Here's how communication takes place using a mobile voice network: a) Explanation of communication using a mobile voice network: 1. When the Sender initiates a call, their mobile phone converts their analog voice into digital signals. 2. These digital signals are then modulated onto radio waves and transmitted wirelessly to the nearest base station (cell tower). 3. The base station receives the radio signals and forwards the digital data through a wired connection (like fiber optic cables) to the Mobile Switching Center (MSC) in the cellular network. 4. The MSC identifies the Receiver's phone number and determines its current location within the network. 5. If the receiver is on the same mobile network, the MSC routes the call directly. If the receiver is on a different mobile network or a landline, the MSC routes the call through the Public Switched Telephone Network (PSTN) to the appropriate network. 6. The call eventually reaches the MSC serving the receiver's location. This MSC then sends a signal to the base station nearest to the receiver's phone. 7. The base station transmits radio waves to the receiver's mobile phone, causing it to ring. 8. Once the receiver answers, their phone converts the incoming digital signals back into analog voice, allowing the conversation to take place. The process is reversed for the receiver's voice to reach the sender. b) Identified components: 1. Sender: The person initiating the mobile phone call. 2. Receiver: The person receiving the mobile phone call. 3. Transmission medium: Wireless (radio waves)* between the mobile phones and the base stations. Wired (fiber optic cables, copper lines)* between base stations, Mobile Switching Centers (MSCs), and the Public Switched Telephone Network (PSTN). 4. Type of network used: A cellular network (mobile voice network) which integrates with the Public Switched Telephone Network (PSTN). That's 2 down. 3 left today — send the next one.
