MeiG-SLM900
Multi-network Smart LTE Module
Support for Wi-Fi & BT functionality
The equipment under test (EUT) is the smart module of Model SLM900(Model name).
It supports Triple-bandGSM/GPRSsolution(GSM850 ,PCS1900),GPRS/EDGE Class 12
Triple-band UMTS (B2,B4,B5)HSDPA（Category 24）,HSUPA（Category 6）also
supportsIEEE802.11a/b/g/n/ac，Bluetooth version2.1+EDR,BT3.0+EDR,BT5.0,GPS
operating frequency is 1.57542GHz.
The Qualcomm device incorporates the UMTS/LTE technology — the technology for RF
transceivers(SDR660) that converts received signals directly from RF-to-baseband and
transmits signals directly from baseband-to-RF (known as direct conversion or zero
intermediate frequency (ZIF) processing). This technique eliminates the need for large IF
surface acoustic wave (SAW) filters and supporting IF and LO circuits, thereby reducing the
handset parts count and facilitating multiband, multimode handsets that can be produced in
smaller form factors.
RF transmitter
The RF transmitters are capable to perform as well as UMTS and HSPAmodulation signals
with excellent noise performance, thus no interstate filter in between transceiver and PA is
required:
Triple-band UMTS, with one low band and two high bands selected from:
Low band
Band 5 (826 to 836 MHz)
High band
Band 2 (1852 -1907 MHz)
Band 4 (1712 -1752 MHz)
Triple-band GSM
Low band
– GSM 850 (824 to 849 MHz)
High band
– PCS 1900 (1930 to 1989 MHz)
