Gbps impulse radio (IR) ultra-wideband (UWB) transmission over 100 meters multi mode fiber with 4 meters wireless transmission

Abstract

Abstract:We present experimental demonstrations of in-building impulse radio (IR) ultra-wideband (UWB) link consisting of 100 m multi mode fiber (MMF) and 4 m wireless transmission at a record 4 Gbps, and a record 8 m wireless transmission at 2.5 Gbps. A directly modulated vertical cavity surface emitting laser (VCSEL) was used for the generation of the optical signal. 8 m at 2.5 Gbps corresponds to a bit rate -distance product of 20; the highest yet reported for wireless IR-UWB transmission.

VCSEL-based gigabit impulse radio UWB for converged wireless sensor and communication in-building networks

“…2, for the UWB bit sequence '101100'. While photonic UWB generation through direct modulation of VCSELs has been demonstrated before at 850 nm over 100 m of multi-mode fiber 4 and at 1308/1564 nm over 1 km of single mode fiber (SMF) 5 …”

Radio-over-Fibre Techniques and Performance

“…Compared to silica MMF, graded-index plastic optical fibres (GI-POF) offer further advantages such as smaller bending radius, better tolerance to tensile load and stress, and simpler connectorization. A RoF system employing VCSEL direct modulation of impulse-radio UWB signals in the 3.1-10.6 GHz band has been demonstrated over 100 m MMF (Jensen et al, 2009). Error-free operation employing FEC is achieved at a wireless distance of 8 m at 2.5 Gbit/s or 4 m at 4 Gbit/s.…”

10Gb/s ultra-wideband wireless transmission based on multi-band carrierless amplitude phase modulation

“…UWB wireless transmissions is identified as an alternative option in the wireless technology industry [4], [5] and have attracted significant research interest [6]- [10]. UWB communication systems can provide data rates of several Gbit/s [6]- [8] while maintaining very low level of power emission.…”

“…UWB communication systems can provide data rates of several Gbit/s [6]- [8] while maintaining very low level of power emission. To the best of our knowledge, the current record of an UWB wireless transmission compliant with the regulations of the United States Federal Communications Commission (FCC) is 4 Gbit/s over a distance of 4 m [6].…”
