A.As for the use environment of WIFI, wireless signals are easily affected by the surrounding environment. For example, obstacles such as trees and metals will absorb wireless signals to some extent, so that the distance of data transmission is affected to some extent in practical applications. B.It is recommended that the metal enclosure be not installed in the metal enclosure as it is shielded from radio frequency signals. C.
(OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module. For 15 B (§15.107 and if applicable §15.107) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating. Furthermore the module should be transmitting and the evaluation should confirm that the module's intentional emissions (15C) are compliant (fundamental / out-of-band). Finally the integrator has to apply the appropriate equipment authorization (e.
SHENZHENSHI XINZHONGXIN TECHNOLOGY CO., LTD. C-3031U V1.4 Module statement The single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of § 15.212(a)(1) as summarized below. 1) The radio elements have the radio frequency circuitry shielded.
