Uses Radio Waves at 2.4 and 5 GHz
Up To 100m Range
Has different catagories - 802.11 a/b - g - n and ac
Effective at creating small localized LANs]]> 2022-03-24 13:39:39 UTC https://padlet.com/adamhackney1/FactFiles/wish/2111876044 NFC https://padlet.com/adamhackney1/FactFiles/wish/2111876279 6cm range]]> 2022-03-24 13:39:46 UTC https://padlet.com/adamhackney1/FactFiles/wish/2111876279 NFC https://padlet.com/adamhackney1/FactFiles/wish/2111876668 NFC uses magnetic coupling to send and receive signals 
NFC has a range of roughly 6CM 
NFC range depends on the size of the antenna in the NFC enabled device. 
There are two main types of NFC devices, passive and active. 
They simply transmit data, unable to process it.

NFC transmissions are short range (from a touch to a few centimetres) and require the devices to be in close proximity.]]> 2022-03-24 13:40:33 UTC https://padlet.com/adamhackney1/FactFiles/wish/2111877973 IR https://padlet.com/adamhackney1/FactFiles/wish/2111878839 Requires 'Line of Sight'
Commonly use now on TV]]> 2022-03-24 13:40:58 UTC https://padlet.com/adamhackney1/FactFiles/wish/2111878839 Bluetooth https://padlet.com/adamhackney1/FactFiles/wish/2111879573
· Older Bluetooth signals used to only have a limit of 10 feet or so, newer signals can reach up to roughly 30 feet. However, the range will vary depending on obstacles (people, walls, etc).

  • There are five different versions of it. The first version was called 1.1, which was followed by 1.2, 2.0 plus EDR, 3.0 plus HB and version 4. They are backwards-compatible with Bluetooth devices.
·         The latest version lets a single device act as "master" and communicate with up to seven "slaves" at once.
·          In 2008, only 5% of mobile devices were Bluetooth-enabled. Compare that to today, when roughly 95% of mobile devices support it.
·         The protocol for Bluetooth allows it to be updated with ease.  These upgrades offer new features and are typically compatible with older forms.  Newer versions of the technology are currently being developed.

  1. Stands for “Near Field communication” 
  2. Range of ~ 4 cm 
  3. Low speed 
  4. Used for sharing small files, such as authentication tokens for contactless payment 
  5. Due to low power & proximity, little interference occurs from radio waves
