The wireless technologies are now everywhere, the development in his sector has taken it up to the standard to provide very high speed internet and mobile phone operations. Now it is possible to combine one or two wireless technologies to increase its service and efficiency. There are many types of wireless technologies like WiMax, WiFi, Bluetooth and infrared technologies. The wireless communication can take place via radio, infrared and microwave communication. The wireless applications include point to point and multi point communications. WiFi is a LAN technology which provides the facility to convert wired LAN to wireless LAN. The wireless technologies are either already incorporated into the devices or they are made compatible by installing wireless interface cards. WiMax is the next generation wireless technology aiming to overcome the deficiencies in the previous wireless systems. the reason why the wireless technologies is considered cost effective is because for employing wireless technology one does not need to change or replace existing wireless equipments. WiMax technology is also the most efficient of all the others of its type because it is aim to cover wide area networks. It can cover the range of 50 kilometers. Bluetooth technology has already replaced the need for pen drives and it is still capable of replacing wires in a LAN network.
Expectations from Wireless Technologies
The word pervasive communication or ubiquitous is the future expectation of not only the enterprises but also the individuals. It is this term which gives an emerging platform to producers of wireless technology compatible products and services. Every wireless technology is expected to be everywhere always 24/7 to avail the various facilities. TV broadcasting on mobile phones everywhere, very high speed broadband connectivity for users all around the world, mobile roaming at cheaper prices, real time video conferencing and calls and portable wrist sized mobile phone sets. Hence the various expectations of wireless technology are not attached entirely to the wireless broadband internet access but also to the digital gadgets. The future accounts for the complete lay down of wires from home offices and computer networks. The emergence of 4G is expected to give rise to wireless MAN by merging various WLANs present in one city. The cost of carrying and maintaining wireless networks is decreasing that is why it can replace wired technologies.
The Future Challenges for Next Generation Technologies
We are standing in the era where it is possible to have voice chats and video conferencing in even remote areas but still there are many challenges that hinder the way of wireless success. The main challenge is that how to make current network architecture compatible with next generation technologies like 4G. This is the reason why 4G has not been widely adopted. The next generation technologies are modified to provide long term benefits to the technology carriers. If we look at the current Korea we would find that this region is entirely different from our world. They can make use pervasive communications throughout their country. While most of the countries in the world including USA is also looking forward to adapt to these changes in future. Hence we can say the wireless technology challenges can be overtaken without additional network modifications. All we need is government and individual support at all levels just like Korea.
