Overview and Analysis of UWB signal for Low Power WPAN

Abstract

In modern short range wireless applications, RF, Bluetooth and UWB communication schemes are recommended with respect to power consumption, low/high data rates and location capability. Though special bandwidth is not allocated to UWB, coexistence of such signal in the available RF environment is a critical issue and hence analysis of UWB signal with respect to interference is very much required in dedicated WPAN networks. In this paper, effect of UWB interference for existing systems such as GPS, FWA, UMTS, DCS1800 is analyzed. Communication path distance is directly proportional to the UWB signal pulse width. To correctly define the UWB signal this functionality is realized by composing UWB signal and results are simulated using MATLAB.

Influence of Various Technologies on the Quality of Ultra-Wideband Antenna on a Polymeric Substrate

“…Ultra-wideband is a comprehensive term that refers to short-range wireless technology that consumes low power and transmits data over a wide bandwidth (more than 500 MHz or with a relative bandwidth greater than 20%) in the frequency range of 3.1 to 10.6 GHz [ 1 ]. A high transmission rate can be achieved by combining a large bandwidth covering the majority of the radio spectrum with an appropriate modulation (such as Pulse Position Modulation (PPM), Pulse Amplitude Modulation (PAM), Bi-Phase Modulation (BPSK), Code Division Multiple Access (CDMA), or Orthogonal Frequency Division Multiplexing (OFDM)) [ 2 ]. UWB technology has a wide range of applications, including data transmission and sensor data collecting in modern networks, such as WPAN (Wireless Personal Area Networks) for interconnecting electronic devices [ 2 ] and WBAN (Wireless Body Area Networks) for continuous health monitoring [ 3 ].…”
