THE FUTURE OF WIRELESS

Going wireless is a term that is often used these days around the world. 10 years ago almost
everything was connected via a wireline system. Technology evolves very rapidly and wireless
communication is no exception to this. The future of wireless technology is bright due to it being very
cost efficient and very easy to use. The fact that you don’t have to worry about wires and cords all over
the place or being tangled up in wires might not sound like much but it is a huge benefit of wireless
communication, and when you think about it is really the main reason we are moving towards a future
using wireless communication systems. We have seen wireless technology in cell phones and radios.
However, this technology has many other practical uses which can revolutionize the future. In
straightforward and simple words wireless technology is a rapidly changing, low cost and simple to
handle technology.
Light waves, sound waves, compression waves, electromagnetic energy, microwaves, radio frequency,
infrared light, visible light, acoustic energy and ultraviolet light are just a few of the wireless
technologies available today. Specifically in the wireless networks industry, radio systems, such as
mobile phones and wireless internet connections, have become an integral part of modern life.
However, today's devices use twice as much of the radio spectrum as is necessary. New technology is
being developed that could fundamentally change radio design and could increase data rates and
network capacity, reduce power consumption, create cheaper devices and enable global roaming.
Wireless technologies are now everywhere, the development in this 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, WI-Fi, 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. 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 equipment’s.
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.
Usually we think of mobile phones or using the internet when talking about wireless technology.
However the future of wireless is not just limited to these two areas. Future wireless technology also
includes laser communications systems. Similar to fiber optic communication, laser communication
involves using a beam of intense light that travels through space or a specific area. Laser communication
or light-based communications is visible (and invisible) light that has a frequency of between 400 and
800THz (800 and 375nm). in cases where you really don’t want radio interference, such as hospitals,
airplanes, and other sensitive environments, visible light communication (VLC), is really rather desirable.
satellites and planes, or any space vehicle that can travel to the Moon, Mars, Venus, the Sun and other
celestial bodies will expand their use of lasers for communication as well as defense against objects in
space be it space junk, asteroids or even other Earthly and non-Earthly spacecraft. There can be many
practical users for lasers. Recently, scientist in Taiwan have developed an infrastructure that simply uses
green and red light to make a 1Gbps wireless network. This is about 10 times faster than the average
802.11n Wi-Fi___33 router, and covers distances of up to 25 meters, for around a price of $600.
In medicine, wired technology is already transitioning to future wireless technology. Since the neurons
in the brain work by electrochemical reactions these can be used by people with disabilities to control
computers in the present. Right now, some wires are involved, but in the future this will become a
completely wireless situation. In the medical science lab and on the brain surgeon's operating table,
electrodes are still used to gather information and to heal patients. Future wireless technology dictates
that one day not too far ahead of us this will become totally wireless as well. Different types of energy
will be used in place of invasive electrodes to further science in the lab and help heal people in hospitals.
Some other wireless areas to watch as they emerge are superconducting technology, high altitude
platform systems, Wireless Sensor Network technologies and super WiMAX technology. Future wireless
technology will expand upon all of these areas. Scientists and engineers are working on wireless
recharging of electric cars. Researchers are currently developing a solar / wireless recharging system for
roadways that will use renewable energy to recharge vehicles as they pass over the recharging panels
embedded in the road.
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. To build a better wireless future, we’re going to have to build better
wireless networks. If we don’t we’ll be forced to reverse one of the biggest technological gains of the
21st century: disconnecting the world from wires.
