As with any wireless technology, the requirements for WiMAX are basically a transmitter and a receiver. The transmitter is a WiMAX tower, much like a GSM tower. One tower, also called a base station, can provide coverage to an area within a radius of around 50 km. There is nothing much you the consumer can do about that tower; it is the part of the service provider's facilities. So first, you need to get yourself subscribed to a WiMAX service. Here is a list of deployed WiMAX networks around the world, from which you can search for one closest to you. On the other side, in order to receive the WiMAX waves, you need a receiver for WiMAX for connecting your computer or device. Ideally, your device will have WiMAX support in-built, but that might be a bit rare and expensive, because the first WiMAX-enabled laptops have just been released and at the time of writing (2009), there are only a handful of WiMAX-enabled mobile phones, like the Nokia N810 Internet tablet. However, there are PCMCIA cards for laptops, which are quite affordable and convenient. We used to have a WiMAX modem that we'd connect to a laptop, but it happened to be quite inconvenient since it needed to be powered and it was less than easily portable. WiMAX modems can connect to computers and other devices through USB and Ethernet cables. What WiMAX Costs WiMAX is bound to be cheaper than both broadband DSL Internet and 3G data plans. We don't consider Wi-Fi here even if it is free because it is a LAN technology. WiMAX is cheaper than wired DSL because it does not require placing wires around the area to be covered, which represents an enormous investment for the provider. Not requiring this investment opens the door to many service providers who can start retailing out wireless broadband with low capital, thereby causing prices to drop due to competition. 3G is packet-based and users normally have a threshold package. Data transferred beyond the limit of this package is paid per excess MB. This can end up being quite expensive for heavy users. On the other hand, WiMAX allows unlimited connectivity for all kinds of data, including data, voice, and video. If you intend to use WiMAX, you will only have to invest in WiMAX-supported hardware or device that will connect to your existing hardware. In these early days of WiMAX integration, the former will be expensive, but the latter quite affordable and even free. When we subscribed to a WiMAX service some time back, we were given a modem free of charge (to be returned at the end of the contract). We only had to pay the monthly fee, which was a flat rate for unlimited access. So finally, WiMAX, especially at home and in the office, can be relatively quite cheap. WiMAX Performance WiMAX is quite powerful, with a speed of up to 70 Mbps, which is a lot. Now, what comes after determines the quality of the connection you receive. Some providers try to accommodate too many subscribers on one line (on their servers), which results in poor performances during peak times and for certain applications. WiMAX has a range of around 50 km in a circle. Terrain, weather, and buildings affect this range and this often results in many people not receiving signals good enough for a proper connection. Orientation is also an issue, and some people have to choose to place their WiMAX modems near windows and turned in certain specific directions for good reception. A WiMAX connection is normally non-line-of-sight, which means that the transmitter and the receiver need not have a clear line between them. But a line-of-sight version exists, where performance and stability is much better, since this does away with problems associated with terrain and buildings. .
