OEM Integrators Installation Manual

Important Notice to OEM integrators

1. This module is I’m ited to OEM installation ONLY.
2. This module is limited to installation in mobile or fixed applications, according to Part 2.1091(b).
3. The separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations
4. For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing to verify compliance as a composite system. When testing the host device for compliance with Part 15 Subpa rt B, the host manufacturer is required to show compliance with Part 15 Subpart B while the transmitter module(s) are installed and operating. The modules should be transmitting and the evaluation should confirm that the module’s intentional emissions are compliant (i.e. fundamental and out of band emissions). The host manufacturer 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 transmitter(s) rule(s).

Antenna Installation

1. The antenna must be installed such that 20 cm is maintained between the antenna and users
2. The transmitter module may not be co-located with any other transmitter or antenna.
3. To comply with FCC/IC regulations limiting both ma ximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile exposure condition must not exceed:

Peak gain of Antenna:

• 1.47dBi @ 2.412 GHz
• 1.64dBi @ 2.442 GHz
• 1.28dBi @ 2.462 GHz
• 4.58dBi @ 5.2GHz
• 4.37dBi @ 5.3GHz
• 3.68dBi @ 5.6GHz
• 3.50dBi @ 5.785GHz

In the event that these conditions cannot be met (for example certain laptop configurations or colocation with another transmitter), then the FCC/IC authorization is no longer considered valid and the FCC ID/IC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC/IC authorization.
