WIRELESS ENERGY TRANSFER

[attachment=18350]

HISTORY
First wireless technology was used by Alexander graham bell in 1880 for conversation. On June 3rd, 1880 Alexandra bell transmitted the first wireless telephone message on his newly invented “photo phone”
“Photo Phone” a device that enable sound to be transmitted on a beam of light , bell and his assistant “Charles Sumner Tainter “developed the photo phone using a sensitive selenium crystal and a mirror , that would vibrate in response to a sound
In 1881 , they successfully send a photo phone message over 200 yards from one building to another .
“Bell” regarded the “ Photo Phone “the greatest invention I have ever made, greater than the telephone”
“Alexander graham bell’s” reveals the principle upon which today’s laser and fiber optics communication system are founded ,thought it would take the development of several modern technologies to realize it fully
Among them wireless energy transfer through high frequency signal are more compatible and economical way of transferring different forms of energy



Present scenario
From Alexander graham bell‘s invention of “Photo Phone” to present mobile communication system our technology outwitted many field of success
The most significance among them is the wireless energy transfer mechanism
The various fields in which wireless technology is being used are
1. MOBILE COMMUNICATION SYSTEM
2. RADIO BROADCASTING
3. TELEVISION BROADCASTING
4. SATTELITE COMMUNICATION


MOBILE COMMUNICATION

Mobile technology has already creating hype throughout the world. We are using so many features in our mobile these days which most of us have never dreamed off. What is making all these amazing features working so well? We are using SMS, deliver messages in seconds throughout the world with just a little click of button ”Send”, MMS, sending pictures and video files in amazingly quick time, finding locations, accessing high speed internet in your mobiles are the features which were not possible just few years back, there are some technologies which are actually responsible for such facilities on our mobiles and we are going to talk about all these technologies in mobile communication section
Today’s mobiles networks supports features likes SMS, GPRS, MMS, emailing facility on mobile, Bluetooth, WAP and many more depending upon how reputed and bigger mobile network company is, most of the networks worldwide provides these features as they have become the standard features in mobile communication between their customers and of course one cannot neglect how sophisticated mobiles phones are available now, these mobile phones carries many features which sometimes are not supported by mobile networks. Mobile phones of today’s age are now equal to portable PCs. These mobile phones connect to their cellular networks and these cellular networks are connected to Public switching telephone network (PSTN).


Mobile Network Technology

Mobile Technology has groomed a lot in past few years, major reasons for rapid advancements in mobile network technology is requirements for being mobile or connectivity on move. Latest mobile handsets offers features which one had never thought off, ultimately it forces mobile network companies to bring these features in practice use to take commercial advantages.

Cellular companies use AMPS, D-AMPS, CMMA2000, UMTS, GSM, EVDO etc. AMPS however pretty much vanished from the scene, AMPS network system was based on analog communication technology, latest features were not supported by AMPS therefore all cellular networks worldwide have adopted above mentioned digital communication methodologies to meet the need of consumers. GSM remains the highly used
