What type of technology does General Packet Radio Service (GPRS) replace?

General Packet Radio Service (GPRS) is a technology that was introduced to enhance the capabilities of mobile communication networks, allowing for the transmission of data in a more efficient manner. GPRS is specifically designed to provide packet-switched data services, which are essential for the efficient handling of internet and multimedia services over mobile networks.

The correct answer indicates that GPRS replaces Cellular Digital Packet Data (CDPD) technology. Before GPRS, CDPD was used to facilitate packet-switched data transmission. However, GPRS offers significant improvements over CDPD, particularly in terms of speed, volume, and data handling capabilities. It allows users to send and receive higher volumes of data more rapidly and reliably, making it better suited for modern mobile data demands, such as web browsing and email.

In the context of the other options, while GPRS relates to mobile communications, it doesn't replace Wireless Local Area Networks, Analog Signal Processing, or Wide Area Network Technology in the same manner as it does with CDPD. Each of the alternatives represents different aspects or layers of telecommunications technology. Wireless Local Area Networks focus more on short-range communication, Analog Signal Processing pertains to the conversion and transmission of analog signals, and Wide Area Network Technology encompasses broader networking solutions rather than specific mobile packet
