On the Intel Curie documentation, page 46 on the below document:

http://www.intel.com/content/dam/support/us/en/documents/boardsandkits/curie/intel-curie-module-data... http://www.intel.com/content/dam/support/us/en/documents/boardsandkits/curie/intel-curie-module-data...

The TX (transmission power) is listed as varying from -20 to +4 dBm in 4 dB increments. These units are incompatible.

Please provide confirmation of the TX units, millidecibels rather than decibels. Thank you.

Hello WSmitherman_EOG,

 

 

Thank you for your interest in Intel® Curie™ Boards.

 

 

The information from the document is correct, dBm or decibel-milliwatt (not millidecibels), is an electrical power unit (in decibels), referenced to 1 mW; dB on the other hand, is a relative unit that indicates ratio or gain (it is a dimensionless unit), that is why the units in the document are compatible.

 

 

Have a nice day.

 

 

Regards,

 

Andres V.
