Date: 2019-02-15 Cover Letter for re-use of Test Data To Whom It May Concern: The initial application has been granted according to 47CFR Part 15 for FCC ID: PZWBHT1700BQL; Granted on 01/02/2019. The new equipment to be Granted in this new application, according to FCC ID: PZWBHT1800QG, only differs from the initial version (FCC ID: PZWBHT1700BQL) with the only 3 following points: 1. Different antenna Please refer to the Internal Photos exhibits 2. Enclosure are different Please refer to the External Photos exhibits 3. Additional WWAN chip Please refer to the Internal Photos and Block Diagram exhibits The 3 changes described above do not affect the conducted test item (2.4G WLAN/BT) of the equipment. Consequently, the WLAN/BT conducted test data retrieved from the initial application FCC ID: PZWBHT1700BQL can be re-used for the FCC ID: PZWBHT1800QG equipment. However, Based on our knowledge and our engineering judgment of the device design, the changes made, the format and amount of spot–check test data are decided as below, 1. Sample amount: 1 2. Spot–check rule part, frequency band and test items 3. Spot–check measurement result refer to the test report of FCC ID: PZWBHT1800QG equipment.

The associated 47 CFR Part 15 tests reports (initial & new versions) are described in the following table: FCC ID: FCC ID: PZWBHT1700BQL PZWBHT1800QG Spot check Test Item (Worst channel) (initial) (new) 47CFR Part 15C 47CFR Part 15C 1.
