        Progression and Potential:  The DSA Highlights the


        Importance of the 6 GHz Band for Unlicensed Access

        and Wi-Fi 6




                                                              Wi-Fi  6  will  increase  network  efficiency  by

                                                              same network.


                                                           According to Ofcom UK, the growing use of Wi-Fi is causing heightened
                                                           expectations from consumers as to the capacity of their broadband as
                                                           they begin to access ultrafast and full-fibre technology. This comes as
                                                           a result of the arrival of innovative applications such as Augmented
                                                           Reality  (AR),  Virtual  Reality  (VR)  and  Ultra  High  Definition  video  in
                                                           residential, corporate and public environments. As the popularity of
                                                           wireless devices increases among society, so too does the demand
                                                           for  connectivity,  high  throughput  and  low  latency.  The  6  GHz  band
                                                           presents a golden opportunity to address such demand immediately.
                                                           Making  this  band  available  for  Wi-Fi  and  other  related  wireless

                                                           innovative applications and address some existing problems of slow
                                                           speeds  and  congestion.  For  example,  Wi-Fi  6  will  increase  network
                                                           efficiency by more than four times and deliver up to 40% higher peak
