1The design of the Wimax is ideal ___ challenges related with earlier versions of wired and wireless access networks. ___ the same time the backhaul connects the WiMAX system to the network, it is not an integrated part of WiMAX system. Normally a WiMAX network consists ___ two parts, a Wimax Base Station (BS) and a Wimax receiver also referred as Customer Premise Equipment (Wimax CPE).
2A Wimax base station comprises ___ internal devices and a Wimax tower. A Wimax base station can normally cover the area ___ about 50 kilometres or 30 miles radius, but some other and environmental issues bound the limits of Wimax range ___ 10 km or 6 miles. Any wireless user ___ the coverage area would be able to access the Wimax services. The Wimax base stations would use the media access control layer defined ___ the standard and would allocate uplink and downlink bandwidth to subscribers according to their requirements ___ real-time basis.
3A Wimax receiver, which is also referred as Customer Premise Equipment (Wimax CPE), may have a separate antenna or could be a stand-alone box or a PCMCIA card inserted ___ a laptop or a desktop computer. Access ___ a Wimax base station is similar to accessing a wireless access point (AP) in a Wi-Fi network, but the coverage is more.
4So far one of the biggest restrictions ___ the widespread acceptance ___ WiMAX has been the cost of Wimax CPE (Wimax Receiver). This is not only the cost ___ Wimax CPE (Wimax Receiver) itself, but also that of installation. In the past, Broadband Wireless Access (BWA) was predominantly Line Of Sight (LOS), requiring highly skilled labour and a truck role to install and provide a service ___ customer. The concept of a self-installed Wimax CPE (Wimax Receiver) has been difficult ___ BWA ___ the beginning, but ___ the advent of WiMAX technology this issue seems to be getting resolved.
