General Packet Radio Service (GPRS) has indeed replaced Cellular Digital Packet Data (CDPD) due to its capabilities that significantly improve speed and accuracy in mobile data transmission. GPRS enhances the efficiency of data handling in mobile networks by allowing for packet-switched data transmission. This technology operates by splitting data into smaller packets that can be sent across the network, which ensures faster and more efficient communication compared to the circuit-switched methods commonly used in previous generations of mobile communication.
The move to GPRS not only enables higher data transmission rates—thereby making it suitable for various applications like mobile internet browsing and multimedia messaging—but also supports better network utilization, as it allows multiple users to share the same channel without requiring a dedicated line for each call or data session.
In contrast, other options like Wireless Application Protocol (WAP) primarily serve as a protocol for delivering internet content to mobile devices rather than directly replacing older wireless technologies. Personal Digital Assistants (PDAs) refer to handheld devices and are not a wireless technology in the same context. Global System for Mobile Communications (GSM) is a standard for 2G mobile networks but is more related to voice services than to the data packet services provided by GPRS. Thus, GPRS is recognized as
