Summary - Unit 1 - Regulation of Communication Waves

Satellite

 Power mode =
 Frequency band = C-band (4-8GHz/gigahertz).
 Uses = they help us talk to each other and stay connected.
= monitor the weather (weather forecasting).
= monitors climate change.
= television signal.
 Regulated for?

Mobile Phones

 Power mode = this option reduces the devices performance, limits vibrations, location services
and most of the background data.
 Frequency band = 2G (voice calls, short messages).
3G (video conferencing, mobile TV, GPS).
4G (high speed applications, mobile TV, wearable devices).
5G (high resolution video streaming, remote control of vehicles, robots, and medical
procedures).
 Uses = communication via voice, messages and mails.
 Regulated for?

Bluetooth

 Power mode =
 Frequency band = 2.4GHz.
 Uses = is wireless and uses a radio frequency to share data over a short distance, eliminating the
need for wires.
 Regulated for?

WIFI

 Power mode = is a built-in mode that lets devices save power by monitoring the Wi-Fi's
impact on the device's battery life over time and evaluating the data usage patterns over time.
 Frequency band =
 Uses = provides wireless broadband internet access for many modern devices (such as laptops,
smartphones, tablet computers and electronic gaming consoles).
 Regulated for?

Infrared

 Power mode =
 Frequency band = 300GHz to 400THz.
 Uses = electrical heaters, cookers for cooking food, short range communications like remote
control, optical fibres, security systems and thermal imaging cameras.
