What is packet data on mobile phone?
Packet Data – small pieces called packets. This allows users to consume a network’s resources only when they are actually transferring data. In mobile phones, data is used for functions requiring Internet access (including video or audio streaming).
What is CDPD in mobile communication?
Cellular Digital Packet Data (CDPD) was a wide-area mobile data service which used unused bandwidth normally used by AMPS mobile phones between 800 and 900 MHz to transfer data.
What are the protocols used in CDPD and explain?
The CDPD overlay network may use either the OSI ConnectionLess Network Protocol or Internet protocol (IP) at the network layer. These protocols have virtually the same functionality: They both interpret device names to route packets to remote locations.
What is CDPD explain how data communication is performed using CDPD?
Cellular digital packet data (CDPD) was a wireless data service used to access the Internet and other packet-switched systems over a cellular network. CDPD was normally used by analog advanced mobile phone system (AMPS) standards and was one of the first generation cellular frequencies.
What does a data packet do?
A data packet is a unit of data made into a single package that travels along a given network path. Data packets are used in Internet Protocol (IP) transmissions for data that navigates the Web, and in other kinds of networks.
How do I turn off packet data on Android?

What are data packets?
A packet is a bit of data that is packaged for transmission over a packet switched network. It is a small amount of data sent over a network, such as a LAN or the Internet. Similar to a real-life package, each packet includes a source and destination as well as the content (or data) being transferred.
Where are data packets used?
What is mobile data service?
Mobile data is internet content delivered to mobile devices such as smartphones and tablets over a wireless cellular connection. Mobile data plans offer varying amounts of data transfer per month for a range of rates.
Why are data packets needed?
It turns out that everything you do on the Internet involves packets. The packets carry the data in the protocols that the Internet uses: Transmission Control Protocol/Internet Protocol (TCP/IP). Each packet contains part of the body of your message. A typical packet contains perhaps 1,000 or 1,500 bytes.
