摘要 |
The invention relates to a plurality of user equipment (A, B, ..X) and to a piece of headend equipment (1) which are connected via the electrical network (2) by means of an ascending channel and a descending channel. The inventive method essentially offers the following: access to multiple pieces of user equipment (A, B, ..X) via the ascending channel and the sending of multiple information frames sent by the headend equipment (1) via the descending channel, in a simultaneous manner using OFDMA/TDMA/CDMA multiplexing; a criterion that is used to dynamically assign each carrier in such a way as to maximise the transmission capacity of both the ascending channel and the descending channel; a quality of service that can be adapted according to the type of information and the user requesting the transmission; and a dynamic allocation of the bandwidth by means of a calculation and the constant monitoring of the signal/noise ratios. |
