If the mobile phone uses GPRS DTU on the Internet, data can be sent and received in groups, which means that users are always online and charged according to traffic, which quickly reduces the service cost. If CSD bearer is changed to GPRS, it means that dozens of people will bear the cost of the original one. Therefore, many unnecessary expenses will be greatly reduced.period radio Module Many adjustments have also been made, and the direction of product research and development has been reversed, in order to better meet the market demand. https://www.hkulike.com/
The advantage of GPRS DTU is that its data transmission speed is not comparable to that of GSM. At present, the transmission speed of GSM mobile communication network is 9.6K kilobytes per second, and the transmission speed of GPRS mobile phone has reached 56Kbps when it was launched at the beginning of this year, and now it has reached 115Kbps. Packet is to package Data into many independent packets, and then send these packets one by one, which is somewhat similar to sending a package. The advantage of packet switching is that it only takes up bandwidth when there is data to be sent, and it can be priced according to the amount of data transmitted, which is a more reasonable charging method for users, because most of the time and bandwidth of data transmission like the Internet are intermittent.
GPRS DTU can provide four different coding methods, which also provide different error protection capabilities. Using four different coding methods, each time slot can provide different transmission rates. Each user can use up to eight time slots at the same time. So GPRS DTU is called high transmission rate.
