Modern wireless communication systems transmit voice and data without cables or wires. They use electromagnetic signals to broadcast data from sending facilities to intermediate and end-user devices. 

Some examples of wireless communication systems include:
Infrared (IR): A wireless mobile technology that uses infrared radiation to communicate data or information in devices or systems. IR communication has limitations because it requires line-of-sight, has a short transmission range, and is unable to penetrate walls.
5G: The newest 5th generation mobile wireless broadband technology based on the IEEE 802.11ac standard. 

Other examples of wireless communication systems include:
Television and radio broadcasting
Satellite communication
Radar
Mobile telephone system (cellular communication)
Global positioning system (GPS)
WLAN (Wi-Fi)
Bluetooth 

A wireless communication system typically consists of:
A transmitter
A receiver
A communication channel

Sometimes intermediary devices like repeaters or routers 
The transmitter converts information into a signal, which is then transmitted through the channel. 

Some examples of wireless devices include:
Cordless phones
TV remote controls
Radios
GPS systems
Phones
Tablets
Bluetooth mice and keyboards
Wireless routers 

Topics include: 2G Cellular Networks, 2.5G, 3G Wireless Networks, 3G W-CDMA (UMTS), 3G Cdma2000, WLANs, & Bluetooth / Personal Area Networks.
