Brief history of evolution of mobile communication throughout entire world is useful in order to appreciate fabulous impact that cellular radio and PCS will have on all of us over next several decades. Progressive involvement in technology development is very crucial for any government if it hopes to keep its own country competitive in the rapidly growing field of wireless communication. As time passed we developed so much advanced technology which was never been possible before. After second generation tremendous revolution occurred with third generation technology in communication and it is known as cdma2000. After that various sub technologies came into existence of cdma2000. These are based on Interim Standard 95 and Interim Standard 95B technology. Similarly for other technology OFDM and UWB we developed lot of advanced technology as per need of clients. Our main focus to develop this technology is that cost effective, less complex, maximum subscriber, high quality of service. As we know information is transmitted through electromagnetic waves with help of antenna. Which types of antenna are best suited for a particular technology is tedious task. Now days we are using smart antenna. We can say smart antennas are arrays of antenna which consist multiple transmitter antenna and multiple receiver antenna.
