3.10 Mobile Networks
Definition:

Mobile Networks are communication networks that allow mobile devices such as
smartphones, tablets, and laptops to communicate with each other and with other networks
without using physical wired connections. They enable users to make calls, send
messages, and access the internet while moving from one place to another. Mobile
networks are also known as cellular networks.

A mobile network is divided into small geographic areas called cells.

Each cell is served by a Base Station (BS) or Base Transceiver Station (BTS) that
communicates with mobile devices using radio signals. When a user moves from one cell to
another, the network performs a process called handover (handoff) to maintain the
connection.

3️.11 Main Components of Mobile Networks
Mobile Station (MS) The user device used to access the network.

• Smartphones
• Tablets
• Mobile modems

2. Base Station (BS or BTS)

The radio transmitter/receiver that connects mobile devices to the network.

Functions:

• Communication with mobile devices
• Radio signal transmission
• Managing local wireless connections

3. Base Station Controller (BSC)

Controls multiple base stations and manages:

• Radio resources
• Handover between cells
• Channel allocation

4. Mobile Switching Center (MSC)
