“…For train communication systems, we can use conventional wireless communication technologies such as LTE and Wi-MAX [45]; however, the capacity of the link is relatively small. Millimetre-wave radio transmission technology is sufficiently reliable for critical applications, such as train control.…”

Demand for wireless services is increasing rapidly, due to deep penetration of mobile terminals, such as smartphones. Radio spectrum congestion is an important issue, even for conventional mobile services. One of the possible solutions would be to use wired and wireless seamless networks consisting of radio and optical links, where huge data traffic can be offloaded from radio-waves in the air to optical signals over fibres. This paper provides seamless network configurations which can be applied to 90-GHz high-speed wireless links and high-resolution radars. We focus on applications for public transportation systems including airport runways, railways, etc.

“…A first approach of this analysis has been presented by the authors at [21]. However, the most of the publications had analysed each wireless communication system impact separately [10,22,23]. Therefore, in this paper the impact of interference in MB-OFDM UWB over WiMAX 802.16d on a hybrid RoMMF architecture and a final radio link to the end-user system is presented.…”

“…WiMAX is a wireless transmission technology targeting medium-to long-range data communications [8]. On the other hand, WiMAX applications are addressed to improve the coverage in large wireless local area network (WLAN) installations in special scenarios such as high-speed train communications, indoor broadcasting or in live coverage of massive sports events [9][10][11]. Regarding these features, WiMAX and UWB are expected to coexist in indoor scenarios.…”

Abstract:In this letter the use of hybrid WiMedia-defined Ultra-Wideband (UWB) and IEEE 802.16d WiMAX radio-over-fibre is proposed and experimentally demonstrated for multimode based in-building optical networks with the advantage of great immunity to optical transmission impairments. In the proposed approach, spectral coexistence of both signals must be achieved with negligible mutual interference. The experimental study performed addressed an indoor configuration with 50 μm multi-mode fibres (MMF) and 850 nm Vertical-Cavity Surface-Emitting Lasers (VCSEL) transmitters. The results indicate that the impact of the wireless convergence in radio-over-multi-mode fibre (RoMMF) is significant for UWB transmissions mainly due to MMF dispersion and electrooptical (EO) devices with limited bandwidth. On the other hand, a WiMAX transmission is feasible for a 300 m MMF and 30 m wireless link in presence of UWB, with -31 dBm WiMAX EVM.

“…A discussion around future railway services and bandwidth requirements was presented [14] based on lower frequency wireless technologies, including inter-carriage connection based on IEEE802.11 [21], WiMAX [22], [23] with dedicated short-range communications [18]. Guan et al [14] also pointed out the difficulty of accurately analyzing the on-board bandwidth with respect to the number of active users during peak period, simultaneous communication within certain scenarios, and different service types.…”

The next generation of railway customer-oriented services are expected to generate a large volume of data (≈ 10s of TB). As a result, passengers' applications, safety, security, and Internet-on-Board (IoB) sensors challenge current Train Communication Networks. With the present Ethernet Train Backbone (ETB) specification of just 100 Mbit/s in total, railway passenger services will not support intelligent, seamlessly connected and mobile media on-board trains. In this paper, we propose a novel ETB design with experimental results demonstrating end-toend 10 Gbit/s and 40 Gbit/s throughput results over existing conducting media on commercial railway carriages. This is equivalent to 100 Mbit/s per user on real-world railway rolling stock and shows that standard RailCat 5e cabling and new railapproved 10 Gbit/s ETB active nodes (switches) fully support emerging trends and future-proof ETB configurations.
