Noted 4G signal is strong but data transmission is slow. How is this possible ?

I signed up for an mobile internet package. It was verified and confirmed coverage is good. However, upon verification using speedtest, it is showing less than 1 Mbps, most of the time. This is measure from 500m away from the tower at circa 120m from ground level.

At the same spot, but at ground elevation, speedtest reveals data download at 8 to 10 Mbps.

How can this be explained technically ?

    Because 4G cell signals are mostly directed at ground level to about the 12th floor level. Hence, those living in high-rise buildings above the 12th floor or above 40m are not covered. It's a waste of transmission power to beam 4G cell signals high into the sky. 120m high = about the 35th floor of a building.

    ....... 4G cell towers are often located on top of low-rise buildings at a height of about 20m.

      No, 4G cell towers can only beam signals up to only 3 miles away for Internet data and up to 10 miles away for voice calls. Maybe 500m away from the cell tower is too near at 120m height.

    check your phone is set to 4g only that tower likely has gsm 2g and 3g , if gsm or 3 g is a stronger signal your phone may be using that, also if 100s of phones are connected to that tower it will be very slow

    There are tons of variables that could be slowing it down. quick steps are to reboot, then reset network settings (if your phone has that option) it could simply be congestion or an issue with the tower you are connected to also.
