M80 Hardware Design
M80_HD_V1.2 - 16 -
2. Product concept
M80 is a Quad-band GSM/GPRS engine that works at frequencies of GSM850MHz,
GSM900MHz, DCS1800MHz and PCS1900MHz. The M80 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 23mm×25mm ×2.6 mm, the module can meet almost all the requirements for
M2M applications, including Tracking and Tracing, Monitor and Security System, Wireless POS,
Intelligent Measurement, Industrial PDA, Remote Controlling, etc.
M80 is an SMD type module with LGA package, which can be embedded in customer’s
applications. It provides abundant hardware interfaces between the module and customer’s host
board.
Designed with power saving technique, the current consumption of M80 is as low as 1.1 mA in
SLEEP mode when DRX is 5.
M80 is integrated with Internet service protocols, which are TCP, UDP, FTP and PPP. Extended
AT commands have been developed for customer to use these Internet service protocols easily.
The module fully complies to the RoHS directive of the European Union.
