WIMAX

yeah... so our state going to be WI-FI free huh?

seems like they are making the WIMAX into Wi-Fi... haha, i used to think if i have a WI-FI phone, i can access WIMAX network.. look like i am SERIOUSLY WRONG... Diff frequency altogether... and comparing them it's like comparing apple to orange.

WiMax networks are similar to Wifi in deployment. The Wimax Base station/Tower will beam a signal to a WiMax Receiver. Similar to a WiFi access point sending a signal to a laptop. :) Understand? Look at the diagram below to better understand.............



QOS (Quality of Service) is an major issue with WiMax because of the number of people accessing a tower at once. Some would think that a tower could be easily overloaded with a lot of people accessing it at once. Built into the WiMax standard is an algorithm that when the tower/base station is nearing capacity then it automatically will transfer the user to another WiMax tower or cell. Unlike a Wifi clients who have to kind of fight to stay associated with a given access point; WiMax will only have to perform this hand shake at the MAC level the first time they access the network.

WiMax is designed for building a network infrastructure when the environment or distance is not favorable to a wired network. Also, WiMax is a cheaper and quicker alternative than having to lay wire. Third world countries will greatly benefit from deploying WiMax networks. WiMax can handle virtually all the same protocols Wifi can including VOIP. African countries are now going to start deploying WiMax networks instead of cell phone networks. Disaster zones can also utilize WiMax giving them the ability to distribute crisis information quickly and cheaply.

Militaries are already using wireless technology to connect remote sites. Logistics will be simplified with the ease of tracking with RF technologies. WiMax can also handle Webcams and streaming video which would give commanders eyes on target capability. Just imagine if planes were able to drop preconfigured self deploying WiMax antennas in strategic areas giving troops real time battlefield intel. Armed with wireless cameras, drones and a GPS one soldier would truly be an Army of One.

As WiMax is deployed in more areas theory and real life capabilities of WiMax will come to light. The differences between WiMax and Wifi are simple. Think of a WiMax network as an ISP with out wires, with the signal providing your internet access to your business/ home. Wifi will be used within in your LAN for the near future.

hahaha..reading until the end........ i think it simply means that now, it's better to get a WIMAX or Wi-Fi phone(since our government is converting the WIMAX into WI-Fi for us..).. and we can make free phonecall... YEAH~~~~~............ :D
