Radio over Fiber Technology

Abstract

Radio over fiber is an analog transmission in which radio frequency is modulated with laser diode. It is an integration of wireless and fiber optic network .Today the peek requirement is capacity of the channel so optical communication has come in picture. The future provision of multimedia and broadband the radio over fiber systems are good option. In this paper, four signals are transmitted for 120 km. through single mode fiber with erbium doped fiber amplifier. Two base stations are introduced at 40 km. each to add and drop a particular signal. The well known advantages of fiber such as low loss, light weight, large bandwidth, small size, low cable cost are very useful in optical communication. Warless sensor network is used where battery recharge or replacement is impossible so network life time is more important. In this paper we are presenting a heterogeneous network in which various energy efficient technologies are used .It is an essential technology for the provision of access to broadband wireless communication in a range of application. Their transmission properties are very useful in their implementation as the backbone of a wireless network.
