Question

Assume you have a wireless network of 90m coverage and this network is connectionless oriented. There are two networks topology (WIFI or WIMAX). Critically analyse the given networks and answer the following:
1- Compare between WIFI and WIMAX
2- Which are of them is better to be used in this case

Answer 1

1)Comparing WIFI and WIMAX in the below table according to property.

Key	WIFI	WIMAX
Abbrevation	WIFI stands for Wireless FIdility	WIMAX stands for Worldwide Interoperability for Microwave Access
IEEE Standards	Wi-Fi has been defined under IEEE 802.11x standards where x is various Wi-Fi versions.	WiMAX is standardized under 802.16y family of wireless networking where y refers to various WiMAX versions.
QOS	Does not offer	WiMax guarantees Quality of Service, QoS.
Versions	802.11b, 802.11g, 802.11n.	802.16a, 802.16d and 802.16e
Network Range	An Ideal WIFI covers an range of max 100 meters	WiMAX network can reach about 80-90kilometers
Bandwidth	20Mhz	1.25 to 20Mhz
Nework Layer Protocol	CSMA/CA	Connection Oriented
Encryption	Advanced Encryption Standard (AES) and RC4	Triple Data Encryption Algorithm and Advanced Encryption Standards.
Aunthentication	Wi-Fi uses Extensible Authentication Protocol (EAP) Wired Equivalent Privacy (WEP) security algorithms depending on the Wi-Fi version.	WiMAX uses X.509 or PKMv2 as authentication algorithms.

Application of WIFI: Since the wifi can cover only limited distance this widely used in creating local wireless networks connection households, businesses etc.

Application of WIMAX: WiMAX serves a larger inter-operable network. WiMAX can be used to provide internet services to a larger area where it can serve households, mobile phones and even Wi-Fi spots.

2) An Ideal WIFI with a powerful wireless Router, tit can cover a range of 100 Meters. So it is better to use WIFI in this case.
