Problems solved by technology

GSM frequency resources are scarce in many areas. GPRS uses packet services, and each user occupies more frequency resources than voice, which leads to further shortage of GPRS frequency resources, thus limiting the number of GPRS data users.

There is also a relatively narrow transmission bandwidth, which cannot meet the defects of future video transmission
