Abstract: A method of transmission of radio signals over all types of graded-index multimode fibre is provided. The method comprises launching optical radiation into the core of the multimode fibre away from the centre of the core so as to strongly excite a subset of the available modes of the multimode fibre. The subset of modes excited are within a small number of mode groups and thus have similar propagation constants leading to a reduction in modal dispersion and modal interference and smoothing of the frequency response passband region beyond the fibres specified 3 dB base band bandwidth assisting RF transmission and recovery from this region.

Abstract: In a remote management messenger system (RMMS), a method for screening a packet-based call originated from a caller via a caller telecommunication device (CTD) to a receiver telecommunication device (RTD) via the RMMS. The method includes activating, if a receiver associated with the RTD does not respond to the packet-based call within a predetermined time period, an answering-and-recording function (ARF) associated with the RMMS to enable the ARF to receive and record packets pertaining to the packet-based call while permitting the receiver to continue to hear the caller. The method also includes, if the receiver responds to the packet-based call after the ARF is activated, permitting the receiver to continue the packet-based call with the caller.
