Difference between Wi-Fi and WiMax

WiMax is similar to the wireless standard known as Wi-Fi, but on the much larger scale and at faster speeds.
A nomadic version would keep WiMax enabled devices connected over large areas much like today cellphones.This article will explore about the various difference between Wi-Fi and WiMax, So now we can compare it with Wi-Fi based on the following factor to details about Wi-Fi and WiMax.

Difference :
  • Wi-Fi was officially launched in the year of 1997, In WiMax Official release in the year of 2004.
  • Wi-Fi stands for "Wireless fidelity" and WiMax stand for "world wide interperability for microwave access".
  • Wi-Fi is based on format IEEE 802.11 standard, whereas WiMax is based on IEEE 802.16. Both are standards.
  • WiMax coverage range upto 30 miles and Wi-Fi coverage range upto is very limited to small area.
  • Wi-Fi provides a few hundred feet with speed of up to 54 Mbps on the other hand WiMax is provided range up to 40 miles with speeds of 70 Mbps or more.
  • Wi-Fi work at 2.7 bps/ Hz and can peak up to 54 Mbps in 20 MHz channel, Whereas WiMax work at 5 bps/Hz and can peak up to 100 Mbps in a 20 MHz channel.
  • In Wi-Fi user scale from one to tens with one subscriber for each consumer premises equipment ( CPE ) device. Fixed channel size 20 MHz, wheres WiMax is designed to efficiently from one to hundred of consumer premises equipment, with unlimited subscriber behind each CPE. Flexible channel size from 1.5 MHz to 20 MHz.
  • In Wi- Fi communication range up to 100 meters, WiMax communication range up to 40 km.
  • In WiMax include triple data encryption algorithm and advance encryption standards, while Wi-Fi, used encryption techniques are advanced encryption standard (AES) and RC4.
  • Wi-Fi does not guarantee any QoS but WiMax will provide your several levels of QoS.
  • Wi-Fi uses connection-based or connection-less protocol called CSMA/CA while WiMax uses MAC protocol which is connection oriented.
  • Most important point is that why we have not used in WiMax in home because Wi-Fi is much better speed and technology.
  • WiMax offer high speed internet as a broadband access which is transfer voice, video, at very high speed same way Wi-Fi offer short range of data transfer.
  • Wi-Fi access point transport signal to the receiving mode same way WiMax will beam a signal to receiver.
