OEM integrators and installers are instructed that the phrase. This device contains transmitter FCC ID: O6Y-CDMRF101 must be placed on the outside of the host. Warning: Exposure to Radio Frequency Radiation The radiated output power of this device is far below the FCC radio frequency exposure limits. Nevertheless, the device should be used in such a manner that the potential for human contact during normal operation is minimized. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna should not be less than 20cm during normal operation. The gain of the antenna for Cellular band must not exceed 0dBi. The gain of the antenna for PCS band must not exceed -3dBi.

1 INTRODUCTION / OVERVIEW 1.1 MSM 6050 Chipset The MSM6050 CDMA2000 1X solution is optimized to support voice and key data capabilities while enabling CDMA2000 network benefits. Designed to support the CDMA2000 1X standard to address enhanced features as simultaneous voice and data applications and utilize network optimizations, the MSM6050 chipset will support packet data rates of 153 kbps on the forward and reverse links (FL and RL). It provides a seamless migration path from 2G to 3G services and applications, and the increased voice capacity of a CDMA2000 network. The MSM6050 solution will enable manufacturers to quickly develop handsets meeting specifications for worldwide cdmaOne™ and CDMA2000 1X systems. The MSM6050 CDMA 2000 1X solution will be used to build a phone module based solution where the module will be used in a telematics module for an automotive application. The phone module will be designed for use on the Verizon network. The phone module will not have the typical user interfaces common to handsets (i.e. keypad, display, etc.). The phone module will have an I/O connector and an RF connector. Likewise, the phone module will be designed to be certified by Verizon and FCC as a stand alone module meant for embedded applications. The MSM6050 chipset solution consists of the MSM6050 baseband processor, direct conversion RFR6155™ and RFR6000™ receive devices, the direct conversion RFT61500™ transmit device MAX8629™ power management device and a compatible power amplifier device. 1.1.1 MSM 6050 Features ■gpsOne position location capabilities (not enabled in this module) ■CDMA2000 1X support, offering data rates up to 153 kbps on the forward and reverse links ■Quad-mode (CDMA cellular, CDMA PCS, AMPS cellular, gpsOne) ■Vocoder support (EVRC, 13K QCELP) ■Fast 800 Hz forward power control ■Quasi-Orthogonal functions ■Supplemental channel (SCH) support ■CDMA2000 1X Forward Quick Paging channel (F-QPCH) ■Convolutional and turbo codes on SCH ■ITU 144 kbps requirements achieved ■153 kbps on FL and RL (aggregate) ■Integrated wideband mono voice CODEC
