The equipment is described as follows: Model FCC ID IRIS-W101-00B XPYIRISW1 IRIS-W101-10B XPYIRISW1 IRIS-W101-30B XPYIRISW1 IRIS-W106-00B XPYIRISW1 IRIS-W106-10B XPYIRISW1 IRIS-W106-30B XPYIRISW1 IRIS-W161-00B XPYIRISW1 IRIS-W166-00B XPYIRISW1 In CFR Title 47 Chapter I Subchapter A Part 15 Subpart C Section 15.212 there are eight numbered requirements that our device complies with: 1. The modular transmitter must have its own RF shielding Yes. The module has its RF-parts enclosed by a shield cover soldered onto the module ground plane. 2. The modular transmitter must have buffered modulation/data inputs Yes. The module do not have modulation inputs. The electrical interface available to the module integrator consists of Power supply, UART, RMII, SPI and I/O signals. The interface signals are internally buffered by the module System on Chip and cannot affect the modulation. Detailed instructions on how to connect these interface signals are given in the integration manual. 3. The modular transmitter must have its own power supply regulation Yes. The module SoC (System on Chip) has its own internal voltage regulators. In case the supply voltage fluctuates internal voltages will be kept unaffected. 4. The modular transmitter must comply with the antenna requirements of Section 15.203, 15.204(b) and 15.204(c) Yes. The RF-port of module versions of IRIS-W101-00B, IRIS-W101-10B, IRIS-W101-30B and IRIS-W161-00B is available at a solder land and the antenna trace reference design guides the module integrator how to connect this solder land to a U.FL connector. Registered office: u-blox AG Zürcherstrasse 68 8800 Thalwil Switzerland [email protected] [email protected] UBXDOC-1023859458-41072 C3-Confidential 2/2 The module versions IRIS-W106-00B, IRIS-W106-10B, IRIS-W106-30B and IRIS-W166-00B and are equipped with an integrated antenna. On these module versions, the RF-port is not available for external antenna connection. 5. The modular transmitter must be tested in a stand-alone configuration Yes. The module was soldered onto the evaluation board EVB-IRIS-W1 and tested in a stand-alone configuration. The antenna trace reference design connecting the RF-port of IRIS-W101-00B, IRIS- W101-10B, IRIS-W101-30B and IRIS-W161-00B to a U-FL connector was implemented on the EVB-IRIS- W1 evaluation board. 6. The modular transmitter must be labelled with its own FCC ID number Yes. The module is labelled with its own FCC ID number. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. Yes. Detailed instructions to the module integrator are presented in the User’s Guide. 8. The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. Yes. The IRIS-W1 modules complies with the RF exposure limits when integrated into host devices categorized as mobile and/or portable. See separate document for RF exposure calculations.
