With around 80% of mobile traffic originating indoors, and higher frequency 5G spectrum struggling to penetrate buildings (which in turn are becoming increasingly impenetrable due to the use of new building materials) the demand for indoor coverage solutions is growing.
Historically, in-building systems were provided to large, high footfall buildings by the MNOs for their own customers.
Mobile operator funding is however limited to the prime buildings with large corporate customers and this model left many buildings unserved, and even then it’s unlikely they’d have multi-operator systems. With the current flight to quality in commercial real estate and for landlords wanting to fill their buildings with long-term tenants, multi-operator mobile connectivity is essential, not a nice to have.
