Abstract(s)
This article gives an overview of the European research on Mobile Broadband System (MBS), whose features range from WLANs type scenarios, allowing low mobility and medium data rates, up to public cellular MBS, whre high mobility and data rates are foreseen, leading to plain ubiquity. Current trends in 4G systems are described leading to the defintion of the MBS concept. Owing to high transmission data rate and spectrum limitations at lower frequency bands, MBS intend also to operate at millimetrewave frequency bands, namely the 40 and 60 GHz, offering improves system capacity. The MBS concept and the Trail Platform developed in the framework of the European ACTs-SAMBA and RACE-MBS projects are presented. Cellular planning aspects are discussed including a comparison between the 40 GHz and 60 GHz frequency bands, considering services and applications, tele-traffic, and MBS optimisation based on economics aspects. Field trails resutls on the radio interface performance are presented, demonstrating MBS cellular operation feasibility at millimetrewave frequency bands.
