What is a Wimax network?
What is a WiFi network?
What is a GSM or CDMA network?
First i have to know what are those different type of networks what are the basic definition and difference between them.
I basically understand that in cell phone network mainly GSM and CDMA is used and some Mobile operators supports WiFi technology. But i have no clear idea of how it is done and what are the differences. All those network are wireless and works on signals or frequencies. But not all device supports all type of frequencies that's why mobile and modem are required.
This is my experience but I don't know how does it work. So I will be glad if someone can explain it with some examples and definitions that I will be easy to understand.
Best of luck. See you.

What are the basic difference between Wimax , WiFi and Gsm system???
All those networks are wireless technologies and works on signals or Microwave frequency range to offer wireless access. They use different parts of the radio frequency spectrum. Wi-Fi is in an unregulated part of the spectrum and Wi-Max is in a regulated part of the spectrum.
Wi-Fi is only operable in short ranges (250m radius) and Wi-Max in long ranges (30km radius).
Wi-Fi is a wireless LAN technology and Wi-Max is a wireless WAN technology
Wi-Max (Wireless Interoperability for Microwave Access)
It is a 4th generation high speed mobile access technology. Wi-Max has fixed and mobile version which can be used for applications with higher bandwidth(40Mbps). The fixed Wi-Max version is used for broadband solutions for homes. Also it can be used for back hauling remote offices or mobile stations. The Wi-Max mobile version is used as the replacement of GSM and CDMA technologies. Wi-Max is a cable broadband replacement in rural areas where copper network cannot be provided. Wi-Max can offer the triple play service of voice, video and data easily. The newest version of the Wi-Max is now equivalent to fiber network and very useful to provider access stations or remote offices. Wi-Max is mostly deployed by service providers with outdoor coverage and service for 1000 users.
Wi-Fi (Wireless Fidelity)
It’s a most common wireless technology in western countries used for Hotspots, homes and corporate internal wireless networks. Simply can say it got indoor coverage and up to 100 users service. When setting up a Wi-Fi at home, you have to make sure that you enable the security features such as Secure Wireless Encryption, MAC address filter. etc for avoid 3rd party access. Also don’t forget to change the default password of your wireless router. Wi-Fi is mostly an end user technology where users can purchase Wi-Fi devices and configure them by themselves.
GSM(Global System for Mobile Communications)
Well when you take the G technology as you said GSM 2G technology, 2nd generation digital cellular technology will allow data to be transmitted over mobile devices. End users with 2G devices connect to wireless cell sites up to 2Mbps with coverage several kilometers. The great advantage of using this technology is mobility but very slow and expensive as disadvantages.

Comparison Matrix
I think now you can clearly see the difference between them. Each network is used for a different purpose according to their features.

WIMAX is a wireless industry for broadband wireless network which is commonly known as 4G network and WIFI the wireless local area network and it uses access point or routers. As well aforementioned solutions also Check out this Techyv page for more information about this.

WiMAX stands for “Worldwide Interoperability for Microwave Access.” It is a wireless industry coalition committed to the advancement of the IEEE 802.16 standards for broadband wireless access networks or BWA and supports nomadic, mobile, and fixed wireless applications. In this context, a mobile user is like someone in transit like a commuter on a train.
A nomadic user is someone that connects on a portable device but does it only while stationary. An example of a nomadic user is when you connect to an office network from a hotel room. Fixed wireless, on the other hand, normally refers to wireless connectivity among non-mobile devices in businesses or in homes.
WiMAX is expected to provide around 10 Mbps both upload and download at a distance of ten kilometers (10 km) from a base station. According to the WiMAX forum, the group’s objective is to encourage and verify compatibility and interoperability of devices based on the 802.16 specification as well as to develop devices for the marketplace.
Wi-Fi is a term used for certain types of WLANs or wireless local area networks that implement specifications in the 802.11 series. A Wi-Fi network uses radio waves to transmit information wirelessly over a local area network. A computer that connects to Wi-Fi uses a wireless adapter or a Wi-Fi adapter to translate data transmitted by radio waves.
