Senza Fili Sparring Partners

The 6GHz band has become prime estate: a large amount of spectrum that can be safely shared with incumbents and used for indoor connectivity and densification in high-traffic areas. Understandably, everybody wants to use it and protect their access to it: mobile operators, other service providers, enterprises, public entities, and everybody in their homes. Who should have access to it? How should we ensure coexistence with incumbents? And how should we protect the right to access the

We are still in the 5G and 5G Advanced phase, but it is good to take a peek at where 6G may take us in the evolution towards an open RAN – and possibly beyond what we now call Open RAN. In this Sparring Partner, I talked with Ravi Sinha at O-RAN ALLIANCE about multiple RAN evolution paths from 5G/5G-A to 6G that will open the RAN beyond the fronthaul interface.

We had many Sparring Partners on energy efficiency in wireless, but none was on Wi-Fi. This is a glaring omission since Wi-Fi accounts for the majority of wireless traffic – in most countries, it hovers at around 80% of wireless traffic. Yet, there is much less data (and debate) on Wi-Fi energy efficiency than on 5G or LTE – and there are reasons for this. Claus Hetting at Wi-Fi NOW helped us fill this gap in the next Sparring Partners. We debated on the energy efficiency of Wi-Fi, and on how it
