WiMax can be used with some of the 4G technologies to convert local area networks into metropolitan area networks; this would provide wireless connectivity to entire city. It is founded on the standards of IEEE 802.16. If we try to deploy WiMax at large scale, it is possible to provide broadband wireless access to both business and home users at economical rates.
The need for WiMax Deployment
It is evident that this technology offers many benefits over other wireless and wired technologies due its reliable broadband connectivity. However still we observe it is not deployed as a major communication by some of the countries of the world. The reason is that people and nations still consider it an expensive and difficult to operate technology. Its widespread deployment is still limited to the large scale government projects. The reason is that it is assumed that it requires huge investment and all other benefits related to its use are neglected. In my view it can be really beneficial for the areas which are under developed and which lack the basic telecommunication infrastructure. WiMax technology can be deployed in the areas easily where it is almost impossible to take wired broadband connections. It is really simple to operate that even a single WiMax base station is all that is needed to provide connectivity to SOHO ().
The Deployment of WiMax in Dense Areas
As a vivacious wireless technology it can support the small and medium sized enterprises located in the dense areas. However the deployment in some cases is limited due the spectral inefficiency. It is difficult for the WiMax signals to carry on in the regions with very low density. On the contrary the importance of it cannot be overlooked, because it is possible to increase the range of WiMax. The multipurpose WiMax antennas are employed on different WiMax towers to increase the range and strength of WiMax. An example of licensed radio spectrum frequency which provides sufficient penetration in the areas with low density is 2.5GHz.This popular WiMax technology is able to cater emergency deployment needs in areas where the existing communication link has been broken down. For example it served the communication needs of people affected by Katrina typhoon in Florida in 2005.
