systems that can be upgraded from cdmaone to smooth. The route of its evolution is Cdmaone--cdma20001x--cdma20001xev. Another mainstream of the third generation of communication technology is the second generation of GSM standard developed by the WCDMA technology, because GSM uses TDMA (time division Multiple Access) modulation mode, and WCDMA uses CDMA (Code Division Multiple Access) modulation, its air channel is not compatible, Using the machine station stacking and the way of using multimod

GPRS: A new opportunity for the development of wireless internet

GPRS provides a seamless, direct Internet connection. GPRS supports X.25 protocols and IP protocols that have far-reaching implications for the Internet. GPRS is a supplement rather than a substitute for the existing circuit-switched data Service (CSD) and short Message Service (SMS) in GSM network. GPRS can dynamicall

Working principle and main features of GPRS

After the emergence of the GSM network, technicians quickly embed the GSM module into various instruments, such as multi-function Electric Energy Meter, fault recorder, meter reading

Essence and debugging experience of gprs dtu Communication

Reproduced (http://jingyan.baidu.com/article/219f4bf7d1f284de442d3823.html) Essence of DTU Communication The most basic usage of gprs dtu is to add a SIM card for activating the GPRS function in DTU. After DTU is powered on, it first registers to the GPRS network, and then establishes a connection with the data processing center through the

The application of Sybase database in Sichuan GPRS system

I. BACKGROUND With the rapid development of communications technology, our business activities cover new content, put forward new requirements, mobile communication technology began to approach business. And now the mobile communication system is also undergoing great changes, the application of a wide range of GSM communication network is to the third generation of mobile communication system, and GPRS is its necessary transition stage. As a result,

Concept of gprs dtu and working principle of DTU

Source: http://blog.csdn.net/bichenggui/article/details/7889638 Recently, a data center solution based on grps dtu data transmission needs to be developed, so I found some materials.
