1 Introduction MWMII (Masimo Wifi Module II) contains an Azureware AW-CM256SM radio module, which incorporates the Broadcom BCM43455 radio chip. It offers IEEE 802.11 a/b/g/n WIFI with Bluetooth 4.2. The Wifi radio uses a 50MHz SDIO interface and the Bluetooth radio uses a 3MBaud UART interface. MWMII has 32.768 kHz Oscillator and 37.5 MHz crystal along with the u. Fl. connector.
Note: In accordance with international telecommunication requirements, the frequency band of 2.4 GHz and 5.15 to 5.25 GHz is only for indoor usage to reduce potential for harmful interference to co-channel mobile satellite systems. Note: To satisfy RF exposure requirements, this device and its antenna must operate with a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.
