Have you ever wondered if there is a difference in cellular network on the ground floor and the top floor of a building? Ookla has published a report that shows that the 5G network experience in some of the world's tallest buildings is highly dependent on the equipment used.
Therefore, the Petronas Twin Towers are among the buildings that have a large difference in 5G network strength when on the ground floor and the top floor. The 5G network is satisfactory on the ground floor with a reading of -80.44 dBm but drops to -92.67 dBm on the top floor. This is because there is no 5G equipment used in the world's tallest twin building.
In addition to the Petronas Twin Towers, large differences in 5G network strength were also detected in South Korea's Lotte World Tower, and Indonesia's Autograph Tower.
The buildings with the best 5G networks in the world are Shanghai Tower, Burj KHalifa and Lotte World Tower. The 5G technology used by local telecommunications companies allows for a good average 5G signal compared to other tall buildings. Lotte World Tower doesn't have a consistent 5G network throughout the building, but the network strength on the ground floor is still among the best in the world.
Interestingly on this list, The Shard in the United Kingdom has the weakest 5G network despite the UK being a developed country.
