6.1 CC33xxMOD OEM Integration Manual

Important Notice to OEM integrators

  1. This module is limited to OEM installation ONLY.
  2. This module is limited to installation in mobile or fixed applications, according to Part 2.1091(b).
  3. Refer to the datasheet for the device for trace design instruction. As a module using trace design, this module relies on the manufacturers of the host product to prepare the antenna connector. A unique antenna connector must be used on the Part 15 authorized transmitters used in the host product. The module manufacturer provides a list of acceptable unique connectors (see Table 6-4).
  4. Separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations.
  5. For FCC Part 15.31 (h) and (k): The manufacturer of the host product is responsible for additional testing to verify compliance as a composite system. When testing the host device for compliance with Part 15 Subpart B, the manufacturer of the host product is required to show compliance with Part 15 Subpart B while the transmitter module (or modules) are installed and operating. The modules must be transmitting, and the evaluation must confirm that the intentional emissions of the module are compliant (for example, fundamental and out of band emissions). The manufacturer of the host product must verify that there are no additional unintentional emissions other than what is permitted in Part 15 Subpart B or emissions are complaint with the rules of the transmitter (or transmitters).

Antenna Installation

  • (1) The antenna must be installed such that 20cm is maintained between the antenna and users.
  • (2) The transmitter module cannot be co-located with any other transmitter or antenna.
  • (3) Only antennas of the same type and with equal or less gains (see Table 6-4) can be used with this module. Other types of antennas and higher gain antennas possibly require additional authorization for operation.
