What is the 802.11 N protocol

  • Products adhering to IEEE 802.11n, the most recent revision to the standard, have the potential to transfer data at a rate up to ten times faster than those adhering to IEEE 802.11g, the previous wireless networking standard.
  • Manufacturers are instructed by the 802.11n standard on how to design their products in a way that ensures compatibility with those of other manufacturers.
  • Additionally, the IEEE 802.11n standard makes sure that newer products can still be used with older ones.
  • The range of 802.11n can reach three times that of wireless g.
  • The two frequency bands that 802.11n standard devices can use to operate are 2.4GHz and 5GHz.
  • 802.11n standard devices can reduce their data rate to improve the quality of the connection when the data quality deteriorates.
  • Products that adhere to the 802.11n standard are very secure.
  • As more and more new generation devices connect to existing networks and activities like high-speed interactive gaming and streaming music and video become more popular, 802.11n has been designed to meet the anticipated demand for faster access to more data.
  • An 802.11n access point can cover a large area, such as public areas in airports, and the 802.11n standard can support a wide range of network sizes, from small home WLANs to large enterprise networks.
  • 802.11ac: Only operates in the 5 GHz frequency range.
  • 802.11n: Uses the 2.4 and 5 GHz frequency bands for operation.
  • 802.11ac: Supports up to 8 spatial streams and makes use of beamforming technology for improved signal directionality.
  • 802.11n: Lacks explicit beamforming but supports up to 4 spatial streams using MIMO technology.
  • 802.11ac: 802.11ac supports higher data transfer rates of up to several gigabits per second (Gbps).
  • 802.11n: Slower than 802.11ac, it supports data transfer rates of up to 600 Mbps.
  • 802.11ac: Provides a longer range than 802.11n, especially when beamforming is used.
  • In ideal circumstances, an 802.11n Wi-Fi network connection can support up to 300 Mbps of rated theoretical bandwidth.
  • Wireless-N broadband routers and network adapters need to be connected and operating in a mode known as channel bonding mode in order for an 802.11n connection to function at its fastest possible rate.
  • In comparison to 802.11b/g, 802.11n uses bonding to simultaneously use two adjacent Wi-Fi channels to double the wireless link bandwidth.
  • Because channel bonding uses more spectrum and power, there is a greater chance that it will interfere with neighboring Wi-Fi networks.
  • Channel bonding is typically not enabled by default in 802.11n products.
  • The process for setting up channel bonding differs based on the product.
  • For the following reasons, 802.11n equipment may eventually be unable to operate in the maximum (300 Mbps) performance range:
