The function is documented as: Retrieves the downstream bandwidth for this network in Kbps. This always only refers to the estimated first hop transport bandwidth.
It is returning a guess based solely on the Radio Access Technology and is tuned for the radio in the device. It does not take into account the network your attached to or any variability based on cell congestion or signal quality issues. This make information is somewhat inaccurate and is mostly there as a guide so app developers don't need to know the relative value of many RAT technologies when thinking about bandwidth. If you had been on 1xRTT you would have gotten a much lower number. LTE could have offered the higher number but you were on slow LTE apparently. This is WAI.
