When I searched for interfacing arduino with gps module on youtube , I found there is a genius using bluetooth module to send signal to gps and fool the gps as a magic:
And when I downloaded his code from github, there is nothing about the bluetooth module. I wonder if it really possible. Because from what I learn from the text book, the bluetooth has 2.402G~2.480G, whose central freq is 2.441G while the gps has 1.5 ~ 1.8 G.
Am I wrong about this? Or should I assume that the bluetooth module he used are capable of generating signal within the gps signal range?

No, and you shouldn't assume anything about the bluetooth, other than that Bluetooth is Bluetooth.
But you might be wrong in your understanding of what is going on. It would appear that Arduino is feeding false NMEA data to the phone. This does not mean it is sending a GPS signal, and, in view of data being data, sounds like the sort of thing one might do via Bluetooth.
This would seem to be more of an exercise in phone programming rather than an Arduino project.
