- Radio
Wireless Security

Wireless Technologies

Wireless: without wires
Mobile: changes location over time
Wireless networks can be both mobile (e.g., MiFi) and fixed (e.g., microwave towers).
Mobile computing: real-time wireless connection between mobile devices and environments (e.g., internet, intranet).
Mobile commerce (m-commerce): e-commerce transactions conducted using mobile devices.
Internet of Things (IoT): ubiquitous computing where virtually every object has processing power and wireless or wired connections to a global network.

Wireless Devices

Advantages for users:
- Small enough to carry
- Sufficient computing power
- Wireless communication
Disadvantage for businesses:
- Workers capturing and transmitting confidential/proprietary information

Wireless Transmission Media

Wireless media (broadcast media): transmit signals without wires.
