With a compact profile of 29.0mm × 25.0mm × 2.3mm, EG91 series module can meet almost all
requirements for M2M applications such as automotive, smart metering, tracking system, security, router,
wireless POS, mobile computing device, PDA phone, tablet PC, etc.
EG91 series module is an SMD type module which can be embedded into applications through its 106
LGA pads.
EG91 series module is integrated with internet service protocols like TCP, UDP and PPP. Extended AT
commands have been developed for customers to use these internet service protocols easily.
