Note: The OEM is free to choose another vendor’s antenna of like type and equal or lesser gain as an antenna

appearing in the table and still maintain compliance. Reference FCC Part 15.204(c)(4) for further

information on this topic.

To reduce potential radio interference to other users, the antenna type and gain should be chosen so

that the equivalent isotropically radiated power (EIRP) is not more than that permitted for successful

communication.

6.1.4 Power Exposure Information

In general, there are two agency classifications for RF radiation exposure in wireless applications:



Mobile – A mobile device is defined as a transmitting device designed to be used in such a way that a

separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating

structures and the body of the user or nearby persons. The RM024 is fully modular approved for mobile and

fixed applications. Reference FCC Part 2.1091 for further details on mobile devices.



Portable – Portable is a classification of equipment where the user, in general, is within 20 cm of the

transmitting antenna. Portable equipment is further broken down into two classes; within 2.5 cm of human

contact and beyond 2.5 cm. The RM024 does not hold a portable approval classification due to its peak

output power and modular approval restrictions. Further RF evaluation is required by customers who want

to use the RM024 in portable applications. Contact a qualified test house or a Laird Technologies

representative for further information on this topic. Reference FCC Part 2.1093 for further details on

portable devices.

A Maximum Permissible Exposure report has been created which shows the minimum distances for Public and

Occupational use of the RM024.

Note: Occupational Limit Minimum Distance = 4 cm

Public Limit Minimum Distance = 9 cm

A full MPE report is available upon request.
