BACKGROUND "Airwave" is the new communication system currently being rolled out across the United Kingdom for the police and emergency services, based on the Terrestrial Trunked Radio Telecommunications System (TETRA). Some police officers have complained about skin rashes, nausea, headaches, and depression as a consequence of using their Airwave handsets.(More)
Terrestrial Trunked Radio (TETRA) technology ("Airwave") has led to public concern because of its potential interference with electrical activity in the brain. The present study is the first to examine whether acute exposure to a TETRA base station signal has an impact on cognitive functioning and physiological responses. Participants were exposed to a 420(More)
This paper reports the results of the proof-of-concept developed to demonstrate the centralized full transmission impairment compensation between the central office and the user's premises in long-reach passive optical networks (LR-PONs). The impairment compensation technique uses the information from a broadband channel sounding performed by only nine(More)
This paper presents an innovative high-bandwidth access network architecture that offers transparent transport services for fixed and mobile applications. Key to this is the development of a high-functionality, low-energy active remote node (ARN) offering high-speed switching and statistical-multiplexing features for maximal exploitation of available(More)
Radio-over-fiber techniques apply to fiber-to-the-home distributions to reach the customer premises with the services to be received with full-standard low-cost equipment. Bi-directional coarse wavelength division multiplexing (CWDM) radio-over-fiber transmission of triple-format full-standard orthogonal frequency-division multiplexing (OFDM) signals in(More)
A dual-drive LiNbO(3) architecture modulator with chirp management is proposed and developed offering SFDR > 25 dB in a 1.4 V bias excursion compared to only 0.5 V bias excursion in a conventional Mach-Zehnder electro-optical modulator (MZ-EOM). The architecture effectively extends the linear regime and enables the optical transmission of wireless systems(More)
Wireless and optical integration is pivotal to the exploitation of future access solutions. Optics provides greater bandwidths and long reach while wireless offers easier deployment, mobility and freedom to end users. By combining both, service experience is highly enhanced. Single types of transmission systems indeed have their advantages, but integration(More)
Optical and wireless integration in the same platform is an essential requirement for future access networks in order to achieve an economically feasible business model, especially for the deployment of Next Generation Networks. The combination of both technologies offers high bandwidth together with mobility, thus making a strong contribution to future(More)
