Network: a system that connects devices so they can communicate.

Example: A mobile phone uses a network to send calls and data.

Cellular network: a mobile network divided into areas called cells.

Example: Cellular networks allow mobile phones to connect in different locations.

Multiple access: the ability of several users to use the network at the same time.

Example: Multiple access allows many calls in the same cell.

TDMA: a technology where users share the same frequency by using very short time slots.

Example: In TDMA, each call transmits during its own time slot.

GSM: an older mobile network technology mainly used for voice calls and SMS.

Example: GSM is based on TDMA technology.

Time slot: a very short period of time when a call or signal can be transmitted.

Example: TDMA divides transmission into time slots.

CDMA: a technology where several calls use many frequencies at the same time, but each call has a unique code.

Example: CDMA uses sequence codes to keep calls separate.

Sequence code: a unique code that identifies a call or signal.

Example: In CDMA, each call has a different sequence code.

Spread spectrum: a method of sending a signal across many frequencies.

Example: CDMA uses spread spectrum technology.

Interfere with: to disturb or disrupt the normal operation of something.

Example: Signals must not interfere with each other.

Encryption: the process of protecting information by converting it into code.

Example: GSM uses encryption to keep calls separate and secure.

LTE / 4G: a modern mobile network technology designed mainly for fast data transmission.

Example: LTE allows faster internet access on mobile phones.

5G: a newer mobile network technology with higher speed, lower latency and better capacity.

Example: 5G supports many connected devices at the same time.
