuit (for my base station) as well as the simple pcb antenna one for my "satellite" device. – pfyon Jun 7 '12 at 2:05
