• Parcel Delivery: Handling and transport of packages of various sizes and weights.
• Document Delivery: Secure and swift transport of important papers, contracts, and confidential documents.
• Tracking Services: Allowing senders and recipients to monitor the status and location of their consignment in real-time.

Global System for Mobile Communication (GSM)

GSM stands for Global System for Mobile Communication. It is a digital mobile telephony system that is widely used around the world. GSM allows mobile phones to communicate by transmitting and receiving data over a network of base stations.

Advantages of GSM

The following are advantages of GSM:

• Widespread Coverage: GSM networks are available in most parts of the world, allowing for international roaming.
• Security Features: Provides good security for calls and data through encryption.
• SIM Card Technology: Allows users to easily switch phones by simply moving their SIM card.
• Voice and Data Services: Supports both voice calls and data services like SMS, MMS, and internet access.
• Cost-Effective: Generally offers competitive tariffs for calls and data.

Disadvantages of GSM

The following are disadvantages of GSM:

• Data Speed: Older GSM networks offered slower data speeds compared to newer technologies like 3G, 4G, or 5G.
• Network Congestion: Can experience network congestion in densely populated areas, leading to dropped calls or slow data.
• Interference: Can be susceptible to interference from other electronic devices.
• Battery Consumption: Continuous searching for network signals can sometimes drain phone battery faster.
