Fm Radio & Bluetooth & Wlan - LG GM360i Service Manual

GM360i Operational Description
3.14 FM radio & BLUETOOTH & WLAN
General Description
The GM360ii device provides the highest level of integration for a mobile wireless system, with
integrated IEEE802. 11 b/g(MAC/baseband/radio), Bluetooth 2.1, and FM receiver. The LBEH19UNBC that is
included of BCM4325 solution is supported three kinds of functions. It is the one antenna structure which is
supported of WLAN/Bluetooth in 2.4GHzand
3.14.1 WLAN
The GM360ii supports single-band 2.4GHz IEEE802.11b/g standardization. The WLAN module which is
consisted of the BCM4325 single chip device provides for the highest level of integration for a mobile or
handheld wireless system, with integrated IEEE802.11TM b/g (MAC/baseband/radio). The BCM4325's
integrated CMOS WLAN 2.4GHz power amplifier provide sufficient output power to meet the need of most
WLAN devices. The interface between PMB8878 and WLAN module is the standard interfaces SDIO v1.2 (4-bit
and 1-bit). [Figure3.14] shows the WLAN system architecture in the GM360ii
3.14.2 Bluetooth
The GM360ii provides the Bluetooth 2.0 specification. The Bluetooth module is the optimal solution for any
voice or data application that requires the Bluetooth SIG standard Host Controller Interface (HCI) using a
high-speed UART and PCM. The Bluetooth solution has an integrated radio transceiver that has been optimized
for 2.4GHz Bluetooth wireless systems. It has been designed to provided low power, low-cost, robust
communications for applications operating in the globally available 2.4GHz unlicensed ISM band. It is fully
compliant with the Bluetooth Radio Specification and meets or exceeds the requirements to provide the
highest communication link quality of service. [Figure3.14] also shows the Bluetooth system architecture in the
GM360ii.
