1. Overview

    KB3021 Embedded GPRS Modem is wireless data transmitting terminal of GPRS and embedded with high reliable ARM7 CPU.   KB3021 is the smallest Embedded GPRS DTU in the market, the small size is very convenient to embedded for user's communication with low cost. The working Frequency adopt 850MHz/900MHz/1800MHz/1900MHz which is suit for every country all over the world (Including North America and South America);      

    KB3021 Embedded GPRS DTU is used in electric power automatic system, industry monitoring, traffic management, atmosphere, pro-environment, pipe network monitoring, finance, securities departments and so on. Consider the networking request from different application scope, achieve Virtual data private network in network structure. It is applicable to small and medium data transmitting of the Center to multi-points, multi-points scatter .
