M95 Hardware Design
M95_HD_V1.0 - 15 -
2. Product concept
M95 is a Quad-band GSM/GPRS engine that works at frequencies of GSM850MHz,
GSM900MHz, DCS1800MHz and PCS1900MHz. The M95 features GPRS multi-slot class 12
and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. For more details about
GPRS multi-slot classes and coding schemes, please refer to Appendix A and Appendix B.
With a tiny profile of 19.9mm × 23.6mm × 2.65mm, the module can meet the requirements of
almost all M2M applications, including Tracking and Tracing, Industrial PDA, Wireless POS,
Intelligent Measurement, Remote Controlling, etc.
M95 is an SMD type module with LCC package, which can be embedded in customer applications.
It provides abundant hardware interfaces between the module and customer’s host board.
Designed with power saving technique, the current consumption of M95 module is as low as 0.9
mA in SLEEP mode when DRX is 5.
M95 is integrated with Internet service protocols, which are TCP/IP, UDP, FTP and PPP.
Extended AT commands have been developed for customer to use these Internet service protocols
easily.
The module fully complies to FCC statements and RoHS directive of the European Union.
