                           Conclusions

 • HSWC and Lund University are committed to radio
   technologies needed for 802.11ad

 • A new effort is starting in 60 GHz
       – Channel modeling
       – RF technology
       – Antennae for handheld and notebooks


 • Industry-and-research collaboration is key to
   Productization
                                                Next Generation High Speed Wireless Communication
