Hello, everyone!
Today, I would like to share with you an article on cellular backhaul usage scenario in WiMAX technology.
Based on its technical attributes and service classes, WiMAX is suited to supporting a large number of usage scenarios as it revolutionizes the way we communicate. It provides total freedom to people who are highly mobile, allowing them to stay connected with voice, data and video services.
Table 1. WiMAX Ranges of Applications
To illustrate the ability of WiMAX to address the applications outlined in the above Table 1, the cellular backhaul usage case scenario is outlined in the below Table 2.

Cellular Backhaul
Majority of backhaul is done by leasing E1 services from incumbent wire-line operators. With the WiMAX technology, cellular operators will have the opportunity to lessen their independence on backhaul facilities leased from their competitors.
Outside the United States, the use of point-to-point microwave is more prevalent for mobile backhaul, but WiMAX can still play a role in enabling mobile operators to cost-effectively increase backhaul capacity using WiMAX as an overlay network as depicted in the below Figure 1.
Figure 1. Cellular backhaul with WiMAX
This overlay approach will enable mobile operators to add the capacity required to support the wide range of new mobile services they plan to offer without the risk of disrupting existing services.
Some salient points about WiMAX usage in cellular backhaul are:
• High capacity backhauls.
• Multiple cell sites are served.
• There is capacity to expand for future mobile services.
• It is a lower cost solution than traditional landline backhauls.
