1 Overview

KB3021 Embedded GPRS DTU (Data Terminal Unit) 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);
