Topic 16 - Wireless Connection Method Flashcards
What do wireless methods connect using?
Wireless connection methods connect using
the electromagnetic spectrum.
This may be traditional radio waves or even light waves
What is the use of WIFI? (Wireless system connection methods)
Use = To connect devices wirelessly to local and wide area networks such as the internet
3 Advantages of WIFI
High data transfer speeds
Good range
Relatively cheap to install
2 Limitations of WIFI
Can be complex
Security concerns
What is the use of 3G/4G/WiMAX? (Wireless system connection methods)
Use = To connect to data networks such as the internet whilst on the move
2 Advantages of 3G/4G/WiMAX
Allows true mobility
4G provides for very fast connection speeds
2 Limitations of 3G/4G/WiMAX
Heavey data usage can be costly
Uses public networks
What is the use of Satellite broadband? (Wireless system connection methods)
Use = Provides connectivity to remote areas, often rural
2 Advantages Satellite broadband
Wide converage
High speed
2 Limitations of Satellite broadband
High latency
Subject to weather conditions

What is the use of Bluetooth? (Wireless connection methods for devices)
Use = For paiting devices over short distences, such as wirless headphones, watches, keyboards and mice
2 Advantages of Bluetooth
Easy to set up
Low power consumption
2 LImitations of Bluetooth
Low data transfer speeds
Very short range
What is the use of WIFI Direct? (Wireless connection methods for devices)
Use = For connecting devices to remote displays
2 Advanatges of WIFI Direct
Can transmit both audio and video
Usually built in to devices
2 Limitations of WIFI Direct
Limited range
Can affect data connectivity (interference)
What is the use of WIFI? (Wireless connection methods for devices)
Use = Allows ‘ad-hoc’ networks to permit wireless printing/scanning
2 Advantages of WIFI
SImple setup
Uses existing WiFi infrastructure
1 Limitation of WIFI
Using as-hoc networks can impact connectivity
