Abstract—A telephone based wireless system for the remote operation of the home appliances is proposed. The telephone‚ acting as a remote controller‚ generates a DTMF signal corresponding to each dialed digit which is converted to a BCD code by the Telephone interface circuit. This is given as input to the transmitter module which is then used to control various home appliances through a receiver module. Data processing stages of the transmitter and receiver modules have been implemented

generating point to the consumers’ end without any physical wire has yet to as a familiar and viable technology. This paper focuses on the past and future possible advancements in WPT and explaining why it has still not come into practical utility. Wireless energy transfer has been around for about a century‚ but as of yet has only found usage in things like electric toothbrush rechargers and specialty applications such as beaming solar power down from space. A simple demonstration of it can be constructed

CONCEPT OF WIRELESS ELECTRICITY (Wi-Tricity) Our forefathers marveled at the invention of glowing light bulbs by Thomas Edison in 1879. However‚ to us 21st centurions‚ the light bulb is nothing out of the ordinary. When computers‚ cell phones‚ laptops‚ iPods‚ etc. were invented our antennas tweaked. Now this is what you call invention! However‚ as time’s progressing we are getting used to these devices. In fact‚ charging all these appliances has become so very cumbersome. Each appliance has its
