dule with on-board low power application processor. It is targeted at applications that send infrequent data packets over the network. Typically, these 802.11 applications will place a higher priority on system cost, power consumption, ease of use, and fast wake-
up times as compared to high throughput. The RTX4100 has received regulatory approvals for modular devices in the United States
(FCC) and Canada (IC), and regulatory approvals in Europe (ETSI). The modular approval allows the integrator to place the RTX4100 using either the internal antenna or an approved antenna inside a finished product without having to perform costly regulatory testing. The requirements the integrator must fulfil to use modules without additional testing are listed in this Application Note. 1.2 Document History 2012-08-28 PEW V1.0 Official release Disclaimer: This document can be subject to change without prior notice. 1.3 Document References There are no sources in the current document.

The RTX4100 does comply to the FCC Part 15 section 15.207(c) for battery powered omitting FCC Part 15 section 15.207(a). FCC Part 15 Section 15.207(a) states: Except as shown in paragraphs (b) and (c) of this section, for an intentional radiator that is designed to be connected to the public utility
(AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies, within the band 150 kHz to 30 MHz, shall not exceed the limits in the following table, as measured using a 50 H/50 ohms line impedance stabilization network (LISN). Compliance with the provisions of this paragraph shall be based on the measurement of the radio frequency voltage between each power line and ground at the power terminal. The lower limit applies at the boundary between the frequency ranges. Table and other paragraphs refered to in quote can be found in FCC Part 15. 2.1.1 FCC Labeling Requirements The RTX4100 module has been labeled with its own FCC ID number and if the FCC ID is not visible when the module is installed inside another device, then the outside of the finished product into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following:
Contains Transmitter Module FCC ID: S9J4100
-or-
Contains FCC ID: S9J4100 This device complies with the Part 15 of the FCC Rules.
(1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 2.1.2 End User Manual The end user manual should include the following statement:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
