Evidence and uncertainty
The installation, location and venue dimensions come from a joint company release. Its claims of powerful, uninterrupted and ultra-low-latency service are not independent measurements, and no test method or baseline is supplied.
Telecoms.com confirms the announcement and explicitly notes the absence of a concrete advanced service. 3GPP material supports the SA, NSA and slicing definitions only; it says nothing about Plaza Norte 2 performance.
The “first” claim is retained only as “first shopping centre in Spain.” Telefónica’s 2023 hotel pilot prevents a broader claim about all indoor 5G SA sites.
